PROCEEDINGS OF THR CHEMICAL SOCIETY. EDITED BY THE XECRETARIES. Vol. 18. No. 250. March 26th, 1902. Annual General Meeting, Professor EMERSON REYNOLDS,Sc.D., V.P.R.S., President, in the Chair. Dr. HENRY were appointed Scrutators, and a ballotand Mr. RAMAGE was opened for the election of Officers and Council for the ensuing year. The PRESIDENT,in beginning his address, said that he had the agree- able duty of congratulating the Fellows on the continued and ever increasing prosperity of the Society. The numerical strength of the Society was 2335 on March 28th, 1901. Since that date 163 Fellows had been elected, and 3 had been reinstated by the Council, making a gross total of 2501. Of these, 32 had withdrawn, 25 had been removed for non-payment of two annual subscriptions, and 21 had died.The actual number of Fellows to date was therefore 2423, the highest number yet reached, and the number of Foreign Members was 32. The names of those removed for non-payment of subscriptions were :-E. W. Allsom, W. D. Bohm, C. F. Branson, T. H. Coleman, E. D. Ewen, F. G. Fuller, C. H. Field, W. G. Fraser, A. T. Gailleton, W. H. Grieve, T. C. Hepworth, A. F. Hogg, J. Harger, W. Ince, R. 8.Ladell, R. D. Littlefield, D. C. Mackenzie, A. Mackay, F. L. Overend, M. Pearson, 8.Smith, A. H. Turton, C. W. Vincent, W. a.Walker, A. Walton. The following have withdrawn :-J. M. Arnot, W. H. Barr, F. Belton, H. D. Berridge, M. Cochran, W. Collingridge, J. Craig, HaL. Dampier, M. J. R. Dunstsn, G.Evam, 78 H. P. FitzGerald, P. H. Grant, W, H. Greene, H. W. Gough, A. B. Griffiths, J. B. Guyer, H. M. Hastings, E. S. Hayward, A. H. Mac-donald, C. J. S. Makin, J. Maudsley, J. McLeod, H. C. Myers, G. A. Parkes, L. G. Patterson, J. C. Quinn, A. Schloesser, C. Thompson, E. A. Wates, J. I. Whimster, B. W. Winder, S. Wood. The following have died :-F. J. Beale, J. H. Beckett, Henry Bird, Sir J. H. Gilbert, F.R.S., A. Hartridge, Alexander Hay, Lawrence Hislop, David Johnson, N. Leonard, H. G. Madnn, Dr. Ira Moora, Dr. G. Harris Morris, John Paul, W. Shapleigh, Louis Siebold, Prof. Maxwell Simpson, F.R.S., 'W. T. N. Spivey, W. Terrill, John Thomson, J. L. W. Thudichurn, G. F. Wilson, F.R.S. The most important test of the prosperity of the Society was, how- ever, to be found in the record of its work.In this respect also he had a favourable report to make. Since the last anniversary, 181 com-munications had been made to the Society. Abstracts of all these had appeared in the Proceedings, whilst 139 had already been published in the Trainsc6ctions. He ventured to think that the quality, generally, of the work presented was as high as in any previous year, and clearly indicated the continued enthusiasm and activity of the Fellows. The Transactions for 1901 contained 146 memoirs, occupying 1411 pages; and the volume of the preceding year 127 memoirs occupying 1334 pages. The volumes for 1901 contain 3754 abstracts of papers, published mainly in Continental journals, occupying 1496 pages, arranged as follows : PARTI.Pages. No. of Abstracts. Organic Chemistry.. ............................... 784 1530 PART11. General and Physical Chemistry ............... 403 Inorganic Chemistry .............................. 376 Mineralogical Chemistry ...................... 169 Physiological Chemistry ........................ 363 Chemistry of Vegetable Physiology and Agri- culture ........................................... 306 Ant-tlytical Chemistry .............................. -607 712 2224 -Total in Parts I. and 11. .................... 1496 3574 The volume for 1901 contained n Memorial Lecture giving an account of the life-work of Rarnmelsberg. A set of the Memorial Lecture8 79 which had appeared up to the end of 1900 was issued in September last in a separate form.The use of the Library by the Fellows continued to show their ap- preciation of it. Eight hundred and eighty books had been borrowed, as against 810 during the corresponding period of last year. A large number of these were Journals issued by post to Fellows resident in the country, and the Library Committee invited special attention to this development of the Society’s usefulness. The additions to the Library comprised 153 books, 441 volumes of periodicals, and 33 pamphlets as against 95 books, 327 volumes of periodicals, and 30 pamphlets during the corresponding period of last year. It was desirable that the Society should have in the Library a copy of, at least, every work printed in English on chemical subjects to the end of the 18th century, and he would invite the co-operation of the Fellows in making