As in the case of the gold and platinum nuggets, there is every indication of the silver and copper nuggets having been deposited from solution, and nothing t o indicate that they have undergone fusion, either igneous or hydrothermal.Crystalline Structure of Gold Nuggets. By ARCHIBALU LIVERSIDGE (J. and Proc. Roy. Xoc. New South Vales, 1901, [1900], 34, 259--262).-The examination of the crystalline structure of gold nuggets by etching polished sections, as explained in a previous paper (Trans., 1897, 71, 1125), has been extendedLto specimens from other localities, namely, Vie toria, New Zealand and Klondyke. The structure and appearance of the Klondyke nuggets are quite distinct from those of gold from any other locality. They are very pale in colour, owing to the large amount of silver present. The assays of two gave only 64.550 and 64,622 per cent. of gold, and sp. gr. only 16.23. Texas Petroleum, By WILLIAM BATTLE PHILLIPS (BUZZ.Ulziv. Texas, No. 5 [Univ.

Petroleum in Fossiliferous Limestone from Baden. By CARL ENBLER and E. ALBRECHT (Zeit. angew. Chem., 1901, 14, 913-916).-Three samples of yellow to brown thin liquid oil from cavities in fossil shells in Lias limestone at Roth-Malsch, in Baden, gave on analysis the following results : C, 86-59-87.66 ; H, 12.33-12.92 per cent. ; traces of nitrogen and sulphur are also present. Asphalt, pitch, and solid paraffin were separated from the material. This oil is therefore identical with the mineral oil which occurs on a large scale in Nature, and it has probably been derived from the remains of marine organisms. L.J. S. AnalyseB of Pyrites.

Alkaline Waters from the Cha€k. By WALTER W. PISHER (Analyst, 1901, 26, 202-208).-A correction of the earlier abstract (this vol., ii, 627). In view of the fact that alkaline waters are not only drawn from chalk beneath London Clay, but are obtained from other limestones, beneath Gault, Kimmeridge, Oxford, and Lias clays, the author believes that the alkali chlorides, sulphates, and carbonates are dissolved from the chalk itself and do not conte from extraneous sources. Chalk obtained under London at depths of 500 and 800 feet contains distinct traces 01 sodium carbonate as well as chloride and sulphate. Owing to long-continued percolation, soluble salts have washed out from uncovered chalk but remain in the covered deposits W. W. F. where no natural drainage is possible. w. w. F.

PHYSIOLOGICAL CHEMISTRY. Physiological Chemistry. 665 Minimum Quantity of Oxygen required by Fish ; Poisonous Quantities of Carbon Dioxide in the Water. By J. KUPZIS (Zeit. Nahr.-Genussm., 1901, 4, 631-638).-A record of a large number of experiments with fish (red bream, groundling, whitefish, per&) to ascertain the smallest amount of oxygen required to keep them healthy, and also the influence of carbon dioxide on them. The results are tabulated, It appears that when the amount of oxygen sinks to 1 C.C. per litre of water, the fish begin to show signs of being unwell, and that they perish when the amount is reduced to 0.8-0.5 C.C. As regards carbon dioxide, this only begins to affect the fish when present to the extent of 0.126 gram per litre, and 0.280 gram was required to kill the fish, except groundling.Carbon dioxide is therefore not likely to cause death to fish in aquaria, &c., as it will never accumulate in anything By MAX ENGELHARDT (Chem.

The second paper deals with star-fish eggs, and shows that the stimulus of mechanical agitation will produce the development of embryos. The agitation varied from merely transferring the eggs from one dish to another, to hard shaking in a test-tube, I n all cases agitation led to a positive result. The best results were obtained by violent agitation, especially after the eggs had been in sea water for seven hours. The late gastrula stages were produced. W. D. H. Influence of Food on the Secretion of Enzymes. By PORTIER and BIERRY (Compt. rend. SOC. Biol., 1901, 53, 810-81 l).-Previous observers have shown that the secretion OF enzymes adapts itself to the nature of the food given.The present experiments attempt to discover whether an animal which usually does not secrete a certain ferment will do so when fed on the food on which such a ferment acts. Thus the alimentary canal doos not normally secrete inulase ; dogs and rabbits were fed on Jerusalem artichokes but no inulase was found. Ducks do not normally secrete lactase; one duck was killed after a fifteen days’ diet of lactose, but no lactase was found j another duck, killed ten days later, was found to have abundance of lactase in its intestine.

The amount of ammonia varies with the different proteids, but in every case is greater than that liberated by digestion with dilute acid or alkali and less than that obtained when the albumins are com- pletely decomposed by acids. The quantity of ammonia therefore hever corresponds with the total amino-nitrogen of the proteid. E. w. w. bcornpotJition of Proteids by Trypsin. By JUNICHI MOCHIZUK~ (Be&. ckem. Physiol.

Influence of Urotropin on Intestinal Putrefaction. By WILHELM F. LGBISCH (Chem. Celztr., 1901, ii, 705; from Wierz. med. Presse, 1901).-Urotropin (hexamethylenetetramine) is a good anti- septic. It causes no bad symptoms, and greatly lessens intestinal putrefaction. The ethereal sulphates of the urine are greatly diminished. Under ordinary circumstances, indican is most abundant in the morning urine, and the other ethereal sulphates most abundant in the evening urine. By FELIX REACH (P’iiger’s Archiu, 1901, 86, 247--258).-Absorption is less active in the large than in the small intestine. Gelatin solution is not so well absorbed as albumose solution in the large intestine; addition of 0.7 per cent.of sodium chloride increases the absorption of gelatin until it equals that of albumoses. The salt stimulates the mucous membrane and increases absorption generally. In the small intestine, gelatin is a little better absorbed than albumose. Here, salt increases the absorption of albumose but not of gelatin, Digestion in the Small Intestine. W. D. H, W. D. H.

Digestion and 'Metabolism in Echinoderms. By OTTO COHN- HEIM (Zeit. physiol. Chem., 1901,33, 9-54).- Echinoderms (Holothria, &c.) were selected as the objects of experiment, as it was hoped that in such simple animals the phenomena of absorption would be more' easily solved than in vertebrates.The absorbed material passes into the body-cavity which represents the circulatory system of higher animals. Diffusion will explain the passage of most material into this fluid, except that an active ' water-transport ' must depend on the physiological activity of the intestinal lining cells. The intestine produces a diastatic, an inverting, and, in some cases, a proteolytic ferment. The course of proteid metabolism is by no means clear. Holothuria secretes nitrogen only with the fEces. No ammonia is excreted. The production of carbon dioxide is small, and of t h i s one- third leaves the-body by the intestine. Small holothurians have a more vigorous metabolism than large ones.Alcohol and Proteid Metabolism. By RUDOLF ROSEMANN (PJliiger's Archiv, 1901, 86, 307--503).-A long discussion of the results of others. The main result is that alcohol, within certain limits, is a proteid sparing food. W. D. H. W.

By ARTHUR W. GREELEY (Amer. J. Physiol., 1901, 6, 122-1 25).--Tn Xtentor, a lowering of temperature produces certain morphological changes, which are the same as those produced by increasing the osmotic pressure of the surrounding medium. On raising the temperature again, the reverse process occurs. In X'irogyra, typical plasmolysis may be produced by reduction of the temperature. It is therefore probable that the main effect of lowering the temperature is to cause loss of water, W. D. H. W. D. H. Oxalic Acid in the Organism. .By A. CIPOLLINA (Cheni.

Woch., 1901, 38, 544--547).-Human and animal organs contain only small quantities of oxalic acid ; most is in the spleen.The total amount is about ten times as great as the daily amount in the urine. The spleen, and perhaps also the liver and muscles, are believed to oxidise uric acid with the formation of oxalic acid. Various foods contain larger amounts of the acid, which is stated t o have injurious effects. W. I). H,PHYSIOLOGICAL CHEMISTRY, 669 Origin of Kynurenic Acid in the Organism. By KARL GLAESSNER and LEO LANGSTEIN (Beitr. chem. Physiol.

Dorpat, 1889, and Karplus, Zeit. klin. Med., 22, 210).-When rabbits or dogs are injected with picric acid, by far the greater portion is excreted unchanged, but an amino-compound, a phenol, and a red dye are also found in the urine. The amino-compound is probably picramic acid, and may be detected by means of the azo-dye prepared by extracting with ether, diazotising, and treating with P-naphthol. The phenol is also soluble in ether and gives a brownish-black precipi- tate with ferric chloride. The red dye is present in far larger quantity than either of the preceding compounds, and is insoluble in ether. These substances do not necessarily result from any vital process in the organism, for they are formed when urine, especially that of dogs, is treated with picric acid, and allowed to remain until ammoniacal fermentation takes place, and also by the action of putrefying albumin, or of the alcoholic extract of dogs' or rabbits' liver on picric acid.Dinitrophenol, o-ni trophenol, nitrobenmic acid, nit rosalicylic acid, nitrobenzaldehyde, nitroacetanilide, trinitroiisphthol, nitrourethane, and dinitrohydrox~quinoline do not undergo any change in the animal organism. The physiological action of picric acid, picramic acid, o-nitrophenol, 2 : 4-dinitrophenol, nitrosalicylic acid, nitrobenzoic acid, nitrobenz- aldehyde, and nitrourethane is described in the original paper. Under certain conditions, the paralysing action of strychnine on the peripheral nerves may become more pronounced, and in the case of the nitro-derivatives, dinitrostrychnine, and ' cacostrychnine,' this effect is predominant. Dinitrobrucine and ' cacotheline ' also exert an action resembling that of curare. The nitro-derivative of thebaine, prepared by the action of nitric acid on thebaine at 60°, forms a pale yellow precipitate and has a physiological action different from t h a t of thebaine itself.Nitroatropine and nitrosanguinarine have no effect on frogs, These results show that no common physiological action car1 be ascribed t o nitro-compounds. E. w. w. Syntheses in the Animal Organism. 111. Oxidation Products of Citral in the Organism and some Cyclic Isomerides. By HERMANN HILDEBRANDT (Chena. Centr., 1901, ii, 597-599 ; from Arch. exp.Path. Ylmrrn., 46, 261--273).--The mother liquor of the dibasic acid, C,,H,,O,, found in the urine of rabbits after feeding with citral (this vol., ii, 180) is neither a glycuronic acid compound, sinceit is soluble in ether and does not reduce cupric oxide, nor geranic acid, C1,,H1602, for on digesting with a 65-70 per cent. solution of sulphuric acid i t does not form a-cyclogeranic acid but yields, on the contrary, i+ dibasic ~bcid, C,,H,,O,. This acid separates i 4 white,670 ABSTRACTS OF CHEMICAL PAPERS, crystalline masses, melts a t 9 6 O , is easily soluble in ether or hot light petroleum, but only slightly so in cold light petroleum and combines with 1 mol. of bromine. The original amorphous acid is probably a chain compound, and is converted by the action of the acid into a crystalline, cyclic isomeride.Since both these acids are also found in the urine after feeding with geranic acid, it must be assumed that citral is first oxidised to geranic acid in the organism. Attempts to convert the crystalline acid, C',,H,,O,, melting at 1 8 7 O , into a cyclio isomeride by the action of dilute acid failed, and similarly a cyclic isomeride of the crystalline acid obtained after administering a- and p- cyclogeranic acids could not be prepared. The cyclogeranic acids are, in fact, almost completely oxidised in the organism, and for the same reason cyclocitral arid a- and P-geranic acids are' much less poisonous than the corresponding chain compounds. The mother liquor of the crystalline dibasic acid from which the oily isomeride has been removed, still contains the glgcuronic acid compound of citral. By boiling this compound with dilute sulphuria acid and distilling in steam, a yellow oil is obtained.This oil is neither citral nor p-cymene, since when administered to rabbits neither the acid Ul0Hl4O4 nor cumic acid, but a monobasic acid, C1,H1202, is found in the urine. This acid crystallises from alcohol in long, slender needles, melts a t l l O o , is easily soluble in ether, and is not volatile in steam ; it is not a derivative of cyclocitral, since it is not found in the urine after feeding with this substance. It is isomeric with cumic acid and hence probabry the glycuronic acid compound of citral is related t o p-cymene. E, W. W.First Appearance of Aldehydase in the Mammalian Embryo. BYMARTIN JACOBY (Zeit. physiol. Chem., 1901,33,128-130).-Previous observers have associated 'the oxidising ferments with nucleo-proteids, or with nuclear activity. It is, however, certainly the case that no oxydase, or at least no aldehydase, can be obtained from rapidly growing young mammalian embryos. I n the pig embyro, it is not found until it attains the length of 9 cm. Possibly it may be present in the form of a zymogen a t earlier dates.

