SCHLESINGER (Virchow.’s Archiv, 125, 146-181, and 340-:363).-The diastatic activity of saliva was estimated in a number of cases of healthy and diseased persons. The smallest ferment activity was found in a case of diabetes mellitus (0.42 per cent.), and in a case of phthisis (0-45). The other cases of diabetes show a slight diminution, as do also the other cases of phthisis, tjphoid, chronic nephritic, mercurial saliva- tion, iodism, articular rheumatism, dyspepsia, cancer, and jaundice. In spinal paralysis, no difference was observed. The eight normal cases showed only slight differences ; the greatest difference being 0.097 (0.878 and 0.781). In young children, the ferment activity is rather less than in adults.The addition of an alcoholic solution of thymol for autiseptic pur- poses lessened the diastatic activity in one-half of the normal, and one-PHYSIOLOGICAL CHENISTRY. 1523 third of the pathological cases ; in the remaining two-thirds, i t did not ; the hindering influeuce is believed to be due both to the thymol and the alcohol, chiefly on the bacteria in the saliva, which appear to be more 8bundant in pathological than in healthy saliva, A very complete history of the subject and bibliography are given. Gelatin as a Reagent for the Detection of Tryptic Enzymes. By C. FERMI (Chew. Centr., 1891, ii, 87; from Arch. Hygiene, 12, 240--260).-1n place of fibrin, the author has successfully employed gelatin as a means of detecting the presence of proteolytic enzymes.The gelatiu is prepared from 5-10 grams of pure gelatin, and 93 grams of aqueous thymol or phenol solntion; 5-10 C.C. of this gelatin is r u n into a test-tube, allowed to solidify, and the solution under examination, to which a little tbymol or phenol has been added, is run on to the surface. If at the end of five or six days the gelatin shows no signs of liquefying, the absence of enzymes is established. By means of this reagent placed in graduated cylinders, the author has been enabled to study the properties of the unorganised ferments, and their behaviour with animal and vegetable tissues, Neutral Sulphur and Metabolism. By RUDENKO (V~TC~OW’S Archiv, 125, lOt-l14).--In addition to the sulphur present in the urine as sulphates (preformed and ethereal), there is an organic sub- stance or substances, which contain the so-called non-oxidised or neutral sulphur. The amount of this present varies considerably, and a quantity of it was prepared from dogs’ urine.The following general conclusions from experiments and observations in cases of disease are given :- (1.) Many processes which increase the decomposition of the body proteids do not raise also the power of oxidation, but lessen it. This is indicated by the lactic acid which appears in tbe urine in phos- phorus poisoning, the sugar in cai-bonk oxide poisoning, and the sarcolactic acid that occurs in the urine during artificial dyspnma (Hoppe-Seyler) comes under the same category. (2.) In certain circumstmces, not well explicable, the neutral sulphur administered to dogs undergoes complete oxidation in.the body; but the separation from the or6anim-n takes much longer than if the same element were given combined as sulphuric acid, W, D. H. J. W. L, W. D. H Influence of Sulphonal on Proteid Metabolism. By M. HAHN ( Virchow’s Archiv, 125, 182--188).-Several observers having shown that certain narcotics increase nitrogenous metabolism, it was considered advisable to investigate the question so far as it, relates to sulphonal, A series of observations were made on a dog, for periods without, and for periods with, the administration of the drug, in addition to the food. The body weight, the nitrogen ingested and excreted, the sp. gr. and amount of the urine, and the sodium chloride in it, are given in tabular form.The periods during which sulphonal was given were two in number. The first pro- duced an increased output of nitrogen, which lasted for a week or1524 ABSTRACT& OF OHEMIOAL PAPERS. mire after the drug was stopped. In the second experiment, the excretion of nitrogen was somewhat diminished, but there was a good deal of diarrhcea, which increa'sed the difficulties of the experi- ment,, which therefore demands repetition. In both cases the output of sodium chloride was increased. W. D. H. By A, E. WRJGHT (Brit. Med. Joum., ii, 1891, 641-644).-Wooldridge's " tissue fibrinogens " were prepared from testis and thjmus by precipitating them from an ayiieous extract of the organ8 by means of acetic acid. They were found to give the biuret reaction, arid the nitric acid test for proteoses, but the opinion is expressed that they are not proteoses, but substances from which proteoses are readily formed. Further investigation showed thRt they were nucleo-albumins.The question whether injection of solu- tions of tissue fibrinogens acts protectively against the Bacillus authracis was tested on rabbits. The results are inconstant, but tend t o show that there is a certain amount of immunity produced. Decomposition of Albumin in Fasting. By I. MUNK (Bied. Centr., 20, 521-522; from Cent. Med. Tviss., 27, 833--836).-1n opposition to Klempercr's view that the value for the loss of nitrogen (average 11.3 grams a day) obtained in the fasting experiment made on Cetti by Senator, Zuntz, and others was high owing to tuberculosis the author obtained exactly the same mean result in an experiment with a perfectly healthy man who fasted for six days.Voit obtained the same result in a series of experiments with young men. Finally Succi, during a f a s t of 10 days, lost an average daily amount of 10.7 grams of nitrogen. The chief factors which determine the loss of nitrogen are the small amount of fat in the body and the large amount of water consumed. It was observed that on the two days following the fast, when albumin (101 grams), fat (139 grams), and carbohydrates (309 grams) were given, cnly 54 grams of albumin was decomposed and quite 40 grams deposited; owing to the con- Rumpticn of nm-nitrogenous matter, the loss of nitrogen was reduced t o 8.3 grams.*issue Fibrinogens. W. D. H. N. H. M. Influence of Increased Muscle Activity on the Decomposi- tion of Albumin. By F. HIRSCHFELD (Bied. C'entr., 20, 319-5203 from Centr. Med. Wiss., 29, 66-67).-The author, in experiments made on himself, estimated the daily nitrogen secretions, first, with a mixed diet containing albumin (162 grams), fat (16'7 grams), and carbohydrates (327 grams) ; and then with a diet containing albumin (37-43) grams, fat, (164-183 grams), and carbohydrates (379-408 p m s ) . The increased muscle activity consisted in doing hard work for six hours daily, and i n ascending 400-500 metres. With suffi- cient food, i t was found that the decomposition of albumin was not increased, whether the food contained much or little albumin. If, however, the food is insufficient, a considerable loss of albumin takes place.During three days of rest the author lost 1.5, 2.1, and 4.6 grams of nitrogen, and during three days, on which he worked, 2.1, 5.1, and 6 grams of nitrogen. The results explain those of Argutinslij,PHYS1C)LOQICAL CFlEhZISTRT. 1585 who found the amount of albumin decomposed after muscular exertion to be increased when the feeding was insufficient. Importance of Asparagine for Feeding. By J. KONIG ( B i d Centr., 20, 515-516 ; from Centr. Med. Wiss., 28,849-852).-After Pfeiffer and Schnlze showed that in germinating plants, asparagine is formed from decomposing reserve a1 bumin, that the asparagine remains as such in air free from carbonic anhydride, whilst iu presence of carbonic anhydride it disappears, probably again yielding albumin, it seemed likely that asparagine might in the animal organism be re- generated into albumin when a food is used wliich is poor in nitrogen but rich in carbohydrates; or a t least, that i t might economise albumin.The experiments of Weiske, Kennepohl, Schulze, and others with rabbits, fowls, geese, sheep, and cows supported this view, showing that asparagine gives rise to deposition of albumin and to illcreased milk production. On the other hand, Munk found that i n tlie case of a dog fed exclusively with meat, or with a mixture of meat and carbohydrates, there was no diminution, but rather a slight increase, in the amount of albumin lost. Knieriem, who also experi- mented with a dog, found no increase in the amount of urine when asparagine was given.17. Voit and Politis, in experiments with rats, found that asparaginc did not give rise to any saving of albumin. The results of Zuntz and Hagemann pointed to the same conclusion. The author considers the question to be still an open one. Influence of Acid Mineral Salts on the Composition of Bones. Br H. WEISKS (Landw. Versuchs-Stat., 39,241-268; com- pare this vol., p. 848).-The experiments were ngitiri made with rabbits ; they were all of the same litter, and were 10; days old. The object was to ascertain the effect of a food with an alkaline ash (hay) with or without oats, a3 compared with a food which gives an acid ash (oats), and partly with addition of dihydrogen sodiiirn phosphate. The exclusive use of oats might have some action, and the addition of theacid salt would intensify the action.The urine of the rabbits fed with hay (0) and with hay aud oats (1 and 2) was alkaline, but where oats was given alone (3 and 4) and with the salt ( 5 and 6), the urine wus respcctivelg distinctly and strongly acid. The followirig table shows the initial and final weights in grams of each rabbit (the experimeut lasted three months), and the weight of the dry, fat free skeletons :- Initial weight.. 1750 20d0 1830 1900 1915 2040 1925 Final weight .. 2430 3480 3360 2320 1740 2160 l4SG Skeleton . . . . . . 87.66 115.92 113.59 74.13 64.44 67.15 60.37 There was thus a considerable difference in the weight of the bones with the different feeding, Nos. 1 and 2 (fed with hay and oats) being much the heaviest, and 3-6 the lightest.The latter in the fresh condition are, however, relatively the heavier. The bones of 0, 1, and 2 were thicker and harder than the other&; those of No. tj were very thin and breakable. The percentage of ash in the short bones ( a ) , the long bones ( b ) , and the teeth (c) was as follows:- N. H. M. N. H. M.

