The PRESIDENTsaid that he was authorised by the Council to make the following statement to the Society :-''The Council of The Chemical Society have received the following Memorial and enclosures. 2 Letter uddvessed to the Feellows by Messrs. Hm*den and Hurtog. OWENSCOLLEGE,MANCHESTER,October, 1897. DEARSIR,-We desire to ask if you will give your support to the enclosed Memorial to the Council of The Chemical Society, requesting them to propose such alterations in the Rules of the Society as will enable members who reside in the country to record their votes in the election for officers and members of the Council without personal attendance at the General Meeting, The reasoils for the change which we desire are explained in the Memorial itself, of which a draft is enclosed. That the change is practicable is shown by the fact that in Societies like the Society of Chemical Industry, the Institution of Civil Engineers, and the Institution of Electrical Engineers, each containing several thousand members, the regulations allow votes to be recorded by post, as me suggest, and the arrangements are such that the secrecy of the ballot is preserved. Should you approve of it, we should be much obliged if you would kindly sign and return the draft Memorial under cover to one of the undersigned at your early convenience.We are, dear Sir, Faithfully yours, ARTHURHARDEN. PHILIPHARTOG. Memorial. AND COUNCILOF THECHEMICALTo THE PRESIDENT SOCIETY. GENTLEMEN,-We the undersigned, Fellows of The Chemical Society, desire to draw your attention to the great change in constitution which has taken place since the Society was originally formed, and to the desirability of making some alteration in the Bye-laws, so as to corre-spond with this change. Whereas the Society was originally com-posed in the main of chemists living in London or its immediate neighbourhood, and until 1871 was called on its official publication The Chemical Society of London, since that date it has been called by the more general name (given in the Charter) of The Chemical Society, and at the present time the vast majority of the Fellows resides in other parts of the kingdom.Under the existing regulations it is, however, practically impossible for this majority to take any share in the government of the Society, since, under Bye-law V.,the vote of each member at the election of Officers and Council must be recordedpersonally, and may not be sent by post. It is of course recognised that a custom has grown up of choosing a 3 certain proportion of the Officers and Council from among the Fellows who reside in the provinces, but this practice cannot be regarded as a sufficient remedy for the defect in the existing Bye-law, and while we do not wish in any way to express dissatisfaction with the policy of the present or of past Councils, we feel strongly that the Council should be elected by the whole Society, and not by a mere fraction of the Fellows. In this feeling we venture to think that you will concur.We trust, therefore, that you will see your way to propose to the Society at an early date an alteration of Bye-law V. in the sense we desire, and have the honour to remain, Gentlemen, Your obedient Servants. (Signed by 540 Fellows.) Letter received by the Secretam’es, together with the Memorial and Enclosures. OWENS MANCHESTER,COLLEGE, December 16th, 1897.GmTLEr&m,-We beg to forward herewith a Memorial addressed to the President and ,Council of The Chemical Society, together with the signatures of over 500 Fellows appended thereto. We also enclose a list of the signatures divided into two sections ;(a) a list of the signatures appended to the Memorial in the first instance-ie., before it was circulated among the Fellows of the Society residing in the United Eingdom generally ; (b) a list of signatures appended subse- quently. With reference to the substance of the Memorial, we wish to make one statement. We are aware that in the Charter (on page 8 of the printed text) it is provided that ‘‘ at all general meetings and meetings of the Council, the majority present, and having theright to vote thereat respectively, shall decide upon the matters propounded at such meetings” ;hence in order to render legal the change desired, it would probably be necessary to obtain a Supplemental Charter, allowing members not actually present at meetings to vote by means ofballoting papers.It is in this connection material to point out that in order to obtain a revision of Bye-laws precisely similar to that now desired by Fellows of our own Society, a supplemental Charter was quite recently obtained by the lnstitution of Civil Engineers. We beg to request you to lay the accompanying Memorial and enclosures, and the present letter, before the President and Council of The Chemical Society, and have the honour to remain, Gentlemen, Your obedient Servants, ARTHURHARDEN.PHILIPHARTOG. The Xecretaries of The Chemical Xociety. 