the Library complete in this direction.In the preparation of the new Library catalogue, the printing of which had been decided upon, advantage was taken of the opportunity to construct anew and convenient Card Catalogue, which, it was believed, would materially assist readers in making use of the Library. It was his privilege to offer, on behalf of theSociety, its warm con- gratulations to Dr. Schunck, to Mr. Lloyd Bullock, and toDr. Francis, who this year have reached their sixtieth anniversary of admission to the Fellowship of the Society. He had pleasure to add that Mr. Buckton, F.R.S., Mr.F. Claudet, and Mr. Darby have reached their jubilee, and to them he would also convey its sincere congratulations. Last year their illustrious senior Foreign Fellow, M. Berthelot, celebrated the fiftieth anniversary of his first scientific publication, and all countries united in expressing their admiration and respect for the veteran chemist. On behalf of the Society, he, with Dr. Gladstone and Professor Ramsay, presented a congratulatory address to M. Berthelot at the imposing function which was held in the Sorbonne on November 24th, 1901. This address had already been printed in the Proceedings. During the year, the Society had joined in the celebration of the 450th anniversary of Glasgow University, and in the jubilee of Owens College, Manchester.Considering the large number of Fellows now in the Society, the mortality is small ;nevertheless, this year they had to regret the loss of 21 Fellows. This melancholy list includes the name of Sir Henry Gilbert, Past President of this Society, and one ever devoted to its welfare. His immense work, carried out with Sir John Lawes, laid the scientific foundation of British Agriculture and serves a8 the model on which all future researches must proceed. The Society was fully represented on the sad occasion when Sir Henry Gilbert wa8 interred, 80 and its representatives laid a wreath on his grave, while later on the Council passed a vote of condolence with his mourning relatives. In a short time, he hoped, a full obituary notice would be published by one far more competent to undertake it than he.Dr. Maxwell Simpson is another of those passed away from amongst us, fidl of years, leaving memories of good work well done, especially in synthetic chemistry, and of him and of the other Fellows whose life-work has closed records will also be shortly published. Considerable discussion had taken place within the Society on the question of altering the day and hour of the Ordinary Meetings, which was raised in the address of his predecessor, Dr. Thorpe, last year. They had had two Extraordinary Meetings on this subject, and the outcome was the experiment now in operation, of trying alternate evening and afternoon Meetings until the end of the present session.Until that experiment had been fairly made, the best course, obviously, was to suspend judgment on the question. Grants amounting to 2250 had been made from the Research Fund in aid of chemical investigations. The remainder of the address dealt with certain aspects of the periodic law as modified by recent discovery. Dr. GLADSTONE,F.R.S., proposed a vote of thanks to the President, coupled with the request that he would allow his address to be printed in the Transactions. Dr. THORPE, C.B., F.R.S.,seconded the motion, which was carried by acclamation. The PRESIDENThaving returned thanks, Prof. TILDEN,F.R.S.,the Treasurer, in giving an account of the Balance Sheet which he laid before the Society, duly audited, said :-The receipts had been :-By admission fees and subscriptions, $4533 ; by sale of Journal and advertisements, $835 11s.2d. ;and by dividends on invested capital, $476 12s. 6d. The total receipts from all sources amounted to &5884 1s. 8d. The expenses had been: -On account of the Journal, 23233 0s. 2d.; on account of the Proceedings, &20 Is. 5d. ; on account of the Library Catalogue, $42 14s. 4d.; on account of the Library, S429 15s. 5d.; House expenses, &239 19s. Id.; the total expenditure being 2,4913 10s. 6d. The TREASURER, in concluding, proposed a vote of thanks to the auditors, which was acknowledged by Mr. CHAPMAN. Prof, H. B. DIXON,F.R.S., proposed a vote of thanks to the Treasurer, Secretaries, and Council. Dr. HEWITTseconded the motion, which was unanimously adopted.Prof. MELDOLA,F.R.S., responded. 81 The Scrutators having presented their report to the President, he declared that the following had been duly elected :-President : J.