But it is rather the amount of ash which varies than the composition. The extraction of mineral matter from the bones is caused by the acid nature of the food. Although of the three normally fed rabbits No. 0 had the lightest skeleton, the percentage amount of total ash and ash constituents was approximately equal in all three ; whilst the bones of the other rabbits contained not only absolutely but relatively less ash, and were in part very thin-walled and little capaple of re- sistance. N. H. M. Action of Sugars in the Body. By P. ALBERTONI (Chent. Centr., 1891, ii, 44; from Ann. Chim. Farm, 13, 145--159).-Sugar was administered to dogs, which had fasted for 24 hours, and at the end of a given time they were killed by admitting air into the veins.The contents of the stomach were then collected and examined. Experi- ments were made with maltose, cane sugar, and lactose. Maltose, and especially cane sugar, are absorbed more quickly than glucose. In an hour 70 to 80 per cent. was absorbed. Lactose, however, is different, the amount absorbed being only from 20 to 40 per cent. The absarp- tion is especially small if the solutions are denser than the blood. There is always a certain quantity of sugar found in the tissues outside the stomach. Dilute solutions of lactose are more easily absorbed, the proportion in which i t is contained in milk being the most advan- tageous. Lactose and levulose act on the circulatory system partly like, and partly unlike, glucose, maltose, and cane sugar.The former do not increase the blood pre~sure, but lessen the pulse frequency ; the latter cause a rise of 10-20 mm. in pressure. This is due to their direct actmion on the blood. Sugar absorbed by the natural channels does not increase the body temperature. W. D. H. Formation of Glycogen in the Liver. By E. NEBELTHAU (Zeit. Biol., 28, 138--1i6).-1n the present research, hens and rabbits were the animals chiefly employed, and the principal investigations relate to the influence of certain drugs on the liver glycogen ; t'he animals used had been deprived of food for some days previous to the experiments, and were killed as nearly as possible the same length of time after the administration of the drug. The work of Rohmann is criticised, as he did not pay attention to this latter point ; from 20-24 hours after the administration of food or drug being the time when the maximum of glycogen is found.In some cases, the glycogen in the muscles was estimated also, in all cases by Kiilz's method. The danger of trusting implicitly to single control animals is pointed out, as the glycogen varies greatly in animalsPHYSIOLOGICAL CHEMISTRY. 1527 treated in precisely the same way. Full tables of analjses are giveu throughout. Chloral hydrate was found to increase the hepatic glycogen, t h e lethargic condition induced by this drug, and the consequent corn- parative immobility of the animals, tending to its accumulation ; this suggested similar investigations regarding other narcotics ; the increase was always found after the administration of chloralamide, paraldehyde, and sulphoual ; occasionally the same was observed after the injection of ether, chloroform, and alcohol.Urethane did not produce a marked effect ; in only two out of seven experiments. was there a slight increase of glycogen in the liver. Ammoniacal compounds are stated by Rohmann (Pjiiger’s Arclziti, 39, 21) to cause increase of the glycogen in the liver ; this led him to certain general conclusions regarding the part played by nitro- genous compounds in the formation of carbohydrate material in the body ; in the presenf research, ammonium citrate, ammonium formate, benzamide, formrtmide, ammonium lactate, and asparagine were used. On the whole, the results obtained confirm those of Rijhmann ; all increase the liver glycogen; this is true also for lactic acid com- pounds, which, according to Rohmann, have not this effect.The febrifuges, antipyrin, kairin, and quinine, all increase the hepatic glycogen. So does sectionof the cervical spinal cord; this is a, confirmation of an old observation of Claude Bernard’s. By E. L. JONES (J. PhpioZ., 12, 299--346).-Purther observations on the sp. gr. of the blood under various conditions (compare Abstr., 1887, 608) led to the fol- lowing results. 1. The sp. gr. of the blood varies in different parts of the body, but that from any part bears, m t . par., a definite relation to that taken from any other part. It is usually the same in corresponding parts of the symmetrical halves of the body.Variations in blood supply to any part are the most frequent causes of alteration of t h e sp. gr. there, while it remains unchanged elsewhere. 2. The sp. gr. is very high in birds, and low in such animals as 3. The sp. gr. varies considerably in different persons; it ia generally lower in women than in men ; before the fifteenth year it is about the. same in both sexes; it is higher in old women than old men. In males, the sp. gr. is about 1.066 at birth, and falls gradually for three years to 1.050 ; then it rises till about the seventeenth year, when it is about 1.058 ; it remains at about this height till old age comes on, when it falls slightly. In females the chief difference from the foregoing is that during tvhe greater part of life it is 1.0555 instead of 1.058.I n girls from 15 to 22 the limit consistent with health is very low, and chlorosis appears to be an exaggeration of this physiological condition. Further extensive data are given respecting the variations in sp. gr. with complexion, race, physique, food , exercise, sleep, menstruation, anaemia of various kinds, heart diseases, kidney diseases, various fevers, phthisis, syphilis, and many other diseases. W. D. H. Specific Gravity of Blood. frogs. W. D. H.152s ABSTRACTS OF CXEMUIOAL PAF’ERS. Glycolysis in the Blood. By M. ARTEUS (ArcL. de PhysioZ., 1691, 425--439).-L&pine and Barral have described in the Mood, prob- ably derived from the white corpuscles, ferment which has the power of destroying sugar, and the absence of which they consider to be a cause of diabetes.l n the present experiments, i t was foand that glycolysiv in the blood is a phenomenon of fermentation, but the ferment is absent in the circulating blood. I t is formed when the blood is shed, as a result of the disintegration of formed elements other than the red corpuecles. Glycolysis in the blood is thus a cadaveric phenomenon like coagulation. Influence of Acids and Alkalis on the Alkalinity of Human Blood, and on the Reaction of the Urine. By A. FREUDBERG ( Virchow’s Archiv, 125, 566-600). -The a1 kalinit y of the blood was estimated by a slight modification of v. Jaksch’s method of titrating small quantities with very dilute tartaric acid. Recent researches by Bohr have shown that estimation of tbe carbonic anhydride leads to an incorrect estimate of the alkalinity.The reaction of the urine was estimated by titration with normal soda solution or normal oxalic acid according as the original urine was acid or alkaline respectively. The result of a great uumber of observations on the blood and urine of patients suffering from a variety of diseases, and also after the administration internally of various acids and alkalis, are given in tabular form, from +hich the following general concln- sions are drawn :- Hydrochloric acid (4-8 grs. of the officinal acid per diem) does not alter the alkalinity of the blood. Only one exception was noted. The acidity of the urine is, however, always increased. Lactic acid (10-30 grs.) lessens the alkalinity of the blood by one-fifth to one-fourth. The acidity of the urine is increased, but not markedly so, and not in a degree corresponding with the amount of acid given.Tartaric acid (5-10 grs.) lessens tho alkalinity of the blood by one-sixth ; it also increases the acidity of the urine, but not markedly. I t also is burnt to a great extent i n the body. Sodium hydrogen carbonate (5-15 grs.) in three cases increased the alkalinity of the blood by one-fourth; in two other cases there was no change. W. D. H. It is no doubt to a large extent oxidised in the body. I n all cases the urine was strongly alkaline. W. D. H. Xanthine Substances in Urine. By G. SALOMON (Virchow’8 Archiv, 125, 554--556).--Previous investigations having shown that xanthine, paraxanthine, and heteroxauthine are constituents of normal urine, and can be obtained in small quantities from large volume8 of urine, the present reseal-ch is directed to ascertaining whether they can be deinonstrated to exist in smaller quantities of urine.The property of the para- and hetero-compounds to form sparingly soluble crystalline compounds with sodium or potassium hydroxide is the must important reaction for separating the members of the group ; after the precipitation of these compounds, xanthine remains in solu- tion. The distinction between paraxanthine and heteroxanthinePHYSIOLOGICAL CHEMISTRY. 1529 requires the use of more material, and can be accomplished by the corrosive sublimate and picric acid reactions. The crystalline compounds of paraxanthine and heteroxanthine with sodium hydroxide are figured, and there is a description of their crptallogrephy.They melt about 300'. The compounds with potassium hydroxide have similar reactions, and a higher melting point. The paper concludes with a brief account of 22 observations of human urine. In normal urine, paraxanthine appears to be tlie member of the group most frequently present; i n seven cases of various diseases, although the soda reaction was always successful, paraxant hine was some times absent. Oxidation of Aromatic Substances in the Animal Organism. By K. KLINGENBERG (Chem. Cenfr., 1891, ii, 39-40 ; from Diss. Rost0c.k fnst. Pharm. physiol. Chem.).-Aromatic substances belonging to various groups were given to dogs, and their urine for the 24 hours following was examined, with the following results :- 1.Diphenyl is chauged in the organism to, and excreted as, para- hydrox ydipheny 1. 2. Beneidine behaves bimilarly to quinone, is non-toxic, and is ex- creted unchanged. 3. Paradibromodiphenyl is also not poisonous, and undergoes no oxidation in the body. 4. Paramidodiphenyl kills in two hours, changing the pigment of the blood corpuscles to methtemoglobin. 5. Carbnzole is not poisonous, and is oxidised in the body to hydr- oxjcarbazole, leaving it by the urine a s an ethereal bydrogen sulphate. 6. Fluorene is not poisonous. No increase in the ethereal hydrogen snlphates is found after its administration. 7. Phenanthrene and phenanthraquinone are both very well borne. They probably act as antiseptics, and diminish the output of combined sulphuric acid. Glycuronic acid compounds were not found in the urine.8. Diphenylamine is osidised in the body to parahydroxydipkenyl- amine. 9. Dipheuylmebhane is changed in the body to parahydroxJdi- phenylmethane. It thus appears to be the rule that the hydroxylativn of aromatic substances within the body, as well as outside of it, consists in the formation of substitution products in which hydroxyl occupies t h e para-posi tion. If the para-position is already occupied, no hydroxyl- king action follows. By E. NEBELTHAW (Zeit. BioZ., 28, 130-137).-Thierfelder (Abstr,, 1886, 572) states t h a t during inanition, and after the administration of chloral b ydrate, glycuronic acid in combination as urochloralic acid is found in the urine. The animals with which he experimented had received no food for six days previous tro the experiments.Consider- ing that this length of time is sufficient for the complete disappearance W. D. H. W. D. H. Formation of Glycuronic Acid during Inanition.1530 ABSTKAOTS OF CHEMICAL PAPERS. of‘ all the glycogen of the body, he concludes that in the appearance of glycuronic acid in the urine he has proof of the formation of carbo- hydrate from prote’id. Without at all denying this possibility, the present paper points out that Thierfelder’s experiments do not prove it, as, after six days’ hunger, there is always a considerable amount of glycogen left, both in the liver and in the muscles. The glycogen was estimated by Kulz’s method. Elimination of Urea in Fever. 3.y H. C. WOOD and J. MARSHALL (Journ. of Nervous and Mental Disease, 1891,l-9) .--It is well known that the amount of urea eliminated during fever is greater than the normal.It seems, however, not to be settled whether this is an inte- grant part of the febrile process, or caused by the action of the excessive heat on certain organs, or by soma of the derangements of the bodily functions produced by fever. The latter theory seems probable, as Schleich (Arch. Exper. Patlc. u. Pharm., 4) and Naunyn (Berlin klin. Woch., 1869), in dogs, and Bartels (Greifswalder med. Beit., 3, 1864), in man, found that arti6cial elevation of the body temperature pro- duced an increawd output of urea. Many clinical observers have noted that the increased elimination of urea, is not necessarily proportionate to the body temperature, and that in the crisis of the fever there is apt to be an extraordinary amount excreted, although the body temperature may be normal or even subnormal; and that in many diseases with low temperature, like cancer, scurvy, diabetes, gout, and especially various affections of the liver, there is again a great increase in urea elimination.In this relation, cases of hepatic fever (that is, the fever produced by stones in the gall-bladder or ducts) become important. The generd results of pi*evious and the present experiments show that, even in hepatic fever, a distinct rise of temperature is usually accompanied with an increase in the elimination of urea. It is, however, most important to remember that temperature is not necessarily a measure of fever; there may be increased heat produc- tion, even when the body temperature is below the normal.It is evident that careful calorimetrical studies are urgently needed, by which a comparison may be made between heat production (instead of body temperature) and urea elimination. It may be, for instance, that heat production is much increased during the crisis of a fever. This would explain the critical increase of urea. The opposite question then arises, whether intense fever with great increase of heat production can exist without corresponding increase in the excretion of urea. Two experiments were made on dogs, which answer this question in the affirmative; after fasting for 24 hours, the urea eliminated was measured for 12 hours, and then the medulla divided at its junction with the pons.This leads to an excessive production of animal heat. The animals lived a few hours after the operation, and the urea excreted during that time was estimated ; the results were as follows :- W. D.

Therapeutic and Physiological Effects of Ozone. By D. LABBP and OIJDIN (Compt. rend., 113, 141--144).-Ozone, prepared by the chemical method, is always impure and poisonous, owing to the pre- sence of phosphorous acid. The authors employ an ozone generator, consisting of a closed glass tube containing rarefied air (which acts as one of the poles), surrounded bya tube on the inner surface of which is a metallic thread.The space between the tubes is 3-4 mm., and across this space pass the sparks that produce the ozone. The tubes being fixed vertically, the slight rise of temperature resulting from the discharge causes a continuous upward current of ozonised air, which mixes with the unaltered air in the apartment. Under these conditions, if care be taken that the quantity of ozone does not exceed 0*011-0.012 milligram per litre, the ozonisod air can be breathed even by young children without injurious effect. When the atmo- sphere is breathed by anaemic subjects, there is a rapid increase in the quantity of hsemoglobin in the blood.Cultivations of the bacillus of tubercle on peptonised gelatin seem to be completely sterilised by the action of the ozonised air. Ten tubes of the kind described, each being about 800 mm. long, were placed in a laboratory of 300 cubic metres air space, and were actuated by an alternating current from a Gramme machine with a potential of 7000 volts. After about a quarter of an hour, the laboratory was filled with a bluish cloud of aluminium or aluminium oxide, and direct experiment showed that the electric discharge caused the volatilisation of weighable quantities of aluminium from the electrodes. C. H. B. By C . BINZ (Vi~how’s Archiv, 125, 196--197).-1n Hermann’s Handbuch, Engelmann speaks sceptically concerning Binz’s observation on the deadly influ- ence of quinine on amoeboid movement. The latter observer now publishes a letter from Engelmann, with an enclosure of a dissertation by ten Bosch, one of his pupils, in which it is shown that Binz is .correct, and, moreover, that quinamiue has only one-sixth of the toxic power of quinine on protoplasm. Saponins. Ry R. KOBERT (Chern. Centr., 1891, ii, 176; from Pharqn. Centralhalle, 30, 335).-The author considers that there are a series of saponins of the general formula C,H, - *Ole, several of which Quinine a8 a Protoplasmic Poison. W. D. H.1532 ABSTRACTS OF GHEMIOAL PAPERS. are known. Saponins of the same formula and of the same chemical properties appear to have different physiological characteristics, and show great differences in t.heir poisonous action. The sapotoxin of A grostemnza githago (corn cockle), one of these substances, is absorbed both by the subcutaneous tissues and by the intestinal canal, and thus acts as a dangerous poison. It is recommeuded that, before using this seed as a food, the shell arid embryo shall be separated. J. W. L,