Chim., 1901, [vi], 14, 145-151, and 197--803).-Tbe colostrum contains a larger propor- tion of nitrogenous substances than the milk, hut the quantity rapidly diminishes ; it also contains less lactose and a greater proportion of mineral constituents, The amount of f a t is variable but gradually increases.The total solids, fat, nitrogenous substances, lactose, ash, and the refractive index of the fat were determined on terr samples of colostrum, and the results are tabulated in the original ; these analyses indicate the variability in the duration of the colostral period ; at the end of seven or eight days, the lacteal secretion of one subject had attained all tbe characters of milk, whilst that of another still possessed on the tenth day the viscosity and other properties of colostrum. The index of refraction of the f a t diminishes as the time from parturition increases. When the colostrum is treated with alcohol or excess of acetic acid, it yields a white, gelatinous, mucous substance, which, however, in exceptional cases, is deposited spontaneously.This precipitate is soluble in boiling dilyte hydrochloric or sulphuric acid, with formation of an acid albumin and a substance which reduces Fehling's solution. The substance precipitated by alcohol is found to contain considerably less nitrogen than would be the case if it consisted only of albumin and casein. These facts show that the colostrum contains normally a true mucin, for which the author proposes the name luctornucin. By ADOLF JOLLES and JOSEF K. FRIEDJUNG (Chem.

The film is formed of unchanged, dried proteid in the case of non-coagulable proteid, and in that of coagulable proteid if the temperature is kept below their coagulating point.

The filtered liquid thus prepared contains the oxgdase, as i t imparts an azure-blue colour to guaiacum resin. The action OF the enzyme is destroyed by dilute hydrocyanic acid, chloroform, hydroxylamine, quinol, or pyrogallol, but is not influenced by aqueous phenol, thymol, or mercuric chloride. Like the vegetable oxydases, this enzyme contains a small proportion of manganese.T. H. P. Electrometric Determination of the Acidity of Urine. By LADISLAUS VON RHORER (Pjiiger’s Archiu, 1901,86,586-602).--E.M.F. determinations on the lines indicated by Bugarszky and Liebermann (Abstr., 1898, i, ‘716) show that the concentration of H* ions in urine is about 30 x 10-7. The author considers that they are primarily produced by the dissociation of the dihydrogen phosphates.

Arsenic in the Organs of the Body. W. D. H.Localisation and Dissemination of Antimony in the Animal Organism. By G. POUCIIET (Compt.

It therefore differs markedly from arsenic. If antimony is administered with small quantities of arsenic, the toxic effect of the latter seems t o be increased, but the distribution of the two elements in the organism is not affected. Physiological Action of Suprarenal Extract. By JOHN N. LANGLEY (J. Physiol., 1901,27, 237-256).-Suprarenal extract causes a brief but active secretion of the salivary and lacrimal glands.This is not affected by degeneration of the post-ganglionic fibres of the superior cervical ganglion, or by small doses of atropine, but after a large dose of atropine, there is no secretion caused by the extract. It has no certain effect on the secretion of sweat. It increases secretion of bile. It acts differently on different involuntary muscular organs, causing, for instance, inhibition of the bladder, stomach, gall bladder, &c., and contraction of the anal sphincters, uterus, and blood vessels.

Comparative Investigations of the Pharmacological Actions of some Purine Derivatives. By OSWALD SCHMIEDEBERG (Bey., 1901, 34, 2550--2559).--Experiments were made with frogs and rabbits ; the drugs were dissolved in either water or sodium carbonate solution, and were adminstered either internally or by injeotion into the blood. The action of caffeine and theobromine is already known to be twofold. I n the first place, they act on the central nervous system, producing an ' increased sensibility t o external stimulus, developing into tetanus as the dose is increased, and culminating in paralysis when the dose is large. Secondly, they act on the muscles, facilitating the contraction of these at first, but producing muscular rigor when the dose is larger ; the rigor may be local when the drug has been injected into the blood at'a particular spot.Under the microscope, they are seen to coagulate the muscle-plasma. The relative degree of these two actions varies from substance to substance; with theobromine, the action on the muscles is greater in proportion to that on the nervous system than it is with caffeine. Parallel with the action on the muscles is a diuretic action, the two increasing together. The nervous action depends on the presence of nitrogen in the molecule, for it is exhibited also by ammonia and ammonium salts. On the other hand, the muscular action is characteristic of the purine ring. Purine itself exhibits both actions. Introduction of oxygen or alkyl groups affects the degree of the two actions, both absolutely and relatively ; no regularities could be observed in this respect, however.Such regularities as exist are probably masked by the fact that, owing to the difference in solubility and other causes, the rate at which the drug penetratesto the nerve cells and muscle fibres varies very much from case to case. Probably it is for some such reason that 7-0xy- purine produces no muscular rigor and 2-oxypurine no tetanus, whereas with the 1 : 6-dimethyl derivative of the first and 1 : 3-dimethyl derivative of the second the missing action is manifested; the Erst two substances are insoluble in water and only slightly soluble in aqueous sodium carbonate, whereas the second two dissolve readily in water. The introduction of alkyloxy-groups produces a hypnotic or narcotic action, which may almost mask the tetanus. Several pocu- liarities were observed ; for instance, 3 : 4 : 6-trimethylxanthine is only slightly active whilst 1 : 4 : 6-trimethylxanthine (caffeine) is much more so, and uric acid is not active, whilst its 1 : 3 : 4 : 6-tetramethyl deriva- tive is. Experiments were made with the following substances :-Purine 7-oxypurine (hypoxant hine), 1 : 6-dimethylhypoxanthine, 2-oxypurine, 1 : 3-dimethyl-Z.oxypurine, 1 : 4 : 6-trimethyl-6 : 7-dihydro-5-oxypurine (deoxycaff eine), 5 : 7-dioxypurine (xanthine), 4-methylxanthine, l-methylxanthine (heteroxanthine), 1 : 6-dimethylxanthine (theo- bromine), 4 : 6-dimethylxanthine (theophylline), 1 : 6-dimethylxanthine (paraxanthine), 3 : 4 : 6-trimethylxanthine, 1 : 4 : 6-trimethylxanthine (caffeine), 4-methyl-1 : 6-diethylxanthine, 1 : 2 : 4 : 6-tetramet.hy1- xanthine (2-methylcaffeine), 2 : 7-dioxypurine, 1 : 3-dimethyl-2 : 7-di-VEGETABLE PHYSIOLOGY AND AGRICULTURE. 675 axypurine, 1 : 3 : 6-trimethyl-2 : 7-dioxypurine (isocaffeine), 2 : 5 : 7- trioxypurine (uric acid), and 1 : 3 : 4 : 6-tetramethyluric acid.

VEGETABLE PHYSIOLOGY AND AGRICULTURE. 675 Chemistry of Vegetable Physiology and Agriculture. Physiology of Bacillus Pyocyaneus. By OSCAR LOEW and YOSHINAI KOZAI (Bull. CoZZ. Agr. Tokyo Imp. Univ., 1901,4,227-236). -As regards the nutrition of B. pyocyuneus, it was found that asparagine is more suitable than leucine, tyrosine, glycine, hydantoin, or creatine, and that acetates are better than tartrates. Acetates and glycerol promote the formation of mucus, but not to the same extent as broth. I n the production of the bacteriolytic enzyme, peptone was found to be the best nutrient; mucus is not formed to any extent. The presence of a little glycerol is beneficial, but increasing the amount of magnesium sulphate to 1 per cent. is without advantage. N. H. J. M, Biochemical Studies on the Tubercle Bacillus.By P. A. LEVENE (J. Ned. Research, 1901, 6, 135-144).-Elementary analysis of the tubercle bacilli prepared on different media gave widely different results, especially in the amount of alcohol-ether extract. Differ- ences were also observed in the amounts of proteid andof free nucleic acid present. By fractional heat-coagulation, the proteid material can be separated into three substances, each of which contains phosphorus. The nucleic acids separated vary much in composition; some of the preparations made are looked on as purer than the others. The only carbohydrate studied was one which closely resembles glycogen ; this appears to be always present. By GERLAC'H and VOOEL (Cent?.. Bakt. Par., 1901, [ii], '7, 609-623).-Soil and stable manure contain several varieties of motile, non-spore-forming bacteria which are capable of converting the nitrogen of nitrates, nitrites, ammonium salts, and urea into insoluble proteids.Cultivated in a medium containing mineral salts, 0-5 per cent. of dextrose, and 0.3 per cent. of sodium nitrate, a certain amount of nitrite is formed, but after 5-10 days neither nitrate nor nitrite remains, whilst the total nitrogen W. D. H. Albumin-forming Bacteria,676 ABSTRACTS OF CHEMICAL PAPERS, of the solution is unaltered, the whole of i t being present in the in- soluble proteids formed. No ammonia is produced. The nitrogen of ammonium salts is less readily assimilated and that of urea still less readily. I n neither case is there any formation of nitrate or nitrite.When a solution containing urea is inodated*with these bacteria and with a species capable of converting urea into ammonium car- bonate, a certain amount of the ammonia produced is utilised by the proteid-forming bacteria, but a considerable loss takes plnce by evaporation of the ammonia from the solution, SO that the presence of proteid-forming bacteria in stable manure is not sufficient to prevent loss of ammonia in this way. I n the presence of denitrifying organisms, practically the whole of the nitrogen of sodium nitrate is evolved as nitrogen, the denitrifying action proceeding much more rapidly than the conversion of the nitrogen of’ nitrates into proteid. When nitrate is added to garden soil containing some straw as a source of carbon, a similar action goes o n ; soil contains both denitrifying and proteid-forming organisms, and the result is not affected by inoculating with eit,her or both species.A.

BREMER (&it. h’alw.-Genussm., 1901, 4, 721-744 and 769-780).-A chemical and bacteriological investigation of the changes undergone by cottonseed-meal when decomposed by micro-organisms. Three samples of meal each contained moulds and bacteria ; the moulds only grew when the meal contained more than 14 per cent. of moisture. The growth of the moulds was accorupanied by a decomposition of t h e fats and the nitrogen-free extractives, The bacteria, on the other hand, had a stronger action on the proteids. Experiments with pure cultures showed that the moulds decompose, not only fats, but also fatty acids, both being apparently converted directly into water and carbon dioxide.R. H. P. Monilia Sitophila, a Technical Mould from Java. By F. A. F. C, WENT (Centr. Bakt. Par., 1901, [ii], 7,544-550 and 591-598. Com- pare this vol., ii, 41 l).-This mould brings about hydrolysis of fats, pep- tonisation and further decomposition of proteids and amylolysis, and pene- trates the walls of vegetable cells, breaking up the cellulose. The best single medium for its cultivation is peptone. In presence of ammonium nitrate, as a source of nitrogen, i t can derive its carbon from raffinose, maltose, dextrose, starch, commercial lavulose, as well as in a less degree from many other carbohydrates and allied compounds.I n a similar manner, when the source of carbon is dextrose, the best source of nitrogen is found to be peptone or tyrosine. Glycerol, by itself, is only very slowly assimilated, but when both glycerol and rafinose are employed, the yield is far greater than when raffinose alone is present. It seems probable that the glycerol is oxidised, whilst the raffinose is assimilated for the purpose of mycelium formation, The mould only develops sparingly under anaerobic conditions, forming alcohol and esters, the nature of which could not be determined. A. H.VEGETAkLE! PHYSIOLOGY AND AGRICULTURE. 674 Agglutination of Yeast. By H. P. BARENDRECHT (Centr. Baht. Par., 1901, [ ii],7,683--627).-Some varietiesof yeast are rapidlyagglutinated in the presence of acids.The optimum concentration of acid varies slightly, but corresponds on the average with N/300 sulphuric acid. The action appears to be a function of the concentration of the hydrogen ions, since weak acids, such as acetic acid, must be present in larger amount, and their action is much diminished by the presence of a salt of the same acid. When the amount of acid is increased beyond the optimum, the agglutination takes place more slowly and less perfectly. Different varieties of yeast show considerable differ- ences in the ease with which they are agglutinated, and the nature of the medium in which they have been cultivated also modifies the result, ammonium salts being favourable to the occurrence of agglu- tination.The agglutination which sometimes occurs in the manufsc- ture of pressed yeast is not due to this cause, but is produced by the viscous substances formed from sucrose by an organism (Leuconostoc agglutinuns) which is always found in such samples. Experiments with Yeast Cells in Concentrated Saline Solu- tions. By CHARLES CLERFEYT (Bull. Acud. Rop. BeZg., 1901, 23, 337--348).-Yeast cells can be accustomed t o grow in concentrated saline solutions; those accustomed to any one particular salt will grow a t a slower rate than ordinary yeast cells iu a solution of another salt.

