THE QUARTERLY JOURNAL OF TEE CHEMICAL SOCIETY. By R. HAINES,M.B. PROFESSOR OF MATERIA H‘TDICA IN THE GRANT MEDICAL COLLEGE BOMBAY. THISumbelliferous plant grows abundantly in Rajpootana and in various other parts of Central India. The fruit is short compressed laterally ;and in shape size and appearance very closely resembles that of Conirmt mnculuturn. It has a powerful and agreeable odour of thyme. The process of extracting its volatile oil is well known to the natives and is practised pretty extensively in the state of Judore and the neighbouring territories. The oil is used by the native doctors as a carminative under the name of Ajzua ke tel or Ajwa oil. This as sold in the Bombay bazaars is of a dark amber-yellow coloiir somewhat viscid and not pouring freely as if loaded with resin or fixed oil.It bas a pure odour of thyme. Redistilled with water it yielded after cohobating the water several times a little more than one-fourth of its bulk of a limpid bright yellow oil. The residue was a dark orange-yellow viscid oily liquid almost free from odour. This resid.ue was sparingly soluble in alcohol even when boiling and itself dissolved an appreciable quantity of alcohol. On evaporating the alcoholic solution the oil was obtained unchanged in its pro-perties. It did not appear to contain resin. It was more soluble in ether. Boiled with potash it formed a soluble soap. Under a heat gi*aclually increasing to near redness it was converted into volatile VOL. virI.--No. XXXII. U MR.R. HAINES ON liquid and gaseous products giving off the pungent odour of acrolein. A small residue of carbon was left in the retort. Warmed with solution of pernitrate of mercury it did not solidify or undergo any material change beyond becoming of a darker colour and somewhat more viscid. It consisted therefore essentially of a siccative fixed oil,-probably poppy oil,-with which the volatile oil had been adulterated. The rectified oil distilled by itself began to boil at 350' F. the boiling point slowly rose to 366O at which about one-third came over and then advanced more rapidly to 450'. A small dark-coloured residue was left in the retort. The product by repeated fractional distillation was separated into two portions one boiling at 353' the other at 440'-450'; the former amounting to about two-thirds the latter to one-third of the whole.The more volatile portion was colourless refracted light strongly and had a peculiar sweetish smoky odour reminding somewhat of caraway but entirely distinct from that of thyme. Digested over powdered chloride of calcium and re-distilled it retained the same boiling point. Re-distilled over hydrate of soda its boiling point was reduced to 347" at which it remained constant. Its specific gravity at 80' was 0.845. Burnt with oxide of copper the following results were obtained :-I. 6.69grains gave 6.43 water. 11. 8-62 , , 8-20 , and 28.51carbonic acid. 111. 7-59 , , 7.35 , , 24.92 , , Calculated.

Its odour was that of the original oil but more concentrated. When kept for several days it did not crystallive; but on throwing into it a minute fragment of the stemoptene previously deposited from the oil crys- tals began to form immediately and in a few hours it bad become almost wholly converted into nearly colourless crystals forming flattish THE VOLATILE OIL OF PTYCHOTIS AJWAN. tables of a rhomboidal shape surronnded by a dark yellow oily liquid. By pressure between folds of blotting paper the crystals were obtained dry and pure.They were then found to be identical with the crystals sold in the bazaar as Ajwa kapid or flowers of Ajwa.* They have a powerful odour of thyme and a hot and very pungent taste; are insoluble in water but freely soluble in alcohol ether and volatile oils. At 127"F. they melt to a colourless liquid which begins to boil at 439";but the temperature quickly rises to 447O at which the whole comes over. The distilled liquid is colourlese not so strongly refractive as the more volatile liquid and it may be kept for weeks in closed vessels in a fluid state until a fragment however minute of its crystal is thrown in when cry stallisation instantly begins in all directions throughout the liquid. The latter was neutral to test-paper.Its specific gravity at 78*was 0.939. Sulphuric acid combines with it without charring forming a colourless or pinkish crystalline mass soluble in water and yielding a soluble salt with baryta. Nitric acid aided by heat oxidises it rapidly and gives rise to the production of a gamboge-yellow sticky resin. A crystal thrown into nitro-muriatic acid causes the instant forma-tion of a dark green colour which passes after a few minutes into brown with the formation of a resin. It did not combine with hydrate of soda or with a strong solution of potassa. Heated with solid potassa it yieided no ammonia. It was analysed by combustion with oxide of copper.