1532 ABSTRACTS OF GHEMIOAL PAPERS. Chemistry of Vegetable Physiology and Agriculture. Manufacture of Pure Yeast. By H. ]ELION (BUZZ. SOC. Chi~z. r3], 5, 451).-The author describes and figures a steriliser and a fermenting apparatus which is capable of yielding 10 kilos. of absc- lntely pure yeast at each charge. (Compare Fernbach, this vol., p. 352.) T. G. N. Action of Hydrogen Fluoride and of Fluorides on Yeast, By J. EFFRONT (Bull. SOC. Chin). [3], 5, 476-480; compare this vol., pp. Pi7 and 488). Hydrogen fluoride, when present in ferment- ing saccharine solutions, retards the activity of yeast, and 5.3 milii- grams of hydrogen fluoride per 100 C.C. will arrest the fermentation. Small amounts of potassium fluoride (up to 5.5 milligrams per 100 C.C. of solution) augment the mtivit,y of the yeast, and although an excess of this salt h a s a deterrent effect on the fermentation of cane sugar dissolved in distilled water, the quantity may be increased, with beneficial results, to 50 milligrams per 100 C.C.o€ a wort con- taining nutrient materials. Bread Fermentation. By 1;. BOVTROUX (Cmpt. rend., 113, 203--206).-1n lea-rens to which no yeast had ever been added since time immemorial, the author always found yeasts, and he isolated five distinct species, two of which are very active in producing alco- holic fermentation. From the flour, he isolated three distinct species of bacteria : a, which secretes a diastase that dissolves cooked gluten and saccharifies starch paste, but does not attack sugar: p, whir.11 produces fermentation, with evolution of gas, in a mixture of flour and water sterilised by heat; and y, obtained from the bran, which produces a ferment-ation, with evolution of gas, in a mixture of bran and water.Bacillus a followed by yeast produces alcoholic fcr- ment ati on. Direct experiment showed that the yeasts active in producing alcoholic fermentation can readily be cultivated in paste, but this is not the case with the yeasts little active in alcoholic feimentation, nor with the bacteria a, p, y. The pasts can be Cultivated in paste containing 0.3 per cent. of tartaric acid, but this quantity of acid completely prevents the " rising " of paste to which no leaven has been added, LL result which shows that the yeast is the essential agent T.

N.VEGETABLE PHY SIOLOQT AND XQRIOULTURE. 1533 in bread fermentation, and if the bacteria play any useful part, it is only in the production of the sugar.Flour charged with its natural microbes, mixed with salt water and pure yeast,, and allowed to '' rise," contains practically the same proportion of gluten as the original flour, and hence the fermentation of the glucose is not essential, but is a perturbation. Starch also is not affected to any great extent during the process. An aqueous extract of bran, freed from bacteria, saccharifies starch paste, but not, crude starch, and this is true also of the amylose secreted by bacillus x . The only fermentable material that remains is the soluble part of the flour containing the preformed sugar, dextrin, and salts. The author concludes that bread fermentation consists essentially of the alcoholic fermentation of the sugar pre-existing in the flour.The yeast not only produces the gas that ai5rates the bread, but it also prevents the development of the bacteria. The difficulty of detecting the yeast in the paste arises from the intimate manner in which i t is mixed up with the dough, but the presence of the yeast cells is more readily recognised than the presence of bacteria. Nitrogen Assimilation of the Leguminosae. By F. NOBBE, E. SCHMID, L. HILTNER, and E. HOTTER (Landw. Versuchs-Stat., 39, 327-3359).-The objects of the experiments were (1) to include some kinds of papilionaceous woody plants, (2) to infect with pure cultivations of bacteria from (a) soil and ( 6 ) root nodules, as well as with soil extracts, (3) to ascertain whether one and the same bacterium produces nodules in all leguminous plants, or whether tbe various orders have their special organisms.The first series of experiments included Pisuin sativum, Robinia pseudacacia, Cytisus laburnum, and Gleditschia triaknnthos. The plants were grown iri pure, sterilised sand containing 5 per cent. of powdered peat and 0.5 per cent. of pure chalk, and watered with a nutritive solution containing potassium chloride (0*0161), magnesium sulphate (0*0121), dihydrogen potassium phosphate (0.0133), and ferric phosphate (0.0033 per cent.). The peat was found to be injurious, owing to the formation of acids, and especially so in the first pot of each set, in wbich no chalk was used. The vessels were of glass and held 6.5 litres.The seeds were sterilised, and were allowed to germinate in sterilised water. The sand in the pots w m covered with cotton wool, and the whole heated at 95". There were 12 pots (5 plants i n each pot) which were seeded as follows:-(2) Lupin soil extract, (3) pea soil extract, (4) Gleditschin soil extract, ( 5 ) Robinia soil extract, (6) Cytisus soil extract; all these were seeded 7th June; (7) pure cultivation of pea nodule bacteria, (8) pure cultivation of Robinia nodule bacteria (both seeded 27th June). Nos. 9-12 were not seeded, but (10) had calcium nitrate (0.973 gram on 8th July), and (12) had ammonium sulphate (0.803 gram on 30th June). Pisurn sntivum.-The plants were set on the 21st May, and by the middle of June began to show nitrogen hunger.On the 27th of June, the pea soil extract (3) began to have an effect ; and on the 30th, the plants seeded with Gleditschia (4) and C'ytisus ( 6 ) soil extracts began t o improve, whilst the Robiizia soil extract ( 5 ) did not C. H. B. VOL. LX, 5 k1534 ABSTRACTS OF CHEMICAL PAPERS. show effect until the 10th of July. The lupin soil extract had no effect a t all (owing,.perhaps, to its not being fresh enough), and the subsequent application of fresh soil extract also had no effect, beinp probably too late ; the negative resultR obtained with Nos. 7 and I are also supposed to be due to the lateness of the application. Calcium nitrate. and ammonium sulphate, produced a beneficial effect, two and three days after their application. The plants of both these pots produced flowers, whilst not one of the successfully infected plant8 did.On the other hand, almost all of the plants which did not recover from their state of nitrogen lbunger (Nos. 2, 7, 8, 9, and 11), in spite of their scanty growth, produced flowers, and some even small fruit. The results contirm those obtained by Hellriegel, that the nodule bacteria give an impetus to vegetation, and hinder flower and fruit formation. All the successfully infected plants had nodules ; one plant (in pot 4) had 4572 normal nodules. The nodules were almost all in the upper parts of the roots ; this was also found to be the case in the experiments with other plants. The quantitative results a h regards total produce and nitrogen are given in the table on next page.Rohzniapseudacacia.-The period of hunger began at the end of June and ceased first in the case of the plants seeded with the Robinia nodule bacteria (No. 8), and next where Robinia soil extract, was given ( 5 ) . The extracts of Cytisus and Qlsditschia soil were dower in producing an effect ; whilst the lupin and pea soil extracts, and the pea nodule bacteria, had no effect at all. Calcium nitrate, and ammonium sulphate, caused a distinct improvement two days after their application, and the plants so treated ripened soonest, and began to lose leaves when the infected plants were still quite fresh. The roots of the plants supplied with ammonia had no nodules, bul those which had nitrate, and Borne of the unsuccessfully seeded pots had. It is at least possible for Robinia to exist without nodules (compare Frank, Ber.deut. hot. Ges., 1890, 292). The nodules are generally larger, but less numerous, than on pea roots. All the success- fully seeded plants had nodules. I n the case of the plants infected with pea nodule bacteria, and of the other plants which were not intentionally infected, but which produced nodales, there was no increased growth. Frank’s view that the bacteria hace no object when the soil contains nitrogen seems to be correct. If it is assumed that the nitrogen assimilation takes place through the leaves, i t is probable that the nodules in pota 2, 3, 7, and 9 were formed at a time when the roots still contained enough nourishment for them, but that the leaves were too much exhausted for the bacteria to enable them to recover.The results of the experiments indicate an essential dieerence in the behaviour of various soil extracts ; Robinia soil extracts acted (with Robinia) the most quickly, and pea soil not at all, whilst other extracts were intermediate in their action. ‘Ihis point is further illustrated by special experiments described f u r - ther on. Suitable infection had a greater vegetative action than an excess of ammonia or nitrate. The quantitative results-amount of dry produce, and the amount of uitrogeu in produce, and in seed sown-are given, together with those obtained with peas, in the €01- lowing table :-Nitrogen.

On examining the roots, however, it was found that many of them had nodules, and it was noticed that the corresponding plants had new leaves still quite fresh. I t seems probable that it' the plants had been left longer, these plants would have continued to grow. Gleditschia tria7cantho.s.-No difference in the various plants was to be seen by the middle of July, and there were no symptoms f nitrogen hunger, but the plants grew very slowly. The plants supplied with nitrogen began to darken about eight days after the application.At the time of taking up (6th October), five plants in pot 10 and two in pot 12 were still healthy; all the others had lost all their leaves. The roots of all the plants were free from nodules. The dry matter of the produce (one plant) varied from 0.603 to 1.036 gram, and the nitrogen from 0.0085 to 0.0111 gram (one seed sown contained 0.0107 gram) in the pots where no nitrogen was. given, so t h a t there was, practically, no gain in any case. The ammonia and nitrate pots gave respectively (in one plant) 1.01G and 1.145 grams of dry matter and 0.0314 and 0.0306 gram of nitrogen.As already shown by Hellriegel, extracts of various soils have quite different action on various plants; this depends not on the number (as Frank assumes), but on the kind, of organisms present. The second series of experiments was similar to the first, except that only half the amount of pent was mixed with the sand. T h e plants were Pisum sativum, Lupinus lutem, and Phaseolus vz/,lgaris, but the lupins did not grow well, owing, it is supposed, to unfavourable conditions of the sand. Yisum sativum.-Tho plants were set on the 7th August, and were infected on the 14th with pure cultivations of bacteria from various sources as follows :-(1) Pea nodules, (2) pea soil, (3) lupin nodules, (4) lupin soil, ( 5 ) Robinia nodules, ( 6 ) Robiitiu soil.All the plauts reached the period of hunger 14 days after the infection, Seven days Jater the plants of pots 1 and 2 began to acquira a darker colonr, and five days later still the plants of pot 3 showed an increase of chlorophyll. The Robinia bacteria remained without action. When taken up (21st October), most of the plants had flowered ; in the case of pots 1-3, the flowers fell off without forming fruit; whilst the small plants of pots 4-6 formed each one fruit with one seed. This result corresponds with that obtained i n the first series with peas. The roots of the plants of pots 1-3 bad all nodules; those of pots A 6 had none. The nodules of pots 1 and 2 were very numerous, sometimes small and round, sometimes 2 mm.long and 0.8 mm. wide, and the bactero'id tissues rose-coloured ; the nodules of pot 3 grew into each other, sometimes extending 0.5 to 1 cm., and giving the root the appearance of being thickened. The nodules pro- duced by pea nodule bacteria were formed on roots of' the 2nd order ; those produced by lupin nodule bacteria on roots of the 3rd order. The result of greatest interest, is that the same (pea nodule) bacteria which, in another experiment, had no effect onBobinia produced nodules No analytical results are given.2nd Series. ~~ I I Dry produce (1 plant).