The proteolytic enzyme of yeast-yeast trypbiu of Kutscher, yeast endotrypsin of the authors-diff ers essentially from pancreatic trypsin in the fact that it becomes much less active in the presence of acid. Distribution of Acidity in Stems, Leaves, and Flowers. By A. ASTRUC (Compt. Tend., 1901, 133, 401--493).-The study of the acidity of plants, which was hitherto confined chiefly to oil-yielding plants, has been extended by the author to a large number of widely different families.It was found that the acidity of the stems diminishes with the distance from the top of the stem, and that the acidity of the leaves especially the growing zone, is greater than that of the stems. I n the case of flowers, the acidity diminishes as development proceeds. The most recent growth always shows the greatest acidity, and there is a close relation between the production of acids on the one hand and of intensity of growth on the other.

When subjected to artificial pepsin digestion, a portion of the proteid dissolved, and on precipitating the solution with alcohol, the products still contained iron. The residue, insoluble in pepsin, contains N 5-10 and Pe 05-1.0 per cent. The iron compound differs from hsmatogen in being partially dis- solved by artificial pepsin digestion ; both the dissolved and undissolved portions liberate small quantities of iron when treated with 0.2 per cent. hydrochloric acid. It is also much more sparingly solublein dilute ammonia than hzematogen.N. H. J. M. Chemical Changes in Apples during Ripening. By RICHARD &TO (Chem. Centr., 1901, ii, 553 ; from Proskauer Obstbau-Zeit., 1901, July).-The following changes have been found to take place in apples when allowed to ripen on the tree or when stored. The amounta of water and ash of the dry substance decrease as the fruit matures, whilst, on the other hand, the quantity of dry substance increases. Unripe apples contain a maximum of about 4 per cent. of starch which at first only slowly, but afterwards more rapidly, decreases until it disappears entirely in the ripe fruit. The amount of cellulose does not change during the initial stages of maturing, and the content of sucrose is also not affected by ripening but decreases on prolonged storing.The nitrogenous substances attain a maximum in the ripe apple but decrease on storing. The sp. gr. of apple must increases on keeping, whilst the total acids calculated as malic acid and the small quantity of pectic acid decrease. The quantity of sugar estimated by Ochsle's method is on the average 0.7-0-9 per cent. less than that of the total sugar, dextrose, and extract determined by Allihn's method; the data obtained by both methods show a constant increase during the storing of the must, E.

Rundschau, 1890, 29-38) that the bark of Robiniu l’seud- acacia contains a toxic proteid, for which he now proposes the name robin.This substance has an acid reaction, is soluble in water and salt solutions, and is reprecipitated by acids; i t is coagulated by heat with complete loss of its poisonous properties, It gives the usual colour reactions of proteids, and yields about 4 per cent. of ash which contains a considerable amount of iron. It also possesses the proper- ties of an enzyme, effecting the hydrolysis of both amygdalin and potassium myronate. It is capable of coagulating the casein of milk, and of agglutinating the red blood corpuscles of certain animals. The bark also contains one or more substances of an alkaloidal nature which could not be isolated owing to their decomposition, with formation of ammonia and small quantities of an amine.When an extract of the bark is boiled with hydrochloric acid, syringic acid and dextrose are produced, together with a red, amorphous substance which is probably syringenin. Tannic acid, some amorphous colouring matter, fat, and resin are also found in the bark. The leaves of the plant appear to contain neither a soluble proteid nor a n alkaloid, E. G. Physiological Significance of Colchicine in different varieties of Colchicum and Merendera. By GIACOMO ALBO ( A d . Xci. Phys. Nat. GenBve, 1901, [iv], 12, 227-236).-Colchicine was found to occur, not only in Colchicum uutumncde, but also in C. laetum, C. vuriegutum, C, Bisignani, C. Cupuni, C. uerutri&olium, C. Bivonue, C. persicum, C. neupolitunum, C. montunum D.Bertolini, C. montanum v, ungustifolium, and C. autumnale v. 3. puiyureus. It also occurs in the leaves of Merendera caucusica and M. sobolifem, its localisation being almost identical with that of Colchicum. The amount of the alkaloid extracted from C. Cupuni was 0.464 per cent. I n growing plants, the alkaloid tends to migrate to the newlg-formed portions and accumulates in the seeds, especially during maturation ; it is localised in the parenchymatous cells of the placenta, and is never found in dead cells or in intracellular spaces (compare Arch. ItaZ. Biol,, The conclusion is drawn that colchicine is not a waste product of protoplasmic activity, but that it is a reserve substance which con- tributes to the nutrition of the plant. R81e of Oxydase in the preparation of Commercial Black Tea.By K. As6 (Bull. Coll, Agr. Tokyo Imp. Uniu., 1901, 4, 254-259).-The colour of black tea is shown to be produced by the action of oxydase on tannin. I n the case of green tea, the oxydase is destroyed during the first treatment in its preparation. Tea leaves contain nucleo-proteids in which both iron and manganese are present. Tea Plant. By U.

Etiolated and normal shoots contain about the same amounts of theine.Coty- ledons of germinating seedlings contain very little theine ; stems and roots, moderate amounts. The largest amounts of theine are contained in the leaves, and the quantity present is nearly proportional to their development. Sodium nitrate has no marked effect in increasing the amount of theine ; this makes it probable that theine is a product of katabolism, and not of synthesis like nsparagine. The dormant buds are moderately rich in theine, but the bark and trunk of the tea plant only contain doubtful traces. Localisation of Theine in Tea Leaves. By U. SUZUKI (Bull. ColE. A ~ Y . Tokyo Jmp. Univ., 1901, 4, 297-298).-On immersing a section of a tea leaf in 0.5 per cent. theine solution, a very marked formation of proteosomes was observed in the cells of the spongy and palisade tissues.As there was no production of proteosomes in the epidermal cells, it is evident that these cells are free from active proteid, and contain the whole of the theine of the leaves. This conclusion was proved to be caused by keeping a section of a tea leaf in a tannin solution (about 3.4 per cent.) for 2 days; a voluminous precipitate consisting of minute globules was produced in the epidermal cells, whilst the other tissues showed only a slight turbidity. The precipitate dissolved in very dilute ammonia and consisted therefore of theine tannate. Occurrence of Paraffins in Tobacco Leaf, By RICHARD KISSLING (Chenz. Zeit., 1901, 25, 684).--The author dissents from the view expressed by Thorpe and Holmes (Proc., 1901, 17, 170), that the waxy substance which he previously described (Abstr., 1881, 173) as an ester of a high fatty acid can be a mixture of paraffins.By JOSEF HABERMANN (Zeit. physiol. Chem., 1901, 33, 55-125. Compare Kissling, Abstr., 1882, 906 ; Thoms, Abstr., 1900, ii, 428).-The method employed for collecting the products of combustion was somewhat similar to that used by Kissling, except that the burning was intermittent and not continuous. This was accomplished by the aid of a suitable aspirator, which is described in the paper. The results obtained indicate that only a small portion of the nicotine passes into the aspirated smoke. For the estimation of nicotine, the author has employed Kissling's method, using, however, methyl-orange instead of rosolic acid as indicator.The smokefromeachof thediff erent kindsof cigars employed contained hydrogen sulphide and carbon monoxide, but hydrogen cyanide was not detected, although there is a possibility that some small amount was formed, and condensed before reaching the flask in which the test was made. The amount of carbon dioxide was on the average four times that OP the monoxide, and the shape of the cigar does not appear to aflect this ratio.

Ver.deut. Zuckerind., 190 1, 720-745)- The residues from the desaccharification of molasses by the strontia process furnish a suitable sugar-free material for studying the non- saccharine components of molasses. The author discusses the literature of the subject, and then describes his own experiments made on various samples of such residues. Of one sample, 20.6 per cent. of the dry substance was found to dissolve in ether, and of the ether-soluble por- tion, 4.92 per cent. consisted of formic acid, 20.88 of acetic acid, 20.9 of lactic acid, and about 3 per cent. of propionic, valeric, and butyric acids; succinic acid is also present. The methods of separating and determining these acids are described. By HERBERT H. COUSINS (Bull. Bot. Dept.

Testing of Various Soils as regards their Manurial Require- ments. By BERNHARD SCHULZE (Bied. C'entr., 1901, 30, 585-586; from Jahresber. cbgrik. -diem. Versuchsstat. Land w.-Xacmrnen Prov. Schlesien, 1899, 15).-Pot experiments were made with the following soils (1) humous loess (K,O, 0.202 ; P205, 0.069 ; CsCO, and humate, 0.184 per cent.); (2) loamy sand (K,O, 0.042; CaO, 0.519, and P,O,, 0.033); (3) sandy lotm (K,O, 0.062 ; CaO, 0.318, and P,O,, 0.075 per cent.) ; (4) loam (K,O, 0.113; CaO, 0.319, and P,O,, 0.075 per cent.); (5) black loam (K,O, 0.262 ; CaO, 1.193, and P,O,.0.142 per cent.). Oats were grown in all the soils, and peas in (5) and (6). The yields of oats and peas obtained without manure, and with nitrogen, potassium, lime, and phosphoric acid in various mixtures, are given in tables. As regards the wants of tbe different soils, the conclubion is drawn that No. (2) requires a complete manure, that (2) and (3) decidedly require phosphoric acid, and that (4) and (5) require phosphoric acid N.

The amount of potassium in (4) sufficed for oats, but not for peas; (5) required potash for both crops, but especially for peas. N. H. J. M. Assimilation of Nitrogen and Phosphoric Acid at Three Periods of Growth. By KURT BIELER and K.As6 (Bull. Coll. Agr. Tokyo Imp. Uniw. 1901, 4, 241--254).-Pot experiments with three cereals (barley, wheat, and oats), and two cruciferous plants (rape and mustard) grown in sand manured with the same amounts of double superphosphate, potassium and calcium carbonate, and ammonium sul- phate. Plants were taken up for analysis after 24 and 4 months and a.fter flowering. The amounts of dry produce, including roots, nitro- gen, ash, and phosphoric acid were determined in each case. It was found that the barley plants took up about the same amount of nitrogen as the same number of wheat and oat plants, and that although the amount of total ash of the barley a t the end of the ex- periments was the greatest, the amount of phosphoric acid was the smallest. The manure applied sufficed for the complete development of the wheat and oats, but not for barley.Rape plants were found to contain rather less nitrogen and phos- phoric acid a t the end of the third than a t the end of the second period, although there were gains both in dry matter and ash. Both the cereals and Crucifem assimilated about the same amount of nitrogen, but the latter, especially rape, took up more phos- phoric acid; of the three cereals, wheat assimilated the greatest amount of phosphoric acid. N. H. J. M. Examination of Hay to ascertain the Changes in the Amounts of Food Constituents, Phosphoric Acid, and Potash caused by different Manuring. By BERNHARD SCHULZE (Bied. Centr., 1901, 30,583-585 ; from Jaliresber. agrik-chena. Versuclisstat. Landw.-Kanzmer PYOV.Schlesie7i).-Analyses of the hay from three meadows, each divided into heveral plots under diff ereut mmurinl treatment, showed that potassium manures, when applied alone or with lime, had the greatest effect on the yield of hay; the crop also con- tained the greatest amount of potassium. The yield of proteids did not always have a decided relation to the manure applied, but was highest when potassium manures were applied alone. The production of carbohydrates was, however, in - direct relation to the potassium manuring. Phosphoric acid and calcium did not give any definite results, and the production of fat in the plants could not be directly connected with any manure constituent. Influence of the Amount of Water in the Soil, and the Manure, on the Yield and Composition of Italian Rye Grass and Clover. By CONRAD VON SEELHORST, N.GEORGS and FAHREN- HOLTZ (Bied. Cent?.., 1901, 30, 625-630 ; from J. Lmndw., 1900, 48, 265. Compare Abstr., 1899, ii, 609, and this vol., ii, 274).-Clover and rye grass were grown in small plots of loamy soil without and with minerals ; the grass had sodium nitrate in addition to mineral manure. Tbcie were three sets of plots : (1) with small, (2) with moderate, itnd N. H. J. M.VEGETAkLE PHYSIOLOGY AND AGRICULTURE. 683 (3) with large amounts of water. The yields and composition of the produce are recorded. It was found that an increased supply of water in the soil increased the yields of clover and its chief constituents ; i G also increased the yield of grass, but not, to any extent, the amount of proteids in the grass, owing to insufficient nitrogen in the soil.The quality both of clover and grass is injured by excess of water in the soil. Boththe proteid and the fat in the first cutting of clover were reduced in quantity. The percentage of ash in clover and grass increased with the amount of water in the soil. By J. DUGAST (Ann. Agron., i901, 27, 444-445; from J.

