THE HUNGARIAN DAISY AS AN ADULTERANT OF INSECT POWDER.

By G. M. Beringer, A. M., Ph.G. Read at the Pharmaceutical Meeting, December 18th.

A short time ago, there was received in New York a consignment, consisting of a number of bales of these Hungarian Daisies. They were entered at the Custom House as insect flowers and were evidently intended as a sophistication of the Dalmatian Insect Powder. In the course of business, a sample of these flowers was submitted to the writer.

The similarity in size and general appearance to the flowers of the Dalmatian powder, would easily deceive the careless or unguarded observer. On close inspection, however, with a microscope of ordi- nary powers, the differences in the botanical structure are such as to render the distinction between the whole flowers comparatively easy. But as they will, probably, in future importations, be mixed with the genuine, which, usually, as imported in bales, are very much broken up, they will prove a dangerous adulterant, one difficult to deter- mine, and if in the powdered article most likely beyond detection.

The Dalmatian Insect Powder has proven so superior to the Per- sian powder, that it has driven the latter almost entirely out of the market. It is said to be the most valuable product of Dalmatia and is now imported in very large quantities. As imported, it is usually adulterated with the ground stems and leaves of the plant. The lat- ter being cut down at the end of the season, dried, ground and mixed with the ground flowers in the proportion of one to three or four of the flowers. This accounts for the fact, that the whole flowers are-

usually quoted at the same price and frequently at an advance on the price of the powder. The adulteration of this product with Hungarian Daisy, is deemed of such importance as to be worthy of record and prompt exposure.

The present editions of the Dispensatories contain but indifferent descriptions of this drug. The following descriptions are offered with the hope that they may serve to distinguish the two.

Hungarian Daisy. Stems angled, the dried flower heads averaging about half inch in diameter, the rays florets being twisted and folded. When soaked in water to their natural size, the flower heads average 1J inch in diameter from tip to tip of the ray florets. The involucre broadly campanulate imbricate, the scaly margins chaff-like, the stem being deeply inserted makes it distinctly depressed or concave ; green- ish-grey in color, glabrous. (Fig. 1 represents the involucre, the dried flower enlarged two diameters.)

The ray florets, (about 18), white ligulate, nerved, three toothed pistillate; the appendages of the style extending beyond the tube. The achenia angled without pappus, but crowned with a faint margin. (Fig. 3 A represents the ray floret enlarged about three diameters.) The disk florets numerous, bright orange yellow, tubular, five toothed, the stamens included ; achenia without pappus. (Fig. 3 B represents the disk floret enlarged about seven diameters.)

The botanical characteristics of this flower would indicate that it most probably belongs to the sub-genus Leucanthemum ; but, with only the flowers for examination, the naming of the species would be but a guess of little or no value.

enlarged about four diameters.) The florets of the true insect powder are somewhat larger than those of the Hungarian Daisy.

The Hungarian Daisy is distinguished from the true Pyrethrum by the orange yellow disk florets, by the depression of the involucre, by its prominent dark receptacle and the absence of pubescence and pappus. The odor is less pungent than that of the true insect flower being more like that of matricaria. The difference in odor is more pronounced on infusing in warm water. The Hungarian Daisy yields a powder, somewhat darker in color. This powder used upon flies and cockroaches appeared to have no value as an insecticide. Micro- scopically no difference could be detected between the two powders.

Time and the amount of material at my command would not per- mit of a thorough chemical examination, but it was hoped that the percentage of extractive matter obtained with various solvents might furnish a useful comparison. The following statement exhibits the results obtained.

Read at the Pharmaceutical Meeting, December 18th.

The following description of the above plant, together with the ma- terial for analysis, has been furnished by Dr. V. Havard, U. S. Army Surgeon, at Fort Abraham Lincoln, Dakota :

" Lewisia rediviva, called " Spathum " by the natives of Northern California and South Oregon, and "Chita" by those of Northern Ore- gon. The " bitter root " of the whites in the Rocky Mountain re- gion.

tion to its wonderful vitality ; prepared specimens have been found, after months and years, sprouting in herbariums, and have, even then, been planted successfully.

" It is a small stemless herb with linear leaves, smooth and fleshy, densely imbricated on the short, thick caudex. From the cluster of leaves spring one or more jointed scapes, one or two inches long, each bearing a showy flower. Sepals 6-8, light pink, broadly ovate, mem- branous, persistent. Petals 8-1 0, rose colored, oblong, often an inch long, at length twisting around the stamens and pistil. Stamens numerous. Capsule globose, 1 -celled, separating transversely at the base, containing many campylotropous shining seeds borne on long funiculi which spring from a central placenta.

" This plant blossoms early in May and through June and part of J uly. After the middle of July (according to Dr. C. C. Parry) the scape breaks off at the joint and the flower is blown away, leaving no trace of the plant exposed to view until the following spring develops the cluster of leaves by which the Indians are guided in procuring their supplies of this palatable and nutritious root.

" It is common, often abundant in the Rocky mountains and west- ward to the Pacific, on dry prairies and in mountain valleys. Its vast habitat comprises the southern part of Washington territory, Ore- gon, Idaho, Western Montana (where it gives its name to the Bitter Root Mountains), Northern California, Nevada, Utah, Western Wyoming and Northern Arizona.

" The natives use the roots as an article of food. These roots, 3 or 4, or more, curled and twisted, spread out laterally and are generally superficial. As they spring from the caudex they are rarely half an inch in diameter and are seldom thicker than a goose quill ; they taper gradually to a length of two to four inches when they branch off into small radicles. The bark is brownish externally, bright red within and very bitter, it is quite possible that it might possess useful tonic and astringent properties. The inner part of the root is white and farina- ceous, containing in the centre the yellowish pith. This white part is quite palatable and said to be very nutritious, a single ounce of the % dried article (according to Dr. E. Palmer) being sufficient for a meal. Eaten raw it has a slight bitterish flavor. According to Nuttall, it almost dissolves into starch by maceration in cold water. If boiled in water, it forms a substance similar to boiled arrow-root. The In- dians, generally, boil it with other esculents into a soup.

The roots of the above plant as received by me were free from bark, of a white color, and ready for use as food. No evidence of sugar as glucose or saccharose could be obtained. Tests for tannin likewise gave negative results. The most important constituents are starch, gum and mucilage, the last two are not readily precipitated by alcohol. The following summary gives the amount of the most important food constituents.

The amount of starch found may appear small when we consider the uses of the root, but the large amount of gum and mucilage make up for this deficiency.

THE LEAVES OF MAGNOLIA GLAUCA, LINNfi.

By Wilbur Fisk Kawlins, Ph. G.

Abstract from a Thesis.

The leaves are three to six inches long, one and a half to two inches in width, have a prominent mid-rib, are pinnately veined, ellip- tical, petiolate, coriaceous, deep green upon the upper side and of a beautiful glaucous color underneath. Twenty pounds were collected in the early part of September. After drying they weighed eight pounds, the loss being sixty per cent. They were then reduced to a number eighty powder.

Two grams of the drug heated in an air-bath at a temperature of 110° C. lost ten per cent., and when incinerated left 10 per cent, of ash.

Fifty grams of the powdered leaves were placed in a flask, covered with petroleum spirit and, after maceration, exhausted ; five per cent, of the drug was soluble in petroleum. This residue when heated to 110° C. lost four-tenths per cent. Absolute alcohol left four-tenths of one per cent, of insoluble waxy matter melting at 64° C.

The drug was then treated with stronger ether, which dissolved four per cent. The dry extract was treated with boiling distilled water and lost three-tenths of one per cent. It gave a bitter taste to the water, but yielded no precipitate to tests for alkaloids. On evaporat- ing the ether there were formed some fine needle-shaped crystals. The extract was dissolved in alcohol, the chlorophyll removed by animal charcoal, and several attempts were made to obtain the crys- tals in a purer state, but without success. There was, however, a resin present that had a tendency to crystallize.

Absolute alcohol was the next menstruum used, and the extract ob- tained was five per cent, of the drug. About one and a half per cent, was soluble in water. The portion that did not dissolve in water was a greenish-yellow powder and had a lasting unpleasant taste. Tan- nin was found in the soluble portion, but the percentage was not de- termined. The aqueous solution was made acid and agitated success- ively with petroleum, benzol and chloroform. It was then made al- kaline and the same treatment repeated. The resulting liquids were evaporated, but nothing found in the petroleum or benzol. There was a deposit of crystals, however, from both the acid and alkaline liquid with chloroform. Nothing else of importance was found in the alcoholic extract.

The residue, after exhaustion with alcohol, was macerated with water, which dissolved thirteen per cent, of the drug, containing mu- cilage, coloring matter and ash, but no sugar, nor anything else of spe- cial importance.

The residue insoluble in water yielded to solution of caustic soda mucilaginous substances and albuminoids amounting to four per cent.

Diluted hydrochloric acid dissolved two per cent, of the drug, and of this six-tenths of one per cent, was oxalate of calcium. No starch was found.

On treatment with chlorine water the loss was six per cent, lignin ; and with chlorate of potassium and nitric acid the loss was two per cent.

Three pounds of the fresh drug were distilled with water. From the distillate, by shaking with ether, was obtained a volatile oil of a bright green color with a penetrating odor, resembling that of fennel or anise, but more pleasant. The yield was very small, about one drachm being obtained from the three pounds. While the solution of

oil in the ether was filtering the rapid evaporation of the ether caused crystals to form on the edge of the filter, but they soon volatilized and no examination was made of them.

In order to determine the nature of the crystals formed by the use of chloroform from the aqueous solution of the alcoholic extract, one pound of the original drug was packed in a percolator and exhausted with wood alcohol ; the alcohol was recovered by distillation and dis- tilled water added to the residue ; the solution was filtered and agi- tated with chloroform, but crystals were not obtained. These extracts had a bitter taste, imparted fluorescence to the chloroform solution and after boiling with acid, reduced Fehling's solution. The principle seems to differ from the magnolin of Mr. Procter.

Note by the Editor. It does not appear to be generally known that the fresh leaves of Magnolia glauca may be used in the place of indelible ink for the marking of linen and other fabrics, by placing upon the latter the lower surface of a leaf, and tracing upon the upper surface with a blunt peg, using some pressure, the desired characters. The writing appears upon the fabric at first of a grayish green color, which gradually becomes darker, and does not disappear on washing.

METHYSTICIN FROM PIPER METHYSTICUM.

By Robert Glenk.

On evaporating an alcoholic tincture of the root to a small bulk, a crystalline precipitate forms, which is obtained snow-white on dissolv- ing in boiling water (to separate resin) and allowing to cool. This principle is the methysticin first observed by Morton, in 1844, and further examined, in 1860, by Cuzent, Gobley and O'Rorke. Crys- tallized from alcohol, it forms fine needles, which are odorless and tasteless, and freely soluble in ether, benzol and benzin ; very soluble in boiling alcohol, slightly soluble in the cold ; soluble in about 60 parts of boiling water, but sparingly soluble in the cold, separating as a crystalline feathery precipitate. Its solution in hot water is of a neutral reaction, and is not precipitated by alkaloidal reagents.

When placed in a test tube kept in mercury, the principle melts at 133°C; by heating on platinum foil it burns with a smoky flame, and is finally consumed without residue. It does not reduce an alkaline solution of copper.

Concentrated sulphuric acid forms immediately an intense carmine

color, which changes to a brown in one or two hours. Concentrated nitric acid dissolves it with a reddish-brown color. Concentrated hy- drochloric acid gives an orange red color.

With oxidizing agents, like permanganate of potassium, chromic acid (K2Cr207+H2S04), or nitric acid, it is decomposed, with the pro- duction of a strong heliotropin-like odor, which is quite characteristic, being produced even in very dilute solutions. A cold solution of methysticin in diluted alcohol, on being boiled for a few seconds with dilute nitric acid, gives a decided odor of heliotrope. This does not occur with other oxidizing agents in such dilute solutions.

The color, with concentrated sulphuric acid, is also quite character- istic, a bright carmine red being produced, in rather dilute solutions, on adding to four or five drops of the latter about ten drops of the acid.

Gallic acid. Specimens of gallic acid from different manufacturers Avere procured by Fred. Win. Meissner, Jr., Ph. G., and subjected to the pharmacopceial tests. The saturated aqueous solutions yielded no precipitates with an alkaloidal salt, albumen or gelatinized starch, but produced heavy white precipitates with a solution of tartar emetic and ammonium chloride. Even in very dilute solutions of gallic acid a distinct precipitate was obtained by this test, and previous continued washing with cold water did not prevent the precipitation. Gallic acid was then prepared by Liebig's process from tannin by boiling with sulphuric acid, recrystallizing and decolorizing with animal charcoal, remaining traces of tannin being removed by solution of lead acetate, as suggested by Watt. The crystals thus obtained answered all the pharmacopoeial requirements ; the result may, per- haps, have been caused by the presence of a slight amount of acetic acid. The albumen and alkaloid tests are regarded as sufficiently delicate for the detection of tannin in gallic acid, one part in thirty being easily indicated.

Five samples of gallic acid on being heated to 100° C. lost re- spectively 9*5, 9'6 9-75, 9*75 and 10*5 per cent, of water.

In other respects the two powders showed no difference.

phide, a slight black precipitate, and the filtrate a slight white precipi- tate with ammonium phosphate. Sodium was the remaining base found, and besides carbonic, no other acid could be detected. The powders consist of commercial sodium bicarbonate, one of them being colored with a little carmine.

An analysis of a so-called invisible toilet powder was made by Owen C. Spear, Ph. G. Ether dissolved the volatile oil, and on evaporation left a trifling amount of fatty matter. When ignited the odor of burn- ing sugar was given off. Cold water took up nothing ; on boiling with water and cooling a gelatinous liquid was formed, which turned blue with iodine. After exhausting with boiling water, the residuary pow- der did not blacken when ignited ; hydrochloric acid dissolved a por- tion of this residue, containing Zn and a little Fe, Al and Ca, but no other metals. The undissolved powder was ignited with Na2C03, then treated with water and HC1, when the presence of silica and magnesia, with traces of Fe and Al was shown. The toilet powder proved to be a mixture of starch, talc, zinc oxide and calcium carbonate.

For quantative analysis the powder was ignited and the starch esti- mated by the loss. Treatment of the residue with HC1 left the talc undissolved ; the solution treated with ammonia yielded a precipitate, which after ignition was weighed as Fe203 and Al2Os. From the am- moniacal filtrate the zinc was precipitated by NH4HS, converted into chloride, precipitated as carbonate, and weighed as oxide. The lime was precipitated from the mother liquor, and weighed as carbonate. The analytical results were :

Starch 18 02

Talc 49-42

Alumina and ferric oxide 1*37

The toilet powder was probably made by mixing together commer- cial starch 18, talc 52, and zinc oxide 30 parts.

12 Analysis of Market Jellies. {Am"jSf,iSfrin-

ANALYSIS OF MARKET JELLIES.

By Lysander Mann Jones, Ph. G. From an Inaugural Essay.

It has been asserted that the jellies found in the market are not pure fruit jellies as represented and that they are principally com- posed of gelatin and glycerin. Although my analysis has proved that they are fruit jellies, at least some of them are not made from the fruit which they are supposed to represent, but are made from some cheaper fruit artificially colored and flavored.

Taking as a standard a currant jelly known to be pure and home- made, I have analyzed six different jellies purchased in the market, namely : apple, currant, cranberry, grape, pineapple and raspberry and compared these with the genuine. Of these I found the grape to be the only genuine and made from the fruit represented. The commer- cial ones differ considerably in color and taste from the genuine ; the genuine being of a deep red color and having a very pleasant, sweet, fruity and acidulous taste while the commercial present a much nicer appearance being of a bright red color and more transparent, but have a flat, ropy and but slightly acidulous taste and are not as sol- uble.