4 Owing to the action of the Bye-laws Committee, which was appointed some time ago, the Council is in a position to give an immediate answer to the Memorialists. The question of the power of the Society to alter the mode of election of the Officers and Council having arisen, the Bye-laws Com- mittee requested the solicitors of the Society, Messrs. Wilson, Bristows, and Carpmael, to submit the following case for legal opinion. Casefor the Opinion of Counsel. The opinion of Counsel is desired by the President and Council of The Chemical Society under the following circumstances :-A memorial is being extensively signed by the Fellows of The Chemical Society, addressed to the President and Council of such Society asking that the Bye-laws may be altered so as to allow the votes at the General Annual Meetings to be given by proxy.A printed copy of such Memorial is sent herewith. The attention of Counsel is directed to page 8 of the printed copy of the Charter of The Chemical Society, which is sent herewith, and also to pages 16 and 17 of such document. On the latter of which pages will be found the present Bye-laws on the subject. Counsel is desired to advise the President and Council of The Chemical Society whether, under their charter, they have power to alter the Bye-laws so as to provide for the votes at General Meetings being given by proxy. The following is the opinion of Counsel.Copy of Opinion of Mr. COZENS-HARDY,Q.C. I am of opinion that the Charter (p. 8) prohibits voting by proxy and that any Bye-law framed for the purpose of allowing voting by proxy would be repugnant to the Charter (p. 9) and invalid. HERBERTH. COZENS-HARDY. 7 New Square, Lincoln’s ha, December 6, 1897. This opinion of Mr. Cozens-Hardy, Q.C., makes it clear that the Council of the Society have not the power to propose such an alteration of Bye-law V. as the Memorialists request. The suggestion made by Nessra. Harden and Hartog in the letter addressed to the Secretaries along with the Memorial, that (‘it would probably be necessary to obtain a Supplementary Charter allowinq members not actually present at meetings to vote by means of bcclloting papers,” opens up questions outside the terms of the Memorial, which will necessitate further legal advice.The whole subject is receiving the most careful consideration of the Council.” 5 Of the following papers those marked * were read :-"1. "The preparation of pure iodine." By Bevan Lean, D.Sc.,B.A., and W,H. Whatmough. Stas, in his Nouvelles Recherches SUT les Zois des Proportions Chinziqzces, states that he was only able to find two methods of preparing iodine free from chlorine and bromine. One consisted in precipitating by water iodine dissolved in potassium iodide, the other depended on the decompositions of iodide of nitrogen by heat. Perhaps the main diffi- culty attached to these methods was the desiccation of the iodine and the removal of hydriodic acid, Neither in his published memoirs nor in his laboratory note-books has Stas stated how he assured himself that his "iodine " was free from other halogens.A few months ago the authors observed incidentally that no iodine is set free when cuprous iodide is heated, even at its fusion point, in a current of carbonic anhydride, although it is readily evolved when cuprous iodide is heated in air, oxygen, nitric oxide or nitrogen peroxide. The action is represented by the equation CU,~, +0, =2CuO+I,. No iodine is evolved when cuprous iodide is heated in a vacuum. The authors have examined the usual methods of preparing cuprous iodide. When a solution of cupric sulphate and a soluble chloride, bromide, or iodide, is saturated with sulphurous acid, cuprous iodide, bromide and chloride may all be precipitated; but there is so great a difference in their degree of solubility that, by securing a proper dilution, it is probable that cuprous iodide can be prepared free from cuprous bromide or chloride. A mixture of cupric sulphate and ferrous sulphate is still less liable to precipitate cuprous bromide and chloride along with cuprous iodide than cupric sulphate saturated with sulphurous acid.The authors have found that cuprous iodide can also be prepared by sprinkling iodoform in small quantities at a time upon a hot surface of copper. On account of the difference in the properties of chloro- form, bromoform and iodoform, it is probable that, by this method also, cuprous iodide can be prepared entirely free from bromide or chloride, If, moreover, the cuprous iodide is fused in a current of car- bonic anhydride or in vacuo, it can be freed completely from moisture. Iodine is most conveniently prepared from cuprous iodide by heating it in a stream of dry air at 220-240' and condensing the vapours upon a cold surface. Although the greater portion of the iodine in a given quantity of cuprous iodide is quickly expelled, it is not easy to expel the whole; after heating 1.7101 grams at 400' for 18 hours, 0.15 per cent.of the iodide was still undecomposed-otherwise the relation Cu2T,:2Cu0 could have been utilised for the exact measurement of tihe atomic weights of copper, iodine, and oxygen. The authors are 6 making further experiments upon this point.The action of air upon cuprous iodide is not dependent upon the presence of moisture. This is established -by sealing cuprous iodide in glass tubes in the presence of phosphoric anhydride. Iodine liberated as described from cuprous iodide at 240' leaves absolutely no residue when volatilised at 75'. If examined