Agr. prat., 1901, i, 539).-Different varieties of potatoes produced starch grains varying widely in size. As regards the effect of manures, it was found that potassium chloride always produced starch of good quality, the grains being smaller than when the sulphate was employed. Complete manure produced the largest grains, whilst dung alone gave less satisfactory results than when employed in conjunction with phosphates. Of the different manures, phosphoric acid always had the greatest effect. Artificial Manures and Humus. By K. DE VRIES (Ann. Agvon., 1901, 27, 443-444; from Deut. Imdw. Presse, 1901, 296).- The results of analyses of Groningen soils, some for a long time manured only with artificial manures and others which had received farmyard manure alone, showed that the different manuring had had no effect on the amount of humus. The fact that the soils which had only artificial manures showed no exhaustion of humus is at- tributed to the humification of the large crop residues. Fermentation of Nitrogenous Substances in Farmyard Manure, By I). PIERRE DEHERAIN and C. DUPONT (Ann. Agron., 1901, 27, 401--427).-The ferments of farmyard manure transform the nitrogen of urine, uric acid, and hippuric acid into ammonium car- bonate. Hippuric acid only ferments in presence of air, whilst urea and uric acid ferment in an atmosphere of carbon dioxide. I n practice, the fermentation is not rapid enough to prevent the addition of litter containing urine to manure heaps without loss of ammonia. The proteids of farmyard manure ferment very incompletely in absence of air, and not a t all in very alkaline media. Most of the nitrogen is converted into ammonium carbonate, a small quantity being liberated in the free state. Carbon dioxide, hydrogen, methane, and, frequently, hydrogen sulphide are produced. N.

684 ABSTRACTS OF CHEMICAL PAPERS. Analytic a1 C h e mis try. Practical Methods for the Rapid Spectroscopic Analysis of Gases. By MARCELLIN P. E. BERTHELOT (Ann. Chim. PhYS., 1901, [vii], 23, 447-482).-A description of an apparatus employed in the spectroscopic examination of gases under approximately atmospheric pressure, and a table giving the wave-lengths of the prominent lines exhibited under these conditions by volatile elements and compounds. G. T. M. Indicators for Use with Artificial Light. By A. KUFFERATH (Zed. angew. Chem., 1901, 14, 916-918).--8 series of experimentsANALYTICAL CHEMISTRY 685 with methyl-orange, fluorescein, cochineal, corallin, pnitrophenol, alizarin-green B, resazurin, and luteol (Autenrieth, Abstr., 1895, i, 572) to ascertain whether these can be successfully used in titrations when using artificial light.The conclusion drawn is that the source of light is immaterial when using p nitrophenol or fluorescein, but when working with the other Indirect Weighing of Quantitative Precipitates ; Rapid and Accurate Method for Determining the Weight of a Pre- cipitate without Separating it from the Liquid. By R. W. THATCHER (J. Amer. Chem. Xoc., 1901, 23, 644-668).-The author’s method is briefly as follows :-The metal to be determined is converted in the usual manner info an insoluble compound. The bulk of the liquid is, if necessary, removed, and the remainder, together with the precipitate, is introduced into a pyknometer of known weight and capacity and the whole is weighed. A portion of the clear liquid is then taken off and its sp.gr. ascertained by using a smaller pykno- meter. From these data and the known sp. gr. of the precipitate, the weight (x) of the same may be calculated by using the formula x = d(a - bd’)/d - d’, in which a represents the total weight, 6 the total volume, d the sp. gr. of the precipitate,and d’ the sp. gr. of the liquid. Specific gravities of precipitates may be readily ascertained as follows. A known weight of, say, pure sodium chloride is pre- cipitated with a sufficiency of silver nitrate, the precipitate is intro- duced in the pyknometer, which is then filled and weighed; x now being the known quantity, d may be in turn found by calculation. To find the sp. gr. of calcium oxalate, a known weight of pure calcium carbonate is dissolved and precipitated with ammonium oxalate, &c.indicators acetylene light is preferable. L. DE K. L. DE E(. Automatic Filter-Washer. By JAMES MARION PICKEL (J. Amer. Cliem. Soc., 1901, 23, 589--593).--The author has devised an auto- matic fiiter-washer which is well adapted for washing the soluble phosphates out of commercial fertilisers. A reservoir containing the liquid with which the washing is to be effected is connected by a rubber tube provided with two clamps to tbe delivery vessel; by means of these clamps the rate of flow can be regulated. In the interior of the delivery vessel is a small intermittent siphon which delivers the liquid on to an inverted funnel covering the substance to be washed ; this funnel is of such a size as to nearly cover the fiiter- paper contained in a larger funnel.Analysis of Gases by means of the Electric Spark. By MARCELLIN P. E. BERTHELOT (Ann. Chim. Phys., 1901, [vii], 23, 433-447).-Pure oxygen, when contained over mercury and sub- mitted to the action of the electric spark, yields a small amount of ozone, which superficially oxidises the mercury; a mixture of oxygen and nitrogen gives rise to nitrogen peroxide, the product giving a characteristic pink coloration with ferrous sulphate and concentrated sulphuric acid. Hydrogen is not affected by the electric discharge and this agent does not readily promote its com- bination with nitrogen to form ammonia. Nitrogen under these E. G.686 ABSTRACTS OF CHEMICAL PAPERS. conditions reacts with acetylene or ethylene, giving rise to hydrogen cyanide (compare Abstr., 1897, i, 330).Argon and helium, when mixed with benzene vapour and sparked in the presence of mercury, exhi bit respectively their characteristic green and orange-coloured luminescent spectra. Nitrogen monoxide and trioxide, when sparked for some time, yield a mixture of nitrous fumes, oxygen, and nitrogen. The oxides of chlorine detonate under the influence of the electric spark, yielding their constituent elements. Sulphur dioxide is partially decomposed into the trioxide and free sulphur ; carbon dioxide after prolonged action yields an appreciable amount of carbon monoxide and oxygen. Carbon monoxide, under similar conditions, yields a mixture of carbon and the dioxide. The bydrides of chlorine, bromine, and iodine are partially decomposed under the influence of the electric spark, whereas hydrogen fluoride is not affected.Water, and the hydrides of sulphur, selenium, and tellurium, undergo a similar decom- position; in all these cases, the action becomes more complete as the atomic weight of the non-metal increases. Ammonia and phosphine are completely decomposed after 2 hours’ exposure to the electric discharge ; arsine, stibioe, and hydrogen silicide are also rapidly re- solved into their elements. The hydrocarbons also undergo decom- position, acetylene being in each case an intermediate product; this substance subsequently gives rise to hydrogen and carbon, a limit to this reaction being attained when the volumes of the hydrogen and unaltered hydrocarbon are in the ratio 7 : 1.Compounds containing carbon, hydrogen, and oxygen decompose under these conditions, yielding acetylene, water, and the oxides of carbon. Carbon oxysulphide gives rise t o carbon monoxide and sulphur, whilst carbon disulphide is resolved into its elements. The mercaptans and thio-ethers are decomposed, yielding hydrogen sulphide, acetylene, hydrogen, sulphur, and carbon. The alkyl chlorides furnish hydrogen chloride, the corresponding bromides give rise to hydrogen bromide, and the iodides to iodine; in addition to these products, the alkyl haloids yield acetylene, carbon, and hydrogen, Phosphorus trifluoride is resolved into phosphorus and the pentafluoride; the latter compound is not altered by the electrical discharge and in this respect resembles boron chloride and the fluorides of boron, silicon, and sulphur.Cyanogen and cyanogen chloride are resolved i n to their elements. Hydrogen cyanide is partially dissociated into acetylene and nitrogen. Methylamine and its analogues yield hydrogen cyanide, acetylene, carbon, and hydrogen. G . T. M. Estimation of Solution of Hydrogen Peroxide, By WILLIAM A. H. NAYLOR and C. S. DYER (Phavm. J., 1901, [iv], 13, 131-132). -The gasometric method of estimating solutions of hydrogen peroxide by means of potassium permanganate and sulphuric acid in a nitrometer charged with brine is rendered inaccurate by the evolution of chlorine, which is incompletely absorbed by the water; the results furnished by this process are considerably higher than those obtained by coIlecting the oxygen over mercury, but if a saturated solution of magnesium sulphate is substituted for the brine, the results agree with those obtained when mercury is used.I n any case, however, theANALYTICAL CHEMISTRY. 687 permanganate method yields somewhat higher results than that of JHason (Chemist and Druggist, 1881, 56), which involves the use of potassium dichromate and gives concordant results whether the oxygen is collected over brine, saturated solution of magnesium sulphate, or mercury. E. G. Estimation of Chlorate in Electrolytic Bleaching Solutions and Potassium Chlorate Lyes. By HUGO DITZ (Chern. Zeit., 1901,' 25, 727-728).-A slight modification of the former appar- atus (Abslr., 1900, i i , 241). It is now also stated that the reaction between potassium chlorate, potassium bromide, and hydrochloric acid is complete within five minutes ; potassium iodide is then decomposed By WILLIAM A.NOYES and L. LESLIE HELMER (J. Amer. Chern. Xoc., 1901, 23, 675--679).-Five grams of the finely divided sample are dissolved in 200 C.C. of water and 8 C.C. of bromine, and filtered off from any insoluble matter, which must afterwards be tested for sulphur by fusion with oxidising mixture in the usual manner, or 5 grams of the sample are mixed with 7 grams of potassium chlorate and gradually added to 120 C.C. of nitric acid of sp. gr. 1.2 containing 1 gram of potassium bromide; the whole is then evapor- ated t o dryness, and the residue dissolved in hydrochloric acid, when any insoluble matter must also be examined for sulphur.Care should be taken to avoid contact with sulphurous fumes from the illuminating gas. I n either case, the iron solution is poured into 130 C.C. of 10 per cent. ammonia, and the whole diluted to 500 C.C. and filtered through a dry filter. Three hundred C.C. of the filtrate are evaporated to 100 c.c., one drop of hydrochloric acid of sp. gr. 1-12 is added, and the sul- phuric acid precipitated as usual by means of barium chloride. The test experiments prove the great accuracy of the method. Estimation of Sulphur in Oils. By FERDINAND JEAN (Ann. Chim. anal. uppZ., 1901, 6, 321).-So-called cooling oils contain a small quantity of added sulphur, sometimes to the extent of 0.7 per cent. The author estimates this as follows : 5 grams of the sample are heated at about 150' in an enamelled dish, and saponified by adding 4 C.C.of aqueous sodium hydroxide of sp. gr. 1.33 and 2 C.C. of alcohol; the whole is evaporated to dryness with constant stirring. The mass is dissolved in hot water and the soap separated by saturating the liquid with s a l t ; the precipitate is then washed with brine. The filtrate is mixed with an excess of seltzer water, and the sulphide titrated with N/10 iodine, using starch as indicator. Treated in this manner, a sample of colza oil gave 0.031, and one of Gravimetric Estimation of Tellurium. By ALEXANDER GUTBIER (Bey., 1901, 34, 2724--2726).-In the gravimetric estimation of tellurium by reduction to the metal, hydrazine hydrate or hydrochloride may be employed with great advantage, as the reduction can be carried out in neutral solution, and the reoxidation of the tellurium t o telluric by the liberated bromine and the free iodine titrated.L.

Five analyses of telluric acid by this method showed a maximum error of 0.2 per cent. and two analyses of the dioxide gave values within 0.1 per cent. of the calculated percentage of tellu- rium. T. M. L. [ Estimation of Nitrogen] in Urine for Clinical Purposes. By ADOLF JOLLES (Chem. Centr., 1901, ii, 663-664 ; from Centr. inn. Med., 1901, 22, 719-723).-Five C.C. of urine are mixed with 5 C.C. of water, and 5 C.C. of this are diluted t o 150 C.C. and heated with 2 C.C.of sulphuric acid. A solution containing 4 grams of potassium permanganate per litre is now added 1 C.C. at the time, until after 15 minutes’ boiling the colour is no longer discharged. By this means, the various minor nitrogenous constituents of urine, uric acid, purine bases, hippuric acid, oxaluric acid, proteids, carboxylic acids, and allantoin furnish products which, like urea and ammonia, yield the whole of their nitrogen as gas when treated with bromine in the presence of sodium hydroxide. The liquid is decolorised by adding a little oxalic acid, made alkaline with sodium hydroxide, and the nitrogen then liberated Estimation of Ammonia in Animal Liquids and Tissues. By MARCELLUS NENCKI and J. ZALESKI (Zeit. physiol. Chem., 1901, 33, 193--209).-The percentages of ammonia obtained by the method previously described (Abstr., 1897, ii, 343) vary with the proportions of blood and lime-water employed; the authors now recommend the distillation of the blood itself diluted with water, as it contains suffi- cient alkali to decompose all ammonium salts present.Good results are also obtained when magnesia is employed in placs of lime-water ; the addition of magnesia has the advantage that it prevents frothing and an excess does not affect the result. The distillation is carried out a t a temperature of 30’ under reduced pressure, and i t is necessary to continue the operation until two-thirds of the liquid has passed over. The distillation is facilitated by introducing a vertical con- denser and receiver between the vessel which contains the acid and the pump.With animal tissues, i t is necessary t o macerate thoroughly by grinding with fine sand, before the distillation is carried out. The amounts of oxygen absorbed when alkaline solutions of the following proteids-serum-albumin, serum-globulin, and oxyhaemo- globin from horses’ blood-are exposed to the atmosphere have been determined by the method previously described (Nencki and Sieber, J. pr. Chem., 1882, [ii], 26, 6). By CARLO MONTANARI (Chem. Centr., 1901, ii, 793-794 ; from Staa. sprim. agrar. ital., 1901, 34, 690-693).-The author applies Grandval and Lajoux’s method for estimating nitric acid in water or air to soils. Ten to 20 grams of the carefully selected sample are mixed with 100 C.C. of water and fre- quently shaken for some hours. Fifty C.C.of the filtrate are then shaken with 1-2 grams of purified animal charcoal and filtered, 10 or 20 C.C. of the filtrate are evaporated to dryness on the water-bath, and treated in the cold with a reagent made by dissolving 3 grams of crystallised phenol in 37 grams of sulphuric acid. After adding some water and bupersaturating with ammonia, the liquid is diluted t o 100,250,500, or in tbe author’s azotometer (Abstr., 1900, ii, 450). L. DE K. J. J. S.