The standard jelly was composed of 26 per cent, water, 36.5 per cent, glucose, 32.5 per cent, saccharose and 1.3 per cent, pectin. The remaining 3.7 per cent, consists of insoluble matter, malic and tartaric acids. The pectin was gotten by adding alcohol to a given weight of jelly in a concentrated aqueous sol utiou, collecting the precipitate on a filter, drying and weighing. The ash of 2 grams amounted to 5 milli- grams or .25 per cent.

The commercial currant jelly I found to be composed of 45 per cent, water, 18.46 per cent, glucose, 13.84 per cent, saccharose and .7 pectin. The remaining 22 per cent, consists of insoluble matter, tar- taric acid, artificial coloring matter, etc. The ash of 5 grams amounted to 17 milligrams, or .34 per cent.

The genuine had a strong acid reaction, while the commercial jellies had but a faint acid reaction with the exception of the grape.

On evaporating an aqueous solution of the market jellies an odor was given off resembling baked apples, thus proving the source from which they are made. The absence of gelatin was proven by no pre- cipitate forming on the addition of tannin, while the presence of pectin

as the base was proven by means of a solution of sub-acetate of lead.

The principal adulterant found in the market jellies, except in the the grape, was the artificial coloring. On making an aqueous solution of about 5 grams, evaporating this to the consistency of a syrup and to this adding about 100 cc. of alcohol and warming slightly, the pec- tin would be precipitated and the coloring matter taken up in the al- cohol. This was filtered and to the filtrate was added small pieces of raw silk and wool and boiled for some fifteen minutes. The result was the silk and wool took up the coloring and were dyed of a light red color. The coloring in the genuine would not act in this way.

In testing the genuine jelly for pectin with solution of sub-acetate of lead, the coloring matter was precipitated with the pectin, while in the commercial jellies it remained in the solution, the pectin being separated as a light flesh colored precipitate.

The market jellies in solution did not present a perfectly clear li- quid, but on the addition of ammonia water the color deepened con- siderably and the solution became much clearer.

Glycerin was not present in the jellies. This was shown by precipi- tating the pectin with alcohol, filtering, evaporating nearly to dryness, treating this residue with one part ether and two parts alcohol, filter- ing, evaporating to dryness and testing this with the borax bead. Metals were absent with the exception of a little iron.

EXAMINATION OF CHLORINATED LIME.

By Hermann M. Schroeter, Ph. G.

A Contribution from Chemical Laboratory of the Philadelphia College of

Pharmacy.

Read at the Pharmaceutical Meeting, December 18th.

Chlorinated lime as a commercial product is variable in composition. It is therefore valued by the percentage of available chlorine which it contains. The Pharmacopoeia requires at least 25 per cent, of such available chlorine. The following examination of this article will show the average value of same as found in the market, both in bulk and in packages. That in ready put-up packages is generally con- tained in pasteboard boxes, the insides of which are coated with resin, or else in sealed tin cases. Small and large packages were procured, as also several samples in bulk, of which 18 kinds were examined. The method used was that recommended by the Pharmacopoeia or the

modification of Bunsen's iodometric method. It consists in determin- ing voluruetrically by titration with sodium thio-sulphate, the amount of iodine which is liberated in an aqueous solution of chlorinated lime when potassium iodide and hydrochloric acid are added in excess. The Pharmacopeia directs 071 gm. of chlorinated lime mixed with a solu- tion of 1 *25 gms. of potassium iodide in water and 9 gms. of dilute hydro- chloric acid added, should require not less than 50 cc. of the volume- tric solution of sodium hyposulphite. This corresponds to 24*93 per cent, of chlorine. The following figures give the mean percent- ages of chlorine of several determinations of each sample :

. 1. 25*73 per cent. 7. 31-11 per cent. 13. 29'17 per cent.

6. 37-84 " 12. 28-17 " 18. 36'46

Nos. 1, 2, 3, 4, 14, 15, 16 and 17 were obtained in bulk. Nos. 6 and 12 were lib packages and the balance were smaller parcels. The above figures give an average percentage of 29*83 per cent, of chlo- rine, showing the superior strength of the commercial article. From lib. packages determinations were made severally from different parts of the parcels, the difference in results being only slight.

PEKMANENT SYPUP OF HYDRIODIC ACID.

By Joseph W. England, Ph. G.

Read before the Pharmaceutical Meeting, December 18th.

H Hydriodic acid as a remedial agent first came into vogue some thirty years ago through Dr. Buchanan, who strongly urged its use as an alterative. Since its introduction it has found a limited and varying demand amongst the medical profession.

There seems to be good grounds for believing that its failure to meet popular favor may have largely been due to the fact that the so- lution is exceedingly unstable, unless well protected by sugar and kept in close-stoppered vials. Even then it has been a most unsatisfactory preparation, pharmaceutically, tending readily to decomposition, on ex- posure to air, into free iodine and water, the former of which, by its presence, rendered it a local irritant instead of an alterative.

Of late, however, there seems to be a tendency to return to its use,

Am'ja0nuyi^9arm'} Permanent Syrup of Hydriodic Acid. 15

especially as there are now obtainable in the markets a number of syr- ups of hydriodic acid claimed to be unalterable on exposure to air.

Various preservative substances are used to achieve this end, such as honey, potassium hypophosphite and hypophosphorous acid ; gly- cerin has little or no influence in retarding decomposition.

The new National Formulary (p. 122) gives a formula for the prep- aration of a colorless hydriodic acid syrup, prepared by double decom- position between potassium iodide and tartaric acid in the original way, but preserving it from oxidation with potassium hypo-phos- phite.

This formula, in its practical workings, is most excellent and, in the writer's opinion, superior to the pharmacopoeial process of iodine and sulphuretted hydrogen. There is one point in it, however, upon which criticism might be turned and that is the presence of the potas- sium hypophosphite, or, what is more probable, hypophosphorous acid, since some acid tartrate of potassium still remains in the finished solution unprecipitated, but the quantity of this salt used, is so small that this feature, practically, need not be regarded.

The writer has used this formula since last August, with but one modification in detail, and that was the substitution of syrupy glucose for potassium hypophosphite, as the preservative. A sample of some made last August is as clear and destitute of free iodine as some made yesterday. The modified formula is as follows :

Iodide of Potassium 123 grains.

Tartaric Acid 112 "

Water | fluidounce.

Diluted Alcohol 1

Syrupy Glucose £ "

Syrup, enough to make 16 "

Dissolve the iodide of potassium in one-half (J) fluidounce of water and the tartaric acid in one-half fluidounce of diluted alcohol. Mix the two solutions in a vial, cork and shake it well, and then place it in ice-water for about half an hour ; again shake it thoroughly, and then pour the mixture upon a small white filter, and filter into a bottle con- taining 13f fluidounces of syrup and one-fourth (J) fluidounce of syrupy glucose. When the liquid has run through, wash the vial and filter with one-half (J) fluidounce of diluted alcohol, added in several portions. Then add enough syrup to make sixteen (1 6) fluidounces.

The product is a clear, transparent, almost colorless liquid, odorless,

having a pleasant acidulous taste, and evincing no free iodine, on the addition ot cold gelatinized starch. It remains unchanged on expos- ure to air. Syrupy glucose is used in place of the solid compound, be- cause it is more convenient and fulfils the same purpose. One peculi- arity noticeable with its use is the fact that syrups of hydriodic acid made with it, and containing, at first, free iodine, from faulty manip- ulation, become, on standing for a day or two, colorless from the conversion of the free iodine, by the glucose, into hydriodic acid.

Rhamnus Frangula in Odontalgia. Dr. Gretchinsky writes to the Revista de Med. y Farm., that he makes a decoction by boiling 15 to 30 gm. of the bark in 2 tumblers of water. Patients are directed to rinse the mouth with this every five minutes until the pain ceases ; and then every two hours. Cavities may be filled with cot- ton dipped in the tincture. Repert. de Ph., November.

Papayotin in Fissure of the Tongue. Schwimmer is said to have used this substance successfully in cases which had resisted the action of chromic acid, iodoform and nitrate of silver. He employed the following formula : Papayotin, 1 to 2 parts ; glycerin and dis- tilled water, of each 10 parts. Five or six applications should be made daily, after drying the fissures.

Benzoinated Gray Oil. Beausse places 20 gm. of mercury in a matrass and adds 5 or 6 gm. of ethereal tincture of benzoin, with brisk agitation. When the globules are no longer visible the tincture is decanted and the vessel re-corked and again agitated. The mer- cury forms a soft paste on the sides of the vessel. All the material is then put in a mortar with 10 gm. of vaselin and 30 of liquid vasel- in and well triturated, adding also the washings of the matrass with ether. " The preparation requires a labor of four or five hours." Arch, de Ph., Nov. 5.

Naphthol Ointment. Used for skin diseases, this ointment should contain, according to Dr. Lassar, about 10 per cent, of naph- thol, to which in obstinate cases 10 per cent, of camphor may be added. The naphthol ointment may remain in contact with the skin

from one-half to one hour ; the camphorated compound must be re- moved within about 15 minutes.— Arch. Med. Belg.; Monit. Th., Nov. 5.

Peepaeations of Sozoiodol. A 5 to 10 per cent, solution re- tards the development of pyogenous cocci ; 10 per cent, solutions pre- vent the development of microbes ; 20 per cent, solutions render gel- atin sterile. In doses of 1 gm. sozoiodol is not toxic to rabbits. For open wounds, 2 or 3 per cent, solutions of the acid (diiodoparaphenol- sulphonic) with the salts of sodium or aluminium is used. For a prolonged action the sozoiodol of potassium is mixed dry with pow- dered talc or milk sugar in quantities of 5 to 10 per cent. For oint- ments, sozoiodol of potassium, sodium, aluminium or lead may be used in the proportions of 5 to 10 percent., with lanolin. For insuf- flations, the sotlic or potassic salt is mixed with sugar of milk. The same is true of the zinc salt which may contain 1 to 10 per cent. ; and the mercury salt, which should be made with 5 to 10 of the latter to 90 or 95 of sugar of milk. Nouv. Rem., Nov. 24.

Unna's Topical Applications in Skin Diseases. Dr. Hallo- peau in a recent visit to Unna, learned that he has been engaged in perfecting these applications, which are recommended in three forms : medicated paste ; ointments spread upon muslin, and plasters similarly prepared. The paste, used as a vehicle, prolongs the action of the medicaments, retains the secreted water upon the surface of the skin, augments cutaneous respiration and quiets irritation. The applica- tions are intended for prolonged use without re-dressing. The soft paste of Unna is made as follows: Oxide of zinc, 15 ; glycerin, 15; gelatin, 25 ; water, 25. The muslin plasters are prepared by making the fabric impermeable with caoutchouc dissolved in benzol or the oleate of aluminium. M. Vigier in recent experiments on the prep- aration of the plasters gives the preference to a coating of soft paraffin mixed with gutta-percha dissolved in bisulphide of carbon. Unna's paste, spread on these plasters, or used as an ointment, is said to " ren- der great service in the treatment of pruritus, eczema, intertrigo and acne." R. Blondel, J. de Ph. et de Ch.y Dec. 1.

Toxic Power of Strophanti**. Prof. See in a communication to the Academy of Medicine (Nov. 13), said that the strophantus plant or its extracts only, should be used in medicine ; strophantin, he said, had so high a toxicity that it " must not be employed clinically. " At the same meeting, Dr. Dujar din-Beau metz also recommended that stro- jphantin be prescribed in no case, " as the quantity of strophantidin contained in it must, for the present, be more or less conjectural." [The samples of strophantin which seem to have frightened the Paris faculty are said (Un. Med., Nov. 15), to have been made by M. Ar- naud, chief of M. ChevreuPs laboratory.]

Incompatibility of Cocaine and Borate of Sodium. In a paper to the Soctite de Pharmacie, M. Levaillant said «that in mixing these substances for collyria or gargarisma he had found a precipitate of cocaine. This will disappear on the addition of a few drops of glycerin. Arch, de Ph., Nov. 5.

Reaction of Phenacetine. Chlorinated water gives the aque- ous solution a red-violet color which soon passes to ruby red. A solu- tion of chloride of lime will give the same reaction. Arch, de Ph. Dec. 5.

Eschscholtzia Californica. According to a recent examination of this plant by M. Bardet, (J. de Ph. et de Ch., Dec. 1), its narcotic power is weak ; doses of 10 to 12 gm. of the extract were necessary to kill a rabbit. In seeking the active principle, the author took up the extract with acidulated water and treated it with ammonia, which gave a viscous product capable of reducing iodic acid, a violet precip- itate with molybdate of sodium, and an orange color with nitric acid ; briefly, it offered the reactions of morphine. This is the first time, so he believes, that morphine has been obtained from plants other than papaver L. After extracting the morphine, another substance remained which gave a yellow precipitate with phospho-molybdate. It ap- peared to be a glucoside. M. Bardet is now studying it.

1 That Walz found in Eschscholtzia in 1844 sanguinarine and two other alkaloids was mentioned in Amer. Journ. Phar., 1887, p. 296.

Reactions of Certain Alkaloids with Fluoniobate op Potassium and Chlorine in Sulphuric Acid. The fluoniobate reagent is prepared by dissolving 1 gm. of the salt in 40 ccm. of con- centrated sulphuric acid, and then heating to drive off the hydrofluoric acid. With apomorphine, this solution gives a very intense red, slight- ly brownish, which becomes of an ochre yellow color on adding water. Morphine acts in the same manner, but the coloration is weaker. The chlorine reagent is easily prepared by saturating concentrated sulphuric with pure, dry chlorine. With this, narcotine gives a very beautiful violet coloration, which passes rapidly to wine-red and yellow ; heated slightly, the mixture becomes red. Narceine turns of an olive green color which turns gradually blue, with streaks of red. Brucine takes a red color, as with nitric acid. A. I. Brociner, in J. de Ph. et de Ch.; Union Ph., October.

Action of Hypobromite of Sodium upon Certain Aromatic Derivatives ; and Differential Reaction Between Hippuric and Benzoic Acids. If hypobromite of sodium containing an ex- cess of alkali be boiled with hippuric acid, gaseous bullae are disen- gaged and the liquid clouds with a reddish-yellow tint. The precipi- tate, which goes down on cooling, appears as a powder of a kermes-red color. Benzoic acid under like conditions gives no reaction. Glyco- col causes a decoloration of the hypobromite, with a disengagement of azotic gas. Testing the action of hypobromite of sodium upon a large number of azotized products of the aromatic series, the following re- sults were obtained : Benzamide and Benzonitril gave nothing when cold ; on ebullition, gave a kermes-red precipitate. Aniline ; the aqueos solution even when largely diluted gave an orange precipi- tate ; the reaction was nearly as sensitive as that of the hypochlorite of lime. Methylaniline ; a yellow precipitate slightly greenish when cold, but becoming red on boiling. Toluidine ; same results as for ani- line; the precipitate is browner. Anilides ; nothing with cold; on boiling, a reddish precipitate. An odor of cyanide of methyl is disen- gaged. Hydrochlorate of diamine-metaphenylene, diamido-benzoic acid, diamine-toluilene ; all gave hot or cold a red maroon precipitate. Ferrocyanides, ferricyanides, nitro-prussiates ; on boiling, all gave a red precipitate of ferric hydrate. Pyridine; no reaction. Quinoleine ; does not give the orange-red precipitate except which is frequently the case aniline is present. Acad, des Sci.y cvii, 662. 1888 ; J. de Phar. et de Chim., Dec. 1, 1888.

GLEANINGS FROM THE GERMAN JOURNALS. By F. X. Moerk, Ph. G.

Carbohydrates in urine. N. Wedenski, by precipitation with ben- zoyl chloride in presence of NaOH, obtained the compound ethers of two carbohydrates, of which one was decomposed by boiling with ex- cess of NaOH ; the other was not acted upon by this reagent but was afterward easily decomposed by boiling with dilute H2S04. The former corresponds to the compound ether of the starch group, the latter to the glucose group. Fehling's solution is reduced by the lat- ter, but only after treatment with dilute acids by the former ; this also answers to the test for animal gum found by Landwehr in urine by precipitating with copper sulphate, washing, drying, dissolving in HC1 adding alcohol when the substance is reprecipitated, especially on warming to 60°. Ztschr. f. Physiol. Chemie, xiii, 122.