The numerical results are giveu with those obtained with beans in the table on the preceding page. Phuseohs vdgaris.--The plants were set the 21st August, and infected on the 26th and 27th August, rn follows:-No. 1, not in- fected, calcium nitrate, (2) bean soil extract, (:<) pea soil bacteria, (4) lupin soil bacteria, (5) Robinia soil bacteria, (6) pea nodule bacteria, (7) lupin uodule bacteria, (8) Robirtia nodule bacteria, (9 and 10) nothing.When taken up (27th November), the plants of pot's 1, 4, 5,7-10 were free from nodules ; those infected with bean soil extract (2) and with pea soil and pea nodule bacteria (3 and 6) had numerous nodules ; those of pot 3 being the largest. The view that beans produce nodules, even under sterilked conditions, is therefore erroneous. The nodules of the plants in pots 2 and 4 were in roots of the 3rd order, and from most of them there proceeds a root of the 4th order which often bears nodules, and is thicker than the root on which the nodule is situated. The roots have grown out of the nodule, and are remarkable on account of the large amount of crystals of calciuni oxalatc they contain at the point where they arise, proving that, in the roots as well as in the nodules, lively chemical changes take place, the products of which are not carrietl up into the above-pound portions, but to the roots.Moreover, these observations indicate that the changes connected with the enriching of the plant with nitrogen take place in the nodules. This does not touch the question whether the bacteria assimilate directly the free nitrogen of the air or water, or whether, as seems more probable, the crude nitrogenous material is brought to them from the leaves. The table on the preceding page shows the results of the second series of experiments with peas and beans. Photographs are given of some of the plants at different periods of growth, and, also, of some of the roots. 1u order to show the effect of various nodule organisms in different plants under absolutely identical conditions, five pots were prepared, into each of which 1 lupin, 1 pea, 1 Robinia, 1 C'ytisus, and 1 Gled- itgchia were planted.The pots were seeded with bacteria, from (1) Gleditschitt soil, (2) pea nodules, (3) Robinia nodules, (4) lupin nodules. No. 5 was not seeded. All the plants showed nitrogeii hunger about a month after they were planted; afterwards each plant which had been infected with its own organism (except the Cytisus and Qleditschia) began to grow better tban the others. Only the Robinia of series 1, the pea of series 2, the Robinia of series 3, and the lupins and Robinia of series 4 had nodules. The Robinia nodules of series 1 and 4 were small and few. In the two series of experiments, the evaporation from the plants was ascertained by weighing every day, and so much water given as was necessary to keep the weight a t 60 per cent.of the weight of satura- tion. The results obtained with peas and Robinia are shown in curves, and are of great interest, inasmuch as the evaporation is an approxi- mate measure of assimilation and growth. S . H.

Zeit., 1890, 837).-Beans were grown in speciaJly con- structed pots, and the same precautions taken for keeping out air organisms as Prazmowski used in his experiments. Some of the plants were infected with BaciEZus radicicola (from bean nodules), and others left unseeded.All the infected plants had nodules, whilst none of the uninfected plants'had any : the presence or absence of potassium nitrate or ammonium sulphate had no influence on tho infection. When the bacteria are grown in agar-agar containing only salts and cane-sugar, the growth ceases as soon as the small amount of assimilable nitrogen present is used up. The assimilation of free nitrogen does Dot, therefore, take place under these conditions, and at a temperature between 10' and 20". But the bacillus has the power of utilising the smallest traces of combined nitpogen (nitrate, ammonia, peptone, or amide) in presence of a carbohydrate, especially cane sugar. This power of taking up the minutest traces of nitrogm compounds throws a new light on the symbiosis. In the nodules, the last traces of combined nitrogen are accumulated as reserve albumin in presence of the carbohydrates oE the plant, giving rise to a com- plete nitrogen exhaustion oE the soil round them.The author is acquainted with another organism (Xtreptotrix huinzjica), which also, in presence of carbohSdrates, causes a complete nitrogen exhaustion of the soil, but does not live in symbiosis with Yapilionacese. The various papilionaceous bacteria differ more than the author formerly assumed. Viciu fabn infected with Bacillus ornithopi pro- duced no nodules. The difference in the bacteria of beans and serF- della (Ornithopus sativus) accounts for the fact that sewadella was found free from nodoles growing in a, garden between beans which had numerous nodules. N.H. M. Formation of Starch from Formaldehyde. By T. BOKORNY (Chem. Centr., 1891, ii, 120-121 ; from Ber. deut. bot. Ges., 9, 103- L06).-h continuation of previous researches on the formation of starch from methylene dimethyl ether by algw (Landw. Versuchs-Stat., 36, 229-242), the author has grown algae (Spirogyra mnjuscula) In solutions containing sodium hydroxymethylsulphonate, and has observed the formation of very considerable quantities of starch. The expeyiments lasted five days, the vessels being kept in an atmo- sphere free from carbonic anhydride, and exposed to the light during the daytime. Blank experiments were carried out at the same time, with the result that, in these cases, no formation of starch occurred. In order to ueutralise the sodium hydrogen sulphite which is formed irom the sulphonate, a little dipotassium or disodium phosphate was added to the solutions.The solutions contained 1 part of the sulphonate in 1000.

On the four later dates, the sugar in the leaves was estimated; 0.436, 1,465, 1.321, and 0.813 per cent. respectively being found. This sugar did not reduce Feliling's solution until after inversion. In addition to the vegetable acids above mentioiied, crystals of calcium oxalate were seen under the microscope, and traces of formic and acetic acids were obtained by distilling the juice. The distillate from currant juice gave indications of an aldehyde. The progressive increase iu the percentage of acid during the whole period is not in harmony with the old view, that the sugar was formed at the expense of the acid. The disappearance of succinic acid, as ripening is approached, suggests the theory that the other acids are formed synthetically from oxalic and succinic acids.The presence of sac- charose alone in the leaves (which organs are doubtless the seat of the genesis of the carbohydrates), in proportions which increase as the ripening stage is approached, but subsequently diminish, tends to indicate that the formation of saccharose is the first stage in the pro- duction of the sugars, and that the transformation into glncoses inVEGETABLE PHYSIOLOGY AND XGRIOULTURE. 1541 2lst May. the fruit is effected by the acids there present.

The results are two voluminous for reproduction. The most notable features are the invariable diminution in the amount of acid, which diminution was the more considerable as the fermenta- tion was the more vigorous. In no case did the addition of sugar cause a proportional increase in the glycerol, but merely a compara- tively small augmentation.The sugar which escaped fermentation was entirely converted into levulose. The qualitative results of the action of various reagents on the juice of black and red currants, as well as the characters of their Absorption spectra, indicate that the colouring matters of these fruits are closely allied if not identical.