I could not observe however the pro- perty which M.Lallenian d assigns to thymole,-of combining with caustic alkalies. The reaction with nitro-muriatic acid is also T believe new. Oil of Ajwa then combines the properties of the oils of cumin and thyme having the hydrocarbon of the one and the oxidised oil of the other thus :-C,,H, = Cyniole -Hydrocarbon of Ajwa oil ; C2,H,,0,= Thymole-Stearoptene of ditto ; and it thus presents an exception to the general relation of the coni-ponents of volatile oils the stearoptene being simply the hydrocarbon plus oxygen without the separation of any portion of the hydrogen.

MR. ALFRED NOBLE ON By ALFREDNOBLE ASSLSTANT IN THE ROYAL COLLEGE OF CHEMISTBY. WHILEconverting nitrobenzole into aniline by &I. A. Bechamp’s modification of Zinin’s process I observed a few facts which I beg permission to lay before the Chemical Society. M. Bhchamp’s process consists in reducing the nitrobenzole by a mixture of iron filings and acetic acid ; and his method is remarkable for the facility with which the conversion of the nitrobenzole is effected,-the former method as chemists will recollect being slow and extremely imperfect. The proportions recornmended by M. B6champ* are 2 parts of nitrobenzole 2 parts of acetic acid and 3 parts of iron filings. In an experiment in which the amount of iron was considerably increased above the proportions indicated I found that the result of the operation materially differed from what hi.Be‘champ had observed. The first portion of the distillate as in 11.B6champ’s process consisted essentially of aniline mixed * Ann. Ch. Phys. xlii. AZOBENZOLE AND BENZIDINE. with a small amount of nitrobenzole which had escaped decom-position ; whilst the last product,-about one-third of the whole -was a liquid of a deep red colour which solidified in the neck of the retort and in the condenser-tube into a beautifully crystalline com- pound. The results of several repetitions of this operation satisfied me that the largest quantity of this substance was obtained if the amount of iron employed was double that recommended by M. B6champ viz.3 parts of iron to 1of nitrobenzole and 1of acetic acid. This red crystalline substance was purified by washing first with HC1 (to separate any adhering aniline) then with water and after- wards dissolving in boiling alcohol when on cooling yellowish-red crystalline plates were deposited. These crystals were recrystallised once more from alcohol and dried in the water-bath at which tempe- rature they fused their composition was determined by a combus- tion with oxide of copper. 0.26 grm. of substance gave 0*755grm. of CO, and 0.134 grm. of HO. These numbers lead to the formula of azobenzole C,,H,N as may be seen from the following comparison of the theoretical and experi- mental numbers :-Theory. Equivalent. Percentage.

A portion of azobenzole obtained by the above method was con-verted into benzidine by Zinin’s well-known process viz. by treating an alcoholic solution of this substance with ammonia and sulphuretted hydrogen. An analysis of the platinum-salt of the base thus obtained furnished an additional proof of the identity of the substance obtained as described above with azobenzole. 0.268 grm. of platinum-salt gave 0.088 grm. of platinum = 32.88 per cent. of 1%.

The fact cd the reproduction of this body from benzidine was moreover established by a combustion which furnished the following numbers :-0,315grm. of substance gave 0.623grm. of CO, and 0.112 grm. of HO.

DH. MATTHlESSEN ON BARIUM. XIV.-A Few Notes OPZ Barium. By A. MATTHIESSEN, Ph.D. IN continuing my researches in Professor Bunsen’s laboratory on the electrolytical separation of the metals of the alkalies and alkaline earths it has not been possible for rnc to obtain barium in ti regulus MR. ADJE ON HYDRO-ELECTRIC CURRENTS. after the same manner in which strontium and calcium have been isolated but I have invariably separated it in the form of a finely- divided powder. The reason of this appears to be that at the tem- perature at which the chloride fuses the metal attacks the pipe-stem and decomposes small quantities of alumina and silica at the same time forming baryta which prevents the powder melting together. As the iodides bromides and fluorides are either infusible or only fuse at a temperature where the same circumstances hinder the powder from melting together it does not seem probable that barium can be obtained in a regulus electrolytically like calcium or strontium.The barium powder bas a yellow colour like strontium decomposes water at ordinary temperatures and oxidises quickly when exposed to the atmosphere. If at the negative pole a platinum wire be used in lieu of the iron one and the electrolysis be conducted otherwise in the same manner as in the separation of strontium an alloy of platinum with barium will be formed. This alloy like those of calcium and strontium possesses a yellow colour is very brittle and decomposes water slowly at ordinary temperatures leaving the pla- tinum in a finely-divided state.On the Hydro-electric Currents generated by Couples formed of Single Metals. By Richard Adie. THE mode of experimenting mas as follows :-Two square pieces of the same metal having an area varying from one-fourth to one-tenth of a square inch (the preference being ultimately given to small plates) were connected with a delicate galvanometer by means of narrow strips partly cut from one of their edges and turned vertically upvards. They were then cemented down to a flat plate so as to expose only one of their surfaces and au6cient water poured on to cover them. An acid liquid was then poured by means of a pipette over one of the plates and its effect on the galvanometer noted. The general results of the experiments are given in the following table in which the word positioe or nqquctice denotes the state of the riictnl on which the acid was poured :- MR.ADIE ON HYDRO-ELECTRIC CUHRENTS.