Digitalis ambigua, which in some countries is more common than D. purpurea, contains according to Paschkis, the same constituents found in D. purpurea. Following the method of §chiniedeberg he obtained digitonin, digitonein, digitoginin, digitalin, digitalein and digitoxin. In an aqueous extract chrysophanic acid was detected. The me- dicinal properties of the two drugs are identical. Apoth. Ztg., 1888, 869.

Diphenylmethylpyrazol analogous in composition with antipyrine and used for the same purpose, is made by the action of benzoyl-acetic ether upon phenyl-hydrazine and then introducing the methyl group. It forms white needles melting at 150°, is difficultly soluble in water and ether, easily soluble in alcohol and glacial acetic acid, and differs from antipyrine in being a strong base ; also in the reactions with ni- tric acid and with ferric chloride, these not being so characteris- tic.— (Ztschr. f. Angew. Chem.) Pharm. Centralh., 1888, 463.

Iodoform in its behavior towards ether differs considerably, some brands marked absolute giving with this solvent dark colored solu- tions owing to liberation of iodine, probably due to an impurity of the iodoform which is decomposed by ether. Neuss, Pharm. Ztschr. f. Russl., 1888, 681.

Antiseptic sponges for gynaecological operations. The sponges are placed for 2 hours in a solution composed of corrosive sublimate 1*0, carbolic acid 5*0, alcohol 60*0, water 500*0 ; after expression they are allowed to dry in the air and may be impregnated with one of the fol- lowing solutions : I. Boric acid 15*0, boiled water 500 ; II. Tan- nin 30, boiled water 500*0; III. Solution ferric chloride 40" 0, boiled water 500.0.— Pharm. Centralh., 1888, 558.

Filicic Acid. G. Daccomo prepared the acid by agitating the ethe- real extract (oleo-resin) with a mixture of two volumes 95 per cent, alcohol and one volume ether, which precipitated the acid as a brown resinous mass. After purification a glistening, odorless pale-yellow crystalline powder was obtained, melting at 179-180°. Heated above 100°, it assumes a golden color, taking the original color again on cooling. Insoluble in water, sparingly soluble in absolute alcohol ; more soluble in glacial acetic acid, ether, amylic alcohol and toluol ; easily soluble in chloroform, carbon disuiphide and benzol. Its form- ula is CHH1605. Heated in a sealed tube to 170-190°, it is decom- posed into isobutyric acid, and a red substance, having the formula C20H18O7. C14H16O5+H2O=C4H8O2+C10H10O4. Two molecules of the last substance, by loss of one molecule of H20, give the compound C20H18O7. By oxidation with K2Mn208, and also with HN03, butyric and oxalic acids are formed. If the compound C20H18O7 be allowed to stand several days with HN03, from the solution can be obtained pearly scales, melting between 198° and 202°, sublimable, the subli- mate melting at 127-129° ; by analysis found to be phthalic acid ; oxalic acid is also formed by this oxidation. These reactions indicate that filicic acid is the isobutyrate of oxynaphthoquinone. Ber. d. d. Chem. Ges., 1888, 2962.

Cantharides. Baud in has found that this drug appears in the mar- ket, partially deprived of the cantharidin by extraction with a men- struum containing sulphuric acid ; the ash then contains an undue amount of sulphate. In determining the cantharidin, he recommends it to be carried out in two stages ; first, exhausting with chloroform, which removes the free cantharidin, and then with chloroform con- taining 2 per cent. HC1, which dissolves the combined cantharidin. Cantharides contain about 1 per cent, total cantharidin, 0*72 per cent, free, and about 0*3 per cent, combined. Apoth. Ztg., 1888, 921.

Cotton-seed oil in olive oil. E. Hirschsohn discovered that a chloro- formic solution of auric chloride (1 gm. in 200 cc.) gave on warm- ing with cotton-seed oil an intense raspberry-red color, while pure olive oil with the same reagent gave no reaction. To apply the test, 3 to 5cc. of the oil with 6-10 drops of the auric chloride solution are placed in a water-bath and heated to 100° for twenty minutes. Cotton-seed oil develops the color in a few minutes; of other oils tested hemp, linseed, poppy, almond, olive, rape, turnip, mustard, sesamum, sun- flower, peach-kernel and grape-seed oils gave no reaction ; peanut and castor oils gave a slight deposit of metallic gold without imparting any color to the oils. The addition of 20 fo cotton-seed oil to the drying oils could not be detected, while the addition of 10 % could be detect- ed in peanut, poppy, turnip, castor, olive, sesamum, almond and sun- flower oils. The prettiest tests were gotten with olive, sesamum and almond oils. Further experiments with olive oil proved that the ad- dition of one per cent, of cotton-seed oil could certainly be detected by the method given above. By noticing the depth of color and the time required to produce it approximate results can be obtained. —Pharm. Ztschr.f. Russl, 1888, 721.

Hj droclilorate of Apomorplilne has been extensively tried by Dr. Socquart, of Brussels, as a remedy for certain kinds of cough, particularly in distressing and frequent hacking, unattended with expectoration, or with ex- ceedingly difficult expectoration.

The dose is only about one-twentieth grain, given in water in the twenty-four hours. As the solution rapidly alters by keeping, it is advised to prevent its decomposition by the addition of a few drops of hydrochloric acid, which does not interfere with the therapeutic effects.

24 Densimetric Estimation of Albumin in Urine. {Am'ja(^fimarm'

DENSIMETKIC ESTIMATION OF ALBUMIN IN URINE.1

By Zahoe.

Although it has been shown that from the theoretical side there is much to be urged against the densimetric method, yet it is found in practice, in cases where accuracy to the first place of decimals is sufficient, that the method is extremely quick and handy. This is felt nowhere so much as in estimations of albumin in urine, and the following method is simple, and can be carried out clinically :

The filtered urine is mixed with just so much dilute acetic acid that when it is boiled all the albumin is coagulated ; the right proportion may be ascertained with a small quantity of the urine in a test-tube beforehand. On being filtered from the coagulum, the filtrate should give no cloudiness with acetic acid and potassium ferrocyanide. A quantity of the urine is then placed in a flask firmly closed with a clean caoutchouc stopper. The flask is hung for 10 or 15 minutes in a large bath, filled with water kept boiling. By this means the albumin is precipitated. It is then filtered off, the funnel leading through a cork with a hole in it into a flask, and being covered with a glass plate. The density of the urine and the filtrate is then estimated, not with a pycnometer (that is unnecessary for clinical work), but with an arao- meter marked to four places of decimals. Both fluids must be kept at the same temperature. This is best done by placing them in two cylinders, both immersed in a large vessel of water, which should be kept at the same temperature if a series of observations are to be made. The temperature of 17#5° degrees will be found most convenient. The difference between the two specific gravities is then multiplied by 400, and the product gives the number of grams of albumin in 100 cc. of urine.

A large number of illustrative experiments are quoted, in which the approximate accuracy of this simple process is demonstrated. The number 400 is the mean in round numbers of the factor

retically but also in practice it yields fallacious results in other albu- minous fluids, such as the blood, transudations, white of egg, etc. The reason is that the factor must be multiplied by the difference in the specific gravities. In proteid solutions (other than albuminous urine) this difference varies from 0*0016 and 0*0128, whilst in albuminous urine this difference is much smaller, varying between 0*00012 and 0*00200 ; that is, in the former case the difference is from 6 to 13 times greater than in the latter, and therefore so many times greater will be the error introduced by the use of a constant factor. In the case of urine, this error may be neglected.

ON THE ACIDS OF GASTRIC AND INTESTINAL

JUICES.1

By Dr. Poulet.

The author's method of obtaining the acid principle of the stomach and intestine consists in dialyzing either the contents of the stomach or intestine obtained from an animal in full gastric or intestinal digestion, or the scrapings of the gastric or intestinal mucous membrane. After dialyzing for twenty-four hours, the resulting liquid is evaporated at a gentle heat down to about thirty grams, and then treated in a wine- glass with sulphuric acid. In the case of the stomach of the pig and man hippuric acid in abundance crystallizes out ; in that of all car- nivorous animals, tartaric acid, whilst tartaric acid is found to be the acid separated from the intestine. It would be tedious to follow the author through the exposition of his methods and results at any length. His conclusions have certainly the charm of novelty, but many objec- tions present themselves to his method as a means of obtaining the free acid secreted either in the stomach or intestine. It will be sufficient to give his conclusions as summarized, and to refer for details to the original paper.

The gastric juice of omnivorous adults, and notably of healthy men, contains, in the first stage of digestion, hippuric acid alone. Towards the end of the digestive act a mixture of hippuric and tartaric acids is found. The latter is alone found in the secretion of the mucous mem-

brane of the empty stomach. Before weaning, tartaric acid is the chief acid found. Since tartaric acid has been found to be the acid secreted by all carnivora, recourse must be had to the pig, which in its dental and digestive system corresponds with man, in future experiments.

In dyspeptic men, a quarter of an hour after eating, tartaric acid and hippuric acid were found together. It may be conjectured that in grave diseases of the stomach hippuric acid may be entirely replaced by tartaric.

In all the cases examined in healthy or sick men, and also in ani- mals, no lactic or sarcolactic acid was found.

The hippuric acid of the gastric juice possesses all the properties of that extracted from the urine of herbivora in crystallization, physical aspect, and reduction to benzene by dry distillation with caustic potash, mixed or not with quick lime. But the tartaric acid of the gastric juice differs from the vegetable acid in some of its properties, especi- ally in that it is attacked and decomposed in the cold by concentrated sulphuric acid.

The reactions of dialyzed gastric juice on coloring matters differ very much from those of hydrochloric acid. On the contrary, they resemble either those produced by hippuric acid or tartaric acid. The yellow color of Uffelmann's reagent, which has been attributed exclu- sively to lactic acid, may be just as well due to tartaric or hippuric acid, and is not characteristic, therefore, of the former.

When a dilute solution of hydrochloric acid is added to Gunzburg's reagent, and it is heated, a red color appears, at a temperature of 75° to 78°. A similar color is produced by hippuric acid, but at a tem- perature of 105° to 108°. It is, therefore, incorrect to assert that only inorganic acids produce the red color, and that Gunzburg's solu- tion is the reagent for hydrochloric acid. When normal gastric juice is used it is not at 75° that the red coloration appears, as would be the case if it contained hydrochloric acid, but the temperature must be raised to 105°, precisely that at which it is acted on by hippuric acid.

The intestinal juice is acid in the whole extent of the small intes- tine during the period of intestinal digestion. The principle which acidifies it is none other than the same tartaric acid which is secreted by the mucous membrane of the empty stomach, in young animals dur- ing lactation, and in adult carnivora during digestion.

CHEMICAL OBSERVATIONS ON TARTAR EMETIC.1

By Prof. Dunstan and Miss L. E. Boole. Communication from the Research Laboratory of the Pharmaceutical Society. 1. ON SOME STATEMENTS IN THE BRITISH PHARMACOPOEIA.

For the determination of the antimony in tartar emetic the phar- macist may be supposed to rely on the process described in the British Pharmacopoeia. " Twenty-nine grains dissolves (sic) slowly but with- out residue in a fluid ounce of distilled water at 60° F. (15*5° C), and the solution gives with sulphuretted hydrogen an orange precipitate which when washed and dried at 212° F. (100° C.) weighs 15*1 grains."

These instructions stand in need of considerable amendment to ren- der them of any service in practice. Unless the solution is first acidified, oxy-salt is invariably carried down with the sulphide, and this together with free sulphur, will cause the result to be higher than that which is demanded by the known composition of the salt. Acid tartrate of potassium is also precipitated, and it is difficult to remove the whole of this salt from the precipitate unless it is washed with an unusually large quantity of water. Further, it is extremely difficult to filter the finely divided sulphide, in fact, it is almost impossible to do so, unless the liquid containing the precipitate is boiled for some time ; but this generally leads, when free acid is present, to the de- composition of some of the sulphide, and in this way error is intro- duced. Again, antimony sulphide cannot be completely dried at 100° C. A small quantity of water, about two per cent., is obsti- nately retained, and is only lost with difficulty at a higher tempera- ture ; indeed, according to Fresenius, even at a higher temperature a current of carbon dioxide is necessary to effect its entire expulsion. It is chiefly for these reasons that chemists in general have long since abandoned the method of directly weighing the antimony sulphide, and yet the process is adopted, as a test of purity, in the British Pharmacopoeia without any allusion to these various sources of inac- curacy. Lastly, it should be observed that the amount of antimony sulphide represented by the Pharmacopoeia as obtainable from 29

grains of tartar emetic is 15*1 grains, whereas the quantity demanded by the formula of the salt (SbOKC4H406, iH20) is only 14*67 grains.

2. THE VOLUMETRIC ESTIMATION OF THE ANTIMONY IN TARTAR

EMETIC.

Having regard to the extensive employment of tartar emetic in medicine, it is clearly desirable that a trustworthy and simple method for its quantitative analysis should be available for use by the phar- macist. A volumetric process has been proposed which involves the use of standard solutions of bleaching' powder and potassium arsenite. For the pharmacist this process is inconvenient, since it necessitates the employment of two volumetric solutions which must be specially prepared.

It seemed worth while to attempt to utilize, for a volumetric pro- cess, the decolorization of a solution of iodine, which is effected by a solution of tartar emetic, on the basis of the reaction

SbOK-C4H406+I2+2H20-=2HI+KHC4H406-f-HSb03.

Mohr had already proposed to utilize this oxidation as a volumetric operation applicable to antimonious compounds, and on his recom- mendation the process is not infrequently described in treatises on vol- umetric analysis. The method has been tested by Fresenius, whose results were not quite satisfactory, being in general slightly too high- It appeared desirable that a further trial of the method should be made.

Tartar emetic was several times crystallized from water, and the crystals dried by exposure in a partial vacuum. To establish the purity of these crystals the amount of potassium was determined. As this proved to be a troublesome operation, it may be well to give some account of the different experiments which were made, as well as of the method finally adopted. In order to separate the potassium it was necessary first to remove the whole of the antimony from a solu- tion of the salt. Many attempts were made to effect this removal by means of hydrogen sulphide, but these failed, chiefly for reasons which have already been alluded to. ^Neither was it found practicable to re- move the antimony by the evaporation of a solution acidified with hy- drochloric acid, since a small quantity of antimony was dissolved when the residue, left on ignition, was boiled with water. Simple ignition

of the salt and extraction of the mass with water failed for the same reason. The plan which answered best was to precipitate a solution of the salt with ammonia, which effected the removal of nearly the whole of the antimony as antimonious hydrate, a small quantity being sub- sequently separated during the evaporation of the ammoniacal nitrate. Since ammonium and potassium tartrates remain dissolved it is nec- essary before the potassium can be estimated to ignite the residue left after evaporation. This is accomplished at a low red heat, and the carbonaceous mass is boiled and washed with water, and the potassium finally precipitated as platinochloride in the usual manner, or more simply, the solution may be titrated with an acid solution of known strength. Working in this way, 1*7408 gram of tartar emetic yielded an ash containing 0*3615 gram of potassium carbonate; the quantity of potasbium carbonate calculated from the formula SbOKC4U406, JH20 is 0*3617 gram. Having thus established the correspondence of the crystals with the formula (SbOKC4H406,JH20) they were used in the subsequent experiments. Trials were first made with solutions of tartar emetic acidified with hydrochloric acid, which were titrated with a decinormal solution of iodine, using starch as an indicator. The quantity of hydrochloric acid added was, in each experiment, exactly sufficient to form potassium chloride from the tartar emetic. The dilution of the solution was varied, but without appreciably affecting the results. Although some of the experimental data recorded below agree fairly well with the calculated numbers, yet the method cannot be trusted, on account of the absence of any sharp termination of the reaction, which lags increasingly with each addition of iodine. This difficulty sufficiently explains the discrepancies in the results, which are here recorded :

0-20 100 0 195

Experiments were next made with solutions of tartar emetic to which sodium bicarbonate had recently been added. When this salt is dissolved in a solution of tartar emetic no visible change is observed at first, but after the lapse of a few minutes the liquid becomes turbid,

and gradually nearly the whole of the antimony falls as a white pre- cipitate of antimonious hydrate.