Influence of Iron and Calcium Sulphates on Nitrification. By P. PICHARD (Compf. rend., 112,1455-1458).--In a pure siliceous sand, kept sufficiently moist and containing unaltered nitrogenaus organic matter (cotton oilcake) to the extent of about 1 gram of nitro- gen per kilo., the addition of 0.1 per cent. of iron sulphate reduced the loss of nitrogen for seven months from 47.65 to 18.36 per cent., ant1 increased the gain of nitric nitrogen from 1.43 to 10.40 per cent., and that of ammoniacal nitrogen from 4.49 to 11.22 per cent. With 10 per cent. of clay mixed with the saud, the loss of nitrogen was not sensibly reduced, the gain in nitric nitrogen was increased from 5.10 to 15.92 per cent., and the gain in ammoniacnl nitrogen reduced from 16.94 to 12-75 per cent.by the use of the iron sulphate. Sand containing 1 per cent. of calcium carbonate with iron sulphate did not show any sensible reduction of the loss of nitrogen ; the gain of nitric nitrogen diminished from 5.10 to 2.55 per cent., and of smmoniacal nitrogen increased from 6.43 to 10.40 per cent. In sand containing clay and calcium carbonate, iron sulpbate reduced the loss of nitrogen from 31.63 to 23.87 per cent., diminished the gain of nitric nitrogen from 7.14 to 6.43 per cent., and aug- mented the gain of ammoniacal nitrogen from 18.57 to 26-751544 ABSTRAC'I'S OF CHEMICAL PAPERS. per cent. In the same medium, double and triple allowances of iron sulphate have lessened the loss of nitrogen, gradually diminished the gain of ammoniacal nitrogen, and increased the gain of nitric nitrogen.Iron sulphate hinders the decomposition of nitrogenous matters, and favours nitrification. Using iron lactate with a soil containing sand, cla7, and calcium carbonate, the iron being in the same proportion as before, loss of nitrogen became 0.20 per cent., gain in nitric nitrogen increased to 22-34 per cent., and gain in ammoniacal nitrogen decreased to 3.57 per cent. Iron salts appear in general to be detrimental to the ferments destroying nitrogenous matters, but the organic salts of iron favour nitrification. Ferric oxide added to a complete soil (sandy, clay, and chalk) to the extent of 0.2 per cent.reduced the loss of nitrogen from 31.63 to 31.43 per cent., increased the gain of nitric nitrogen to 19.69 per cent., and reduced the gain of ammoniacal nitrogen to 10.71 per cent. Ferric oxide does not hinder the decomposition of nitrogenous matters ; it appears to moderate the energetic action of calcium carb- onate, and clearly to favour nitrification, by fixation of ammonia in the same way as clay, and by its oxidising properties. Calcium sulphate, when introduced to the extent of 0.5 per cent. in the same soils, is found to be superior to iron sulphate in regard to nitrification. In pure siliceous sand, the gain of nitric nitrogen is raised to 11-43 per cent., in sand with chalk to 13-67, in sand with clay to 23.67, and in a complete soil to 34.48 per cent.As a nitrogen preserver, its action is more efficacious than that of iron sulphate, except in the case of siliceous sand, an exception accounted for by its inferior solubility. Calcium sulphate does not retard the decomposi- tion of nitrogenous matters by ferments. Iron sulphate would be usefully employed to fix ammonia in positions where it is rapidly formed, as i n liquid manure ditches, manures, and sewage. Its use would be prejudicial in connection with organic manures which decompose but slowly, on account of its antiseptic properties. Iron sulphate would be ad-rantsgeously used as a manure in wet, sandy soils poor in clay, chalk, and ferric oxide. All other soils would be more benefited by the employment of' calcium salphate. Iron sulphate would be useless, if not detrimental, in the case of ferruginous soils.Chlorosis due to starving, and not to the influence of meteorolo- gical conditions or the ravages of parasites, might be overcome by the use of calcium sulphute as well as iron sulphate. 'l'he practice of adding natural mads containing gypsum is amply justified, as ammonia is fixed by the clay and calcium sulphate, the destruction of nitrogenous organic matter is lessened by the calcium carbonate and the losses of nitrogen diminished, nitrification is rendered regular, and the fixation of atmospheric nitrogen is much promoted. w. T.VEGETABLE PHYSIOLOGY AND AGRICULTURE. 1545 Formation and Oxidation of Nitrites in Soils. By S. WINO- GRADSKY (Compt. rend., 113, 89-92 ; compare Warington, Trans, 189 1, 484) .-Liquids containing ammonium sulphate and cjther mineral salts, together with magnesium carbonate, were sown with soils from various parts of the world.In all cases, nitrification started with the formation of nitrites, nitrates not appearing in quantity until the ammonia had disappeared. When, however, suc- cessive cultures were made from the soils, the later generations did not preserve the parallelism. With European soils, the formation of nitrates diminished after six o r eight generations, and at last ceased ; with soil from Quito, nitrites were still being formed after twelve generations ; whilst with other South American and African soils, the rate of formation of nitrates was not only maintained, but could be augmented by replenishing the solution with ammonium S l l t S .In the attenuated cultures, especially in those in which nifrates. had been formed, there were observed several kinds of microbes, which bore a general resemblance to the nitrous organism (nitro- monade). Some of these were isolated, and were found to retain under culture their power of osidising ammonia, but to lose after a few generations that of oxidising nitrites. An endeavour to isolate the nitric organism from Tunis soil by gelatin culture also gave negative results ; but the method by which the nitrous microbe had been isolated proved successful. A solution of nitrites was sown with Quito soil, and, aa soon as the oxidation had become regular, a little drop of the culture was sown in gelatinous silica. Colonies of two different organisms de- veloped, one of which proved to be the nit’ric microbe. It is a very small, irregular, bent rod, which bears no resemblance to the nitrous organism separated from the same soil.It rapidly converts solution of nitrites into nitrates, but has no action on ammonia. Organisms of similar function were found in the Java and Zurich soils, and it is probable that, like the nitrous organisms, they con- stitute a group, of which each soil contains a particular species. JN. W. Nitric and Ammoniacal Nitrogen as Manures. By PAQNOUL (Ann. Agron., l7,274--283).-Muntz has shown that plants receiving nitrogen only in the form of an ammonium salt can live in a sterilised soil in which nitrification of the ammonia does not take place, and hence concludes that ammonia compounds are directly assimilable by plants ; in ordinary soil, well provided with the nitrifying ferments, however, ammonia cannot persist, and plants must nearly always absorb nitrogen as a nitrate.The author’s experiments of 1890 011 this point were made in follr glass flower pots, holding 2-3 litres, and furnished with tubulures at the bottom, connected by india-rubber tubes to four small flasks, A layer of gravel was placed in each pot, and they were filled with the following media :- A. Good, arable soil containing, per cent., 0.102 N, 0.098 P206, 0.290 K207 and 1.5417 CaO. B, C, D. Siliceous sand, mixed with 10 grams calcium snlphate.1546 ABSTRACTS OF CHEMICAL PAPERS. C received in addition an admixture of 20 grams of the soil A, in order to supply it with the nitrifying ferments.Similar seeds were sown in the four pots, aud A WRS watered throughout with nothing but pure distilled water. B received at intervals 25 C.C. of a solution containing 100 milligrams N as ammonium sulphate, and 100 milligrams P,05 superphosphake. C received the same quantities of ammonium sulphate and super- phosphate as B, and, in addition, 100 milligrams of potash as potas- sium chloride in each 25 of nutritive liquid. D received in each 25 C.C. of solution 100 milligrams N as sodium nitrate, and the same quantities of superphosphate and potash salt as C. 20 estimations were made of nitric and ammoniacal nitrogen i n t,he drainage water of each flask at intervals, the nitric nitrogen by a colorimetric process witb diphenylamine, and the ammonia by distillation with magnesia, and Nesslerising.Nine cuttings of the crops were taken from May 14 to August 22, simultaneously in all the pots, and the total weights obtained were :- A. B. C. D. 31.7 59.5 106.3 103.1 grams. Thus the sterile sand, with suitable manures, gave much better yields than the good soil without manure, the organic nitrogen in the latter not being transformed into assimilable compounds with suffi- cient rapidity. In the presence of soil containing nitrifying ferments, the ammonium sulphate proved as efficacious as its equivalent of sodium nitrate, but the absence of this ferment reduced the yield to one-half. The results of analyses of the drainage waters on 20 different dates may be summarised thus :-In the drainage of pot A, the barest traces of nitric and ammoniacal nitrogen were found, generally about 0.2 milligram per litre.In that of pot D, which received altogether 1100 milligrams of N as sodium nitrate, mere traces of ammonia were present ; nitric nitrogen was found in large quantit-y (up to 110 miIIi- grams per litre) immediately after each fresh supply of the manurial liquid, but after eight or 10 days, or five or six percolations through the soil, the quantity sank to traces or nil, if the plant was in active growth. In the drainage of pot C, nitric and ammoniacal nitrogen were found in something like equal quantities on the whole set of estimations, so thak although i t is certain much of the ammonia was nitritied, it is not certain whether all the nitrogen that entered the plant was in the form of nitrate.In the drainage of B, large quanti- ties of ammonia were always found, and these increased towards the end of the experiment through accumulation of unused ammonium sulphate ; nitric nitrogen was either absent or present in traces only, except towards the end of the experiment, by which time a little nitrifying ferment may have got into the sand. Although the ammonium salt is shown to be far less favourable (in the absence of nitrifying ferments) to the vegetation than the nitrate, the consider- able crop obtained renders it extremely probable that some of it was directly assi mil ated .VEGETABLE PHYSIOLOQP AND RGRlCULTURE. 1547 Estimations of nitric and ammoniacal nitrogen in the plant itself were made on the cuttings of June 11 and 23 and July 7. The plant from A never contained nitrate, and the merest traces, if any, of ammonia ; in that from B, no nitrate was present, but there was a small proportion of ammoniacal nitrogen (13-14 milligrams per 100 grams j on each date ; the plants of C and D contained the merest traces, if any, of ammonia, but nitric nitrogen was present in very variable quantity, according to the time which had elapsed since the last supply of nitrogenous manure to the plant; 18 days after, the quantity was 3 and 8 milligrams per 100 grams ; seven days after, 140 milligrams per 100 grams.When supplied in abundance, nitrate is first stored in the plant and then its nitrogen is assimilated. The author’s experiments confirm the views of Muntz, already mentioned.J. M. EL. M. Loss of Nitrogen during Decomposition of Nitrogenous Organic Matter, and the Means of Limiting or Avoiding it. 32y J. H. VOGEL ( B e d . Centr., 20, 562-564; from J. .f. Landlo., 38, 32i-334).-According to v. Krause (J. f. Landw., 38, l), super- phosphate is an excellent preservative for manure, and is preferable to superphosphate-gypsum, owing to the greater amount of soluble phosphates it contains. With readily soluble phosphates, there seems to be a gradual formation of calcium carbonate and ammonium phosphate; the free acid takes up the ammonia, more quickly, but there remains only a small amount of soluble phosphates which fix ammonia. The author refutes these views of v. Krause. Small losses of soluble salts cannot be avoided with farm-yard manure.The loss of phosphoric acid is, however, slight, but may be considerable if super- phosphate is added t o it, SO much so that any beneficial action of the superphosphate is more than cancelled. Moreover, t,he soluble phos- phoric acid of the superphosphate, or superphosphate-gypsum, does not combine with the ammonia which is liberated from the farm-yard manure, but mostly goes over into the insoluble state: ammonium sulphate and sparingly soluble calcium phosphates are formed, with merely a, trace of ammonium phosphate. The very favourable effect of phosphoric acid in preserving manure is due, in the first place, to its power of so changing the fermentation that no free nitrogen, or but little, is formed. The liberation of nitrogen was shown by Dietzell to be prevented not only by phosphoric acid soluble in water, but also by phosphoric acid soluble in citrate, and the author has already proposed using a preparation which contains, besides calcium and tnagnesium sulphates, also a large amount of phosphoric acid soluble in citrate. The loss of free nitrogen, when gypsum is usedalone, is not nearly so great as the advantage which follows from the fixation of ammonia.Manuring Experiments with Rice. By 0. KELLNER, Y. KOZAI, Y. MORI, and M. NAGAOKA (Landw. Vel-suchs-Stat., 39, 361-382).- 111 order to ascertain the food requirements of rice, a number of experiments were made in which rice was grown in soil yariously N. H. M.1548 ABSTRACTS OF UREMIOAL PAPERS. manured. Wagner’s method of small plots was employed ; these were made by sinking wooden frames, with a surface of nearly square metre, about 50 cm. into the ground. The air-dried soil (which was of volcanic origin) contained :-Nitrogen, 0.608; phos- phoric acid, 0.448; potash, 0.232; and lime, 0.248 per cent. There were five fieries : the first contained six unmanured plots, three with nitrogen and potash, three with phosphoric acid and potash, and three with phosphoric acid and nitrogen. In the second series, all the plots had the same amounts of phosphoric acid and potash, and varying amounts of nitrogen. In the third series, all the plots had the same amount of nitrogen and potash, and varied amounts of phosphoric acid. In the fourth series, the amounts of nitrogen and phosphoric acid were the same in each case, and the potash varied. In- the fift,h series, all the p1ot.s had nitrogen, phosphoric acid, and potash, and different amounts of lime. The unmanured plots gave a very poor yield, and the application of much nitrogen and potash alone had no beneficial effect. Phosphoric acid was found to be a most important manure, whilst potash did little or no good. The results showed that, for its f u l l development, rice required a manuring of 7.5 kilos. of nitrogen and 12.5 kilos. of phos- phoric acid per one-tenth hectare; in some cases, a small amount of potaRh is necessary. The usual manuring of the district includes far too little phosphoric acid. With regard to the effect of the manures on the composition of the crops, it was found that the produce of the unmanured plots, and of those which had nitrogen and potash, was the richest in nitrogen. The produce poorest in nitrogen was obtained from those plots which were manured with much phosphoric acid and potash, but with little or no nitrogen. When much nitrogen was applied, the total d v produce contained more than 1 per cent. of nitrogen, the excess being chiefly in the straw. The differences in the amounts of phosphoric acid in the produce of the different plots were generally ana.logons to the difference in the amounts of nitrogen. When no nitrogen, but much phosphoric acid was applied, the straw remained poor in phosphoric acid ; this is ascribed to the quick ripening of the plants. N. H. M.

1548 ABSTRACTS OF UREMIOAL PAPERS. A n a1 y t i c a 1 C h e m i s t r y. The True Litre or Mohr‘a Litre, for Volumetric Analysis. By W. FXESENIUS (Zeit. and. Chem., 30,461-465).-The expressed desire that the German Imperial Standards Commission should undertake to test and certify measuring vessels for chemical purposes has brcught into prominence the question whether the true litre ought to be used for this purpose, or the very prevalent ‘‘ Mohr’s litre,” which is about 2 C.C. greater than the true litre. The Commission, nlthougb holding itself bound bythe terms of its constitution not toANALYTICAL CHEMISTRY. 1549 authenticate as a litre measure any vessel which did not conform to the hue definition, nevertheless took steps to ascertain the opinions of various scientific men with regard to the question.In view of t h e common practice of expressing the specific gravities of liquids with reference to water of the same temperature (and that a mean working temperature) as unity, which practice is already recognised by the Commission in testing hydrometers, and considering the con- venience of expressing the unit of weight and that of volume by an identical number under practical working conditions, as well as the confusion which would result from neglect of the corrections rendered necessary by the employment of " true " litre vessels at any tempera- ture other than O", the author suggests that Mohr's litre should be retained for volumetric work, and that the certificate to be issued should be worded in some such manner as the following :-" The flask X, filled with water of 17.5" C., so far that the mark is tangent to t h e lower meniscus, contains an amount of water which equipoises a brass kilogram in air of 760 mm.pressure, and therefore holds a so-called Mohr's litre." M. J. s. Neutral Litmus Paper. Ey K. MAYS (Verh. d. Nutwhist.-Med. Verein Heidelberg, N.F.. 3, 295--298).-An aqueous extract of com- mercial litmus is acidified with hydrochloric acid, and placed within a parchment paper dialyser for eight days, there being running water outside. Litmus is a colloi'd substance, and in this way is freed from saline and other impurities. Paper impregnated with this neutral litmus solution is perfectly satisfactory for the determination of' reaction. W. D. H. Test for Hydrogen Peroxide.By G. DENIGI~S (Bull. SOC. Chim. [3], 293).-When a drop of a 10 per cent. solution of metaphenylene- diamine chloride is boiled with a few drops of water and a drop of hydrogen peroxide solution, a carmine-red coloration is produced. This reaction will detect 0.005 milligram of hydrogen peroxide in a drop of water, but is affected by the presence of nitrites. The test is thus modified, to be independent of the presence of the latter compounds :-One or two drops of metaphenylenediamine chloride is added to 1 C.C. of ammonia solution containing a few drops of hydrogen peroxide solution ; the mixture is boiled for some minutes, when the previously colourless solution becomes blue, of intensity corresponding with the peroxide present ; addition of alkali hydroxide solution changes the colour to red.In reference to a former corn- munication (Abstr., 1890, 1185), the author states that the molybdo- sulphuric acid used for the detection of hydrogeu peroxide is made by mixing equal volumes of a recently prepared ammonium molybdate solution (10 per cent.) and concentrated sulphuric acid ; the solation, which becomes bluish on keeping, is rendered colourless by warming, and its sensitiveness is unimpaired. Estimation of Sulphur in Iron. By v. REIS and F. WIGQERT (Chsnz. Centr., 1891, ii, 218-219; from Stahl u. Eisen, 11, 480-483). -The apparatus employed by the authors is represented in the T. G. N.