NOTICES OF PAPERS CONTAINED IN OTHER JOURNALS. BYHENRY B.A. F.C.S. WATTS On Coumaramine a new Organic Base derived from Nitrocoumarine.* By A. Frapolli and L. Chiozza. R L E I B T RE U in his research on coumarine,? mentions some experi- irientv made for the purpose of decomposing nitrocoumarine. The product which he obtained by treating an alcoholic solution of nitro-coumarine with sulphide of ammonium was uncrystallisable dissolved in ammonia and gave with lead and silver salts precipitates con-tainiug sulphur. The action of other ordinary reducing agents likewise fails to yield any simple and definite result. Hydrogen in the nascent state as evolved from a solution of nitrocoumarine in potash has no action on that body; neither is any reducing action exerted by hypophosphite of potash or ammonia.The only process by which the authors have been able to effect the reduction of nitro-coumarine consists in the employment of ferrous acetate,-a body whose advantages as a reducing agent have been already pointed out by B6champ.f When nitrocoumarine is introduced into a mixture of acetic acid and iron filings and the liquid heated in the water-bath action soon takes place ; ferric oxide separates out in considerable quantity ; and as the mixture cools yellow needles are deposited on the sides of the vessel. To render the action complete the substances must be leftin contact for twenty-four hours. The precipitated ferric oxide is then fil- tered from the solution of ferrous acetate the solution concentrated by evaporation repeatedly filtered hot during the evaporation to separate the ferric oxide which is continually forming and then left to cool.It then deposits yellow crystalline needles of an organic base which the authors designate by the name Cotmaranuhe. Alcohol extracts from the precipitate an additional quantity of * Ann. Ch. Pharm. xcv. 252. 1. Ihid. lix. 177. 1 Ibid. scii. 401.

This second aqueous solution is to be treated like the first. During the concentration and filtration of the aqueous solutions part of the coumaramine appears to be decomposed and the crystals obtained from such a solution are always contaminated with an amorphous brown precipitate.The crystals which first separated werc purified by repeated crys- tallisation from water ; they then formed beautiful prismatic needles of reddish-yellow colour. When a few grammes of substance are used crystals 6 or 8 centimetrev long may be readily obtained. These crystals dissolve but very sparingly in cold water but appear to be more easily soluble in a saturated solution of ferrous acetate. Boiling water dissolves coumaramine with facility ; so likewise does boiling alcohol. An alcoholic solution saturated at a boiling heat solidifies on cooling. Coumaramine is nearly insoluble in ether. It melts between 168' and 170' C. and when carefully raised to a higher temperature gives off yellow vapours which condense to pale yellow laminae.When cournaramine is quickly heated in a tube over a spirit- lamp it tarns brown and distils over in the form of a heavy oil which condenses to yellow crystals contaminated with a small quantity of an oil smelling like aniline. The analysis of coumaramine yielded the following results which agree with the formula CI8H7NO,. Found. --l Calciilated.

On adding ammonia to an aqueous solution of hydrochlorate of couniara-mine the liquid solidifies to a mass of crystals of coumaramine.Aboiling solutionof caustic potash rapidly decomposes coumaramine. On neutralising the liquid with an acid brown flakes are deposited. On adding a solution of bichloride of platinum to a solution of hydrochlorate of coumaramine a yellow crystalline precipkate is ob- tained insoluble in water and yielding by analysis 26.7 per cent. platinurn.