NaHC03+Sb.OK.C4H406+H20= KNaC4H406+Sb(OH)3+C02.

If a solution of iodine is added to the liquid before the precipitation has commenced it is immediately decolorized, and a sharp termination of the reaction is observed. If, however, the solution of iodine is not added until precipitation has commenced, then wholly incorrect re- sults will be obtained, since the precipitated hydrate is hardly attacked by the iodine. To illustrate the importance of accomplishing the re- action before precipitation has set in, an experiment may be quoted in which two solutions of tartar emetic containing precisely the same quantity of the salt were mixed with an equal quantity of sodium bi- carbonate. In the one solution, titration with iodine was immediately performed, when it was found that 18 cubic centimetres of the deci- normal solution of iodine were consumed. In the other solution titra- tion was not commenced until after the lapse of some hours, by which time nearly the whole of the antimony had been precipitated. The mixture was now found to require less than half a cubic centimetre of the solution of iodine to complete the oxidation of the small quantity of antimony compound which had not been precipitated. For this reason, a solution of bicarbonate should be added to the dissolved tar- tar emetic immediately before the titration is conducted. In the ex- periments recorded below from 10-20 cubic centimetres of a five per cent, solution of sodium bicarbonate were employed, and the dilution of the solution was varied. We have not found a large quantity, either of sodium bicarbonate or of water, to affect the chemical change to any appreciable extent. In practice, it will be found that 0*2-0"3 gram of tartar emetic is a convenient quantity to take for each estima- tion.

onate is quite definite, and may be utilized as the basis of a volumetric operation in which solutions of tartar emetic, with sodium bicarbonate, are titrated with a decinormal solution of iodine in the usual manner.

3. ACTION OF ALCOHOL ON AN AQUEOUS SOLUTION OF TARTAR

EMETIC.

When alcohol is added to an aqueous solution of tartar emetic a white precipitate is produced. This has been alleged to consist either of finely divided hydrous crystals or perhaps of the anhydrous salt. The use of anhydrous salt in quantitative experiments such as we have conducted is of much assistance, since the hydrous crystals are liable to alter their composition, owing to efflorescence. We therefore investigated the composition of this precipitate after it had been quickly dried, first at 50° C, and finally in a partial vacuum, over calcium chloride. The white powder was dissolved in water and the liquid was titrated with a solution of iodine. The results obtained were as follows :

Weight of salt Weight of salt found, calculated as taken. SbOKC4H406. 0-1656 0-1657 0-4960 0-4957

They prove that the precipitate, prepared as above described, is en- tirely constituted of anhydrous tartar emetic.

3. THE SPECIFIC ROTATION OF AQUEOUS SOLUTIONS.

The action of aqueous solutions of tartar emetic on polarized light is very rarely alluded to in treatises on chemistry. Solutions of the salt are powerfully dextro-rotatory. Determinations of the specific rota- tion have been made by Landolt and by Krecke. Landolt found that 7*982 of anhydrous tartar emetic dissolved in 100 cc. of water ef- fected at 20° C. an amount of rotation equivalent to [a ]D= +142*76°. Krecke found that a five per cent, solution of tartar emetic at 25° C. effected a rotation corresponding to [a ]D= +138*66°. We have made several determinations at 15° C. with a four per cent, solution of the crystallized salt, using a tube 200 mm. long. The angle of ro- tation under these conditions is +11*3°, whence [a ] D= +141*25°, and for the anhydrous salt under the same conditions +11*4, whence [a ]D= +142*5°. This result is probably in agreement with that ob- tained by Krecke at 25° C, since it is known that an increase of

32 Chemical Observations on Tartar Emetic. {Am jja™yil£arm'

temperature causes a decrease in the specific rotation of this com- pound.

It is a remarkable fact that a solution of tartar emetic possesses a much greater specific rotation than a corresponding solution of any of the commonly-occurring tartrates. For acid tartrate of potassium, for instance, [a ]D= -f- 22*61°. The high specific rotation is therefore characteristic of tartar emetic, and might be usefully employed as a test for the purity of salt. Thus we have found that an admixture of five per cent, of acid tartrate of potassium with tartar emetic reduces the rotatory power of a 4 per cent, solution of the salt to +10*6° (200 mm. at 15° C.) that is for [a ]D + 132-5°.

By means of its action on polarized light a solution of tartar emetic may readily be distinguished from any of the double oxalates of anti- mony and potassium, which are used in dyeing as substitutes for tar- tar emetic, since solutions of these salts are devoid of action on polar- ized light.

4. AN EXAMINATION OF COMMERCIAL SPECIMENS.

It seemed to be of interest to determine the purity of the tartar emetic employed in medicine. Twelve specimens were purchased from pharmacists. The antimony was estimated by titration of the dissolved salt with a standard solution of iodine in the manner pre- viously described. The results were as follows :

ever, that several specimens have yielded more antimony than is ob- tainable from a salt of the formula (SbOKC4HP6,JH20). We have investigated the cause of this anomaly and find it to be due to the ab- sence from the salt of the proportion of water indicated by the usual formula, loss having occurred from the efflorescence of the crystals, which readily takes place when they are kept in air. That this is the cause of the discrepancy was proved by estimating the water in a specimen which had afforded an anomalous result. The specimen se- lected for this purpose was that numbered 1 in the foregoing table, which contained an amount of antimony corresponding to 102"3 of crystallized tartar emetic. This salt, on being dried between 100°- 110°, lost only 0'52 per cent, of water, instead of 2*72 per cent., and by calculating, on this basis, the percentage of crystallized tartar emetic, it is found to be 102*2 per cent., a result which agrees with that obtained by the direct determination of the antimony. The oc- currence of efflorescence to a greater or less extent therefore explains these higli results.

A few specimens afforded results rather below the average, notably the specimen numbered 12 in the table. Xone of these specimens dis- solved completely in the necessary quantity of cold water. Two grams of the specimen numbered 12 in the table were warmed to about 50° C. with 3-1 cc. of water. This liquid when cooled to 15° C. and maintained for some hours at that temperature yielded crystals which were recognized as acid tartrate of potassium. The potassium in the salt was also estimated and found to be higher than that re- quired by the formula (SbOKC4H406,JH20). The rotatory power of a 4 per cent, solution was determined at 15° C. in a tube 200 mm. long. The angle of rotation was 10'5°, whence [ a]D=131*25°, a result which approximately agrees with that which had been previ- ously obtained with a solution of tartar emetic known to contain 5 per cent, of acid tartrate of potassium. It was thus proved that the speci- men contained about five per cent, of acid tartrate of potassium. This specimen, which was in fine powder, had also probably suffered ef- florescence, but we had not a sufficient quantity to determine whether this was the case. Whether this impurity had been fraudulently added, or had arisen from careless preparation of the salt or from a mode of decomposition of the pure sale at present unknown, it is impossible to say. Inasmuch as other specimens which afforded low results like- wise failed to completely dissolve in the requisite quantity of cold

water and also appeared to contain acid tartrate of potassium, it seems not improbable that the crystallized salt is subject to spontaneous de- composition. This supposition is strengthened by the observation that each of these same specimens yielded, when mixed with cold water, more or less of an insoluble residue consisting of antimony ox- ide. Experiments are now being made with pure tartar emetic to test the correctness of this suggestion.

5. THE PREPARATION OF A STABLE SALT FOR USE IN MEDICINE.

It would be a distinct advantage if it were required that the anhy- drous salt should alone be used in medicine. It is, as we have shown, easily prepared pure, and when once prepared it is not, as the hydrous crystals are, liable to spontaneous change, and in addition it is more readily soluble in water. To prepare the anhydrous salt a strong aqueous solution of tartar emetic is precipitated by a large excess of methylated spirit, the precipitate is decanted or filtered, washed with methylated spirit, and quickly dried over a water-bath. The specific rotation of aqueous solutions of this salt has been mentioned in a pre- vious part of this paper. The solubility in water was determined at 15°. It was found that one part of the salt dissolved in 14*53 parts by weight of water.

ISATROPYLCOCAINE.1

By C. LlEBERMANN.

An alkaloid which the author names isatropylcocaine is present in the mixture of amorphous alkaloids obtained as a bye-product in the preparation of cocaine.

Isatropyleoeaine, C19H23N04, is prepared in the pure state as fol- lows : the yellow, sticky, amorphous mixture is dissolved in hydro- chloric acid and the filtered solution extracted with ether. The extract contains considerable quantities of benzaldehyde. The solution is freed from ether by means of a stream of air and the base precipitated fractionally with alkali. It is then obtained in the form of a white, chalky, amorphous powder, the quantity of which is about 70 per cent, of the crude material. The middle fractions are dissolved in hydro- chloric acid, again fractionally precipitated with soda, extracted with light petroleum to remove traces of cocaine, and dried in a

stream of air for several days at the ordinary temperature, and finally at 45°.

The alkaline filtrate from the alkaloid contains ecgonine, the quantity of which is from 1 to 2 per cent, of the crude material.

Isatropylcocainc is very similar to cocaine, but both the base and its salts are amorphous, and the former is not so readily soluble in ammo- nia and light petroleum as cocaine. It is easily soluble in cold alco- hol, ether, benzene and chloroform, but only very sparingly in light petroleum, and in all cases a resinous mass is obtained when the sol- vent is evaporated. It begins to soften at 65°, but has no definite melting point ; at 90-100° it loses water slowly, and at 120° it turns brown and is gradually decomposed. All the salts are amorphous and soluble in water. Picric acid produces a yellow, chromic acid an orange, and potassium permanganate a violet precipitate, which changes to brown. The chlorides of mercury, tin, gold and platinum, and most of the usual reagents for alkaloids, also give amorphous precipitates. The alcoholic solution does not show an alkaline reaction with phe- nolphthalein, and is dextrorotatory.

The base is a powerful poison, but its action is not similar either to that of cocaine or atropine ; the symptoms of poisoning sometimes ob- served after the administration of impure cocaine may be due to this alkaloid.

Methyl chloride is evolved when the base is heated with concentrated hydrochloric acid, and when boiled with strong hydriodic acid methyl iodide is obtained, the quantity of which, estimated by ZeiseFs method, showed that one methyl-group has been eliminated. It is also decom- posed, with separation of methyl alcohol, when heated for a long time with dilute sulphuric acid, but no ethyl alcohol is formed. When boiled for about an hour with hydrochloric acid, sp. gr. 1*1, it is decom- posed into methyl alcohol, ecgonine, and isatropic acid in molecular proportions, as in the following equation :

C19H23N04+2H20-:CH40+C9H15N03+C9H802.

The product of the reaction is filtered and the two isatropic acids in the residue separated by means of their barium salts.

f-Isatropic acid, C9H802, forms about two-thirds of the residue. It crystallizes from 50 per cent, alcohol in small, colorless needles, melts at 274°, and is soluble in hot glacial acetic acid, but only very spar- ingly in ether, benzene and carbon bisulphide. The barium salt,

(C9H702)2Ba, is crystalline, and readily soluble in water. The calcium, copper and silver salts are soluble in water. The ethyl- and methyl- derivatives are very readily formed when hydrogen chloride is passed into a solution of the acid in the corresponding alcohol. The ethyl salt, C9H7Et02, is insoluble in ammonia and sparingly soluble in alcohol, from which it crystallizes in needles melting at 146°. Methyl y-isa- tropate, 09H7MeO2, crystallizes in plates or needles, melts at 174°, and distils at about 300° with very slight decomposition, but has no constant boiling point. A vapor-density determination in anthracene va- por showed that it is at first polymeric, and is only completely transformed into the simple molecule after about half an hour's heating.

3-lsatropic acid, C9H802, forms about one-third of the residue. It is more easily soluble in water than the f-acid, and melts at 206°. Neither this nor the ^-acid yields benzaldehyde when oxidized with potassium permanganate or chromic acid. An aqueous solution of the ammonium salt gives precipitates with calcium chloride, mercuric chloride, and copper acetate. The barium salt, (C9H702)2Ba, is spar- ingly soluble in water. The silver salt, C9H702Ag, is amorphous, but becomes crystalline when boiled with water. The ethyl salt, C9H7Et02, is a viscid oil ; it has no constant boiling point, but after boiling for a long time it distils at 264-270°, and condenses to a color- less, mobile oil. The methyl salt, C9H7Me02, crystallizes from dilute alcohol in prisms or needles, melts at 76°, and is readily soluble in all solvents except water. A vapor-density determination in anthracene vapor showed that it is at first polymeric, but, the transformation into simple molecules takes place much more quickly than is the case with the corresponding salt of the ^-acid.

The acids described above are very similar in appearance and solubil- ity to a-isatropic acid (Lossen, Annalen, cxxxviii, 235), /3-isatropic acid (Fittig, Annalen, ccvi., 34), and the isatropic acids which the author has previously obtained from atropine, but they are not identical with any of these compounds. /9-Isatropic acid seems to be formed when hydrogen chloride is passed into a methyl alcoholic solution of a-isa- tropic acid. Methyl ft-isatropate melts at 91°.

The molecular weight of ^-isatropic acid, methyl and ethyl d-isatro- pate, and methyl and ethyl f-isatropate was determined by Raoult's method in glacial acetic acid solution, and in all cases the results agreed for the molecular formulae given above ; the salts are all repre- cipitated unchanged when water is added to the glacial acetic acid solu-

tion. The acid filtrate from the atropic acids (see above) contains ecgonine and a very small quantity of a complex mixture of acids consisting principally of s-isatropic acid, but in which benzoic acid was recognized. Anhydroecgoniue is also sometimes present. The quantities of ecgonine and isatropic acids are approximately in accord- ance with the equation given above.

Boiling baryta decomposes the amorphous alkaloid in a similar manner to hydrochoric acid, but the ecgonine is partially decomposed.

Other bases occurring with cocaine also yield ecgonine when treated with acids. The author has succeeded in preparing benzoylecgonine from ecgonine.

MASSOI BARK.

By E. M. Holms, F. L. S., Curator of the Museum of the Pharmaceutical Soci- ety of Great Britain.

Some specimens of the barks known in the East under this name, and which were recently presented to the Museum of the Soci- ety by Professor Van Eeden, of Haarlem, may possibly serve to throw some light upon a product concerning which some little con- fusion still exists in commerce.

The name of Massoi appears to be given to three distinct barks, which are identified by Dr. F. Hekmeyer as the products respectively of Cinnamomum xanthoneuron, Bl., Cinnamomum Kiamis, Nees, and Sassafras Goesianum, T. and B. The second is also called by the Malays " Kayu manis sabrang." 1

The first of these, as received from the Haarlem Museum, occurs in pieces about 3 to 4 lines thick, with a thin, uneven, outer dark layer, which is seen under a lens to be composed of stratified cells ; the layer beneath this is granular, the white sclerenchymatous bundles being irregularly arranged in a direction parallel to the surface, except near the inner surface, where they form two nearly regular lines. The portion next the inner surface is darker in color, forming rather more than one-third of the thickness of the whole bark, and shows nume- rous thin medullary rays. It is this portion of the bark that appears to be most oily and aromatic. The odor, when observed at a distance,

1 The name "sabrang3' distinguishes it from the bark Kayu manis (Cinnamo- mum Parihenoxylon) , which is also used by the Malays in colic and diarrhoea- Kayu manis, as represented in the late Colonial Exhibition in London, differs from all the above-named barks in having a somewhat camphoraceous taste.

resembles that of cocoanut milk. The taste is pungent, the flavor somewhat resembling the odor, but also recalling that of a mixture of cinnamon and rue.