Extra Meeting.Professor EMERSONREYNOLDS, Sc.D., V.P.R.S., President, in the Chair. This meeting was held in the Theatre of the Royal Institution, by kind permission of the Managers. Professor J. H. VAN'T HOFF,F.R.S., delivered the Raoult Memorial Lecture. Franqois Marie Raoult was born on May loth, 1830, at Fournes, in the Department of Nord. When he went to Paris to pursue his studies he had neither fortune nor patronage to assist him, so had to struggle to find means to keep himself. His first paper, published in 1853, contained observations on the transport of electrolytes by the galvanic current and on electrical endosmosis. In 1853 he was 82 appointed ‘I Aspirant repetiteur ” in the Rheims LycBe, in 1855 “ Rdgent de Physique” in the college at St.Die, after which he was again at Rheims, and in 1860 at Bar-le-Duc, employing his spare time in working for his degree of Licenci6 2s-Sciences physiques. In 1862, he proceeded to Sens, where, amidst adverse material surroundings, he prepared his thesis on Electromotive Force, for which in 1863 he obtained in Paris the degree of Doctew e‘s-Sciences physiques. The work of Raoult may be divided into three distinct parts : the physical, the chemical, and the physico-chemical. His career as a physicist begins with the thesis above referred to, by which he was marked out as an accurate and independent investigator already in advance of his time by the conclusions he based on a careful examina- tion of facts. In the first part of this research he measured and com- pared in the cells of the Daniel1 type the amount of heat due to the chemical action with that corresponding to the electrical work produced, and showed that they were by no means identical.The second part was devoted to the decompositions in the voltameter by the galvanic current, the thermal phenomena being especially studied. It was whilst carrying out his electro- and thermo-chemical investigations that Raoult entered the Facult6 des Sciences de Grenoble in 1867 as “charge du cours de Chimie,” being promoted in 1870 to the Chair of Chemistry, which he occupied until his death last year. From this time forward a change is visible in the direction of Raoult’s work, which now became of a more purely chemical kind, the problems still being looked at from the physical point of view.These problems included the examination of the gas from a (‘fontaine ardente,” which he showed to be merely methane, the proof of presence of copper and zinc as normal constituents of the human liver, the inverting action of light on sugar, He showed that the presence of carbon dioxide in air diminished the production of carbon dioxide in the lungs, but that this effect was counteracted by the increased pulmonary action. His discovery of a basic calcium car- bonate, CaCO,,CaO, which acts like plaster of Paris on the addition of water, formed the subject of his last purely chemical paper. After this, he definitely enters upon that line of research which he has made peculiarly his own, and in which he persevered until his death.His first paper on freezing points was published in 1878 and was of n purely empirical nature, pointing out the proportionality existing between the lowering of the freezing point and that of vapour pressure (or raising of boiling point). Probably owing to the difficulty of determining the strength of alcoholic liquors by means of their vapour pressures or boiling points, he tried their freezing points. How this was related to practical applications is shown by the table appended to the paper, the liquids beginning with cider and ending with Marsala, the freezing points varying from -2’ to -10*1’, and corresponding fairly with the proportion of alcohol.From solutions of ethyl alcohol he passed to those of other alcohols, and thence to other organic compounds, giving his well known table relating to twenty-nine substances. His conclusion was that the prsduct of the depression of freezing point of a solution containing 1 gram of sub-stance in 100 grams of water multiplied by the molecular weight of the dissolved substance is a constant. Two further papers in 1882 extended the freezing point law to solvents other than water, and he showed that each solvent has its own molecular constant which, pro- bably by the formation of double molecules of the dissolved substance, may be reduced to half the normal value. This constant is propor-tional to the molecular weight of the solvent (MI)and is on an K average -=0.62.From organic compounds he passed to the more difficult cases of salt solutions, beginning with those of acids and bases and finding that strong monobasic acids like hydrochloric acid and strong mono-acid bases like potassium hydroxide have a mole-cular depression of 37 whilst the weaker ones, like organic com-pounds, have only 18.5. He summed up his results thus : “These facts prove that, in opposition to what I had admitted up till now, the general law does not apply to dissolved salts; on the contrary they tend to indicate that it is applicable to the constituent radicles of the salts, almost as if these radicles were simply mixed in the solutions.’’ The early work of Raoult on voltaic cells was neglected, as it was much before its time, but his work on cryomopy appeared just in the nick of time and was soon warmly received everywhere.In 1892 he again took up his study of freezing points which had been interrupted in 1884, but now from the point of view of the new theory of solutions, and showed that the molecular depressions of potassium chloride and sugar, as well as of sodium chloride and alcohol, were in accordance with the hypothesis of Arrhenius. In his summary of work in this direction, Raoult admitted all the conclusions of the theory of solutions, but as a thoroughly experimental investigator he objected to build upon that large but hypothetical generalisation known as the extended Law of Avogadro. The relations existing between lowering of freezing point and of vapour pressure led Raoult to his tonometric work.He found (as Wullner had already proved in some cases) that the ratio existing between the lowering of the pressure (f-f),and the pressure itself (f), namely, f-y,the so-called relative lowering of pressure mas inde--f pendent of the temperature, His next step was to determine the 84 values of the moleculw relative lowering. He thus formulated what he found : “ One molecule of a non-volatile substance (salts excepted) dissolving in 100 molecules of any volatile liquid, diminishes the vapour pressure of that liquid by an almost constant fraction of its value, which is abGut 1.05 per cent.” This conclusion at once brought him into connection with the theory of solutions, and Raoult himself says of it, in 1887, that “the agreement between experiment and theory is thus in all respects as complete as one can desire in such matters.” In 1893, along with Recoura, he gave his most general and exact expression of the results of his vapour pressure obser-vations. Raoult’s constitution seems to have been a vigorous one, the only indication to the contrary being his resignation, in 1892, of an additional professorship which he had held.He ought to have re- tired in April, 1900, on account of his having reached the age limit for the tenure of his chair, but by special decision of the Trustees he remained in office ‘L hors cadre,” a very high honour, and a proof of his unbroken vigour at that time. In his last year, in two comprehensive papers, he summed up his views on Tonometry and on Cryoscopy ; it was just in time, for, with practically no premonitory symptoms, he died on April Ist, 1901.His character as a man may be read in his papers, in which he showed activity, patience, tenacity in pursuing an aim, as much eye for detail as for the vaster horizon, absolute independence of mind, criticising or admitting without bias views of others as well as his own, and testing both with the same calm conviction that the last word must rest with experiment. Prof. ODLINBin proposing a vote of thanks to Prof. ran’t Hoff, said that he mould not add a word to the appreciative, unaeected, and simple account of the work of Raoult. It was so lucid and com- plete that coming from any one it would have been of great interest, but in this case, coming from Prof.van’t Hoff, it gave all the greater pleasure. Prof. van’t Hoff’s work in inorganic chemistry had exercised a very great influence on modern chemical doctrine for a quarter of a century ;his work had excited a high degree of interest amongst English chemists, and to-night he had supplemented their acquaintance with his work by giving them the opportunity of making acquaintance with himself. The early work of Prof. van’t Hoff did not, and very properly so, win its way without some opposition, which in certain continental schools was unduly harsh. As with his theory of the chemical atom in space, so is it with the doctrine of osmotic pressure and the philosophy of solution.He could assure Prof, van’t Hoff that in no country had these been received with greater favour than in this, in spite of opposition more vivacious than weighty. They were accepted if not as 85 the final truth, if the truth a.t all, at any rate as running on all fours with the truth. The vote of thanks was seconded by Prof. DEWAB,and supported by Sir WILLIAMHUWINS,President of the Royal Society. Thursday, April 17th, 1902. Professor TILDEN,D.Sc., F.R.S., Treasurer, in the Chair. Messrs. Davis, DorQe, Aders Plimmer, Allworthy, and Bedwell were formally admitted Fellows of the Society. Certificates were read for the first time in favour of Messrs : Clough, William Thomas, 3, Watford Villas, Battersea Park, S.W.Davis, Henry Wilson, 18, Crescent Road, Kingston Hill, Surrey.