IF a mixture be prepared of 2 parts of caustic potash and 1 part of lime moistened with water so as to form a thick paste and 1 part of mononitronaphthalin be then added to the mixture by degrees the mass immediately acquires a reddish-yellow colour which is due to the formation of a peculiar acid.The mass is heated for about six hours to a temperature which must not pass 100"C. with the addition from time to time of a few drops of water to replace that which is driven off. At the end of this time the reaction is complete. The mass washed by decantation until the water is no longer alkaline is treated with an acid which separates the lime. The product thus obtained contains two matters one yellow and crystallisable the other brown and uncrystallisable. It is then distilled either by steam or by the open fire ; the latter process is the more rapid but furnishes a pro- duct of less purity and in adopting it the operation must be stopped when red fumes begin to appear.The substance distilled forms crystals almost immediately. This body crystallised from boiling alcohol furnishes long crystals of a straw-yellow colour ; they are insipid and of a weak aromatic odour. The substance fuses at 48' C. boils at 290' C. and passes over in great quantity at 300' to 320' C. leaving a slight carbonaceons residue. It is very soluble in alcohol ether and the hydrocarbons. Boiling water dissolves a small quantity of it and allows it to crys- tallise on cooling. A very concentrated solution of potash acts upon it furnishing a yellow acid. When distilled with a mixture of potash and lime it furnishes a yellow odoriferous oil and long needles which communicate a fine violet-blue colour to sulphuric acid.The oily matter dissolves readily in water ; a few drops of perchloride of iron added to the solution give it an intense blue colour and blue flakes are soon precipitated ;these are changed to red by alkalies. Sulphuric acid dissolves it with red colour. Sulphide of ammonium gives a new a1 kaloid. Phtlzulidine Ci6H,N.-This compound is produced by the action of sulphide of ammonium upon nitrophthaline. The action is greatly assisted by keeping the solution at a temperature of about 50' C. on the watermbath for a few hours. After the alcohol has been driven off the residue is exhausted by dilute muriatic acid and filtered after cooling. Potash gives rise at first to a white precipitate which is redissolved in the excess of acid with a fine blue colonr ; a greater quantity of potash separates the alkaloid in the form of flesh-coloured flakes which soon change to red as they become aggregated.When * Compt. rend. xli. 493. 304 DUYART ON SOME DERIVATIVES OF NAPHTHALIN. washed and then crystallised by fusion it is of the red colour of realgar ; its odour resembles that of naphtbalidine and its taste is sharp and disagreeable. It melts at 22' C. At the moment of solidification the thermo- nieter rises to 34O.5 C. when it remains stationary. It begins to boil at about 255' C. but the temperature then rises rapidly and the substance becomes partially altered leaving a carbonaceous residue. It has no action upon reddened litmus but its vapours immediately turn the litmus blue.It dissolves in ether and alcohol and also in considerable quantity in cold water from which it is deposited in long needles. Its aqueous solution precipitates the salts of suboxide and protoxide of mercury. It reduces nitrate of silver. A few drops of sesquichloride of iron give a fine blue colour this reaction which is very delicate is likewise exhibited by morphine and salicylic acid. It furnishes well-crystal- lised salts with all the acids. Bichloride of platinum reduces it when the solution of the hydrochlorate is diluted furnishing blue flakes which become black in drying. If the solution of the hydrochlorate is very concentrated this reagent furnishes fine yellow crystals which undergo a change in drying. The author was therefore unable to determine the equivalent by the analysis of the platinum-salt.ATz'it*ophthaZinicAcid C32Hl,NOl,.-Obtained in the preparation of the nitrophtbaline by a secondary reaction of the potash upon that body. It is then contaminated by a foreign substance which is difficult to remove. It niap be more advantageously prepared by treating pure nitrophthaline with a very concentrated solution of potash. Its formation is exceedingly slow. The potash-salt obtained is treated with water filtered and decom- posed by muriatic acid. The acid is crystallised from a mixture of 1 part of water and 2 of alcohol of spec. grav. 0.848;it yields on cooling small golden-yellow crystals grouped in stars. The acid is inodorous ; its taste is scarcely perceptible at first but afterwards becomes sharp.When heated in a tube it fuses and leaves a carbonaceous residue. The potash-salt is obtained by leaving the alcoholic solution to stand ; it is deposited in small reddish- yellow marrimellated crystals. It is verysoluble in water to which it gives a strong yellow colonr. With nitrate of silver it forms a precipitate of a fine red colonr ;with acetate of lead an orange-yellow precipitate; and a greenish-yellow precipitate with salts of copper. Most of its metallic salts explode on the application of heat. DUSART ON A NEW MODE OF PRODUCING PROPYLEKE. $05 Note on R New Mode of producing Propylene.* By L. Dusart. IF a mixture of an alkaline acetate and oxalate be distilled in such a manner as to place the acetone formed in contact when in the nascent state with the oxide of carbon produced by the decomposition of the oxalate deoxidation of the acetone takes place with formation of a carbonate and a gas passes which is absorbable by bromine and which is nothing but propylene.The reaction may be represented by the following equation :-C6H602 + 2CO = 2C0 + C,H6. Nevertheless we by no means obtain the quantity of propylene indi- cated by theory. The decomposition of the two salts is not simulta- neous and the oily matter observed in the preparation of acetone is always produced. The process adopted is as follows :-Equivalent portions of acetate of lime and oxalate of potash are taken; the oxalate is dissolved in water and the acetate of lime added to it so as to produce oxalate of lime and acetate of potash.The liquid is evaporated and kept in continual motion to obtain an intimate mixture. When dried as much as possible the mass is put into a retort. which is heated over a mode- rate fire and the quantity of propylene appears to be increased if the temperature be gradually and slowly raised. The gas passes first into a flask filled with carded cotton then into a flask containing sulphuric acid to absorb the oily matter ; and it is afterwards condensed in bro- mine after being washed in water. A kilogramme of acetate of lime furnishes abqut 60 grms. of crude propylene. The liquid obtained is mashed with potash and distilled directly ; it is then agitated again with an alkaline solution which saturates the hydrobromic acid formed during the distillation.Jt is dried over chloride of calcium and distilled with a thermometer inserted. Bromide of propylene forms about two-thirds of the product. It possesses the odour and the boiling-point (14<5'C.) of the propylene obtained from amylic alcohol. The compound C,H,Br obtained by the action of an alcoholic solu- tion of potash upon the preceding product when heated in a tube with sulphocyanide of potassium furnished the essential oil of mustard which has recently been produced by M. Berthelot with iodo-propy- lene obtained from glycerine. It is therefore possible by a simple deoxidation of acetone to ascend from the acetic to the propylieseries and to reproduce the alcohol if instead of collecting the hydrocarbon in bromine we cause it to be absorbed by sulyhuric acid and distil it with water according to the ingenious process of this chemist.* Compt. rend. xli. 495. VOL. VIIL.-NO. XXXII. X 306 CASSELMANN ON TARTRATE OF LIMEAND TARTARIC ACID. On Tartrate of Lime and a Reaction of Tartaric Acid." By A. Casselmsnn. THEauthor when occupied in the examination of Alexandrian senna found that the aqueous extract deposited the lime-salt of an organic acid on evaporatitm. This salt possessed a remarkable property ;when gradually heated after the addition of ammonia and nitrate of silver it covered the sides of the test-glass with a metallic speculum of silver in such a manner that the reaetion may be compared with the reduc- tion of nitrate of silver by aldehyde-ammonia.Even a very small quantity of the lime-salt was sufficient to reduce the nitrate of silver in the manner above mentioned but only when the nitrate was added in small fragments instead of in solution. If it were added in solu- tion the reduced silver was deposited in the form of a grey powder. When the hot solution of the lime-salt was mixed with neutral acetate of lead an abundant white precipitate was obtained which however always contained traces of the lime-salt unless the fluid were rapidly filtered whilst boiling. This precipitate was decomposed by sulphuretted hydrogen ;the fluid containing the pure acid was eva- porated and the acid was obtained as a syrupy sharply acid fluid which exhibited no trace of crystallisation even after standing for several weeks.The lead-salt of the acid was found to have the composition of tar-trate of lead. 8C 48-0 13.5 13.5 4H 4.0 1.1 1.5 10 0 80.0 22.6 22.7 2 YbO 223.2 6.2-8 62.3 355-2 100.0 100.0 Comparative experiments with artificially prepared tartrate of lime presented the same behavioiir. The remarkable fact that tartaric acid in one of its least soluble compounds possesses the property of instantaneously reducing nitrate of silver might be made use of in analysis for the detection of minute traces of this acid. Racemic acid however gives the same reaction and also produces it instanta- neously only when the nitrate of silver is added in the solid state. Tartrate of lime occurs in considerable quantity in senna-leaves ; but from its sparing solubility is not obtained from them without difficulty.The author has made experiments upon the solubility of tartrate of lime and found that this salt requires for its solution 350 parts of boiling and 1210 parts of cold water. The author also boiled tartrate of silver with ammonia to ascertain whether as stated by Werther a new ammoniacal salt is thus pro-duced. He wasixnable to find anything of the kind. * Arch.