A is a distillation flask, on the side-tube of which a Rmall bulb B is blown, from which a side-tube leads to the absorption apparatus C.The stoppered funnel D has a ground stopper on the lower limb, which fits the neck of A. E is a small washing flask for the carbonic anhydride, which is supplied from a cylinder of liquid carbonic anhydride. The absorption liquid consists of equal parts of hFdrogen peroxide and dilute (1 : 4) ammonia. The sulphuric acid which may be present in the hydrogen peroxide is previously precipitated ssactly by the addition of barium chloride, the barium sulphate is allowed to settle, and the clear solution of per- oxide siphoned off. C should be of such dimensions that 1 litre of gas may be drawn through it in 3.5 minutes. 10 grams of the iron or steel is introduced into A, the tap of D opened, and carbonic anhydride allowed t o flow into the apparatus, which forces the hydrochloricacid from the funnel into the flask, after which the tap of D is again closed.I n the case of steel, a small fla,me may be at once applied to the flask A ; for iron 2-3 minutes should be allowed to elapse before heating. I n about 5 minutes, the liquid is brought to boiling, and carbonic anhydride is then allowed to flow rapidly through the apparatus for 20 minutes. The conteiits of C are now transferred t o a beaker, and C is rinsed with 100 C.C. of water, the total volume now measuring 20@ C.C. It is boiled for 2-3 minutes, 10 C.C. of dilute 1 : 1-hydrochloric acid added,ANALYTICAL OHEMISTRY. 1551 and boiled again to expel all carbonic anhydride. 10 C.C. of ammonia.sp. gr. 0.96, is added, together with 2 or 3 drops of methyl-orange, and if the liquid should still be acid, II little more ammonia is added, and tthe liquid is now neutralised very carefully with hydrochloric acid, so that t.he methyl-orange is not red, but only orange-coloured. It is now heated to boiling, 10 C.C. of barium nitrate solution (70 grams i n 1000 c.c.) added, again heated to boiling, 10 C.C. of dilute hydrochloric acid added, and the precipitate allowed to settle while warm. After 15 minutes, it is collected, washed with hydrochloric acid and water, and the filter is placed in a porcelain crucible, charred in a muffle, and ignited for 15 minutes at a red heat. The whole determination lasts about two hours. The authors have found that the barium sulphate, i f precipitated with barium nitrate from an exactly neutral liquid, and in the absence of metals, is Fery dense and easily filtered.The use of a mechanical stirrer still further shortens the time. J. W. L. Sulphuric Acid in Plastered and Natural Wines. By D. VITALI (L’Orosi, 14, 145--163).-Roos and Thomas (Compt. rend., 111, 575) concluded that plastered wines contain normal potassium sulphate, because on adding ammonium acetate to the wine, precipitating the sulphuric acid with barium chloride, and igniting, the whole of the chlorine is found in the residue, whereas if an acid sulphate were present, some of the chlorine would be volstilised as ammonium chloride. The author finds, however, that under the above conditions ammonium chloride reacts with the potassium and calcium tartrates in the wine, so that the whole of the chlorine is fixed and remains in the ash.The presence of acid sulphates in plastered wines may be demon- strated by treating them with some alkaloid, such as quinidine, which is capable of extracting sulphuric acid from potassium hydrogen sulphate but has no action on the normal salt. The experiment is conducted as follows : an excess of freshly precipitated quinidine is added to the wine(3 parts) until its red colour is changed to a violet- blue, the whole briskly shaken, heated for a short time at 50-60”, chloroform (2 vols.), and sufficient, absolute alcohol to difisolve it added, and then, without shaking, a volume of water about half the volume of the mixture is also added. After a time, the clear chloro- form solution is drawn off, evaporated, and the residue tested for sulphuric acid.By the above method, the author has also succeeded in proving the preseiice of acid sulphates in the urine. The presence of nitric acid in wine may also be detected by treating it with quinidine as above, evaporating the chloroform solution, treat- iug the residue with water and potassium carbonate, t o convert the nitric acid into potassium nitrate ; this remains undissolved on treating the mass with alcohol and chloroform, and may be identified by the ordinary methods. S. B. A. A. Estimation of Small Quantities of Boric Acid. By F. PAR- MENTIER (Compt. red., 113, 4143).-The method is based on the difference in the behaviour of helianthin and litmus or orcein 5 b 21552 ABSTRACTS OF OHEJlICdL PAPERS.towards boric acid and its salts. Yellow (alkaline) helianthin is not affected by boric acid or borates, whilst alkaline litmus, or, better, orce'in, changes colour when the base is partially or entirely saturated. When the alkali is soda, the point is that at which the biborate is formed. To estimate the boric acid in a mineral water, the residue, after re- moval of the silica., is dissolved in hydrochloric acid, and treated with ammonium nitrate and ammonia, to precipitate the iron, alumina, manganese, and arsenic and phosphoric acids. The filtrate is then acidified with hydrochloric acid, and divided into two equal portions, both of which are titrated with sodium carbonate, one with helianthin as indicator, the other with orcein.In thi8 way quantities of boric anhydride as minute as 1-8-3.8 milligrams per litre have been found in the waters of Royat.

Ckem., 30, 452-460).-When a solution containing much calcium with little barium, and feebly acidified with hydrochloric acid, is precipitated with a quantity of sulphuric acid only a little greater than is required to form barium sulphate with the barium present, the whole of the barium is not precipitated, although the precipitate retains some calcium, even after washing until calcium is no longer to be detected in the washings.If, on the other hand, six times a8 much sulphuric acid is added a s corresponds with the barium present, the whole of the barium is indeed precipitated, but calcium is also thrown down, even when the amount of water present is nearly double that required to hold all the calcium sulphate in solution. In presence of a large quantity of hydrochloric acid, barium can be precipitated with approximate completeness only when much sulph- uric acid is added. Thus, 4C0,OOO parts of a liquid containing 1.2 per cent. of bydrogen chloride and 0.38 per cent. of sulphuric- anhydride was required to dissolve 1 part of barium sulphate, whilst with the same strength of hydrochloric acid, but with siilphuric acid only slightly in excess of the barium present, the solubility was 1 part in 18,000.With a large excess of both hydrochloric and sulphuric acids, the separation of barium and calcium seems at first. to be accurat.e, and is, in fact, better than with feebly acid liquids ; it is, however, still imperfect. Diehl's method of separating the two bases, by digesting t'he mixed sulphates with a concentrated solution of sodium thiosulphate, gives approximately accurate results when the two sulphates have been precipitated separately and then mixed, though zlr little barium is lost, since barium sulphate is not absolately insoluble in strong thiosulphate solution. When applied, however, to the sulphates precipitated simultaneously, a considerable amount of calcium sulphate remains undissolved.

VORTMANN (Bey., 24, 2749- 2765).-The metals are best obtained in the form of amalgams, by adding to the solution the corre- sponding salt to be examined, and a weighed quantity of mer- curic chloride; in the case of acid solutions, pure precipitated mercuric oxide may be employed. At the commencement of the operation, ft current giving 6-8 C.C. of oxyhydrogen gas per minute is employed ; when the metal begins to be deposited, this is reduced to one giving 2-3 c.c., and, as the analysis proceeds, the current is gradually increased fo its original strength. Mercury alone is quan- titatively precipitated by electrolysis from solutions containing ammonium oxalate, ammonium tartrate, or alkaline sodium sulphide.After the deposition of mercury from solution in potassium iodide, it is needful to dissolve the iodine deposited on the positive electrode in soda and continue the electrolysis for an hour, or if the quantity of iodine is very small, it may be suBicient to wash the metal quickly with sodium sulphite solution. Mercury can also be deposited from an alkaline solution of potassium mercuric iodide; in this case, the metal should not be washed with alcohol, or particles will become detached. Zinc is best deposited from solutions containing ammonium oxalate or from ammoniacal solutions; in the first case, not more than 2-3 parts of mercury should be added for 1 of zinc, but in the latter solution, the proportion should be at least 3 parts of mercury to 1 of zinc.As the platinum vessel is attacked during the operation, it is advisable either to deposit the zinc directly and not as an amalgam, or to employ a dish coated with copper or silver. The determination of cadmium resembles that of zinc ; on account of the sparing solubility of cadmium oxalate, it is best to employ an ammoniacal solution, unless the quantity of cadmium does not ex- ceed 0.2-0.3 gram; there should be 6 6 parts of mercury to 1 of cadmium. The deposition of lead from acid solutions is effected by dissolving the lead salt, together with mercuric chloride, in water, adding sodium acetate and a little concentrated potassium nitrite solution, the re- sulting precipitate being dissolved by the addition of acetic acid ; the formation of any lead oxide towards the end of the operation can be prevented by the addition of small quantities of potassium nitrite.The lead amalgam is stable when dry, but in presence of moisture is quickly oxidised on exposure to air. Lead is also deposited quanti- tatively from alkaline solution; as the use of alcohol to dry the amalgam would cause loss, oxidation takes place, and consequently the results are somewhat high. The method affords, however, tlr ready means of separating lead from other metals, such as tin, antimony, or arsenic, and for this purpose it is converiient to employ an ammo- niacal solution containing tartaric acid ; when all the lead is depo- sited, the supernatant liquor is poured off, the amalgam dissolved in acid, and the solution treated as above described.Bismuth is best determined in hydrochloric acid 'solution, the precipitation of basic salts being prevented by the addition of excess of potassium iodide, or by dilution with ethyl alcohol mixed with 2 parts of water. The second method is much better if bismuth is1554 ABSTRACTS OF CHEMICAL PAPERS. present. The amalgam is stable, and may he heated at 90' in an air-bath without suffering any change. Should the bismuth be dk- solved in nitric acid, not less than 4 parts of mercury t o 1 of bismuth should be present, and i t is necessary to add tartaric acid. The quantitative deposition of bismuth from ammoniacal solutions con- taining tartaric acid is unsatisfactory, but affords a nsefnl means of separating it from tin, antimony, and arsenic.Antimony is first oxidised to an tirnonic anhydride and then dissolved in soda and sodium sulphide ; 2 parts of mercury to 1 of antimony must be present. As antimony is not precipitated from ammoniacal solutions containing ammonium tar- trate, such a solution may be used to separate it from lead and other metals, whilst, the first, method enables it to be separated from tin. No means have yet been discovered of determining arsenic in the form of its amalgam ; during electrolysis, considerable quantities of arsenic hydride are evolved, and hitherto attempts to decompose this at the moment of its formation have proved fruitless. Arsenic amal- gam undergoes no change on exposure to the air.J. B. T. Antimony Pentasulphide : Separation of Arsenic and Antimony. By T. WIm (Zeit. anrrl.

LEIDIB (Compt. rend., 112, 1259--1261).-Osmium and ruthenium are removed in the form of volatile compounds, and iridium is removed by treatment with lead. A moderately dilute hydrochloric acid solution of tbe remain- ing metals is heated to about 60" and mixed with potassium nitrite. If much platinum is present, potassium platinochloride gradually separates as a crystalline precipitate quite free from other metale. After cooling and separation of this salt, the liquid is again heated and further quantities of nitrite added.Suddenly, and especially if the liquid is stirred, the crystalline double rhodium compound sepa- rates, carrying with it lead, bismuth, and tin, and small quantities of copper. i f the liquid is allowed to cool, the separation of the rhodium becomes complete, provided that a moderately large quantity of potas- sium chloride is present. Should iron and copper be present, the addition of the nitrite is continued until the liquid becomes alkaline, and, on boiling, the iron and copper are precipitated, whilst platinum and palladium remain in solution. Water Analysis. By C. LEPIERRE (Bull. SOC. Chim. [3], 5, 299- 307).-A criticism of Routron and Boudet's method for estimating hardness. The author describes the preparation of standard almond oil soap solution such that 1 C.C.corresponds with 1 milligram of dissolved calcium chloride, and records experiments and the calculated equivalent values for other calcium and magnesium compounds. Contrary to Wanklyn and Chapman, he states that magnesian waters do not require 16 times their calculated equivalent of soap solution for complete precipitation, but that the amounts required are the same as with calcium solutions of equivalent strength. It is only with solutions containing between 20 and 30 grams of calcium chloride (or The amalgam is very stable. C. H. B.ANALYTICAL OEEMISTRT. 1555 its equivalent in other calcium or magnesium salts) per litre that the soap solution required is directly proportional; both weaker and stronger solutions require relatively more soap solution.Tables are given for calcium salts and magnesium salts.