spectro- scopically, no evidence of the presence of copper can be found. The melting point (uncorrected) is 112*5-114'. Whether such iodine is as pure as that prepared by Stas or not, it appears desirable to redetermine the atomic weight of the element pre- pared by this method. DISCUSSION. Dr. SCOTTremarked that Stas depended on distillation two or three times with anhydrous baryta, and not on calcium nitrate, for the com-plete removal of water from his iodine.This reagent had also the great advantage of removing any traces of hydriodic acid, the calcium nitrate being only used for the removal of the greater part of the water. Although Stas does not give his methods of testing his iodine for traces of chlorine and bromine, his concluding remarks in that section of his paper evidently show that he had no doubts as to its purity. The marvellous agreement of his results with those of Marignac, who found 100 grams of silver gave 217.5334 of silver iodide, whilst Stas found in his complete synthesis 217.5335, will probably convince most chemists that both were dealing with the same chemical substance.Mr. R. J. FRISWELLasked if the author had observed the crystalline form and appearance of the sublimed iodine. He had himself a very interesting experience in this matter with iodine recovered from methyl iodide by Nicholson's method of recovering the iodine, used in methyl- ating rosaniline by mixing the sulphuric acid and sodium bichromate with the waste iodine liquor, the precipitated iodine being washed, pressed and fused under sulphuric acid. For many years he (Mr.Friswel1)hadnoticed that at times the sulphuric acid used for the fusion contained a mass of minute, violet-brown, glistening plates, but every attempt to collect; them failed, the least dilution of the acid causing them instantly to disappear. After some time, however, nearly a pound of a paste or magma of these crystals was obtained in the following way.The acid was allowed to dilute itself by the absorption of water from the air and then run off from the crystals; the magma of crystals was thrown on to a vacuum filter and washed with sulphuric acid of continually increasing dilution and at length with water ;the paste was then squeezed and, while moist, sublimed in a beaker covered with a loose glass plate at a temperature of 35--40". 7 At first, the ordinary violet plates of iodine appeared, with a little water, but these soon vanished and intensely black, adamantine, solid rhombic (?)crystals appeared. A brownish earthy residue was left. The crystals were of considerable size, a cubic mm.or so in content. He thought that since these had been obtained from iodine continually in use for many years, during which time some tons of iodine had passed through the operation, they might be the companion element which has been suspected, Prof. Ramsay was asked to examine the crystals and the paste from which they had been sublimed, but found that the adamantine crystals gave no residue on sub-limation and showed 99.84 per cent. iodine, the deficit being probably due to a slight accidental loss. On sublimation in a vacuum, both the plate-like crystals which first sublimed and iodine purified in the usual way left slight yellowish residues, but these adamantine crystals left none. They were, therefore, pure iodine.He wished to know whether the author’s substance resembled these crystals in any way. The PRESIDENTmentioned, as indicating the general trustworthiness of Stas’s observations, that he had recently confirmed Stas’s remsrk- able statement, that, when pure, solid iodine is opaque to light. Ha inquired whether Dr. Lean had made any experiments with palladious iodide. Dr. LEAN,in reply, said that he had not noticed anything anomalous in the crystallisation of the iodine. He had observed, however, that his iodine had a black and not a deep violet colour, and that it emitted no visible vapour at the ordinary temperature. Stas had made a similar observation. The reason he had not made most of his experiments with pal-ladious iodide was that it was so muc h more expensive than cuprous iodide.He had, however, made a few experiments which showed that iodine was very readily liberated when palladious iodide was heated in air. “2. Derivatives of bromtolylhydrazine.” By J, T. Hewitt, M.A., D.Sc,, and F. G.Pope. This is a continuation of the work of one of the authors on ortho-substituted phenylhydrazines. The hydrazine was prepared from the amido-compound by the method of Victor Meyer and Lecco (Ber., 1883, 16,2976) an alteration being made by pouring the solution of the diazonium salt into the stannous chloride solution. The free hydr- azine and the following salts and derivatives are described.