RQy. Some account has already been given (Proc., 1901, 17, 96) of the investigation which is here more fully and accurately described.Mercurous nitrite partly decomposes in dissolving in water, giving metallic mercury and a solution of both mercuric and mercurous nitrites (Tram., 1897, 71, 337). Adding to this solution just enough sodium chloride and filtering, there is left a solution of mercuric sodium nitrite, which gives, with excess of ammonia, a white precipitate of a new salt, 2NHg2N0,,H20,dimercurammonium nitrite. On dissolving it in hydrochloric acid and evaporating, there is left a new mercuric ammonium chloride, 2HgC12,NH,Cl, a white, crystalline, volatile, and fusible salt. The correspunding bromide can be obtained in a similar way, as well as by evaporating a hydrobromic acid solution of the single bromides in the right proportions; it is largely decom- posed by water into its component salts.With potassium hydroxide, not in excess, these double salts give dimercurammonium chloride 86 and bromide, 2NHg,Cl,HgCi,, and 2NHg,Br,HgBr,, the former not quite pure. With excess of potassium hydroxide, they yield the half- hydrated dimercurammonium chloride and bromide, 2NHg,C1 ,H20and 2NHg2Br,H,O, the former already described by Andr0. When either dimercurammonium chloride or bromide is dissolved in hydrobromic acid, the above-formulated mercuric ammonium bromide is obtained on evaporation ; when dimercurammonium bromide is dissolved in hydrochloric acid, a mercuric ammonium chlorobromide, 2HgCl,,NH4Br, is left on evaporation. From this chlorobrornide, potassium hydroxide reproduces quantitatively dimercurammonium bromide, a fact which led the author at first to regard the chloro- bromide as dimercurammonium bromide in union with 4 molecules of hydrochloric acid, and the corresponding double chloride and double bromide as NHg2C1,4HCI,and NHg2Br,4HBr,respectively, The author considers that the chemical composition of dimercur-ammonium nitrite and its derivatives gives much support to the Ram- melsberg-Pesci theory of the dimercurammonium constitution of all ammoniated mercury salts.“57. Preparation and properties of 4-isopropyldihydroresorcin. A correction.” By A. W. Crossley. The nomenclature adopted in the preliminary notice of this work (Proc., 1901, 17, 172) has been changed. The substance there spoken of as 2 :6-diketo-4-isopropylhexamethyleneis now called 4-isopropyl-dihydroresorcin, for though this and other similar substituted dihydro- resorcins behave as diketones towards hydroxylamine, there can be no doubt that their most usual form is the keto-enol modification repre- sented by the following formula : I]H2*C0 (CH,),CH* qHCH,*COH:CJH “58.6iOxonium salts of Buoran and its derivatives.” By J. T. Hewitt and J. N. Tervet. Fluoran (the phenolphthaleinanhydrideof Baeyer) and some of its derivatives have been examined as to their power of forming salts with strong mineral acids. The following salts have been prepared and examined : Rhoran nitrate, C,,H,,03,HN0, ; rnonosulphate, C,,H120,,H,S04; dimethyljhoran nnitrate, CI,2H,,0,,HN0, ;dimethyl-fluorun monosulphate, C,2H,,0,,H2S0, ; dimethylfluoran disulphats, C,,H,,U3,3H,SO, ;Juoyescein hydrochEoride, C,,H,,O,,HCl; fluorescein rnonosulphate, C,,H,,O,, H2S0,;fluorescein disuZphccte, C2,,H1,05,2H2S04, 87 "59.(( Influence of substitution on the reactivity of the aromatic metadiamines." By 6.T. Morgan, D.Sc. The successive introduction of methyl groups into the three positions adjacent to the nitrogen atoms of m-phenylenediamineis attended by a well-marked diminution in the reactivity of the diamine towards methylating agents, the action of methyl chloride or bromide being prevented when the substitution of the three hydrogen atoms is com-plete. m-Tolylenediamine (2 :4-diaminotoluene), like m-phenylenediamine, gives rise to a mixture of tertiary base and quaternary salt ;4 :6-di-amino-m-xylene yields the tertiary base as the sole product, whilst diaminomesitylene is not affected, These results agree with those obtained by Pinnow (Ber., 1897, 30, 3110; 1899, 32,1401 ;1901, 34,1139), and also by E.Fischer and Windaus (Ber., 1900, 33,345 and 1967). The tertiary diamines containing one free para-ortho-position with respect to nitrogen are very reactive substances, darkening on expo- sure, yielding unstable platinichlorides, and interacting readily with formaldehyde and the diazonium salts. 