Erlangen, Heft ii).--G uaiacum-copper sulphate paper is a very untrustworthy test. It is much better to add to the suspected distillate in a basin a drop of freshly made guaiacum tincture and then a drop of copper sulphate. To detect cyanides in presence of ferrocyanides, the substance should be mixed with tartaric acid, then gradually made feebly alkaline with sodium carbonate, and treated with a current of carbonic anhydride in a distillation apparatus at it temperature not exceeding 60", and the distillate tested. All metallic cynnogen compounds are decomposed by carbonic anhydride at 100" ; but ferrocyanides and ferricganides not below 80°, whilst the simple cyanides, including mercuric cyanide, are decomposed between 50" and 60".M. 5. S. Detection of Turkish Geranium Essence in Oil of Roses. By G. PANAFOTOW (Ber., 24, 2700-2701).-Oil of roses from Soutli Bulgaria and Turkey is very oFten adulterated with Turkish geranium essence (Indris Yaghi) ; the prcsence of even traces of the latter can, however, be easily detected, since a mixture (2 to 3 drops) of the two oils gives a blue coloration on shaking with a solution of rosaniline previously decolorised with sulphurous anhydride, and then keeping for about two hours. Pure oil of roses gives a red coloration after shaking with the reagent and then keeping for about 24 hours.When Turkish geranium essence is mixed with an equal quantity of concentrated sulphuric acid on a watch glass, a considerable de- velopment of heat occurs, and dense, white fumes, having a tarry odour, are evolved ; on adding 95 per cent. alcohol to the brownish-red mixture, a yellow, fatty, flocculent substance is precipitated, and t.he solution, which is at first red, changes to yellow on keeping for some time. Oil of roses also gives, with concentrated sulphuric acid, a hrownish-red solution, but, on the addition of alcohol, a clear, almost colourless solution is obtained. This difference in behaviour can also be made use of for the detection of geranium essence in oil of roses. F. S. K. Estimation of the Impurities in Alcohol by Rose's Method. By A.SCALA (Gaxzetta, 21, 346-374).-The author gives a summary of our knowledge of the impurities present in commercial spirits, and then details experiments made to determine the trustworthiness of Rose's method of estimating the quantity of fuse1 oil present. The experiments on the increase of volume experienced by chloro- form, when agitated with spirit containing amyl alcohol or other ordinary impurities, are carried out in a stoppered glass cylinder of the form usually employed, having a capacity of 150 c.c., and a scale graduated i n twentieths of a C.C. This is washed first with concen- trated sulphuric acid, then with nitric acid, and finally with water, and1556 ABSTRACTS OF CHED5IGAL PAPERS. well dried ; a little more than 20 C.C.of carefully purified chloroform is then put in, by means of a long-stemmed funnel, and the cylinder left in a bath until it has attained a temperature of 15O; the excess of chloroform is now taken out, leaving exactly 20 C.C. Meanwhile, pure alcohol has been diluted to a strength of 30 vols. per cent., the re- quired quantity of impurity added, and the strength again reduced to 30 vols. per cent. by addition of water or alcohol; 100 C.C. of this spirit is now put into the cylinder, together with 1 C.C. of sulphuric acid of density 1.286, all being kept a t the standard temperature. After well agitating, the cylinder is returned to the batjh, and the volume of the chloroform read off after 20 minutes. The unit, from which the augmentation in volume of the chloroform is to be calculated, is obtained by performing the test wifh pure dilute alcohol of the standard strength, namely, 30 vols.per cent., and is 21.59 at the standard temperature. Consequently, this number must be subtracted from the volume obtained when operating with an impure spirit, in order to obtain the increase in volume due to the impnri ty . A variation of If 1 vol. per cent. in the strength of the alcohol em- ployed is attended by a variation of k0.26 C.C. in the volume of chloroform obtained. A rise of temperature of 1" increases the volume of chloroform by 0.036 C.C. on the volume a t 15", but if the unit volume, that is to say, the volume which 20 C.C. of chloroform occupies after agitation with 100 C.C. of 30 vols. per cent. alcohol, be determined at temperatures other than 15", the increase in volume due to fuse1 oil is practically a constant for other temperatures. The results of nn examination of the effect on the volume of the chloroform of other substances which might occur in spirits are em- bodied in the following table.The numbers give the increase in volume, over and above the unit volume, due to the presence of 1 C.C. of the corresponding substance in each 100 C.C. of 30 vols. per cent. spirit.

The increase in voliinie of the chloroform is directly proportional to the quantity of fuse1 oil present, and the author gives a table obtained by interpolation, from which the quantity present is deduced directly from that increase. By previous distillation of the spirit with a few drops of potasb, most of the acetaldehyde and furfuraldehyde is retained by the potash,AKALY TICAL CHEMISTRY. 1557 but the proportions of the other inipurities present are practically un- altered by this treatment. The author considers that this method for the determination of f use1 oil is quite satisfactory if cmployed with the precautions detailed above, but that its indications are not to be depended on in the case of those liquors of which aromatic essences in quantity are essential con- stitue nts.W. J. P. By L. C A R I ~ ~ (Conzpf. rend., 113, 139- 141).-10 grams of pure phenol is dissolved in 1000 C.C. of water, and from this solutions are prepared containing 5.0, 3.0, 2.0, 1.0, 0.8, 0.6, 0.4, 0.2, and 0.1 gram of phenol per litre. The phenol solution to be examined, if concentrated, is diluted with 10 times its volume of water. 25 C.C. of the solutiou is placed in a conical flask wit,h 5 C.C. of nitric acid, and equal quantities of the standard solutions of phenol are treated i n a similar manner, all the flasks being heated in the same water-bath for one or two hours.‘l’he intensity of the coloration produced is proportional to the quan- tity of phenol present. Greater accuracy is obtained if: after the nction has ceased, the solutions are mixed with 20 C.C. of sodium hydroxide solution and diluted to exactly 50 C.C. The liquids are filtered, and compared by means of the colorimeter. If alcohol is present, the action of heat must be continued until all the alcohol has been expelled; if the quantity of alcohol is consider- able, the liquid must be diluted, in order to avoid the formation of ethyl nitrite, In the case of impure phenol, the heating must be con- tinued until all tarry products are destroyed. As a rule, the termina- tion of the reaction is indicated by the disappearance of the turbidity fbat was produced by the addition of the nitric acid.Estimation of Sugar and Tannin in Wines. By J. H. VOGEL (Beit. ang. Chem., 1891, 44--69).-The author has proved by several experiments that it is absolutely necessary to first remove the tannin and colouring matters before attempting to estimate the sugars by Fehling’s solution. 25 C.C. of a 1 per cent. solution of tannin gave an amount of metallic copper corresponding with 0.91 per cent. of sugar. As the amount of tannin in Portuguese wines often is as high as 3 per cent., the importance of fully removing the tannin will be readily understood. After a short treatment with an insuffi- cient amount of animal charcoal, the tannin is removed before the colouring matters are precipitated, and this fact enabled the author t o prove that these colouring matters exercise a powerful reduction on the Pehling’s solution, as the yield of copper became greater as the solution was more coloured.Their removal is best effected either with animal charcoal or basic lead acetate, but the author has made several important observations. As to the use of lend solution, 3 C.C. is supposed to be sufficient for 60 C.C. of Rhine wine, whilst for red wines, the amount must be doubled. But in the case of Por- tuguese wines, this amount is far too small, and the author has met with a sample which required three times its bulk of ZiquorpZumbi before it was completely decolorised. The excess of lead must be removed, according to Bmth, by sodium carbonate, but the lead Estimation of Phenol.C. H. B.1358 ABSTRACTS OF CHEMICAL PAPERS. separates slowly, causing afterwards an increase in tke weight of tlic copper precipitate, and unless the filtration has been very carefully effected, the sugar may come out from 0.2 to 2.2 per cent. too high, tbe error increasing with the amount of lead solution used. F o r wines rich in tannin and colouring matters, the charcoal process is the best. If, for this purpose, powdered purified animal charcoal is wed, ‘25 grams of the charcoal will be found sufficient for 200 C.C. of wine. The time the charcoal is allowed to act varies from 13 to 60 minutes, accordiug to the amount of colouring matters present. A little sugar is also absorbed by the charcoal, but the author, who has thoroughly investigated the matter, finds the amount never to exceed 0.3 per cent.under the most unfavourable conditions. I n some cases, it is advi- sable to first dilute the sample with a known volume of water before attempting to decolorise with the charcoal. The author next inves- tigated the two chief processes used for the estimation of the tannin. I t must be borne in mind that this acid, as it occurs in wines, i s not at all a def~nite chemical compound, and is not identical with gallo-tannic acid. The percentage found by analysis is therefore not the true one, but only expresses its equivalent in gallo-tannic acid. The process which was found to answer best was that of Lowenthal. According to this method, the solution containing the tannin is largely diluted with water, mixed with a definite quantity of solution of indigo- carmine, containing sulphuric acid, and then titrated with a weak solution of potassium permanganate. Operating on a known quantity of tannin, and deducting the permanganate necessary for the oxidation of the indigo ahme, the exact strength of the perman- ganate expressed in tannin is of course obtained.I n applying the process to wine, which of course contaius many other organic matters, also oxidisable by permanganate, the author proceeds as follows: ‘LO C.C. of the sample is mixed with 2 litres of rainwater, 20 C.C. of solution of indigo-carmine (30 grams per litre), and 10 C.C. of sulphnric acid. A solution of potassium permanganate (1 : 1000) which has been carefully standardised is now run in until the liquid just loses its green, and changes to a bright-yellow, colour.To obtain the amount of permanganate absorbed by the organic matter, 50 C.C. of the sample i.s mixed with 100 C.C. of a, solution of gelatin (1 : lOOO), and 60 C.C. (= 20 C.C. of original sample) is filtered off, and again titrated. The difference between the two titrations represents the true amouut of tannin. The permanganate absorbed by the excess of the gelatin varies but slightly, but may be put down as 0.2 C.C. As regards the process depending on the precipitation of the tannin by an ammoniacal solution of zinc acetate, previous to titration, the author found it to give results far too high and gene- rally untrustworthy, even with solutions of pure tannic acid. Estimation of Cane Sugar in Soap.€37 J. A. WXLSOX (Chenz. News, 64, 28--29).-The following method is found to be satisfac- tory :-A satiirated solution of magnesium anlphate is gradually added and stirred into 10 grams of soap dissolved in 150 C.C. of water at 80°, and the magnesium soap is washed on a filter with hot water containing a small quantity of magnesium sulphate. The filtrate and washings, L. DE E.ANALYTICAL CHEMISTRY. 1339 after almost neutralising wit,h dilute nitric acid, are evaporated t o 40 c.c., and, when cool, acidified with dilute nitric acid, treated with a few drops of basic lead acetate and 2 C.C. of alumina emulsion, diluted to 50 c.c., and the solution polarised in a 200 mm. tube. Examination of Urine for Sugar. By E. Lumm (Chem. Ceitti-., 1891, ii, 90-91; from Centr.med. Wiss., 1891, 357--358).--The author has employed Molisch's farfuraldehyde reaction, as improved by Udrariszky, for determining the sugar in urines (Abstr., 1888, 863, 878). He finds that a 0.1 per cent. solution of sugar gives the colonr reaction and spectrum immediately ; a 0.2 per cent. solution gives the coloration faintly after shaking several times, the violet colour passing later into a, red. One drop of the undiluted urine is first, tested, and i f i t gives the furfuraldehyde reaction, i t is diluted until the lowest limit, representing a 0.02 per cent. solution, of sugar is reached, from which the amount of sugar present may be calculated. The naphthol test only indicates, however, the presence of carbo- hydrates generally, and, since gum is present in uiines, the author makes a second determination after allowing the sugar to ferment with yeast, the difference between the total carbohydrates and the gum being grape sugar.I n the case of diabetic urines, the amount of sugar, as determined by this method, is higher than if determined by either titratiori or polarisation. From a large number of determina- tions of sugar in urines, the author concludes that grape sixgar is present in all urine, the amount found in that of adult persons being about 0.1 per cent., and varies according to the quality and quantity of the food, and depends also on the length of time which has elapsed since the meal. The total carbohydrates amount to 0.2 per cent. The kidneys possess the power of allowing sugar t o pass in a slight degree, which is increased by those circumstances which cause an increase in the amount of sugar in the blood.It is for this renson that the urine of lying-in women contains relatively moro milk sugar than usual. J. W. L. Babcock Method for Estimating Fat in Milk. By F. T. SHUTT (Chem. News, 64, 3--4).-1n the author's hands, the Babcock method for estimating fat in milk yielded fairly accordant results in duplicate experiments ; but, in comparison with gravimetric analysis, the resulis were somewhat low; tho maximum deficit recorded is, however, 0.25 per cent. I n applying the method, the sulphuric acid is added to, and well mixed with, the milk, and, while still hot, the mixture is centrifugalised in the machine, which is also kept hot with hot water.Hot water is then added, and the amount of fat noted immediately a t the close of the operation. Reactions of Olive Oil. By G. DE NEGRI and G. FARRE (Chem. Centr., 1891, ii, 87-88).-After an exhaustive examination of a large number of samples of olive oil of known purity, the authors 6nd (a) the iodine " number " is slightly higher for oils derived from mature than from immature olives, whilst the reverse is the case with regard D. A. L. D. A. L.1560 ABSTRACTS OF CHEMICAL PAPERS. to the age of the oil ; also, the mode of manufacture has an influence on this test. On the other hand, the locality of growth has LIO influ- ence on the iodine test, whilst the variety of olive influences the iodine-absorbing quality of the oil, and the " number " rises to 88 in some cases.The specific gravity is almost constant, varying only from 0.916 to 0.918 at 15". The free fatty acid of the oil melts at 24-27" and solidities st 17-22", the determinations being made with samples obtained by pressing the olive ; the fatty acids of oil obtained by extracting the olives with carbon bisulphide or ether melt at 25-29" and solidify a t 22". The '' saturation equivalent " (milli- grams of KHO required to saponify 1 gram of oil) varies from 185 to 196, and is 190 for most samples. Tho temperature of a iilixture of olive oil and concentrated sulphuric acid was nearly con- stant at 35", the lowest reading being 32" and the highest 57". The pure oil does not give any peculiar colorations with those reagents which are usually employcd for distinguishing oils ; those oils, how- ever, which are obtained from immature olives, 0 1 9 which are extracted by carbon bisulphide, give colour reactions of an indefinite character- Estimation of Fatty Matter in Turkey-red Oil (Olehe).By R. WILLIAMS (Chem. News, 64, 13--16).-The volumetric method, heating with dilute acid and Rome salt solution on the water-bath, adding more hot salt solution, and then reading the volume of fat when cold, gives results 2 to 4 per cent. too high, whereas low results are obtained by the Wilson method, in which the oil mixed with brine and hydrochloric acid is extracted twice with ether, the mixed extracts evaporated, and tho residue dried by means of dry air, absolute alcohol, and heating. The author has obtained satisfactory results with the wax method in the following manner :-200 grains of the sample is warmed with 50 grains of 10 per cent.hydrochloric acid and 300 grains of saturated salt solution, warmed gently for a few minutes, 200 grains of wax added, and the whole heated until perfectly liquid. After cooling €or some hours, the cake of wax is removed, washed with saturated salt solution, then with a little cold water, dried first with filter paper, then either over sulphuric acid in a desiccator or by heating not above 160" F. and atirring. The weight, less dish and wax, gives the quantity of fat. D. A. L. J. W. L. Lard and its Adulterations. By H. W. WILEV (Zeit. maZ.