G'asbel., 1901, 44, 548-552).- The gas is collected over brine in a gasometer and then burnt in a blowpipe burner supplied with oxygen. By means of an arrangement similar to that employed in the estimation of sulphur in illuminating gas, the products of combustion are drawn through two ten-bulb tubes containing water and an alkaline solution of bromine and connected with an empty Volhard tube, The phosphoric and sulphuric acids are then estimated as usual; a portion of the former deposits on the sides of the apparatus before it reaches the absorbing tubes and must be estimated separately. L. DE K. Simplification of Meineke-Woy's Method of Estimating Phosphoric Acid as Phosphomolybdic Oxide ; Precipita- tion of pure Ammonium Phosphomolybdate by Molybdate Solution containing Citric Acid ; Conversion of Wagner's Molybdate Magnesia Process into a purely Molybdate one.By ANTON SEYDA (Chem. Zeit., 1301, 25, 759--768).--The author has found by a series of experiments that the most accurate way of estimating phosphoric acid, including citrate-soluble acid, is its conver- sion into phosphomoly bdic oxide. The only possible objcction t o the process is the probable precipita- tion of free molybdic acid, particularly in the presence of a large excess of molybdate solution. This is, however, rarely the case when pre- cipitating in the cold and using a stirring apparatus for 15 minutes. If no citric acid is already present, an addition of 2 grams of it will prevent the precipitation of molybdic acid. Solutions containing no iron may be heated to 304 but those Containing it, not higher than 20' ; in this case, the liquid should be filtered 15 minutes after it ceases to be stirred.If the presence of free molybdic acid is suspected, the precipitate should be redissolved in dilute ammonia, mixed with 50-100 C.C. of dilute molybdate solution, and precipitated hot with nitric acid ; this operation may sometimes require repeating. (For the exact strength and proportions of the reagents, the original paper should be consulted.) The liquid may be filtered while still hot and the precipitate washed with a hot solution containing 5 per cent. of ammoilium nitrate and 1 per cent. of nitric acid. Alcohol of 95 per cent.should be used to rinse the precipitate from the sides of the porcelain Gooch crucible.

N. L.690 ABSTRACTS OF CHEMICAL PAPERS. Arsenic in Coal and Coke. By ALFRED C. CHAPMAN (AnaZyst, 1901, 26, 253-256).-A large quantity of the sample is finely powdered and well mixed; 0-5-2 grams are then carefully mixed with 2 grams of magnesium oxide and 0.5 gram of anhydrous sodium carbonate and introduced into a deep silver crucible.This is sup- ported in a slanting position and heated by a flame so as to keep the bottom at a dull red heat, the contents being occasionally stirred by means of a platinum wire. After about one hour, the oxidation is complete, but to make sure 0.5 gram of ammonium nitrate is added and a stronger heat applied for five minutes. When cold, the contents are transferred to a beaker, dissolved in dilute sulphuric acid, and heated to expel any nitric acid. This solution is then quantitatively tested for arsenic in the Marsh-Berzelius apparatus, the mirrors obtained being compared with standards. Tables are given showing the amount of arsenic found in coal, in the coke obtained therefrom, and also in the ashes.A small propor- tion of the arsenic is retained in the ash as ferric arsenate or calcium Method f o r the Destruction of Organic Matter applicable to the Detection of Inorganic Poisons, more especially Arsenic and Antimony~. By GEORGES DENIQ~S (J. Phawn.

CARNIELLI (Guxxetta, 1901, 31, i, 544--553).-The author has examined the various methods which have been proposed for the estimation of boric acid and draws the following conclusions from his results. The Berzeliu s-Stromeyer process of precipitation as potassium fluoborate is untrustworthy, especially when used for sodium compounds of boric acid.The Rosenbladt-Gooch method, depending on the ready volatility of ethyl borate, gives moderately concordant results when carefully carried out and when all the precautions suggested by Moissan (Abstr., 1893, ii, 435) are taken. Smith’s plan (Chem. News, 1882, 46, 286) of precipitating boric acid by means of manganous sulphate and determiriing the excess of the latter by titration with permanganate, gives good results when carried out according to the present author’s modification, which is as follows. Ten C.C. of a 4 per cent. borax solution are mixed with 20 C.C.of a 0.6 per cent. manganous sulphate solution and 30 C.C. of strong alcohol, the liquid being left in a covered beaker for half an hour and then filtered, the precipitate being washed with strong alcohol to remove all the manganous sulphate. The total filtrate is then evaporated to dryness on a water-bath, the residue dissolved in water, and the solution mixed with 7 C.C. of an 80 per cent. zinc sulphate solution and faintly acidified ; the liquid is then heated to boiling, poured into a measuring flask to which is also added a strong excess of standard permanganateANALYTICAL CHEIMISTRY. 691 solution, After making up to volume with distilled water, aliquot parts of the solution are titrated with decinormal oxalic acid t o determine the excess of permanganate.Thornson’s volumetric method (Abstr., 1894, ii, 28), in which the boric acid is set free and then titrated with standard alkali solution in presence of glycerol, using phenolphthalein as indicator, is rapid and accurate. The spectroscopic method proposed by Fohr (Zeit. anal. Chem. 1887, 26, 79) gives good results, but not for very small quantities of boric acid. T. H. P. Estimation of Carbon in Steel and Iron. By SCHMITZ (Chem. Zed., 1901,25, 684-6S5).-The steel borings are dissolved as usual in a mixture of dilute sulphuric acid, chromic acid, and copper sulphate in a special flask and the gases evolved are passed by means of a current of air over platinum spirals heated to redness. The carbon dioxide after being dried is then absorbed in the usual manner by soda- lime.L. DE K, Oxidation of Organic Nitrogen Compounds and the Estima- tion of the Carbon and Nitrogen therein by the Moist Pro- cess. By MISS E. VAN AKEN (Proc. K. Akccd. Wetensch. Amsterdam, 1901, 4, 91-95).-Using Fritsch’s method (Abstr., 1897, ii, 124) of simul- taneously estimating carbon and nitrogen in organic substances, the author finds that carbamide, dimethyl- and tetramethyl-carb- amide, acetylcarbamide, and thiocarbamide yield only half their nitrogen as ammonia. Cyclic nitrogen compounds, such as alloxan and malonureide, behave similarly j with uric acid and caffeine, the deficit is not so large. Oxamide, although giving more than half its nitrogen as ammonia, exhibits a much larger deficit than malonamide, succinamide, or asparagine.Fritsch appears to be incorrect in stating that his process is applicable to all nitrogen compounds which can be analysed by Kjeldahl’s method.

Estimation of Free Alkali in the Presence of Carbonate. By W. E. RIUENOUR (Chem. Centv., 1901, ii, 741 ; from J. PrankZin Inst., 1901, 152, 119--121).-According to Thompson, the liquid is first titrated with N-hydrochloric acid, using phenolphthalein as i d i - cator; this gives the free alkali and half ot the carbonate. After adding methyl-orange, the titration is continued, and the other half of the carbonate is thus estimated.The author has found that this is not strictly correct, and that the process may be improved by means of the following correction. To obtain the number of C.C. of N-hydrochloric acid which correspond with the carbonate con- tained in the mixture, the result of the methyl-orange titration should be multiplied by 2 and divided by the factor 104.5726.

Estimation of Calcium, Strontium, and Barium as the Oxal- ates. By CHARLES A.PETERS (Amer. J. Xci., 1901, [ iv], 12, 21 6--224).-Calcium oxalate is completely precipitated from a solu- tion containing an excess of ammonium oxalate, but the precipitate must not be washed too much, as it is appreciably soluble in pure water. Strontium oxalate is completely precipitated by ammonium oxalate from a solution containing 1/5 of its volume of 85 per cent. alcohol. The precipitation of barium oxalate is complete if the solu- tion contains 1/3 of its volume of 85 per cent. alcohol. Calcium, strontium, and barium oxalates, after decomposition with hydrochloric acid, may be accurately titrated with permanganate if some manganous salt be added. Strontium and barium oxalates (like calcium oxalate) are converted E.G. into carbonates by ignition, and ma\y be weighed in this form. I J. McC. Simple Reaction for distinguishing Aragonite and Calcite. By W. MEIGEN (Centr. Min., 1901, 577--578).--The finely powdered mineral is placed in a dilute solution of cobalt nitrate and this boiled for a few minutes. I n the presence of aragonite, there is a lilac-red precipitate of basic cobalt carbonate, whilst calcite remains white, or, in the presence of organic matter, becomes yellowish. Barium and strontium, but not magnesium, carbonates' give the same result as aragonite, and calcium phosphate produces a blue precipitate. This reaction is made use of for the purpose of distinguishing calcite and aragonite in various animal and vegetable secretions of calcium carbonate.L. J. S. Volumetric Estimation of Lead Dioxide in Red Lead. By MAX LIEBIG (Zeit. angew.

Comparison of the Quantitative Action of Reducing Agents on Mercury and Bismuth Salts. By THOMAS TYRER and CHAS. T. TYRER (Pharm. 2, 1901, [iv], 13, 144).-A comparison of a modi- fication of the method for the estimation of mercury by reduction with hypophosphorous ‘acid described by Bennett (this vol., ii, 131) with other reduction methods.Stannous chloride gives low results owing to the loss occasioned by the fine state of division of the mercury. With formaldehyde in alkaline solution, the same difficulty occurs, whilst in acid solution the reduction is incomplete. Phenylhydrazine in alkaline solution pro- duces only partial precipitation, and in mid solution no reduction takes place. With sodium arsenite in acid solution, reduction is slow and incomplete, but in presence of an alkali, complete reduction occurs ; the results, however, are somewhat lower than those obtained by the hypo- phosphorous acid method. A strongly alkaline solution of potassium antimony tartrate effects complete reduction, but the product is con- taminated with traces of an antimony salt.By boiling solutions of mercury salts with phosphorous acid in large excess, fair results are obtained. A modification of the method of Vanino and Treubert (Abstr., 1897, ii, 601), in which hypophosphorous acid is used in pre- sence of hydrogen peroxide, is also found t o be satisfactory. Estimations of bismuth salts were made with hypophosphorous acid and with formaldehyde, but although good results were obtained, neither process has any advantage over the sulphide method. E. G. Estimation of Metallic Iron in reduced Iron. By ALBERT MARQUARDT (Chew.

The mixture is allowed to stand for an hour, being thoroughly shaken every 10 minutes. The solution is then diluted t o 100 C.C. and the excess of iodine titrated according to the earlier Formation of Carbon during the Electrolysis of Ammon- ium Oxalate. By HANS VERWER (Chem. Zeit., 1901, 25, 793-’793).-Avery and Dales (Abstr., 1899, ii, 814) have stated that iron depmi ted by electrolysis from a solution containing ammonium oxalate contains carbon. The author finds that such is the fact, particularly when 8 high tension current is used. Tn any case, however, no separation of carbon takes place until the greater portion of the iron has been deposited.It also appears that carbon is not deposited directly from the oxalate, but from t h e ammonium carbonate or ammon- ium hydrogen carbonate, which results from the electrolytic decomposi- tion of the oxalate. On dissolving the iron, an odour of hydrocarbons is noticed, showing that the carbon, partially at least, is in a state of directions. L. DE K- combination with the iron. L.