4 :6-Tetramethyldiamino-m-xyZene,which contains methyl groups in each of the para-ortho-positions, is a comparatively inert substance which is not darkened by exposure to light or air ;its platinichloride is stable, and the base itself does not condense either with formalde-hyde or diazonium salts, This diamine boils at 243-245" under 757 mm., and at 124-125' under 12 mm.pressure; its picmte crys- tallises in yellow prisms melting when suddenly heated at 202-203", but decomposing at 193-1 95O when maintained at this temperature for some time. 2 :4-TetrarnethyZdiaminotoZueneis a pale brownish-yellow oil boiling at 254-256" under 757 mm., and at 148-150' under 24-26 mm. pressure ;its sp. gr. is 0.9661 at 24" ;its platinichloride is decomposed by hot water ;the picrate crystallises from alcohol in yellow prisms melting at 162-163'. The metJLobromide, NMe,*c,,H,(CH,)NMe,*Br, produced together with the tertiary diamine in the methylation of m-tolylenediamine, yields a platinichloride, NMe,=C,H,( CH,)NMe,,HPtCI,, cry stallising in brownish- yello w scales.p-Nitrobenzene-5-mo-2 :4-tetrarnethyldianainotoZ.uene, resulting from the action of p-nitrobenzenediazonium chloride on 2 :4-tetramethyl-diaminotoluene, crystallises from alcohol or ethyl acetate in dark green leaflets with a bronze reflex and melts at 126 -127'. 2 :4 :2' :4'-0ctamethyZteti~amioditoZyZ-5;5'-methane, prepared by con- 88 densing 2 :4-tetrarnethyldiaminotoluenewith formaldehyde, crystal- lises from alcohol in colourless prisms melting at 86’; its picrate separates in spherical aggregates of yellow crystals and melts at 147-1 48’. 60. (( The influence of certain acidic oxides on the specific rotations of lactic acid and potassium lactate.” By Gc.Gc. Henderson and D. Prentice, Ph.D. The authors have examined the influence of antimonious, arsenious, and boric oxides on the rotations of aqueous solutions of potassium lactate and lactic acid, with the object of ascertaining whether any compounds of the tartar emetic type are formed in solution by inter- action of these substances. It was found that antimonious oxide is almost insoluble in solutions of potassium lactate, and that the rotations of the solutions are not appreciably affected by the presence of traces of antimonious oxide. Arsenious oxide and boric acid, on the other hand, were found to dis- solve readily in aqueous solutions of potassium lactate and lactic acid.The rotations of the solutions are altered by the presence of the dis- solved oxide, and in each case the maximum change occurs when the substances are present in the proportions requisite for the formation of an arseniolactate, (AsO)C,H,O,K, and a borolactate, (BO)C,H,O,K, respectively. The rotation of a solution of lactic acid is slightly diminished when arsenious oxide is dissolved in it, but considerably increased by the presence of boric acid. Experiments with molybdic and other oxides are in progress. 61. The amounts of nitrogen as ammonia and as nitric acid, and 6‘ of chlorine in the rain-water colleoted at Rothamsted. A report to the Lawes Trust Committee.” By N. H. J. Miller. Results of monthly determinations of nitrogen as ammonia and as nitrates in the rain-water collected during thirteen harvest years (September 1888 to August 1901) at Rothamsted, showed that the total nitrogen in these forms varied from 3.31 lbs.t,o 4.43 1bs. per acre per annum. The average amounts for the winter and summer months, and for the whole year, are as follows : Nitrogen per million Nitrogen per acre (lbs.) Rainfall as as as as (inches). ammonia. nitrates. ammonia. nitrates. Total. Winter ...... 14.32 0.381 0.175 1.233 0568 1.801 Summer ...... 12.93 0506 0.191 1.479 0.560 2.039 Year ... ..... 27.25 0.440 0.183 2.712 1.128 3.840 89 Of the total nitrogen 70 per cent. is present as ammonia and 30 per cent.as nitrates. During the summer months there is an increased production of ammonia, whilst the amount of nitric nitrogen (per acre) is nearly the same in summer as in winter. Chlorine has been determined monthly for twenty-four years. The average amounts are as follows : Rainfall Chlorine September 1877 to August 1901. (inches). per million. per acre (lbs.) Winter months ............ 14.65 3.05 10.12 Summer months ......... 