The reactions are being further examined. *3. "Researches on the terpenes. I. On the oxidation of fenchene." By John Addyman Gardner and GCeorge Bertram Cockburn. The authors give an account of their method of producing fenchene from fenchone, the oxidation products of fenchene, and pinene hydro- chloride. Fenchone, b. p. 191-192', m. p. 6", specific rotatory power [a]= +61" 58',was reduced to fenchyl alcohol by a modification of Wallach's method, using amyl alcohol and sodium instead of ethyl alcohol and sodium. It was obtained in hard, white crystals, m.p. 45', specific rotatory power [a]= -13" 38'. The fenchgl alcohol was converted into fenchyl chloride by the action of phosphorus pentachloride, and this into fenchene by saponifi-cation with aniline. The bulk of the fenchene thus obtained distilled for the most part between 150" and 156", several degrees lower than that described by Wallach, which boiled between 158' and 160'. A fraction 152-154" was shown by combustion to have the formula C,,H,,. Its specifio gravity was 0.8667 at 18' and specific rotatory power [a]= 9 -6"46' (not in solution). The specific gravity of Wallach's hydrocarbon was 0.864 at 20° and it was optically inactive. As a bye-product in the action of fenchyl chloride on aniline, the authors obtained a black oil, not volatile in steam.This substance did not solidify on standing, but on distillation under reduced pressure came over for the most part at 171-173" at 13 mm. pressure. It was a pale yellow, thick, viscous oil which turned black on exposure to air. Analysis showed it to have the composition C,,H17NHC,H,. On treatment with acetyl chloride, it yielded a thick, viscous oil of the composition C,,,H,,N(Ph) COMe. Fenchene was oxidised by heating it on the water bath with nitric acid (1 nitric acid : 1 water). When the oxidation was complete the liquid was distilled in steam, when some acetic acid was obtained. The residue was then evaporated to small bulk, and on standing crystals of cis-camphopyric acid separated out.After the removal of these crystals, the oily mother liquors were eventually distilled in vacuo. An acid oil and a neutral solid distilled over; these were separated by means of sodium carbonate, and the solid crystallised from alcohol. It proved to be camphopyric anhydride, m. p. 178". The yield of camphopyric acid obtained in these experiments was about 20 per cent. Turpentine hydrocbloride was heated on the water bath with nitric acid (2 nitric : 1 water). The oxidation was exceedingly slow, but after about 10 days the bulk of the hydrochloride had disappeared. The greater part of the acid was then distilled and contained a con-siderable proportion of acetic acid. The residue was then evaporated to complete dryness, dissolved in ether and the ethereal solution extracted with sodium carbonate.The acids extracted by the alkali were converted into insoluble lead salts. The lead salts were decomposed by sulphuric acid and extracted with ether. On evaporating the ether, an oil was obtained which on standing deposited crystals of camphoric acid ; the purified acid melted at 202-203", and its anhydride at 217O. The oil left after separation of these crystals was distilled in a vacuum; an oil distilled over between 120-130°, a smaller portion at 130-150°, and a considerable amount at 180-200°, which solidified on standing. This latter portion was purified by sublimation and crystallisation from alcohol, and proved to be camphopyric anhydride, an. p. 178". The yield of camphoric acid from 300 grams of turpentine hydro- chloride was 18 grams, and of camphopyric anhydride 8-9 grams.The authors were unable to isolate any camphoic acid. 10 4. “The action of alkalis on amides.” By Julius B. Cohen, Ph.D., and Charles E. Brittain, B.Sc. The authors have succeeded in preparing a series of compounds of the general formula R‘NH*C,H,O*NaOH and R”HC,H,O*KOH, by the action of the caustic alkalis on amides under certain conditions. These substances are analogous in their mode of formation and in pro-perties to the alcoholntes previously described (Cohen and Archdeacon, Trans., 2896, 69, 9), and probably poss.ss a similar constitution, which R’-N-Namay be expressed by the formula Me*6<::* 5. (‘The formation of monomethylaniline from dimethylaniline. ” By Julius B,Cohen, Ph.D., and Harry T.Calvert, B,Sc. When phenylnitrocarbinol (Trans., 1897,71, 1050) acts on dimethyl- aniline, a violent reaction occurs and the dimethylaniline is converted into nitrosomethylaniline, and at the same time nitrogen is evolved and benzylalcohol and benzaldehyde are formed. As phenylnitrocarbinol readily evolves nitrous fumes on standing and reacts in some cases like nitrous acid, this result suggested the possibility of a similar reaction occurring when nitrogen trioxide acts upon dimethylaniline. The latter action is, however, entirely distinct from that of phenylnitro-carbinol or nitrous acid, and will form the subject of a future com- munication. 6. Note on the aluminium-mercury couple.” By Julius Cohen, Ph.D., and Harry T.Calvert, B.Sc. The authors find that when aluminium is amalgamated with mercuric chloride, a small quantity of chlorine is retained by the aluminium and is probably present as oxychloride. The presence of the chlorine first became evident in the process of reducing a nitro-compound in neutral solution, when, instead of the free base, the hydrochloride was formed. 7. “Action of chloroform and alkaline hydrolriders on the nitro- benzoic acids.” By Walter J. Elliott, M.A. The author finds that the meta- and para-acids are reduced to the corresponding azoxy-a cids, while the ortho-acid is not appreciably affected. 11 ADDITIONS TO THE LIBRARY. I.