The second bark is in quills like cinnamon, but as thick as cassia, somewhat wrinkled externally, extremely hard and woody, and is almost horny in consistence. It has very little odor, but a pungent taste, and a slight flavor between that of cinnamon and cassia. The inner surface is finely striated, and the transverse fracture is dark in- ternally and paler towards the outer surface.

The third bark is thinner than the first, but resembles it in odor. The taste also is very similar, but more pungent and faintly bitter, causing a sensation of heat in the mouth for some time and an aug- mented flow of saliva. The bark is, however, only half the thickness, barely attaining two lines. It is paler in color in transverse section, is marked externally with faint longitudinal cracks, and is more mark- edly striated internally. In transverse section it presents a short granular fracture, the sclerenchymatous bundles being arranged at right angles to the surface, but the middle layer, corresponding to that of C. xanthoneuron in which these bundles are horizontally placed, is scarcely developed. Cinnamomum xanthoneuron and Sassafras Goe- sianum are both natives of New Guinea, and C. Kiamis of Java, Sumatra, and apparently also of Borneo.

All these barks are met with in the bazaars in Java, and are used in cases of colic and diarrhoea and in spasmodic affections.

According to Teysmann and Binnendyk Sassafras Goesianum yields the true massoi bark.

In the Hanbury Collection there is also a bark labelled massoi bark, corresponding exactly in structure, taste, and odor with the bark of 8. Goesianum. It is labelled on the bark, apparently in the writing of Mr. Thos. Hanbury : " This bark I bought at a Kling shop ; they could tell me nothing about it, except that it was used to scent or flavor medicines."

On the outside of the box it is labelled, in Daniel Hanbury's wri- ting, "Cortex Massoi (of ) Blume's 'Rurnphia' (Laurineous ?) bark, smelling like the Brazilian Casca pretiosa.1 Bought at Singapore by Thos. Hanbury, 1853. Found this bark identical with that procured by Guibourt at the Mus6e Japonais, vide Hist, des Drogues, ed. iv.,. torn, ii., p. 383 ; compared the two at Paris, April 22, 1854."

On the inside of the cover of the same box is the following note : " Professor C. L. Blame, in reply to my inquiry respecting this, a specimen of which I sent him, writes thus under date January 5, 1857.

" 2. ficorce ayant P odeur de la Casca pretiosa du Bresil (Sing- apore). C'est Cortex Massoi figure dans la Bumphia, quoique la face interne de votre echantillon soit un peu plus claire, ce qui parait re- sulter de Page de Parbre. Son odeur penetrant, balsamique, tirant sur Pessence de citron, est tres characteristique.1 Je possede de cet arbre de la Nouvelle Guinee seulement les branches avec les feuilles, ce qui me met en etat de dire que c'est bien une Laurinee mais n'ap- partenant pas au genre de Cinnamomuni."

It may be here remarked that it is very difficult to describe an odor, and although Hanbury has identified it with Guibourt's bark, Ecorce de massoy de la Nouvelle Guinee/ Guibourt gives quite a different description of its odor. When the odor, as in the case of Massoi bark, resembles a mixture of odors, it is naturally likened to different products by different observers. Guibourt, in the following descrip- tion of the bark, likens it to cummin.

" Telle que je me la suis procuree a une exposition qui a en lieu il y a quelques annees a Paris, sous le nom de Musee japonais, cette ecorce est cintree, epaisse de 7-8 millimetres, couverte d'un epiderme gris rougeatre legerement tuberculeux et forruee d'un libre gris rose dur et compacte a structure un peu radiee sur sa coupe transversale. Elle possede une odeur tres forte, analogue a celle du cumin, et une saveur tres-acre avec le meme gout de cumin."

I have, however, not depended upon my own opinion alone, but have obtained from more than one observer a corroboration of the opinion that the odor resembles that of cocoanut milk. Leaving, however, odor out of the question, Guibourt's description of the struc- ture of bark corresponds exactly to the bark of Sass<tfras Goesianum of the Haarlem Museum, and as the Hanbury specimen has been identified by himself with Guibourt's, and by Professor Blume, with the bark of the tree described in " Rumphia," there can be no doubt that to this tree the true Massoi bark must be ascribed.

Whether or no this be the massoy bark from New Guinea from which Messrs. Schimmel also have distilled an oil having an odor resembling that of nutmegs and cloves, cannot be ascertained in the

absence of specimens for comparison, but if their description of the odor be correct it is more likely to be the Cortex Culilabani Papu- anus of Martiny's Encyclopaedia, 1, p. 436.

The specimen of this bark in the Hanbury collection has a flavor which might be likened to that of cloves and nutmegs. The bark is, however, quite different in appearance and odor from the true massoi bark,1 being much thicker, softer, somewhat laminated, and not at all radiate in structure. Phar.

THE KOOT OF VERNONIA NIGRITIANA.2

By E. Heckel and Fe. Schlagdenhauffex.

Under the name of batiatior or batjitjor a root is sold in different parts of Senegambia, Avhich is supposed to have febrifuge, emetic, anti-haBmorrhagic, and antidysenteric properties. It has been de- scribed as a substitute for ipecacuanha, and is alluded to as such by Dorvault. It has recently been definitely recognized as the root of Vernonia nigritiana, a composite plant growiug to the height of a foot or two and bears a faint external resemblance to ipecacuanha, which, when fresh, it is said to resemble in smell.

Heckel and Schlagdenhauffen find in this root no trace of any true alkaloid, but they have obtained from it a whitish, slightly hygrosco- pic glucoside, having the formula C10H24O7, which they have called vernonin.

On injecting a solution of the alcoholic extract under the skin of the frog's thigh, paralysis of the limb thus injected followed, the respira- tory movements were interfered with, and the heart's action was ar- rested in the same manner as after digitalis, convallaria, and strophan- tus. On further examination of the heart movements by placing it between the cups of a Marey's cardiograph, it was found that after injecting yVths of a grain of vernonin the amplitude of the heart's movements was first slightly decreased and then increased, but in three-quarters of an hour they fell below normal and became slower ;

eventually the influence of the drug passed off. A larger dose (&ths grain) reduced the number of beats by one-third, the ventricles evi- dently filling slowly. A still larger dose (roths grain) almost ar- rested the heart in systole, diastole only taking place imperfectly and at long intervals ; eventually the heart stopped completely in systole. A pigeon was not influenced by f ths of a grain, but 2J grains killed it, the heart being arrested in systole.

The action of vernonin on the heart thus resembles that of digitalis. Heckel and Schlagdenhauffen, however, consider that it is twenty- four times weaker than the soluble principle of digitalis (digitalein).

They have studied the action of the drug on the skeletal nerves and muscles, and have come to the conclusion that it paralyzes locally nerves to which it is applied, but does not markedly influence the muscles. If the drug be injected under the skin of the thigh it soon comes to pass that galvanizing the sciatic on this side ceases to con- tract the muscles supplied by it, whilst muscles respond equally to the current on the two sides when directly stimulated.

Further experiments are adduced to show that the drug directly destroys the conducting power of the sciatic nerve in the frog, and that in warm-blooded animals it paralyzes the limb into which it is injected. The experimenters, however, have by no means fully shown the influence of vernonin on the nerve and muscle tissues, and some serious sources of fallacy seem to have been overlooked. It may be presumed that a drug which so powerfully influences the nerves must also affect the nerve endings, but no experiments on this point seem to have been made. No means seem to have been employed to prevent the circulation of poisoned blood from the injected to the non-injected leg ; indeed, the investigations would lead to the conclusion that the drug is not thus carried, for it is stated that when the poison is in- jected under the skin of the back, stimulation of the sciatic nerves continues to cause contraction of the muscles. From this it would follow that either the poison does not reach the nerve endings of the leg muscles when injected under the skin of the back, or that it does not paralyze them. Further investigations must be made before the conclusions of Messrs. Heckel and Schlagdenhauffen can be accepted, but they have introduced us to a substance which manifestly has most interesting pharmacological properties and may have important thera- peutic uses.

NOTES ON THE PREPARATION OF DRUG SECTIONS FOR MICROSCOPICAL EXAMINATION.1

By F. Ashley Rogers, Pharmaceutical Chemist.

It is to be regretted that the great majority of pharmaceutical stu- dents of botany and materia niedica, do not prepare their own speci- mens for the microscope, but rely upon the professional rnicroscopist, who is not always a botanist, and has been known to supply the aerial stem labelled root. It would certainly be much more satisfactory in every respect if pharmaceutical students prepared their own objects in the microscopical study of materia medica and structural botany, and I trust that these notes will show the simplicity of the operations and their inexpensive nature.

We may occasionally wish to prepare sections of fresh vegetable tissue. These cannot be cut until they have previously been hardened, which is accomplished by soaking for a week or ten days in pure methylated spirit, which should be frequently changed, say every twenty-four hours, until no color comes away from the tissues. They can now be preserved in spirit, and are always ready for making sec- tions.

But more frequently our drugs are obtained dry, and very hard ; they must then be softened by soaking in water with a little methy- lated spirit, or even soaking in hot water, or in a three per cent, solu- tion of potash (where it can be safely done), that is in cases in which the cell contents, being injured, unfit the section for examination. Sections of soft stems, ovaries, etc., may be made by hand. Take the specimen between the thumb and fore-finger of the left hand, hold the finger horizontally so that its upper surface may form a table, on which the blade of a razor may slide, keep the handle of the razor in a line with the blade, and draw it from heel to tip through the speci- men and towards yourself; keep the blade well wetted with very di- lute spirit, and float olf the sections as they are cut into a saucer of water.

The drug specimen is however frequently too hard for section cut- ting, by hand ; it is then necessary to use a microtome. A very good one is that invented by Mr. Stirling. This is simply a brass well, into which fits a very finely cut screw. The instrument having been

1 Read before the Chemists' Assistants' Association, London, Nov. 22, re- printed from Phar. Jour, and Trans., Dec. 1.

Am'/a0n.yiS9arm'} Drug Sections for Microscopical Examination. 43

firmly fixed to a table by means of another screw, the specimen is im- bedded in a piece of carrot, or a mixture of lard and hard paraffin ; the whole is put into the well, and as the screw is turned and gradually pushes out the whole of the contents of the well, sections are made with a razor or a section knife, which is nothing more than a large razor without a handle.

The knife and specimen should be kept well wetted with dilute spirit, and the sections may be kept until wanted in slightly diluted spirit. It is not necessary to use rectified spirit in section preparing, but the methylated spirit must not contain any kind of gum. A rough and ready test of the fitness of the spirit is to pour it into water ; it should not affect the brilliancy of the water in the slightest degree.

For very friable tissues a special treatment is required. First soak the drug in strong alcohol, then it ether. Now prepare a solution of cel- loidin in equal parts of alcohol and ether, about the thickness of gly- cerin (reserve one-third of this solution). To one-third of this solu- tion add its own bulk of alcohol and ether, in equal parts, and to the remaining one-third add twice its bulk of alcohol and ether in equal parts. Take the tissue out of the ether, and put into the thinnest of the above three solutions, for a few hours, then transfer to the thicker one for three or four hours, and lastly to the thickest for a day ; take out and dry in the air and place in spirit until quite hard and opaque. It can now be easily cut.

The sections will be much more easily examined if they are stained one or more colors, and if they are to be stained they must usually be first bleached. First wash out the spirit by placing in water and then bleach by soaking in liq. sodse chlorinatse, B. P., for from two to ten hours. When all the color has disappeared from the sections wash them in water three or four times at least. They can now be kept in spirit until required. Judson's dyes were at one time used for stain- ing these sections ; but now specially prepared stains are more gener- ally used, which can be bought, or made, if more than a very small quantity is required. For excellent recipes for such stains consult Bower and Vines "Practical Botany."

The spirit should first be washed out of the specimen. It should then be immersed in the staining fluid for from three to ten minutes, and washed in spirit for from ten to fifteen minutes. Lastly, the sec- tion, which now presents a dull appearance, is cleared by placing on

44 Drug Sections for Microscopical Examination. {Am'j£nT/im*Tm'

some clove oil until it sinks (usually in about five minutes) ; it will then be found to be quite clear, and is ready for mounting in Canada balsam, or more conveniently a mixture of Canada balsam and one- fifth its bulk of pure turpentine.

The brightness of a section stained with borax carmine is increased by placing in a mixture of spirit and one-sixth its bulk of hydrochloric acid for a minute or so. The acid must afterwards, of course, be thoroughly washed out.

If a section is overstained it may be remedied by placing in a dilute spirituous solution of hydrochloric acid or dilute aqueous solution of acetic acid according to the stain used.

Double staining is accomplished by using alkaline and acid solutions respectively ; for example, green and red by first plac- ing in an acid green solution, washing with water, and then plac- ing in borax carmine solution, then wash in spirit and clear in clove oil.

Clove oil is a very good clearing medium and a very good vehicle in which to preserve the sections until required for mounting, if it is intended to mount them in Canada balsam. If a specimen is stained before it is sectionized it must, of course, be left in the stain hours, and perhaps days, instead of minutes ; this is only done with soft tissues, such as ovaries, which should be gathered before they are quite ripe. Fresh stems should not be more than three years old as a general rule.

Sections must not be bleached where there are cystolithes or any other cell-contents which the bleaching fluid would dissolve. Certain resinous drugs, such as pellitory, must not be mounted in Canada bal- sam, which would dissolve out the resin ; in such cases glycerin jelly containing carbolic acid, arsenic, or some other preservative, should be used. This is best used, not with a rod, but filtered while hot, and liquid through cotton wool directly on to the slide. To keep glycerin in is a very difficult matter. Gold size, which is at least ten years' old and quite " tacky," or sticky, is a very good cement, but it should be touched over about every five years.

Certain black cements are very liable to run into the Canada balsam and spoil the sections.

In conclusion, I would reaffirm that it is cheaper to make than to buy a good collection of drug sections, especially as many are only ob- tainable on the continent.

PHOTOGRAPHY.

BY F. V. BUTTERFIELD.1

With the exception of a short and succinct historical account, and a few necessary remarks on its relation to light and chemistry, I shall devote the best portion of this paper to the more important details and modus operandi of that branch popularly known as " amateur photography," so that any who are desirous of taking up this fascinating pursuit may be able to do so with, I hope, facility and ease. At the same time, however, others who cannot, for various reasons, take up the practice of photography for pleas- ure, or who rather choose to "scorn delights and live laborious days," will find, I am quite sure, a slight acquaintance with this subject either useful from a business, or interesting from a scientific point of view, for, disre- garded as a work of art, but looking at it solely from a scientific standpoint a photograph may be considered simply as the result of a series of very delicate chemical reactions.

Boasting of barely half a century's existence, photography has made such rapid and gigantic strides that the position it holds to-day is one of the highest importance. Reverting to the details of its discovery we first of all find the old alchemists in the sixteenth century, whilst engaged in their mysterious craft, puzzling over the change they observed took place when silver chloride, or, as they termed it, luna cornua, was exposed to the light, and which, they eventually decided, must be due to a kind of transmutation of metals, a conclusion drawn very possibly, I think, from the philosopher's stone point of view, which when discovered would in some such simple manner " transmute" all the baser metals into gold.

The matter remains in statu quo, until another century " has dragged its slow length along," when history records that this phenomenon attracted the attention of one Robert Boyle the most learned philosopher of his time, and which he finally settled to his own satisfaction must perforce be caused by the action of the air, " sed de mortuis nil nisi bonum." He lived in dark days, when chemistry as a connected science could hardly be said to exist.

The question once more lapses for a long period into a state of quiescence, until at length Scheele, whose name is well known to all of you, appears upon the scene, deeply interested in and trying to solve this very problem, but although he succeeded in proving, by various means, that it was really owing to a reduction of the silver chloride, with partial loss of chlorine, his researches proved of little practical utility at the time.