DURINGan investigation of the ashes of various kinds of gums, Lo went h a1 prepared arabin by the process employed by Sch m id for the purification of tragacanth &c. This process consists in dissolving gum-arabic in cold water so as to form as thick a mucilage as possible filtering and adding hydrochloric acid till a strong acid reaction is produced when the arabin is precipitated by means of alcohol ; and these solutions and precipitations were repeated several times.The arabin thus prepared in the form of a white amorphous mass readily dissolves in water while still moist forming a mucilage ; the aqueous solution is not precipitated by alcohol unless after the addition of hydrochloric acid or solution of chloride of sodium when precipitation takes place immediately. The aqueous solution of pure arabin exhibits an acid reaction. When dried in the air arabin becomes glassy and transparent and gradually loses its solubility in water ;when dried at 100" C.it is no longer soluble in water but only swells up in a gelatinous form in that fluid. The composition of arabin dried at 100' C. agrees with the formula C,,H,lOll; at a higher temperature it appear8 to give off no more water until it begins to decompose. Arabine dried at 100' C. and having an acid reaction when mixed with lime-water until an alkaline reaction was produced soon regained its acid reaction. From the fluid obtained by the action of lime-water upon arabin alcohol sepa- rates a lime-compound which readily dissolves in water forming a mucilage and when dried at 100"C. has the formula Ca0,6Cl,H,,0,,. From the fluid obtained by boiling arabin with water and an excess of hydrated lime alcohol separates another linie-compound which also dissolves readily in water this when dried at 100' C.consists of Ca0,2Cl,Hl,0,,. By treating arabin with baryta-water (not in excess) and precipitating the liquid with alcohol a baryta-compound is obtained which when dried at 100' C. contains 114 to 11.2 per cent. of baryta. An excess of baryta-water furnished a compound containing 17.5 to 17.8 per cent. of baryta the cornposition of which when dried at 100' C. approached very closely to the formula Ba0,2C12H loOlo. A potash-compound precipitated by alcohol from a solution of arabin in potash had the constitution K0,3C12H,,0,0 when dried at 100" C. Basic acetate of lead precipitates a lead com- pound from the aqueous solution of arabin; this becomes of a slight yellowish colour when dried at 100' C.and of a strong brown at 160°to 180' C. Portions prepared at different times and dried at looo C. contained 27.0,305 to 30.8,and 30.5 to 30.7 per cent. of oxide of lead the composition of the latter preparations approaches the formula 2Pb0 3C12H10010. * J. pr.