E. G. Precipitation of Tin from its Sulpho-salts and its Separation from Antimony by Electrolysis. By HERMANN OST and W. KLAPPROTH (Zeit. angew. Chem., 1901, 14, 817-827).-The authors have continued their researches on the electrolytic deposition of tin and antimony, using a cell with a diaphragm (Abstr., 1900, ii, 692), and communicate the results in eight tables. Several illustrations are also given, one being of a modification of the former apparatus. The separation of tin and antimony is finally recommended to be carried out as follows :-The mixed sulphides, obtained in due course, and containing at most 0.5 gram of total metal, are dissolved in as little sodium sulphide as possible and the solution is diluted to a definite bulk.I n one-half of the liquid- the antimony alone is estimated by adding 8 grams of sodium sulphide and water up to 80-96 c.c., and using a current of 0.1-0.2 ampere in the cold for 7 hours. I n the other portion, both tin and antimony are precipitated by adding sufficient ammonium sulphate to convert all the sodium sulphide into the ammonium compound. I n addition, 40 grams of sodium sulphate are added, also 10 C.C. (= 2 grams) of ammonium sulphide. After diluting to 80-90 c.c., the liquid is electrolysed by a current of 0.3-0.5 ampere.After two hours, the precipitation is generally com- plete. The cathode with the sulphur precipitate is then taken from the first cell, placed in another cell containing 25 grams of sodium sulphate in 125 c.c., and a cutrent of 05-1 ampere continued for an occupies a longer time.

The ore is tieated with aqua regia and the solution evaporated t o dryness, the residue dissolved in water, treated with sodium nitrite and carbonate to remove iron, lead, &c., and distilled in a current of chlorine t o remove osmium and ruthenium.The liquid is then neutralised by hydrochloric acid, and the rhodium and iridium pre- cipitated by means of sodium nitrite and potassium chloride. The plat.inum and palladium nitrites remaining in solution are converted into chlorides by evaporation with hydrochloric acid, and the metals pre- cipitated by heating with formaldehyde in alkaline solution, heated in hydrogen, dissolved in aqua regia, the palladium chloride reduced by696 ABSTRACTS OF CHEMICAL PAPERS, nitric oxide, and the platinum precipitated by ammonium chloride. Iridium is best estimated in another portion of the liquid from which osmium and ruthenium have been removed in the manner previously Ry LUDWIG W.WINKLER (Zeit. anal. Chem., 1901, 40, 523-533).-The total carbon dioxide is estimated as follows : In a 250 C.C. flask with a neck 5-6 mm. in diameter, and with a piece of black caoutchouc tube slipped over the neck, 50 c,c. of dilute hydrochloric acid are boiled until all air is expelled. The caoutchouc tabe is closed with a clamp, and the exhausted flask cooled and weighed. The neck is then connected with a bent tube dipping into the water to be examined, and on opening the clamp a quantity of the water is drawn into the flask. The amount is found by reweighing the flask; a delivery tube is ad- justed and the carbon dioxide is boiled out, coliected over mercury, and measured. To ascertain how much of i t is in combination with bases, the water is titrated with X/10 acid and methyl-orange.Disso1ved:oxygen and nitrogen may be expelled from a natural water by filling completely with the water a 500 c c. iiask, a t the bottom of which lies 10 grams of calcite (in fragments free from dust) and adding 20 C.C. of hydrochloric acid (sp. gr. 1.19). If this is done skilEully, a rubber stopper carrying an evolution tube can be adjusted before any gas is evolved. The oxygen and nitrogen are completely expelled in 15-20 minutes. The gases are collected in a burette over sodium hydroxide solution, and measured after replacing this with pure water. The oxygen is then absorbed by alkaline pyrogallol introduced through the stopcock of the burette. Neutral-red as a means of detecting Bacillus Coli in Water.By R. H. MAKG~LL (J.

An important factor is the behaviour of the distillate towards LJT/lOO potassium permanganate. The free and total acidity are taken in the usual manner and the combined acidity is found by difference. I n one instance, 100 C.C. of the sample required 0.0672 gram of potassium hydroxide to neutralise the free acid, and 0,0266 gram for the combined acid. When testing diluted commercial alcohol, it will be found that it is the combined acid which exceeds the free.The following proportion between combined and total acidity has been observed. I n the case of marc brandy i t varies from 1 : 1.25 minimum to 3 : 5.2 maximum; for plum brandy from 1 : 4 to 1 : 8.4; for diluted alcohol from 1 : 1.3 to 1 : 1.75. If 1 C.C. of N/100 permanganate is added to 1 c,c. of the distillate contained in a 50 C.C. stoppered cylinder, it will be noticed that the brandies are more quickly oxidised than the spirit. When the mixture ha6 turned yellowish-brown, the marc brandy and the spirit both smell of aldehyde, whilst the plum brandy has the characteristic odour of plum stones. On adding another C.C. of permanganate and waiting until the mixture has again turned yellow, the marc brandy smells of ethyl heptoate, the plum brandy has retained its odour, and the spirit has nearly lost its aldehydic odour and smells faintly of acetic By MANSEAU (Rev.Intern.

Cents’., 1901, 25, 709-710; from Deut. sned. Woch., 1901, 27, 440--442).-The yellow precipitate or colora- tion often noticed when testing for dextrose with copper sulphate and aqueous sodium hydroxide is not necessarily due to the presence of creatinine, as i t may be also caused by a 4 per cent.solution of sarco- lactic acid, a 1 per cent. solution of allantoin, a 2 per cent. solution of lactic acid or asparagine, or a strong solution of isobutyric acid, benzoic acid, or thymol. The presence of an equal bulk of alcohol has also the same effect. With the exception of creatinine, these substances only interfere when present in large quantities, and on adding more alkali the yellow colour changes to red. The ‘‘ yellow Trommer reaction ” is therefore a characteristic test for creatinine. A 0.1 per cent. solution of p a n - idine carbonate in a 1 per cent. solution of sugar (? dextrose) also gives the yellow reaction if excess of alkali be avoided; a 0.1 per cent. solution of glycocyamine also gives the reaction ; weaker solutions do Estimation of Lactose in Milk.By C.

After evaporating and drying at 50°, the contents are weighed and then transferred t o a silver crucible and examined for sulphur in the manner first described. The weight of the residue less the sulphur represents the substances soluble in chloroform in the original sample except nitroglycerol, moisture, and sulphur, The percentages of the former substances plus the moisture and sulphur in the original sample deducted from the total matter soluble in chloroform are equal to the percentage of nitroglycerol. In another portion, the residue in the platinum dish may be examined for resins, paraffin, &c.Use of Lunge’s nitrometer.-This is best standardised by the ‘( em- pirical method.” Nitric oxide, derived from a known amount of pure potassium nitrate, is passed into the measuring tube and the quantity of air in the reduction tube is then varied until the volume of the nitric oxide is approximately the calculated amount. The reduction tube is now sealed, a series of tests made with slightly varying amounts of potassium nitrate, and in each case a cor- rection factor determined which shows 100 per cent.in purity in the 5 0-2700 ABSTRACTS OF CHEMICAL PAPERS. nitrate taken. A sample of pure dry nitroglycerol may also be used. The extreme variations in the determinations should not exceed 0.05 per cent. From the average of the determinations, a correction factor is obtained, which is then applied to all determinations. The sulphuric acid best suited for nitrometer work contains 94-95 per cent. of acid. L. DE K. Estimation of Glycogen. By ALFONS BUJARD (Zeit. Nuhr.- Genussm., 1901, 4, 781).---Lebbin’s process (this vol., ii, 45) is not based on a new principle, as the author since 1897 has made use of alcoholic potash t o separate proteids from glycogen in the following way.The meat is dissolved in 8 per cent. alcoholic potaeh, diluted with 50 per cent. alcohol and the insoluble residue well washed with the latter. The crude glycogen is then dissolved in 8 per cent. aqueous potash, filtered, faintly acidified with acetic acid, and precipitated with alcohol. The precipitate requires no further purification. L. DE K. Occurrence and Estimation of Lactic Acid in Wines. By RUDOLF KUNZ (Zeit. Nuhr.-Genussm., 1901, 4, 673-683).-Two hundred C.C. of wine are mixed with a slight excess of powdered barium hydroxide and evaporated to about two-thirds of the original volume. When cold, the whole is rinsed into a 200 C.C. flask, which is then filled up t o the mark; 150 C.C. of the filtrate are evaporated to a thin syrup after neutralking the excess of baryta with carbon dioxide, and when cold, excess of dilute sulphuric acid is added, and the whole intro- duced into a Schacherl extraction apparatus where the liquid is extracted with ether for 18 hours.The ether in the extraction flask is now driven off by warming after 30 C.C. of water have first been introduced. The aqueous solution is then distilled in a current of steam until all the volatile acids have passed over and the residue, after adding a few drops of phenolphthalein, is mixed with a slight excess of barium hydroxide. If after 15 minutes’ warming on the water-bath the alkaline reaction is still persistent, a current of carbon dioxide is passed and the a t r a t e concentrated to 10 C.C. After intro- ducing this into a 150 C.C. flask and using 40 C.C.of water for rinsing, the liquid is made up t o the mark by adding 95 per cent. alcohol. One hundred C.C. of the filtrate are evaporated on the water-bath, and the residue is rinsed into a beaker, acidified with hydrochloric acid, and precipitated with sodium sulphate. From the weight of the barium sulphate, the corresponding amount of lactic acid contained in 100 C.C. of wine is readily Calculated. Experiments are communicated in support of the method and to prove that the lactic acid extracted from wines is really the pure substance. A table is given containing the amount of total acidity Calculated as tartaric acid, potassium hydrogen tartrate, tartaric acid, volatile acids calculated as acetic acid, succinic acid, lactic acid, amount, of C.C. of N / 2 alkali used for neutralking 100 C.C.of wine, amount of alkali corresponding with the acids determined and alkali consumed by un- determined acids. Twenty-three samples were tested in this way, the lactic acid varying from 0.1185 to 0.4360 gram in 100 C.C. L. DE K.AN ALP TICAL CREMISTRY. 701 Estimation of P-Hydroxybutyric Aaid in Urine. By PETER BERGELL ( Z e d . physiol. Cham., 1901, 33, 310-31 l).-The estimation of P-hydroxybutyric acid in urine may be accomplished much more readily if in the Magnus-Levy method (Amh. exp. Path. Plbarm., 46, 390) the dried residue from the urine is extracted with ether in a Soxhlet apparatus instead of the urine itself being extracted by shaking with ether. To obtain the dried residue, 100-300 C.C. of urine are rendered slightly alkaline with sodium carbonate and evaporated to a syrup; this is cooled, and mixed with syrupy phos- phoric acid, then with 20-30 grams of finely divided and ignited copper sulphate and 20-25 grams of fine sand.Detection of Citric Acid in Wine. By MATTEO SPICA (Gazzettcc, 1901, 31, ii, 61--67).-0ne hundred C.C. of the wine are evaporated on the water-bath to a syrup which is extracted repeatedly with small quantities of alcohol, the liquid being filtered through a dry filter and alcoholic potassium hydroxide added in such quantity as to leave the solution faintly acid. After a few minutes, the liquid is filtered to remove the separated potassium tartrate, and then exactly neutralised with alcoholic potassium hydroxide. If citric acid is present, a white precipitate, consisting of potassium citrate and potassium hydrogen tartrate, is formed and is filtered, dried, and heated gentlyin a dry test-tube with a very small quantity of sulphuric acid until bubbles of gas are evolved.After cooling and diluting with water, the liquid is rendered alkaline with potassium hyilroxide, the mixture being kept cold. I f citric acid was present in the wine taken, the liquid now obtained contains small quantities of acetone, and on adding sodium nitroprusside, a blood-red coloration is formed, which changes to reddish-violet on adding acetic acid. I n case the wine contains no citric acid, the addition of the sodium nitroprusside causes the form- ation of a yelJomish-green coloration, due to the presence of tartaric acid. T.H. P. J. J. S. Detection and Estimation of small quantities of Salicylic Acid in Wines and Foods. By HENRI PELLET (Ann. Chim. arzaE. appZ.? 1901, 6, 327--328).--Two hundred C.C. of the wine are rendered alkalino and concentrated to, say, one-tenth, and the liquid is then treated by the method proposed by the author and Grobert. In this manner, 0.01 gram of salicylic acid in 100 litres of wine may be detected and estimated. The extraction with ether is always attended with loss, the amount of which must be ascertained by testing pure samples to which a known quantity of salicylic acid has been purposely added (see follow- Nature of the Substance giving the Ferric Chloride Re- action ; Presence of Salicylic Acid in Pure Wines. By HENRI PELLET (Ann.