Years roll on, iodine and bromine have both been discovered and found to give salts of silver much more sensitive to the light than the old chlor- ide; in fact, on all hands we find the enthusiastic army of workers in this scientific research ever increasing and bringing matters gradually to a climax, which at last took place in 1839, a year ever memorable in the annals of photo-

graphy as the period that marks its birth, and when Daguerre, a poor French painter, first exhibited to the gaze of an astonished world the great discov- ery which now bears his name, the daguerreotype, its appearance being warmly welcomed by the vast majority who saw at last a long felt want sup- plied, the very small minority consisting of those who gained a pittance by the art of miniature portrait painting, and to whom it was painfully appa- rent that their occupation had fled. The French government then granted the father of photography and his clever partner, Isidore Niepee, a pension, chiefly on the ground that " The invention did not admit of being secured by patent, since, as soon as published, all might avail themselves of its ad- vantages ; they therefore preferred to enjoy the glory of endowing the world of science and art with one of the most surprising discoveries that honor their native land."

In England, Wedgwood, bearing in mind the experience of Scheele with silver chloride, and assisted by Sir Humphry Davy, had been busily em- ployed in conducting experiments at the Royal Institution with this sub- stance ; but, although he had actually succeeded in obtaining images, no method could, by any possible means, be discovered of " fixing " or making them permanent, so that, when exposed to the light, his pictures gradually faded from view.

Now, there is here real reason for regret, because a year or two later, be- fore the discovery of the daguerreotype had taken place, Sir John Herschel first prepared and demonstrated the properties of hyposulphite, or more properly speaking, thiosulphate of sodium, particularly calling attention to the remarkable solubility of silver chloride in its solution. Here, then, was the very thing for which Davy had longed in vain, and it is now generally supposed that Herschel was ignorant of the results obtained and published a few years previously by Wedgwood and his illustrious assistant, Davy. An- nother circumstance, perhaps still more remarkable, is, that even Daguerre, when he made his great discovery known, was not in possession of any per- fect method of fixing his pictures, and it thus remained for Herschel to once more call attention to his discovery as the only means by which photographs on silver salts could be permanently "fixed."

Herschel, also, first suggested the use of glass plates, and his cyanotypeis, even now, largely used by draughtsmen and others for taking copies of drawings, tracings, etc. In this process one side of a sheet of white paper is brushed over (in the dark or some non-actinic medium), with a solution made by dissolving 1 ounce each of potassium ferricyanide and ferric ammo- nium citrate in 8 ounces of water. When dry it is ready for use, and may then be exposed to a good light, beneath the subject to be copied, and after- wards developed " by simply washing in plain water. During the process of printing the ferric salt is reduced to ferrous by the action of the light (in the presence of organic matter), and this at once combines with the ferri- cyanide present, to form ferrous ferricyanide or Turn bull's blue, which, be- ing insoluble, is not affected by the subsequent washing in water, whilst the unchanged ferric salt is easily washed out, and thus an exact facsimile of the subject, be it negative, drawing or tracing, remains.

In 1841 Fox Talbot patented his famous calotype process. By it he ob- tained invisible images on paper, made sensitive with silver iodide, and de- veloped them by means of a solution of gallic acid. Paper negatives, which at the present time, by reason of their light weight, compactness, etc., are promising to supersede those of glass, are thus by no means "new," another proof that there is nothing new under the sun. There is this difference, however, that the image was in the texture of the paper in Talbot's negatives, whilst now it is on the surface, so to speak.

Bat if photography was not originally given out to the world as the inven- tion of one of perfidious Albion's sons— although at the same time, be it re- marked, historians generally concede to Wedgwood the honor of having been the first photographer we can console ourselves with the fact that, to a worker on this side of the silver streak, Scott Archer to wit, belongs the honor of having introduced the collodion process, as it exists to-day, and in importance his discovery certainly ranks next to that of the daguerreotype. As he had not taken out a patent for his process, and the best thanks of pho- tographers are due to him for this, our Government granted at his prema- ture death a pension to his bereaved family, because he had been 11 the dis- coverer of a scientific process of great value to the nation, and from which the discoverer had reaped little or no benefit."

His collodion process then came extensively into use, as the results ob- tained by it, for studio work in general and portraiture in particular, were vastly superior to those of the daguerreotype. The substitution of glass for metal &s a substratum was also a step in the right direction.

But even here photographers did not by any manner of means rest con- tented, for we find that a grand improvement was soon to take place in the introduction of gelatin as a substitute for the use of collodion, first proposed, after satisfying himself with experiment, by Dr. Maddox, and made practi- cally and commercially successful by Mr. Kennet, of, strange to say, Mad- dox street.

Thus, speaking generally, we have at present three chief photographic processes, the daguerreotype, the collodion, and the one just mentioned, or the gelatin-bromide process.

The daguerreotype is still occasionally preferred for some special kinds of work, and the collodion process has its advantages, particularly in the pro- duction of " positives," but the introduction of the rapid gelatin dry plate, devoid of all the " messiness " of the old wet process, may fairly be said to have called the amateur photographer into existence and made him a striking feature of the nineteenth century.

The daguerreotype consists of a copper plate, which is first coated on one side with a very thin coat of metallic silver by electro deposition and then submitted to the combined action of bromine and iodine, thus forming sil- ver bromo-iodide, a combination which has been proved by experiment to be much more sensitive to light than either of the separate single salts.

After exposure in the camera, the photographic image is developed by means of metallic mercury vapor, usually performed by heating a layer of mercury to about 150° Fahr., and suspending the plate over it, in the dark,

48

or some non-actinic medium, of course, then finally fixed by a solution of thiosulphate of sodium.

Now, as regards the chemistry of this process, the first question that nat- urally presents itself is, What important change does the light produce on the sensitive surface of silver haloid salts when exposed to its influence f You will at once remember that this is the very problem Scheele tried so hard to solve, and to-day, although a century after, we have not yet arrived at a clear solution. This is possibly little matter for surprise when we con- sider that, to begin with, we do not know what light itself really is. Some theorists even argue that the light does not produce any chemical decom- position whatever, but merely a physical change. The accepted theory, however, appears to be, and it receives the support of our best authority Captain Abney that a subsalt is formed thus :

Ag2I2+ligbt=Ag2I+I, the free iodine combining with excess of silver present to form more silver iodide.

But then, on the other hand, no one has ever yet prepared a definite chemical compound of silver with any of the halogens, containing less of the latter than the ordinary chloride, bromide or iodide, and so the matter remains.

Accepting the subsalt theory, then, the development of the latent or pho- tographic image is apparently due to the attraction of the sub-iodide for the mercury-vapor, the resulting visible image consisting of a white amalgam of mercury and silver, whilst in the process of " fixing " the thiosulphate sim- ply dissolves away the unaltered iodide by forming a soluble double salt thus :

2AgI+3Na2S203=Ag2Na4(S203)3+2NaI. Turning to the collodion process we find glass plates are used, coated on one side with collodion, containing in its solution a bromide and iodide, usually ammonium iodide and cadmium bromide, and as soon as it is"set," they are sensitized by immersion in a bath of silver nitrate, when double de- composition of course takes place in the film, silver bromide and iodide be- ing formed. Whilst still in this moist state, they are exposed in the camera and, after exposure, a solution of ferrous sulphate, with the addition of a little acetic acid and alcohol, is used for their development ; the reactions that take place whilst developing being oxidation of the ferrous salt to the ferric, and consequent reduction of the silver salts to the metallic state, the latter remaining insoluble in the film, and constituting the image, the acid contained in the developing solution merely acting as a restrainer to pre- vent the too rapid reduction of the silver salt, whilst the alcohol simply ex- ercises a mechanical action in causing the solution to flow more evenly over the plate.

The reaction would, I think, be expressed by the following equation : 6Ag2Br+6FeS04=Fe2Br6+2(Fe23S04)+12Ag. After washing they are then "fixed "by means of a solution of " hype," which, as before, merely dissolves out the unaltered iodide and bromide of silver.

AmjJa°nuyiS8arm'} Minutes of the Pharmaceutical Meeting. 49 MINUTES OF THE PHAKMACEUTICAL MEETING.

Philadelphia, December 18, 1888.

The meeting was called to order and Mr. Wm. Mclntyre was asked to preside. The minutes of the last meeting were read and approved.

Professor Trimble stated that at the last meeting of the College Committee upon revision of the pharmacopoeia the question of the strength of bleaching powder was discussed, and it was thought by some that the statement of our standard was much lower than the character of the chlorinated lime of com- merce warranted. Mr. H. J. M. Schroeter, a post graduate of our School, at Professor Trimble's suggestion, made a number of determinations of the amount of chlorine in various lots he had obtained from various stores, and found an average would be rather over twenty-nine per cent ; he read a paper giving the results of his assays.

Professor Maisch stated that while this subject was under consideration in the Eevisional Committee it was well known that much stronger chlorin- ated lime could be obtained in large quantities ; but it was thought best to adopt a minimum percentage of 25 because the substance was quite liable to lose chlorine and such a grade could be readily secured by the pharma- cist. Prof. Maisch inquired if that contained in small packages was uni- form in strength and as strong as that taken from the large casks ; the arti- cle imported in the casks was very well preserved.

Mr. Meyer asked if the sales of chloride of lime were not less than form- erly. He was of the opinion that it was ; but several thought that the sales were more frequent. It was stated that all chorinated lime consumed here was of foreign manufacture as the black oxide of manganese of American origin is inferior to that which is imported. A query was put whether the manganese ores were contaminated with cobalt ; to this answer was made that they were rarely found together.

Mr. England read a paper upon a permanent syrup of hydriodic acid. Professor Maisch asked Mr. England if he had tested the pharmacopoeial syrup for glucose; he said that he had not done so. Mr. Beringer said he had made syrup of hydriodic acid by the double decomposition of potassium iodide and crystallized tartaric acid, but that he had added some sugar to the solution of potassium iodide to prevent change, and he found the syrup had kept well since August, 1887.

Professor Trimble reminded the meeting that last month he read a paper upon a berry used as food. At this meeting he would call attention to a root, which was largely used for nutrient purposes, obtained from Lewisia rediviva. It was generally stripped of its bark and contained a large amount of mucilage.

Mr. Mclntyre remarked that as some of the members were going to cross the Kocky mountains for the next meeting of the American Pharmaceutical Association, they should bear this root in mind; if they should run short of provisions and had to forage it would be a novel experience.

Mr. England inquired about the loco-weed of the Western States ; some parties had stated that it was particularly poisonous to cattle, while others

thought such was not the case. Prof. Maisch stated that the experiments upon the subject made by preparing infusions, tinctures and extracts failed to show any specially poisonous properties, and Professor Sayre had been unable to find in the plant any deleterious principle ; but the physiological experiments had been made upon carnivorous and omnivorous and not with herbivorous animals. The American loco weeds were species of the genera astragalus and oxytropis, and were botanically closely rlated to the shrubs of Western Asia yielding tragacanth.

Mr. G. M. Beringer read a paper upon the Hungarian Daisy, an im- portation of which had been made into New York, and which was likely to be used as an adulteration of the insect powder. Prof. Maisch sug- gested that since the microscope seemed to afford no reliable criterion for the detection of such an adulteration in insect powder, the percentage of alcoholic extract and of ash, as determined by Mr. Beringer, might be made available for this purpose.

The papers read, having been referred to the Committee on Publication, there being no further business, the meeting adjourned.

number of gentlemen well known to the pharmacists of the country, who as " collaborators " will hereafter identify themselves with the Journal even more closely than in the past.

In closing the eighteenth year as occupant of the editorial chair and the thirty-fifth year as one of the contributors to the pages of the Journal, the Editor desires to thank his many friends for their uniform courtesy in the past, and with his best wishes towards all at the beginning of the present year, to request a continuance of their favorable interest in the Journal.

T he next meeting of the American Pharmaceutical Association.— We are in- formed by the chairman of the Committee on Arrangements, Prof. Emlen Painter, New York, that the Committee has not made, or authorized the pub- « lication of any statement concerning arrangements for the trip to California. The date of the meeting has not yet been fixed, but will probably be either June 24th or July 15th, and members are requested to communicate their preference to the chairman without delay. It is contemplated to give a through rate at the least possible expense, and to make the side excursions entirely optional. The announcement of the date and of the plan for the trip to California will be communicated, over the signatures of the Commit- tee, in time for publication in the February issues of the Pharmaceutical Journals.

The Manufacture of Fuid Extracts by Retail Pharmacists is the theme upon which essays have been invited by the Anderson Manufacturing Company, Detroit, Michigan. The essays are not to exceed in length 1000 words, and are to be sent by March 1st next to P. O. box 134, Detroit. It is expected that the professional as well as the financial advantage of such manufactur- ing be discussed, and that as much as possible the results obtained in actual work be given, and not mere theorizing or excerpts from the work of others. A committee of three pharmacists will decide upon the merits of the essays received, and award the two prizes, consisting of percolation apparatus.

Rewards for meritorious discoveries and inventions. The Franklin Institute of the State of Pennsylvania, through its Committee on Science and the Arts, is empowered to award, or to recommend the award of, the following medals :

1. The Elliott Cresson Medal (gold), founded by legacy of Elliott Cres- son, will be granted for the invention or improvement of some useful ma- chine, or for some new process, or combination of materials in manufactures, or for ingenuity, skill or perfection in workmanship.

Second Annual Report of the State Board of Health and Vital Statistics of the Commonwealth of Pennsylvania. Transmitted to the Governor Decem- ber 1, 1886. Harrisburg. 8vo. pp. 1056.

The publication of the first annual report of this Board was noticed on page 622 of our volume for 1886. The publication of the volume now before us was delayed in consequence of the printing of the reports of other departments having been previously authorized by the Legislature and therefore, taken precedence.

The report of the Secretary, Dr. Benj. Lee, and the minutes of the Board occupy only a small portion of this stately volume. By far the greater portion is taken up by special reports, essays, statistics, etc., all of which appear to have been prepared with much care. Thus we find reports on water supplies and drainage of different localities ; on local epidemics and special sources of disease ; on quarantine and disinfection ; mortuary tables ; various legal proceedings ; an account of the State Sanitary Convention, with the papers read before that body ; the proceedings of the National Conference of State Boards, etc.

The care bestowed upon the preparation of this volume reflects credit upon the Board and its secretary, and it is to be hoped that in the future the Legislature may, more promptly than heretofore, take action for the early publication of such reports.

GOLD CHLORIDE AND SILVEE NITRATE AS TESTS FOR FIXED OILS.

By Frank X. Mcerk, Ph. G.

A Contribution from the Chemical Laboratory of the Philadelphia College of

Pharmacy.

Read at the Pharmaceutical Meeting, January 15th.

In the Pharm. Ztschr. f. Russl, 1888, 721 (Am. Journ. Pharm., 1889, 23), E. Hirschsohn gives as a reliable and easily applied test for the detection of cotton-seed oil the behavior of this oil towards a chloroformic solution of gold chloride (1 gm. to 200 cc), and asserts that it will indicate one per cent in admixture with olive oil. The procedure is to take 5 cc. of the oil with 10 drops of the gold chloride solution and heat for twenty minutes by placing the test tube in a vessel containing boiling water, a red color indicating the presence of cotton-seed oil. With a view of confirming this apparently valuable test numerous samples of commercial oils were obtained, on which, however, little reliance for purity could be placed ; from Mr. Geo. M. Behringer were received samples which he believed to be pure, based upon confidence placed in the producer as well as upon tests made with the samples ; other samples were gotten in the chemical laboratory by means of solvents.

Before giving the results in detail it may be well to state that the test which Hirschsohn claims as so characteristic for cotton-seed oil was also obtained with the oils of arachis, ben, poppy (an imported oil), sesame and walnut kernel. To ascertain if these oils were con- taminated with cotton-seed oil, or probably contained a common prin- ciple, their effect upon silver nitrate solution was tried, using the method of O. Hehner (Analyst, September, 1888, and Am. Jotjrn.