BUSSYstates that the product of this operation is stearone,-a body which may be regarded as anhydrous stearic acid from which a num- ber of equivalents of carbonic acid have been separated equal to the number of equivalents of base which it was capable of saturating. Rowney however has recently asserted that the solid fusible body formed is constituted according to the formula C,,H%O.He calls it stearene. From the results of the previous investigations of Heintz upon the products of the distillation of hydrated stearic acid we may draw the conclusion that Bussy's view of the products of decomposition of stearate of lime is the correct one and that it only requires correction in so far as the stearone formed is itself partially decomposed by the heat required for the decomposition. The examination of the products of distillation of stearate of lime has shown that this conclusion is perfectly correct. The author found in this operation that the products were partly gaseous and partly solid. The former consist of hydrocarbons of the formula C,H, and of light carburetted hydrogen which is produced from the former by separation of carbon ; the solid products consist of stearone (C3,H&) and other ketones which are produced along with the hydrocarbons by the decomposition of the stearone.The decomposition may be expressed by the equations,- The author obtained pure stearone by repeated extraction of the above-mentimed products of distillation with alcohol and recrystal- lising the undissolved portion from its solution in boiling ether. It possessed all the properties gf that produced by the. distillation of hydrated stearic acid but its melting-point was a little higher namely 87O.5 C. ; evidently in consequence of its greater purity. To determine the atomic weight of stearone the author prepared a product of substitution by means of bromine whizh he found to be -1 constituted according to the forlnulir C,5 { ::*10.From the analysis of the portion of the crude stearone which was soluble in alcohol it appeared to contain the same number of equivalents of hydrogen and carbon but a larger amount of oxygen showing that it contained (perhaps together with stearone) other ketones with a smaller amount of carbon and hydrogen. * Wieu Ak-ad.