14.13 1 *49 4.75 Year ........................ 28.78 2.28 14.87 The yearly amounts of chlorine in the rain vary considerably (maxi- mum 21.19, minimum 10.32 lbs. per acre). The variations depend less on the total rainfall for the year than on the amount of rain during the winter months. The rain falling at Rothamsted supplies, not only sufficient chlorine, but also enough sulphuric acid for the requirements of most crops.62. “The amounts of nitrogen, as nitrates, and chlorine in the drainage through uncropped and unmanured land. A report to the Lawes Trust Committee.” By N. I€.J. Miller The percolation through the 20, 40, and 60 inches of soil in the three Barnfield drain gauges amounted duriag 24 harvest years, Sept. 1877 to Aug. 1901, to 14.39, 15.30, and 14.41 inches per annurn, being 50.0, 53.2, and 50.1 per cent. respectively of the rainfall for the same period. The maximum and minimum drainage occur in November and June. The average loss of nitrogen, as nitrates, in the drainage is more than 30 lbs. per acre per annum, and about half of this loss takes place during October, November, and December.The yearly losses of nitrogen differ widely, according to the amount and distribution of the rain and drainage. This makes it difficult to form a decided opinion as to whether nitrification is less active at the present time than in earlier years. A very decided falling off is perhaps not to be expected in the near future. The soil of the 20-inch gauge is esti- mated to have contained, in 1870, as much as 6000 lbs. of nitrogen per acre, and of this amount only about 15 per cent. has been found in the drainage; in the case of the 60-inch gauge, the estimated loss is only 6.5 per cent. of the total initial nitrogen of the soil. In addi- tion to loss of nitrogen, there is, however, a considerable loss of lime, amounting to 11 lbs.per acre (or about 20 lbs. of calcium carbonate) per inch of drainage, and this loss may, as time goes on, be expected to influence the changes in the organic matter of the soils. 90 The average yearly amounts of chlorine per acre in the drainage is very similar to the amount found in the rain, but wide differences occur in some individual years. In the 24 years during which the chlorine has been determined, the soils of the 20-inch and 40-inch gauges have received from the rain 7.0 and 14.1 lbs. of chlorine per acre in excess of the amounts lost in drainage. The 40-inch gauge has lost 1'7.5 Ibs. of chlorine. 63. Benzylidenecamphoroximime." By 116. 0. Forster. An examination of a-aminocamphoroxime, described by Lapworth and Harvey (this vol., p.70), appears to have been undertaken with the object of investigating changes which substituted camphoroximes undergo in virtue of the presence of the oximido-group. This has been the author's aim in his study of camphoroxime, which has extended over several years, and contributions to the chemistry of P-chlorocamphoroxime, P-bromocamphoroxime, and a-benzylidene-camphoroxime have been already made. As Lapworth and Harvey have notified privately their intention to abandon the investigation, the author wishes to intimate that he proposes to continue the study of substituted camphoroximes. The following observations relating to benzylidenenamphoroxime are now put on record.Benzylidenecampkwoxime, C,?H,,ON, dissolves sparingly in boiling alcohol, and crystallises in transparent hexagonal prisms, melting at 197"; for a 2 per cent. solution in chloroform, [a]D= +389'. The benxoyl derivative crystdlises from petroleum in lustrous, well-formed prisms, and melts at 106-107"; for a 2 per cent. solution in chloro- form, [ = +246O. The phnylcarbanaate separates from alcohol in tufts of long, silky needles, and melts at 169O, when it evolves gas ; a 2 per cent. solution in chloroform has [a]D = +275". Nitrous acid converts benzylidenecamphoroxime into the compound, C17H2002N2, which melts at 117O, and gives Liebermann's reaction. Attempts to convert the oxime into benzylidenecampholenonitrile by the agency of boiling sulphuric acid (25 per cent.) have been un successful, but acetyl chloride gives gise to a nitrile which is un-saturated, and feebly lzevorotatory. The oxime is indifferent towards sodium amalgam, which reduces benzylidenecamphor to benzylcamphor, but sodium in boiling amyl alcohol reduces it to bases which probably represent the a-benzyl derivatives of bornylamine and neobornylamine ;the platinichloride from the dextrorotatory hydrochloride melts at 235O, whilst the platinichloride from the lzevorotatory hydrochloride melts at 247O.91 ADDITIONS TO THE LIBRARY.