Gold Chloride and Silver Nitrate as Tests.

f Am. Jour. Pharm. X Feb., 1889.

Pharmacy, 1888, 575), 1 gm. silver nitrate, 200 cc. alcohol, 40 cc. ether, O'l gm. nitric acid ; the oil with half its volume of this solution was kept in a water-bath at 100° for fifteen minutes, noticing the effect produced in this time. It was found that some fixed oils which could not be identified at the end of this time could be distinguished by heating for one hour in the same way, noticing the effect, and then cooling by placing in a vessel of cold water. The prolonged heating had, in addition to the color imparted, the effect of rendering most of the oils more viscid, while some of them became almost, others quite solid. The oils giving the red color with gold chloride behaved differeutlywith silver nitrate, indicating that they were not identical.

For comparison the oils examined are divided into three groups : 1, pure oils ; 2, commercial oils corresponding to those of group 1 ; 3, commercial oils of which no reliable specimens were examined, and hence cannot be commented upon.

In giving the results of the reagents with Au Cl3, the time of ob- servation was twenty minutes, if a color appeared sooner, the time is given ; with silver nitrate, a indicates the effect in fifteen minutes, b in one hour.

It will be seen that most of the oils give dark colorations or pre- cipitates with silver nitrate, so that this test can not be used to indicate

positively the presence of cotton-seed oil ; there is, however, with cotton-seed oil always a grayish film separated on the sides of the test tube, with mustard and rape oils a film is formed which is of a black color, the color being due possibly in the first case to metallic silver, in the second case to sulphide of silver.

Arachis oil with silver nitrate develops in a few minutes a red color which then passes into a dark brown in the course of fifteen minutes ; this test is apparently characteristic for arachis oil among the vegetable oils but is also given by some of the fish oils.

Cotton-seed oils may differ in the rapidity with which they react with both Au Cl3 and Ag NOs, this no doubt being due to the manner and completeness of the purification of the oil by chemicals ; there is also a difference in their behavior to sulphuric acid. To ascertain something of the nature of the body giving the reaction with Au Cl3, a portion of cotton-seed oil was mixed with alcohol and some pieces of potassium hydrate ; after shaking a few minutes a clear solution was obtained which was poured off from the undissolved potassium hydrate into a large volume of water ; by this means the unsaponified oil was again separated, the soap remaining in solution ; the separated oil was now saponified and from the two soap solutions were precipitated the fatty acids. The acid obtained from the easily saponified portion of the oil contained a liquid and a solid portion which could be separated by cooling the mixture ; with Au Cl3 a very fine red coloration was produced ; the acid from the more difficultly saponified portion of the oil was solid and gave only a momentary red color, changing into a violet and depositing a dark precipitate. The cause of the red color is hence to be found in the liquid acid.

Attention should be called to the difference between the poppy-seed oils ; No. 1 is an imported oil, Nos. 2 and 3 were made from black poppy-seed by expression. The difference is so great that the oils were possibly made from different kinds of seed, the imported probably from white poppy-seeds.

Regarding these oils, some show adulteration : Almond, 1 with arachis oil ; almond, 2 with peach-kernel oil ; olive 1, the adulterant possibly a mixture ; olive 3, with cotton-seed oil ; salad, a mixture of arachis and sesame oils.

Finally a few mixtures of olive and cotton-seed oils were made containing one, five and ten per cent, of the latter oil and subjected to the gold chloride test; the ten per cent, mixture gave on warming for 12 minutes a red color, very distinctly ; the five per cent, mixture did not react in twenty minutes but if heated for one-half hour slowly deposited a precipitate of metallic gold ; the one per cent, mixture showed no color whatever with gold chloride but with silver nitrate gave a slight deposit on the sides of the test tube. The separation of metallic gold by a number of the oils is probably traceable to the amount of reducing acid present being insufficient to give the red color.

Aqua cnloroformi has not only antiseptic and anaesthetic properties (Am. Jour. Phar., 1888, pp. 408, 475), but according to Ullrich (Prag. Med. Wochenschr., 1888, JSTo. 33), is also an effective haemostatic, very useful in bleeding from the gums after the extraction of teeth.

Chamomile Flowers. On exhausting the flower heads of Anthemis nobilis with petroleum benzin, Ella Amerraan, Ph. G., obtained a green wax, which after six recrystallizations from alcohol was nearly white, bitter and crystalline, and melted at about 130° C. On ex- hausting the drug now with ether, and treating this extract again with ether, as recommended by Camboulises in 1871, a crystalline sub- stance, distinctly acid, and of a glucosidal nature was obtained. A small quantity of similar crystals was also obtained by Werner's pro- cess (1867) by exhausting with dilute acetic acid, concentrating, pre- cipitating with alcohol, treating with chloroform, evaporating, ex- hausting with ether and treating this extract with warm distilled water. In a third experiment the alcoholic tincture of the flowers was concentrated, precipitated by water, the filtrate treated with chloroform, the solvent evaporated and the residue treated with water. The aqueous solution of the crystals, on being boiled with hydrochloric acid, became opalescent, emitted a honey-like odor, and with Fehling's solution now gave evidence of the presence of glucose. There was no evidence of the presence of an alka- loid.

Diospyros virginiana, Lin. The bark of this tree is of a tan color, and has a mucilaginous bitterish, then swreetish and astringent taste. Experiments made by Frank E. Murphy, Ph. G., gave the following results : The powdered bark yielded to petroleum benzin 0'9 per cent, of an amber colored extract, free from volatile oil. Ether took up 1*4 per cent., the extract yielding to alcohol a wine colored mass, which deposited from chloroform in stellate or granular crystals. The alcohol extract of the bark amounted to 2*5 per cent, and was partly soluble in water. The water extract weighed 12 per cent, and con- tained mucilage and dextrin. The extracts thus far obtained yielded a purple color with alkalies, the reaction being due to yellow coloring matter. On treating the exhausted bark with weak solution of soda, the mixture also acquired a deep purple color, and ultimately became gelatinous. The acid infusion of the residuary bark gave with ammonia a purple colored precipitate ; calcium oxalate was not found.

A quantity of the partially ripe fruit was dried and treated with

ether ; on evaporating the solvent a granular extract was left, which became purple by alkalies from the presence of yellow coloring mat- ter.

Eriodictyon calif or nicum, Bentham. An analysis of the leaves yielded to Oliver F. Lenhardt, Ph. G., 7*6 per cent, of moisture, and 4*25 per cent, (or for the anhydrous drug 5'14 per cent.) of ash. Of the latter 26 '66 per cent, was soluble in water, 63*4 per cent, soluble in HC1, and 3'5 per cent, soluble in solution of KHO. Petroleum benzin extracted, including volatile oil, 2'63 per cent., of which '39 was wax which separated from hot alcohol amorphous and melted at 61 °C. With ether 15*3 per cent, of extract was obtained, of which three-fifths (9 per cent.) was a brittle, fragrant, and slightly acid resin soluble in 80 per cent, alcohol ; a little tannin was also present, and the green tenacious residue was partly soluble in benzol, and entirely soluble in carbon disulphide, and in chloroform ; alkaloids and gluco- sides were absent. The exhausted leaves yielded to absolute alcohol 3*64 per cent, of extract, fully one-third of which was soluble in water, among other constituents tannin and a glucosidal compound being dis- solved. The watery extract of the exhausted leaves weighed 22 '3 per cent,, was of a brown color, had a pleasantly sweetish and somewhat acrid taste, and contained tannin.

Lycopus virginicus, Lin. Sherman F. Hennessy, Ph. G., ex- perimented with air dry bugle weed, containing 9 per cent, of mois- ture. Cold water dissolved 10*4 per cent, of constituents, consisting of albuminoids, gummy matter, a little tannin, and extractive. Alco- hol now took up 12*8 per cent, of chlorophyll, resin, bitter extractive, etc. A small quantity of a lemon-yellow volatile oil was obtained by distilling the herb with water.

Stigmata Maydis. John Rea, Ph. G., determined in the cold water infusion of corn silk (fresh ?) the sugar by means of Fehling's solution, which indicated 0.88 per cent. ; after boiling the infusion for one hour with hydrochloric acid, 1*42 per cent, of sugar was found.

Commercial Kino. Chas. H. Breidenbach, Ph. G., examined five samples of Malabar kino and four samples of poAvdered kino, of which F and G were odorless and had a red-brown color, while H and I had a slight aromatic odor and a very dark-red grayish-brown color, and yielded a gray-brown ash, that of the other samples being white. The results are as follows :

The ether soluble portion dissolved readily in alcohol, and this solu- tion gave, with ferric chloride, a deep-green color. The portions in- soluble in absolute alcohol yielded from 65 to 92 per cent, to water, except for H and I, which residues were completely insoluble in wa- ter. Of the same two samples the residues left by water treatment yielded to alcohol 98 per cent., while the corresponding residues of the remaining seven samples contained between 77 and 90 per cent, of alcohol soluble matter.

A quantity of gelatinized matter from old tincture of kino was procured and proved to be insoluble in acids, alkalies, alcohol, ether and water ; but was not further examined since the kino which had yielded it could not be obtained.

Tincture of kino was made from some of the above samples the menstruum used being 1, the officinal one ; 2, alcohol 85, glycerin 15; 3, dilute alcohol ; 4, water 75, alcohol 25 ; 5, absolute alcohol, and 6, 95 per cent, alcohol. The best results were obtained with menstruums 4 and 5, the tinctures with 5 being practically free from precipitates ; those with 4 containing a distinct precipitate, and the remainder show- ing, after a month or two, indications of gelatinizing. Tincture of kino yields with lead acetate a dark bluish precipitate ; the same reagent gives with tincture of catechu a light yellow, and with tincture of kino containing 10 per cent, of catechu, a dingy gray green precipitate.

Pills of Tliymol are conveniently made by using soap as an excipient, and are prepared by Dr. Frederic-Henry (Jour, de Med.) in the treatment of various intestinal disorders. The thymol is given in doses of 0*12 to 0*15 gm . every six hours.

Soluble Gum of Tragacanth.

ON THE SOLUBLE GUM OF TRAGACANTH.

By John M. Maisch. Read at the Pharmaceutical Meeting, January 15.

From an attentive student at a College of Pharmacy a letter was recently received as follows :

" While comparing your " Manual of Organic Materia Medica " with the United States Pharmacopoeia I find a point where your book diifers from the latter. You state that the fluid portion of the gela- tinous mass, obtained by treating tragacanth with water, is precipi- tated by alcohol, while the Pharmacopoeia says, this is not so. Is this statement of the Pharmacopoeia correct ? "

My attention having thus again been called to this statement of the Pharmacopoeia, it was determined to repeat an experiment frequently made in former years. Some thin flakes of white tragacanth were washed with cold water, and then soaked in sufficient water without applying heat ; cold water was then added from time to time with agi- tation, until the gelatinous mass remained sufficiently thin after stand- ing for some time to permit the fluid portion to be separated by means of a wetted filter. On pouring some alcohol upon the clear filtrate, both layers remained clear also at the point of contact, and on mixing the two liquids, the transparency of the mixture was apparently not disturbed immediately ; but on close examination the formation of a transparent jelly could easily be distinguished, and this separated after a while in the form of whitish flocks rising to the surface. The re- sult corroborates that of experiments previously placed on record by others, and proves that a portion of tragacanth is soluble in cold water, and that this solution is precipitated by alcohol. In performing this ex- periment, it is necessary to avoid the use of heat, since tragacanth al- ways contains starch which would be dissolved by hot water.

It seemed of interest to ascertain, if possible, how the error alluded to crept into the United States Pharmacopoeia. Very probably it was copied from the British Pharmacopoeia of 1867, as will be seen by comparing the texts of the two authorities :

found also its way into the present British Pharmacopoeia, published in 1885, the statement differing from the above quotation mainly in describing the color produced by iodine to be violet or blue.

It was to be expected that the statements of recent English and American writers on Materia Medica and on Chemistry would differ in regard to the question involved, and that some of them would have adopted, without reserve, the characterization of tragacanth as given by the two pharmacopoeias, while others would give it as ascertained by experiment or from the writings of others. Such has indeed been found to be the case as will be seen from the following brief summary.

Regarding merely the effect of water upon tracaganth, the latter is described by Bloxam, Edes, Fownes and Wood, as being not soluble, but merely swelling in water. The property of swelling with water to a gelatinous mass is, as a matter of course, mentioned by all writers ; but in addition to this tragacanth is described to be sparingly or very sparingly soluble in water by Allen, Brunton, and Milne, (edit, by Craig). These writers do not allude to the effect of alcohol upon the soluble portion.

In several works the correct statement is made that tragacanth is insoluble in alcohol ; but this property does not throw any light upon the behavior of the aqueous solution, since some of the vegetable mucilages are insoluble in alcohol when treated directly with this liquid, while their aqueous solutions are not disturbed on the addition of alcohol.

A nearer approach to the behavior of the water-soluble portion of traga- canth is found in Attfield, Biddle, and in Bentley and Trimen's Medicinal Plants, where that portion is said to resemble arabin, but the points of resemblance or difference are not given. Potter and Prescott (proxi- mate analysis) state the soluble gum to be arabin.

The language of the British Pharmacopoeia is quoted in the works on Materia Medica by Bentley, Bruce, Gerrard and Thorowgood, the last two stating that the alcohol test (non-precipitation of the aqueous solution) shows the absence of gum arabic.

The correct behavior towards alcohol is given in Pharmacographia and in the manuals of Muter, Royle (edited by Harley) and Wills.

About half a century ago Pereira, in his Materia Medica, gave the following account, which was reproduced in the later editions : " The soluble gum of tragacanth is usually regarded as similar to gum arabic, and hence it is called arabin ; but is distinguished by silicate of potash and perchloride of iron producing no change in it,

and by a peculiar appearance of the precipitate produced with alcohol (the precipitate is flocculent and collects in a simple opaque and mucous mass). In common with arabin it produces precipitates with diacetate of lead, protochloride of tin and protonitrate of mercury. Oxalate of Ammonia detects in it a calcareous salt."

Gmelin's Chemistry (Cavendish edition, XV., 209) states : " Traga- canth jelly curdles a solution of bichloride of tin ; according to Bostock it forms a reddish precipitate with mercurous nitrate; according to Pfaff a white precipitate with both mercurous and mercuric nitrate. It is precipitated by alcohol.

The use of the word not in the sentences quoted above from the Pharmacopoeias was probably at first an inadvertent error, as suggested by Oldberg and WahPs " Companion ; " but since such errors are likely to be perpetuated in print, it was deemed advisable to again call attention to it at the present time.

ON FILTERS.

By Edo Claassen.

It is well known, that analytical work always requires filtering paper of very good quality ; in many cases even the best kind obtain- able is necessary. The expenses caused by the high price of such paper are not inconsiderable. On account of this fact and with the purpose, probably, to reduce the cost of filters, Rother recommended the use of pieces of paper, exactly half as large as those usually taken for filters. His filters have a somewhat unsymmetrical shape, unless they are trimmed at last by cutting off the useless and objectionable part. By this operation, however, some paper is wasted, which is entirely prevented, if the filters are made according to the following di- rections: Patterns (corresponding with the size of the filters wanted, for instance with such, having a radius [semi-diameter] of 12 J, 17 J, 22 J, 27 J, 32J, 371 421 50, 60, 80, and .100 centimeters) are constructed from circular discs of tinned sheet-iron of the same size by cutting off somewhat more than one half the disc (see fig. 1.) through a point distant from the edge 15, or respectively 21, 27, 33, 39, 45, 51, 60, 72, 96 or 120 centimeters. The small section of the disc, if of no use for smaller patterns, may be rejected. Such a pattern is placed on a sheet of paper, a piece of which is then cut off by allowing the scissors to go around on the edge of the tinned iron. This piece is now folded once in such a manner that one part entirely covers the other (fig. 2).