BURGESS (Analyst, 1901, 26, 260-262).-The author has been able t o procure an undoubtedly genuine specimen of oil of citron or I' essence de cedrat." The corn- mercial article is generally oil of lemon, '' essence de citron," with some verbena, The analysis differs considerably from those obtained by other workers, as will be seen by referring to the table in the original paper.(100 mm.) + 80'13'. On distilling the oil at a pressure of 10 mm., three fractions were obtained. No. 1, b. p. 60-62', constituting 12 per cent. of the sample, h d a rotation of + 86'30' ; No. 2, b. p. 62-64', amounting to 80 per cent., a retation of +85O30'; and No. 3, b. p. 64-45', amounting to 5 per cent., a rotation of + 13'30'. Nos. 1 and 2 were refractionated over sodium, and the main fraction was identified as limonene, b. p. 173-174' under atmospheric pressure.No. 3 was proved to consist of citral. This was also determined in the original sample by the sodium hydrogen sulphite and the hydroxylamine methods, which showed respectively 6.2-5-8 and 5.7 per cent. of citral. A crystalline deposit purified by chloroform, light petroleum, and recrystallisation from alcohol gave on analysis figures corresponding with those required for the formnla C,,H,,O, ; this substance is probably the same as that observed by Crismer and more recently by Theulier.

This is more especially the case with old samples, and it may, perhaps, be possible to discriminate between fresh and stored foods by determining the acidity by the two methods. By FERNAND RANWEZ (Rev. Intern. PalsaJk., 1901, 14, 89-94).-A critical examination of some processes recommended of late for the detection of cocoanut oil in butter. Of these the only one likely to be of service is the process proposed by Vandam (Ann.Pharm., 1901, 201), based on the fact that cocoanut oil contains a large proportion of volatile acids which are insoluble in water but soluble in rectified spirit, The process N.

To .apply this to chocolate, 20-25 grams of the sample are boiled for 5. minutes with 50 C.C. of ether, and after a short time has elapsed the filtrate is evaporated to dryness and the residual fat heated for some hours t o 95" in order to separate the colouring matter.The fat is then filtered whilst hot, and 5-6 grams of the clear liquid are shaken with an equal volume of a solution of sugar in hydrochloric acid. In the presence of sesamd oil, the characteristic magenta coloration makes its appearance. L. DE K. Estimation of Formaldehyde. By A. G. CRAIG (J. Amer. Chem. Xoc., 1901, 23, 638--643).-Several methods are criticised, Legler's process being finally preferred. This process, with a slight modifica- tion introduced by the author, is asfollows. A quantity of the sample representing about 0.5 gram of pure formaldehyde is placed in a 3 OZ. pressure bottle fitted with a soft rubber stopper, and 25 C.C. of approxi- mately normal ammonia are added; in a similar bottle, 25 C.C. of normal ammonia only are introduced.Both are then placed up to the neck in a bath of boiling water for one hour and when cold they are carefully t i trated with normal sulphuric acid, using methyl-orange as indicator. The difference between the determinations represents By ZDENBK PE~KA (Chem,, Zeit., 1901, 25, 743).-Legler's ammonia process gives good results if the excess of ammonia is carefully titrated, using litmus as indicator, the end reaction being observed by noticing the disappearance of the blue colour without getting the so-called neutral colour. Romijn's iodometric process (Abstr., 1987, ii, 166), oxidation of formaldehyde to formic acid in alkaline solution, is said to be the most satisfactory method and preferable to the one proposed by Blank and By OSKAR BLANK and HERMANN FINKENBEINER (Chem.Zeit., 1901, 25,794).-The authors call attention to their method of estimating formaldehyde by means of hydrogen peroxide (Abstr., 1899, ii, 188, S20). The resiilts agree well with those o1,t:iined by the iodometric methad, and the process is easy of execution.

Compare this vol., ii, 135)-If the colour produced with ferric chloride should be a dirty brown, the liquid is acidified and again shaken with ether-petroleum mixture ; this is then shaken three times with 20 C.C.of water and evaporated to dryness, when the test with ferric chloride is again applied. I f there still exists a doubt, another experiment should be made as follows : 200 C.C. of wine are mixed with 40-50 drops af a 10 per cent. solution of ferric chloride and then digested on the water-bath with a slight excess of freshly preci- pitated calcium carbonate. The filtrate, which is now free from tannins, is tested as described ; 0.5 milligram of “ saccharin ” may thus be detected. L. DE K. Detection of “Saccharin” by means of New Reactions. By MATTEO SPICA (Gacxxeita, 1901,31, ii, 41--46).-The author has devised two methods for the detection of small proportions of ‘ saccharin ’ in commercial products. The first of these consists in converting the imino-group of the ‘ saccharin ’ into nitric acid, which is recognised by means of diphenylamine hydrochloride, whilst in the second method the ‘ saccharin ’ is transformed into one of the sulphaminobenzoic acids which can be detected by the diazo-reaction.The method of working is as follows. The liquid to be tested, acidified with sulphuric acid, or in the case of a solid, the extract obtained with the dilute acid, is shaken in a separating funnel with ether or a mixture of ether and light, petroleum, the liquid being then filtered and divided amongst three dry test-tubes which are placed in a water-bath to evaporate. The residue in one tube is tested for salicylic acid by adding nitric acid and heating gently to form picric acid, which is recognised by the method previously described (Abstr., 1895, ii, 426).To the second residue is added a little lime, best somewhat granular as obtained from powdered marble, and the mixture then heated until i t becomes slightly brown; a few C.C. of water aro then added, the liquid heated to boiling, and the clear solution decanted off into another tube, where i t is mixed with a few drops of hydrochloric acid and a small piece of zinc; after hydrogen has been evolved for 20 minutes, the liquid is again decanted off and to i t are added a few drops of dilute sodium or potassium nitrite solution and 5 to 6 drops of a-naphthylamine hydrochloride solution ; in the event of ‘ saccharin ’ being present in the substance examined, a crimson coloration is obtained which only appears after some hours if the quantity of ‘ saccharin ’ is very small.To the residue in the third tube are added a few drops of pure sulphuric acid and a crystal of potassium permanganate, oxidation being started by gentle heating, and the excess of permanganate removed by means of oxalic acid or sulphur dioxide. The liquid is then diluted with a few C.C. of water, a few drops of diphenylamine hydrochloride are added, and pure sulph- uric acid poured carefully down the side of the test-tube so as to form a distinct layer at the bottom. The presence of nitric acid,ANALYTICAL CHEMISTRY. 705 produced from ‘ saccharin,’ is manifested by an azure-blue ring in the layer between the sulphuric acid and the aqueous liquid. T. H. P. Estimation of Urea in Urine. By JOHN H. LONG (J: Amw. Chem.Soc , 1901,23, 632--638).-1n order to obtain exact results with Liebig’s mercuric nitrate process, allowance should be made, not only for the presence of sodium chloride, but also for the ammonia, uric acid, and creatinine. By careful analyses, the author has found that the average error due to smmoiiia is 1 C.C. of the mercury solution when titrating 10 C.C. of urine; uric acid is responsibie for 0.15, and creatinine for 0.85 C.C. ; total, 2 C.C. of mercury solution to be deducted. These figures apply only to fresh urine. L. DE K. General Reaction of the Aromatic Amines and Hydrazines with Wood. By ERCOLE COVELLI (Chern. Zed., 1901, 25, 684).- Amines.-It is known that aniline gives a yellow coloration with fir wood. The author states that ail aromatic amines give a’reaction.The test is best applied by dissolving traces of the amines in hydrochloric acid, and moistening a shaving of fir wood. Aniline, methylaniline, o-toluidine, and p-toluidine cause a yellow colour resembling that of arsenic trisulphide. Sulphauilic acid, 0-, rn-, and p chloroaniline, o- and paminophenol, phenetidine, orthoform, aminosdicylic acid, diphenyl- amine, m-phenylenedinmine, a-naphthylamine, and 0- and p-aminobeuzoic acids cause an orange-yellow colour ; o- and m-nitroaniline, diwmino- phenol, triaminophenol, pnitroaniline, and p-phenylenediamine give an orange-red colour. When acid-groups are introduced (ncetanilide, lactophenine, &c.), the wood is no longer coloured. Smmonia removes the colour. Hydrazims.- A solution of phenylhydrazine in hydrochloric acid gives with fir wood a yellow colour which turns red and finally green after a few hours; on adding :ammonia, it changes again to red, but becomes green on adding acid.This is a very characteristic reaction for phenylhydrazine. p-Tolylhydrazine and a-naphthylhydrazine first give a yellow and then a red colour which turns brownish after some hours. The active substance contained in the wood is oxidised by chlorine water ; if a piece of paper containing wood-pulp is immersed for 24 hours in chlorine water, i t loses its property of reacting with amino- compounds. Pyrrole, indole, and carbazole give with wood a reddish colour which disappears on moistening with ammonia. L. DE K. Formation of Carbamide by the Oxidation of Physiological Nitrogenous Substances by means of Permanganate in Acid Solution.By W. FALTA (Bev., 1901,34, 2674--2679).-The method adopted by Jolles (Abstr., 1900, ii, 636) for the oxidation of nitro- genous substances, according to which the acid solution is boiled for 10 hours and then evaporated, itself leads to the decomposition of the greater part of any carbamide present or produced in the liquid. Hipp- uric acid and asparagine do not yield carbamide when oxidised by permanganate in acid solution, and the substance obtained by Jolles as a product of their oxidation, and believed by him to be carbamide706 ABSTRACTS OF CHEMICAL PAPERS. oxalate, is, in reality, a mixture containing ammonium salts and com- pounds of manganese. Uric acid yields a certain proportion of carb- amide, along with a considerable proportion of ammonia.Behaviour of Acid Aqueous Solutions of Alkaloids [Gtlucos- ides, &c.] towards different Solvents. By HANS PROELSS (Chem. Centr., 1901, 11, 236-237 ; from Apoth. Zeit., 16, 434-435).-The following solvents were tried : ether, chloroform, ethyl acetate, benzene, and mixtures of ether or alcohol with chloroform. Of alkaloids, bc., the following were tested, 5 C.C. of an aqueous solution (1 in 500) being used. Digitalin, colchicine, picrotoxin, brucine, veratrine, strychnine, atropine, codeine, and morphine. To render the liquid acid, a few drops of dilute hydrochloric acid were added, and alkalinity was imparted by means of sodium carbonate or ammonia. It was shown that chloro- form is the best general solvent.Sodium carbonate and ammonia may be used for brucine, strychnine, atropine, and codeine; ammonia should be used for veratrine and morphine. Colchicine is readily ex- tracted from an acid solution by chloroform ; digitalin from an acid solution by chloroform or chloroform-ether mixture ; picrotoxin from an acid solution by ether-chloroform, alcohol-chloroform, or benzene ; brucine from an alkaline solution by ether-chloroform ; veratrine from a solution mixed with sodium carbonate by ether-chloroform, alcohol- chloroform, chloroform, or ethyl acetate, and from an ammoniacal solution by ether or benzene ; strychnine from an alkaline solution by chloroform, alcohol-chloroform, or benzene ; atropine from an alkaline solution by chloroform, alcohol-chloroform, ether-chloroform, or benzene ; codeine from an alkaline solution by alcohol-chloroform, benzene, or ethyl acetate ; morphine from an ammoniacal solution by ethyl acetate, and from a solution containing potassium hydrogen car- bonate by alcohol-chloroform.Emulsions are mostly formed when benzene is used, and more rarely when ether or ethyl acetate is em- Resisting Power of Alkaloids, Glucosides, and Bitters to Putrefaction. By HANS PROELSS (Chem. Centr., 1901, ii, 503; from Apoth.

After four months and a half, the box was unearthed, the contents of each glass vessel were well mixed, and 100 grams of the material were used in the testing. The following poisons were sharply detected : strychnine, brucine, codeine, colcbicine, veratrine ; feebly : picrotoxin, digi talin, opium alkaloids, morphine ; atropine couId not be detected. After being again buried forthree months and a half, another 200 grams were tested, and colchicine, brucine, veratrine, strychnine, codeine, and morphine could still be detected. Strychnine and brucine may be tested for in each other’s presence, but not strychnine and morphine.That the morphine was so stable may be explained by the fact that A. H. ployed. L.

L. DE K. Estimation of Aconitine in Preparations of Aconite. By H. ECALLE (J. Phavm. Chim., 1901, [vi], 14, 97-102).-Bertrand (Abstr., 1899, ii, 456) has stated that when silicotungstic acid is added t o a solution of aconitine, a precipitate is obtained of the composition 12 W0,,Si0,,2H20,4A,nH,0, where A i s the alkaloid. The author finds that this precipitate is better represented by the formula 12 W0,,Si02,2H,0,3~A,nH20.I n order to estimate the aconitine in extract of aconite, excess of ammonia is added to a solution of the extract in dilute nitric acid, and the alkaloid removed by shaking repeatedly with ether. The ethereal solution is shaken with dilute nitric acid, the acid solution warmed to expel dissolved ether, and, when cold, treated with a solution of silicotungstic acid. The mixture is heated until i t boils, and left for 24 hours; the precipitate is then collected, washed, dried, and ignited. The weight of the alkaloid is obtained by multiplying the weight of the residue, 12WO,,SiO,, by 0.793. Estimations of the alkaloid in different commercial specimens of tincture and extract of aconite show that the amount is liable to great variation.Microchemical Reaction for Atropine. By N.