The chief adulterants are beef tallow and cotton-seed oil. Bechi's silver nitrate test, Maumen6's sulphuric acid reaction (Abstr., 1889, 319, 320), and the microscopic examina- tion of the crystals from ethereal solution (Absti.., 1890,428) are all recommended. The author's method of determining the melting poi0 t of a fat is described, and the apparatus figured (compare Abstr., 1888, 93). M. J. S.ANALYTICAL OHEh118TRY. 1561 Estimation of Urea. By K. A. H. M~RNER and J. SJOQUIST (Chem.Centr., 1891, ii, 230-231, from Centr. Physiol., 5,150-152). -To 5 C.C. of the urine in a flask, 5 C.C. of R saturated solution of barium chloride containing 5 per cent. of barium hydroxide is added also 100 C.C. of ether-alcohol (2 parts of 97 per cent. alcohol to 1 part of ether), and the mixture is allowed to remain in the closed flask until the following day; the precipitate is filtered off and washed with ether-alcohol. The ether-alcohol is separated from the filtrate at a temperature of 55" (not exceeding SOo), by meaus of a current of air at low pressure being passed through the liquid. When the volume is reduced to 25 c.c., a little water and some magnesia are added, and the evaporation continued until the distillate shows no alkaline reaction. The residual liquid, measuring from 15-20 c.c., is treated with a few drops of concentrated sulphuric acid and evapo- rated on the water-bath, after which the nitrogen in it is determined by Kjeldahl's method and calculated into urea.J. W. L. Reactions of Cocashe and of Ecgonine. By D. VITALI L'Orosi, 14, 1--19).-1f a barely visible particle of coca'ine is placed in a porcelain capsule, covered with 0.5 to 1 C.C. of concentrated sulphuric acid, stirred until solution is complete, and a quantity of potassium or sodium iodate or iodicacid twice or three times as great as that of the cocaine taken is added, and the whole gently heated with great care on the water-bath, the liquid soon exhibits striations of a, bright green colour, which, on continued heating, changes to grasa-green, and subsequently into blue ; on raising the temperature, the liquid becomes violet, and violet fumes are evolved.This reac- tion is very sensitive, and is obtained very clearly with 0.00005 gram of the hydrochloride ; with very careful working, 0*00002 gram of tohe base may be recognised. The action of sulphuric and iodic acids on a large number of alkaloids has been investigated by the author, and from the results, which are given at length, it appears that whilst many alkaloids, as for example, thebaine, atropine, chelidonine, coridaline, &c., exhibib highly characteristic colonr changes, only caff e'ine and theobromine give the same sequence of chromatic effects when the test is made as described for coca'ine. If, however, the quantity of iodic acid used is not too small, the greenish o r bluish-green coloration exhibited by these alkaloids is not followed by any violet coloration, as in the case of cocaiue.Traces of beuzoic acid behave with sulphnric and iodic acids exactly like coca'ine, and the bcharionr of the alkaloid is probably due to its decomposition by sulphuric acid with the formation of some benzoic acid. Ecgonine gives under the same conditions a yellow coloration, which quickly changes to bright red, and finally to brown. On adding a drop or two of a dilute sulphuric acid solution of potassium permanganate (0.5 per cent.) to a little cocaine dissolved in a few C.C. of concentrated sulphuric acid, a violet coloration i s obtained which disappears on agitation, and reappears on adding more of the reagent.With ecgonine, a yellow coloration is given by the first few drops of the reagent, and subsequent additions produce a violet coloration, which is more stable than that obtained with cocaine,1362 ABSTRACTS OF CHEMICAL PAF'ERS. A solution of iodine in potassium iodide affords a ready mean8 of distinguishing cocaine from ecgonine. With the former, a reddish- brown precipitate is formed, consisting of microscopic, perfectly spherical, black globules ; ecgonine likewise yields a reddish-brown precipitate, which, however, becomes crystalline in a few minutes, forming microscopic tufts of reddish-yellow, rhombic tables or prisms. No crystallisation is obtained if the dilution of the solution is more than 500 to 1. Ecgonine may be recognised by this test in the extracts from animal remains ; urine must, however, be tested directly by placing a drop on tt glass slip, adding one or two drops of the reagent, allowing it to evaporate almost to dryness, and examining under the microscope.Tho urine must contain at least 1/600 of ecgonine. From further experiments made by the author, it appears that coca'ine is not affected by prolonged contact with putrefying animal remains, and that, when taken internally, it is almost entirely decomposed within the system, only a very small proportion passing into the urine.

The colorations and precipitates are not due merely to the reducing power of the alkaloids, as Lafon SUPPOSES, for narceine produces a much more rapid precipitation of selenium than does morphine, although the latter is the more powerful reducing agent of the two.C. H. B. Extraction of the Colouring Matter of Wines. BY L. HUGOUNEXQ ( J . Pharm. [ 5 ] , 24, 51-53).-A 10 per cent. solution of tartaric acid is neutralised with a slight excess of ammonia ; to this is added normal lead acetate until the lead precipitate just begins to be permanent. After a time, this solution is filtered and added to the wine, previously neut.ralised by ammonia, as long as a precipitate forms. This precipitate is washed, suspended in a small quantity of 80" alcohol, and a 15 per cent. solution of sulphuric acid added drop by drop, excess being avoided. The solution takes an intense red colour, and lead sulphate is precipitated, which is filtered off after some hours.To the alcoholic solution is added about 20 times its volume of water, when almost the whole of the colouriiig matter is precipitated ; this is collected, washed, and dried at a low temperature. To purify the product, it is dissolved i n alcohol, and evaporated in a vacuum over sulphuric acid. The colouring matter of berries and flowers used to falsify wine can also be isola.ted by this method. Method of Detecting Artificial Coloration in Wine. By G. PAPASOGLI (L'Orosi, 14, 37--47).-1f a thin film of transparent, colourless gelatin is immersed in the sample of wine for 10 to 15 minutes, and dried by pressure between filter paper, it remains colourless if the wiue is genuine, but acquires a distinctive tint i f any artificial colouring matter is present.When the stained films are treated with sodium carbonate, stannous chloride, or copper acetate, they undergo further changes of colour by which the common dyes may be distinguished from each other. The presence of small quan- tities of coal-tar colours may be readily detected by this method, which, however, is less sensitive to colouring matters of vegetable origin. For the latter, the following method is proposed :-2 or 3 C.C. of a 10 per cent. solution of lead nitrate is added to 15 C.C. of the wine, the mixture filtered, and the precipitate on the filter covered with the solution of lead nitrate; when this has run through, it is treated on the filter with 6 to 8 C.C. of a saturated solution of borax.A turbid filtrate passes throngh, which yields a colourless solution on 1-efiltration if the wine is either pure or only contains extract of log- woDd or brazilwood, or very small quantities of extract of hollyhock (dlthea rosea) or of bilberry ( Vaccinium mil-tillus). An addition of 15 C.C. of the borax solution is also made to the wine filtered 08 from the lead nitrate ; the liquid, after separation of the precipitate, remains colourless i f the wine is pure, or only contains the colouring matters just mentioned. Logwood and brazilwood are specially tested for by agitating 10 to J. T.1564 ABSTRACTS OF CHEMICAL PAPERS. 15 C.C. of wine with dilute sulphuric acid (2 c.c.) and manganese dioxide (4 grams), filtering, and treating the straw-coloured filtrate with stannous chloride.If the above-mentioned dyes are present, the liquid becomes red. The presence of the colouring matter of hollyhock or bilberry is detected by comparing the colour of a mixture of 10 C.C. of the sample and 90 C.C. of a solution of sodium hydrogen sulphite with that of 10 C.C. of a pure wine of the same depth of colour as the sample and 90 C.C. of sulphite. The presence of the adulteration is indicated by n diminution in the intensity of the colour. F u l l tables are given for the discrimination of the colour..; absorbed by the gelatin, and of the colours produced in the boracic liquids i n cases of sophistication. Assay of Indigo.. By F. VOELLER (Zeit. a.ng. Chem., 1891, 110- Ill).-Processeg based on oxidation with potassium permanganate ; hydrochloric acid and chloride of limo ; sulphuric acid and potassium clichromate, &c., do not give satisfactory results, as commercial indigo usually contains other organic matters (oxalic acid has even been employed as an adulterant) ; besides it is a very difficult matter to properly notice the end-reaction when titrating. The same foreign matters also interfere with the accuracy of reduction processes, such as Pugh’s, with ferrous sulphat4e and sodium hydroxide, or Fritsche’s, with glucose, alkali, and alcohol, where the object is to reduce the indigo-blue to indigo-white, and to finally reoxidise this to the blue compound. Berzelius found that, besides indigo-blue and some mineral matter, the commercial product coztains three other sub- stances, which he called indigo-gluten, indigo-red, and indigo-brown. The first, which is soluble in dilute acids, bears some resemblance to vegetable case’in, and is precipitated from its solution by alcohol and tannin. The second, which is mostly met with in samples pre- pared by the lime process, is soluble in alkalis, whilst the third is soluble in hot alcohol. Berzelius’ process for the assay of commercial indigo is to first extract the sample with hydrochloric or acetic acid, then with alkali, and finally with hot alcohol and water, when a fairly pure indigo-blue will be obtained. The author has improved the process by estimating the nitrogen in the purified product by Kjel- dahl’s method, and calculating from this the percentage of pure indigo-blue, by multiplying by the factor 9-36, After verifying the accuracy of the process on a sample of sublimed indigo, he analyses the crude product as follows :-The washings with acid, soda, alcohol, and hot water are performed in a perforated platinum crucible, dosed with asbestos, and connected with a filter pump. The asbestos containing the indigo-blue is then boiled with sulphuric acid and a drop of mercury, and the ammonia. so produced estimated FIS usual. L. UE K. S. B. A. A.