It is then folded so far on the straight open side, that both the straight sides now present are of equal length (fig. 3). The narrow folded part (2j- centimeters wide, if a filter of the smallest size above mentioned is to be made) is folded once more, after which operation the filter is ready for use. If the funnel on hand should happen to have a larger angle (be wider) than 60°, the filter may be easily adjusted by folding the narrow part in the direction from a to b (fig. 4) ; if, however, the angle of the funnel should be smaller than 60°, the filter may be made

to fit by folding the closed side in an oblique direction as shown (fig. 5). By making filters in this way, two-fifths of the paper necessary for ordinary filters are saved ; but three sheets are used instead of five, a matter of importance and therefore to be taken notice of.

It is obvious that this kind of filters will suit also for pharmaceuti- cal work in all cases, which allow or require the use of a plain filter. It, furthermore, may be taken into consideration, that, no doubt, fil- tration will go on much quicker by means of such a filter than by an ordinary plain filter, it offering a simple layer only of paper to the liquid to be filtered.

MODIFIED FORMULA FOR BROWN MIXTURE.

By J. H. Buckingham, Ph. G. Read at the Pharmaceutical Meeting, January 15th.

It has always seemed strange that, in this " Age of Elegant Pharm- acy," no special attention has been paid to the improvement of such a valuable preparation as the Mistura Glycyrrhizse Composita. The last Pharmacopoeia made a step in that direction, bythe substitution of the purified extract of glycyrrhiza, but still the sediment in part remains. After several experiments I beg leave to suggest to the committee on the revision of the Pharmacopoeia, the following formula. The fin- ished preparation, a sample of wnich I send, is elegant in appearance,

palatable in taste, contains no sediment, and is made of the ingredients in the proportion according to the Pharmacopoeia.

The mixture of glycyrrhiza, sugar and gum arabic is tied up in a bag. Having mixed the other ingredients, with the exception of the ammonia water, I place them in a wide-mouth bottle and suspend the bag in the liquids. In two days the liquid will dissolve the solids and then I add the ammonia and make the whole measure -one pint by the addition of water. All the physicians, to whom I have shown the preparation, are very much pleased ; and recommend it, as superior to any " Brown Mixture " they have seen.

GLEANINGS FROM THE GERMAN JOURNALS.

By Frank X. Mosrk, Ph. G.

Thiol is a new remedy proposed by Dr. Jacobsen as a substitute for ichthyol; it is made by heating the distillate from peat-tar to 215° with 12 to 15 per cent, sulphur ; by treating this product with strong sulphuric acid the sulpho-acid is produced which, after purification, is neutralized with ammonia forming ammonium sulpho-thiolicum, or simply called thiol. It is soluble in water and in a mixture of alco- hol and ether, but not so soluble in either solvent singly. The sodium salt is analogous with the above and contains 12*1 per cent, sulphur. They have the same remedial value as ichthyol. Apoth. Ztg., 1888, 1056.

Ichthyol Pills are recommended by Deni to be coated with balsam of tolu to mask the odor. {Pharm. WeckbL), Pharm. Ztg., 1889, 7.

Ink and Rust Stains are removed easily by a solution containing ten parts each of tartaric acid, alum and distilled water. The solution has the trade name " encrivoir." Pharm. Ztg., 1889, 7.

verted into iodoform ; the excess of iodine is present as iodide and hypoiodite of potassium which react, on acidifying with hydrochloric acid, with each other to liberate iodine which is then titrated with standard sodium hyposulphite. Every 759*6 parts iodine used repre- sent 58 parts acetone. J. Messinger, Ber. d. D. Chem. Ges., 1888, 3366.

Ash Determinations. G. Kassner recommends the addition of an equal weight of finely divided metallic silver to such organic sub- stances as are difficultly incinerated. The use is based upon silver absorbing oxygen at higher temperatures which is then readily yielded to the carbonaceous matter. F. Stolba has obtained complete incin- eration, in J to f hours, of substances which, without this addition, required six hours. Ferric oxide can be used in the same way, but the ash is not so easily examined. Platinic chloride and spongy pla- tinum have been used with the same result as with metallic silver. Pharm. Ztg., 1888, 766, 781.

Manganese oxalate, if added to oils in quantity varying from 2 to 5 per cent., had decided advantages over other mauganese or lead com- pounds in the manufacture of drying oils ; the oils become markedly drying, and remain almost white. Manganese oxalate is decomposed by heat into manganous oxide, which remains in the oil, and carbon monoxide and dioxide liberated as gases. J. Casthelaz (Bull. Soc. Chem.), Chem. Ept, 1888, 346.

Nitrobenzol, if present with oil of bitter almond, can be detected by the following method : Warm with a little sodium hydrate and add ferrous sulphate to destroy odor of hydrocyanic acid ; an addition of considerable excess of potassium permanganate will now remove the odor of oil of bitter almond by oxidizing this compound to benzoic acid, while the treatment does not affect the nitrobenzol, which now can be easily detected by its odor. Dr. K. List, Chemiker Ztg., 1888, 1727.

Antifebrin in Phenacetin, if present to extent of five per cent, or more, can be readily identified by making a saturated aqueous solu- tion, and adding to this half a volume of bromine water. Antife- brin decolorizes the bromine water immediately, and in a few moments a crystalline precipitate appears. Phenacetin neither decolorizes the bromine water nor gives the precipitate, which is supposed to be acet parabromanilide, and is almost insoluble in water. E. Hirschsohn, Pharm. Ztschr.f.

For hospital use, instead of a concentrated alcoholic solution, they recommend : Corrosive sublimate 50 ; sodium chloride 5 ; distilled water 45.— Pharm. Ztg., 1888, 739.

Sodium hydrate containing nitrate is a common article of commerce, the origin of the nitrate being the demand for a pure white sodium hydrate, to obtain which from 2 °f0 to 3 % nitrate are added by the manufacturer. This impurity is especially objectionable in nitrogen determinations using KjeldahPs method by making the results too high. Dr. Schweissinger, Pharm. Centralhalle, 1888, 587.

Syrupus Ferri Iodidi has been studied by Zelinka relative to its de- composition ; the conclusions arrived at are that if a pure distilled water, free from chlorine, ammonia, carbon dioxide and other volatile impurities, obtained by rejecting the distillate until this gives no re- action with silver nitrate, be used in the preparation of the syrup a product will result that can be kept in larger quantites for a long time.— Pharm. Post, 1888, 794.

Volumetric estimation of glucose. In the usual method by precip- itation with Fehling's solution, the cuprous oxide renders the end re- action indistinct to prevent which H. Causse recommends the addition of ferro-cyanide of potassium to the reagent which will dissolve the precipitated cuprous oxide and which itself exerts no reducing action on Fehling's solution. To carry out the operation 10 cc. Fehling's solution are mixed with 4 cc. solution of ferrocyanide of potassium (1:2), heated to the boiling point and the sugar solution added, drop by drop, until the solution becomes colorless. (Bull. Soe. Chim.) Chem. Ept., 1888, 338.

Volatile Alkaloid in Ipecacuanha. E. M. Arndt in distilling a mixture of powdered ipecac, potassium carbonate, ferric chloride and water, noticed in the condenser white crystals while the distillate had an alkaline reaction and was fluorescent ; the alkaloid was obtained

AmFeb*\m&vm'} Abstracts from the French Journals. 79

in colorless cross-like crystals fluorescent at the edges and deliques- cent. The hydrochlorate crystallizes best in octahedral form, and can be obtained in quantity from 0*3 to 0*5 per cent. The nitrate does not crystallize even when attempted over H2S04, resembling ni- trate of emetine. PtCl4HgI22KI, Nessler's reagent, and iodine solu- tion yield precipitates ; Na OH on boiling, evolves the odor of trimethy- lamine. The yield of emetine by the ferric chloride and potassium carbonate method of estimation is greater than by other methods, hence this precludes the decomposition of emetine. Apoth Ztg., 1888, 1036.

Oxygen can be prepared handily by the action of hydrogen dioxide upon potassium permanganate ; 100 cc. of the commercial hydrogen dioxide, 3 per cent, will yield about one liter oxygen. A generating flask is half filled with the H202, made alkaline by a few drops of NH4OH, and K2Mn208, is slowly added through the funnel-tube (5cc. of a 0.3 per cent, solution), when the reaction ceases more of the K2Mn208 is added. All of the available oxygen has been obtained if the liquid in the flask retains a red color on acidifying with sulphuric acid.— C. F. Gbhring, Chem. Ztg., 1888.

W. Lindner recommends the use of an acid solution of H202. Chem. Ztg., 1888, 1696.

ABSTRACTS FROM THE FRENCH JOURNALS.

Translated for the American Journal of Pharmacy.

Inalterable Iodide of Potassium Ointment. A writer in the Gior. Farm. Trent, gives the following : Iodide of potassium, white Venice soap, distilled water, of each, 100 ; glycerin, 600 ; fresh, or benzoinated lard, 300. Dissolve the iodine in the water (using a water- bath), and then the soap; add the glycerin, and afterward the lard. As soon as the lard has melted stir rapidly and continually, and stand the dish in cold water. Repert. de Phar., Nov. 1888.

Glycerin Suppositories. The following formulae, presented by Nouv. Rem., Dec. 24, are brought together from German sources; 1.

Cacao butter, 2*50 gin. to 5 gm. ; glycerin, 1 gut. to 2 gm. ; gum tragacanth, 2 cgm. to 4 cgm. 2. Glycerin, 90 parts ; medicinal soap and mutton suet, of each 5 parts. Dissolve the soap in the glycerin and add the suet ; melt and stir ; pour into molds and let stand in a cold place for 24 hours. See also Am. Jour. Phar., 1§88, p. 560.

Lanolin in Suppositories.— According to M. L. Broutin, Bull. Com., Nov., 1888, lanolin greatly facilitates the introduction into suppo- sitories, of extracts or other substances soluble in water. He thinks that when the choice of an excipient is left to the pharmacist, he may properly replace a small quantity of the cacao butter with lanolin. The following formula is cited as having given excellent results : Dry extract of hamamelis, 1*75 gm. ; lanolin, 9 gm. ; cacao butter, 90 gm. ; for 25 suppositories. The extract is heated with a sufficient quantity of water, to which the melted butter is added by degrees. The mass should be run on as soon as it commences to thicken. The suppo- sitories are entirely homogenous.

Injection Brou. The Jour, de Phar. et de Chim., Jan. 1, gives the formula as follows : Make an infusion with : Crude opium, 50 cgm. ; catechu, 50 cgm. ; saffron, 1 gm. ; boiling water, 200 gm. Filter, and add : Acetate of lead, 1*50 gm. ; sulphate of zinc, 3 gm.

Ratafia of Cacao. Dr. L. Jeannel having made this prepara- tion in accordance with Guibourt's formula, as given in FOfficine, ob- tained unsatisfactory results. After trying several combinations he has arrived at the following, which he recommends : Cacao (bruised and torrefied), 750 gm. ; sliced vanilla 2 gm. ; alcohol of 56 per cent. 4000. Macerate for 15 days ; strain ; add to the residuum, boiling distilled water, 1,100. Leave to cool ; add to the infusion, crushed sugar, 1300. Dissolve, mix with the alcoholic liquor, and filter. Bull. Com., Dec. 1888.

Arrack or Yaraque.— In a communication to the AcadSmie des Sciences, M. V. Marcano states that the natives of upper Orinoco make arrack from the root of Manihot utilissima or cassava. It is dampened, covered with banana leaves and allowed to stand for sev- eral days. The substance is then bruised and placed in a cylinder woven with banana leaves and having an opening at the bottom. From this aperture a thick, syrupy liquid runs slowly and is col- lected. The day before arrack is wanted, a bitter aromatic infusion is introduced at the top of the cylinder. The resultant liquor fer- ments very energetically and gives an intoxicating drink. Among

some of the tribes the mass contained in the cylinder is simply thrown into water, where fermentation proceeds and gives a cloudy alcoholic liquor. J. de Phar. et de Chim., Jan. 1, 1889.

The Nature of Milk. The results of a study of this subject were lately submitted by M. A. Bechamp to the Paris Society of Pharmacy. The author's conclusions are : Milk is not an emulsion. The milky globules are not simple fat globules, but true adipose vesi- cles in a freed condition. Cow's milk contains, beside casein, albu- minoid substances which are not free, being dissolved in combination with alkalis. Human milk is not, properly speaking, a casein milk ; it contains a ferment which is peculiar to it. (See Comptes rendus, XCVI, p. 1508). Milk coagulates spontaneously, i.e., without the aid of vibriones. Z7 Union Phar., Dec. 1888.

Coronilla Scorpioides. Schlagdenhauffen and Reeb have sep- arated from the leaves the bitter principle, coronillin, to which they assign the formula CnH1205. It is a yellowish" powder, soluble in water, acetone and amylic alcohol; slightly soluble in chloroform and ether. Heated with diluted hydrochloric acid an amorphous resin is separated, to which the authors give the name of coronillein. This also occurs as a yellow powder but is not bitter to the taste. It is in- soluble in water, but dissolves in alcohol, acetone and chloroform. Coronillin, say the authors, is a heart poison ; coronillein has no per- ceptible physiological action. Nouv. Rem., Dec. 24, 1888.

Toxic Effects of Cocaine. Dr. Moizard reports that a child aet. four years took by accident 25 cgm. of cocaine. There was no immediate effect ; the child went quietly to sleep. One hour after- ward he awoke in frightful agony. The face was pale, respiration difficult, nausea, pains in the upper portion of the chest, formications, cramps of the limbs, and great muscular agitation. The child could get no rest, and was a prey to terrifying hallucinations. An enema with 50 cgm. of chloral, followed two hours later by one of 30 cgm., was given. The child began to get quiet. During the night it slept, but was frequently awakened by convulsive movements. On the fol- lowing day it was perfectly well. Jour, de Mid., Dec, 1888.

Action of Hyoscine. According to Gley and Rondeau (Gaz. He'd, de Paris, 1888, 10), hyoscine causes dilatation of the pupil, nerve paralysis, arrestation of the heart, suppression of the salivary secretion, paralysis of the cord of the tympanum and of the exci to- secretory nerve. Sleep caused by hyoscine is accompanied with great

A Characteristic Reaction of Bismuth. A solution of iodide of bismuth in iodide of potassium is sometimes used, under the name of iodobismuthate of potash, for the research of the alkaloids. It gives insoluble, orange-yellow compounds with many natural inor- ganic bases, but gives no indication of the nature of the alkaloid found. I have thought, writes M. E. Leger, that this would be oth- erwise should we use such a reagent in finding bismuth. I used a re- agent composed of cinchonine, 1 gm.; iodide of potassium, 2 gm.; distilled water, 100 gm. The cinchonine is dissolved in water with the aid of a few drops of nitric acid ; the liquid is heated and the iodide added. This solution, added to one of nitrate of bismuth gives an orange yellow precipitate. It should be used in excess, avoid- ing solutions containing hydrochloric or sulphuric acid ; it must not contain too much nitric acid. This reagent may be used for metals precipitable by H2S, whose sulphides are insoluble in sulphhydrate of ammonium. It gives, with minimum solutions of mercury greenish- yellow precipitate, turning black with excess; maximum solutions give yellowish-white ; cadmium, white or yellowish ; silver, the iodide if the argentic salt is in excess, yellow if the reagent is in excess ; copper (minimum) precipitate of cupric iodide; maximum, brown maroon, containing iodine, copper and cinchonine ; lead, sulphur-yel- low precipitate, soluble in an excess of nitrate of lead, and containing iodine, lead and cinchonine.

THE ANATOMICAL STRUCTURE OF GRINDELIA RO- BUSTA.1

By Joseph Beauvais, Moscow.

Grindelia robusta belongs to the order of Composite, suborder Tubu- liflorse, and is an herb with oblong, thickish, light green and toothed leaves. Both sides of the leaves have the epidermis covered with a , thick cuticular layer and contain glands and stomata. The glands consist of a one-celled base bearing the gland-cell which is filled with resin. Beneath the epidermis of both the