The alkaloid is heated with a drop of aqueous sodium hydroxide, and the vapours are condensed on a n object glass. A little hydrochloric acid is added, the liquid is evaporated, the residue dissolved in a drop of water, and a small particle of potassium iodide added, The tropine hydriodide thus Extraction of Morphine with Immiscible Solvents. By WILLIAM A. PUCKNER (J. Amer. Chem. Xoc., 1901, 23, 470-473).--8 large number of experiments are communicated showing t h a t morphine may be removed from a very slightly amrnoniacal solution by repeated agitation with an equal volume of a mixture of 80 volumes of chloro- form and 20 volumes of alcohol.If a somewhat large excess of am- monia is present, this may be neutralised by addition of sodium hydrogen carbonate. Addition of ammonium chloride is unnecessary. A solution of morphine in the slightest possible excess of sodium hydroxide yields only a little alkaloid to the alcohol-chloroform mixture, and in the presence of more alkali scarcely any of the alkaloid is extracted ; on adding sodium hydrogen carbonate, the morphine is, however, liberated and rendered soluble (compare Wirthle, this vol., Estimation of Morphine in Opium by means of Ammonia- cal Silver Chloride.

A definite weight of opium powder is treated with 10-20 times its weight of boiling water and the mixture is frequently stirred for an hour. The liquid is filtered and the insoluble matter washed with hot water. To the united filtrates is now added a solution of silver chloride in ammonia and the whole is at first gently heated, although this is not strictly necessary. After a few hours, the precipitation is complete and the reduced silver is then collected on a filter and washed until the filtrate is no longer affected by ammonium sulphide.The filter is dried at 130°, burnt in a porcelain crucible, and the metallic silver weighed.

Five grams of the powder are extracted with hot water and when cold diluted t o 500 c.c., or they ase mixed with 500 C.C. of water and digested for 48 hours. Ten C.C. of the clear solution are then withdrawn and diluted to 400 C.C. ; 10 C.C. of dilute sulphuric acid and 20 C.C. of solution of indigo-carmine are added, and the liquid titrated with N/20 potassium permanganate. I n the meanwhile, 20 C.C. of the filtered solution are mixed with 10 C.C. of ammoniacal copper solution (22 grams of copper sulphate dissolved in 1 litre of ammonia ; 1 C.C.precipitates 0.014 gram of tannin) and diluted to 200 C.C. One hundred C.C. of the filtrate are then diluted to 400 C.C. and titrated as before; the difference in C.C. of permanganate between the two titrations multiplied by 2.078 represents the percent- age of tannin in the sumach.

To 10 C.C. of the liquid are added about 5-10 C.C. of a potassium plumbite solution of sp. gr. 1.20, the solution being then either repeatedly shaken to aerate it or mixed with a few centigrams of potassium persulphate and finally made up to 100 C.C.At the same time, 10 C.C. of a solution of 1 part of gallic acid in 1000 are treatediiin the same way. Ten C.C. of each of the two solutions are poured into the cells of a Sallerou colorirneter and corn- pared. If the coloration is the same in the two cases, equal quantities of gallic acid are present in the two solutions. If this is not the case, water is added from a burette to the liquid which is the more intensely coloured until i t has the same density of colour as the other. On reading off the amount of water added, the calculation of the percentage of gallic acid in the material taken can be readily carried out. The numbers obtained by this method are lower than those yielded by the permanganate method usually employed.T. H. P. Estimation of Humus in Soil. By KURT BIELER and K. As6 (BuZl. ColZ. A y . . Tokyo Imp. Univ., 1901, 4, 237-240).--Humus was determined by four different methods, (1) by combustion and multiply- ing the carbon result by 0.471, (2) by Knop’s method, (3) by extracting successively with dilute hydrogen chloride and 3 per cent. ammonia and deducting the weight, of ash from that of the ammonia residue, and (4) by Aschmann and Faber’s volumetric method (Abstr., 1900, ii, 60). The following amounts of humus were found bv the differint methods : (1) f3-84, (2) 8.85, (3) 9.79, and (4) 6.95 pe; cent. N. H. J. M. The Bromination and Iodination Numbers of Proteids. By WILRELM VAUBEL (Zeit. anaZ. Chem., 1901, 40, 470--P74).-1t has been shown by Bluni and Vaubel (Abstr., 1898, i, 287,609) that when albumin, casein, &c., are treated with halogens, a larger quantity of the haloid acid is obtained than corresponds with the halogen which replaces hydrogen in the proteid. They therefore distinguish between the bromine (or iodine) number, and the bromination (or iodination) number, the latter being the total amount of halogen consumed, and being more easily ascertained than the former.I n neither case does a single treatment complete the substitution, but for comparable results a single treatment is sufficient. With bromine, the action pro- ceeds much further than with iodine. The process employed consisted in dissolving 2 grams of the proteid in 200 C.C. of water, adding sodium bromide, 200 C.C. of glacial acetic acid, and 20 C.C.of hydro- chloric acid, and then bromate solution until an excess, persisting for 15 minutes, was shown by iodide-starch paper. Allowing 9 per cent. for the bromine consumed in substitution, the three proteids showed a, further consumption, namely, egg-albumin, 35.04 ; blood albumin, 40.76 ; and casein, 27-00 parts of bromine per cent. M. J. S.710 ABSTRACTS OF CHEMICAL PAPERS, Detection of Minute Traces of Albumin in Urine. By A. PRAUM (Chem. Centr., 1901, ii, 323; from Deutscli. med. Zeit., 27, 220). -A few C.C. of the filtered urine are mixed with a few drops of a con- centrated solution of sulphosalicylic acid, and a little more of the filtered urine is carefully poured down the sides of the test-tube. Operating in this manner, any difference in the turbidity oE the two By G.ROCH (Chem. Centr., 1901, ii, 4 4 5 ; from Pharm. Centr.-HaZZe, 42, 393).- This reagent, recently recommended by Praum (preceding abstract), has been used for a long time by the author (Pliarm. Centr.-HccZle, 30,549). It is best prepared by warming 13 grams of salicylic acid with 20 grams of sulphuric acid and dissolving the product in 67 grams of water; the slight excess of sulphuric acid does not affect the result. By means of this test, as little as 0.0025 per cent. of albumin may be Detection of Peptone in Urine and Faxes. By 0. FREUND Chern. Centr., 1901, ii, 5 0 5 ; from Centr. inn. Med., 22, 647-651)- When testing for peptones in urine, it is necessary to completely remove urobilin. According to the author, this may be satisfactorily effected by adding t o 10 C.C.of urine 2 or 3 drops of 20 per cent. acetic acid, 5 C.C. of 20 per cent. solution of lead acetate or basic lead acetate, boiling, and filtering. To the filtrate is then added aqueous potassium hydroxide so long as this produces a precipitate, and the liquid is again boiled and filtered. The filtrate may now be used for the biuret test. The pre- sence of urobilinogen does not interfere; this may, moreover, be converted into urobilin by means of iodine or nitrous acid, and then Pancreatic Rennin and Diastase, By HORACE M. VERNON (J. YhysioZ., 1901, 27, 174--199).-The rennin ferment in pancreatic extracts is estimated by determining the time of onset of Roberts’ ‘ metacasein reaction, ’ and the diastatic by the time required for starch solution to reach the ‘achromic point ’ when tested with iodine, The metacasein reaction depends on the rennin, not on the trypsin in the extract ; it bears no relation to tho tryptic power of the extract, but there is a fairly constant relationship between it and the milk curdling capacity of the extracts.The time of onset of the two reactions mentioned varies inversely as the one-sixth power of the amount of ferment present. This proportion is, however, upset by the addition of 0.1 per cent. of sodium chloride, or by the use of tap water instead of distilled water in making the solutions of starch. The diastatic activity is increased by small quantities of acid, but is inhibited by 0.009 per cent. of hydrochloric, 0.04 per cent. of lactic, and 0.16 per cent.of acetic acid. Extracts kept for several hours a t 38’ undergo loss of power on milk. The rate of destruction varies with the activity of the original solution, Hence it is concluded that rennin, like trypsin, is not a single chemical substance. The diastatic ferment is destroyed at the same rate what- ever its initial activity. layers will be readily noticed. L. DE K. Sulphosalicylic Acid as a Test for Albumin. detected in urine. L. DE K.

By JULIUS FORM~NEK (Zeit. anal. Chem., 1901, 40, 505--523).--The position of the bands in the absorption spectra of the blood colouring matters is indicated in the present paper by the wave-length corre- sponding with the maximum darkness, which is not dependent (as the positions of the edges of the bands are) on the concentration of the solution or the thickness of the layer.Blood, simply freed from fibrin and suitably diluted, gives the two bands of oxghzemoglobin a t X 578.1 and X 541.7. After standing for some days exposed to air and light, a new band at, X 634, due to methsmo- globin, becomes visible : the m o u n t of the latter substance increases with time and a feeble band a t X 500.8 is developed. I f yellow ammon- ium sulphide or Stoke's reagent is added to the diluted blood, haemoglobin is produced, which gives one broad band a t X 554.7 and sometimes a feeble one at h 619.8 due to sulphohaemoglobin.When a dilute acid is added t o blood the oxyhaemoglobin splits into albumin and acid hsmatin. The latter gives three bands, at X 554.8, 517.7, and 654.2, the last visible only with strong solutions. Alkaline hsmatin, obtained by the action of concentrated potash in the cold, gives two indistinct bands a t X 582 and 546.5 ; after heating nearly to boiling and adding water, only a single feeble band a t 580.7 can be observed, but if alcohol is added instead of water a more intense ab- sorption, varying in position between 597.4 and 600.2 results. If the diluted blood, mixed with potassium hydroxide, is heated to 70' whilst observing with the spectroscope, an intense bnnd a t 559.1 and a feeble one a t 529.2 come into view as those a t 582 and 546.5 disappear: this is the spectrum of reduced haematin resulting from the action of a trace of potassium sulphide, produced by the decomposition of the albumin by the alkali. The same spectrum of reduced haematin is obtained if the alkaline blood is left for a n hour or two in the cold, or when ammonium sulphide is added to either acid or alkaIine haematin. On adding concentrated sulphuric acid to blood and warming, hemato- porphyrin is produced, which in acid solution gives two bands whose position varies between 553-558 and 599-604-5 respectively : the addition of a small excess of alkali produces a spectrum of four intense bands, also somewhat variable in position. If hydrogen sulphide and air are simultaneously passed through diluted blood, sulphohaemoglobin results; this gives a sharp band a t 619.8. All the above colouring matters absorb the blue and violet of the spectrum to a greater or less extent. Of the above spectra, those of reduced haematin and of acid hamato- porphyrin, especially the former, are the most sensitive for the recognition of old or minute blood stains. Very old stains, in which the hsemoglobin has become insoluble, can be dissolved by potassium cyanide solution, and on adding excess of ammonium sulphide to this solution reduced haematin is obtained. Observations of the spectrum of blood containing carbon monoxide show that the spectra are all compromises, the bands of carbonyl hsmoglobin, which lie nearer to the blue end than those of oxyhaemo- globin, blending with those of the latter substance to give intermediate712 ABSTRACTS OF CHEMICAL PAPERS. bands, the position of which depends on the amount of carbon mon- oxide absorbed. Charts of the above spectra and a large amount of detailed informa- tion on the whole subject are given in the paper. New Instrument for the Estimation of the amount of Haemo- globin in Blood. By GUSTAV GAERTNER (Monutsh., 1901, 22, 745-'747).-The method depends on the fact that haemoglobin absorbs the chemically active rays of the spectrum. The effect of light transmitted through a given thickness of blood, on a photographic plate, is inversely proportional to the amount of haemoglobin present. The paper must be consulted for details of the apparatus. M. J. S. K. J. P. 0. Hemoglobin Crystals for the Distinction between Human and Animal Blood. By MOSER (Cl~em. Centr., 1901, ii, 858-859 ; from Vierteljahes-schr. ger. Med. ofentl. Sanitatswes.).-The author has experimented with human blood and the blood of various animals, such as horses, sheep, calves, oxen, pigs, and rabbits. From fresh blood or stale blood, if still liquid or moist, and even from blood spots, if these have not been dry too long, hamoglobin crystals may be obtained. The blood is, if necessary, allowed to dry on a slide, then rubbed with a little water and a few drops pressed through calico on to an object glass. After putting on the cover glass, the dried edges are ex- amined first and bhould they contain crystals, the blood is sure to be of animal origin. I n any case, hzmoglobin crystals will be deposited sooner or later, gerierally within 24 to 48 hours ; those of human blood are characterised by belonging to the rhombic system and by large sharp edges and the presence of broad rectangular plates. Another conclusive fact is that the crystals of animal blood are invariably accompanied by crystals of oxyhzmoglo bin. L. DE E(.
