P R 0CE E D 1.NG S OF THE CHEMICAL SOCIETY. No. 91. Session 1890-91. January 15th 1891. Dr. W. J. Russell, F.R.S., in the Chair. Certificates were read foy the first time in favour of Messrs. Henry Austin Appleton, 19, South Street, Middlesbro’ ; John Charles Aydans, 44,Crescent Road, Plumstead, S.E.; Clayton Beadle, Bead- onweil, Belvedere, Kent ; Thomas Byrne, Glenville, Dundrum, co. Dnblin ; Arthur Cole, B.A.,Holmleigh, Charles Street, Berkhamsted ; Reginald Lorn Marshall, 25, Lancaster Park, Richmond ; Tom Kirke Rose, 9, Royal Mint, E. ; R. Greig Smith, Springwells, New Street, Musselburgh ; Howard C. Sucrt5, Breeze House, Higher Uroughton, Manchester ;Matthew Carrington Sykes, Sykesli urst, Barnsley, Yorks ; W. Will, Ph.D., 1,Beethoven Strasse, Berlin, N.W.The following papers were read :-1. “ Magnetic rotation.” By W. Ostwald. The magnetic rotation of organic compounds, according to Perkin, is an additive function of their composition and equal to the sun1 of the rotations of the components, but this is not the casc with the rotation of inorgan’ic compounds, which is usually found greater than that calculated on such an assumption. In the case of hydrogen chloride, for instance, the calculated value is about 2.18, and as a matter of fact the value obtained for hydrogen chloride dissolved in an organic solvent, isoamyl oxide, is 2.24, but when disolved in water the value found is from 4.05 to 4.42, increasing with the dilution. The author points out that lhese exceptional values are only obtained in the case of electrolytes, and that tbeymust therefore be referred to afundamental difference existing between the constitution of electro-lytes and that of non-conductors.That such a difference exists has been already deduced from other considerations, and has led Arrhenius 2 to the formulation of the theory of electrolytic dissociation. The aut,hor clainis that the facts established with regard to niagaetic rot'ation are in perfect accordance with this theory, and that any exceptional values in the magnetic rotations of electrolytes are due to the occurrence of electrolytic dissociation. DISCUSSION. Mi-. PICKERINGsaid that in Professor Oatwald's attempt to nppro-priate Dr. Perkin's results on the magnetic rotation of solutions of electrolytes in support of the dissociation theory, no attempt, WHS made to explain what connection should exist between the niagnetic rotation and the supposed dissociation into ions, but it was boldly stated that if, a8 in the case of hydrogen chloride, the magnetic rota- tion and dissociation both increased with dilution, the result proved the truth of the dissociation theory, while equal support to this latter theoiy was afforded if, as in the case of sulphuric acid, dilutiou diminished the rotation and increased the dissociation ; and the most astonishing part of the argument appeared to be that the nearly double magnetic rotations obtained in some cases should be brought forward as a proof of dissociation, when the observations were iiiade on solutions so strong that the dissociation theory represents tlieni 21,s containing hardly any dissociated substance at a11.Surely thc 1:atural conclusion to draw froni sucli a doubling when it occurs iii the absence of dissociation would be that it could not be explained by dissociation. 2. ('The vapour density of ammonium chloride." Ry Frank Pullinger, B.A., B.Sc., and J. A. Gardner, B.A. The authors have made experimeiits at various temperatures 011 the vapour density of ammonium chloride. The appaisatus used was that of Victor Meyer. In view- of the well-known results of Wurtz concerning the vapour density of phosphorus pentachloride, it was decided to vaporise the ammonium chloride into an atmosphere of ammonia-one of the products of dissociation.In the first instancc the experiments were conducted at a moderate red heat and the salt was vaporised ixto air. The mean result of five experiiiients was 0.926 ; the calculated value for complete dissociation is 0.921. At 1040" C.(the temperatare of boiling zinc), Deville and Troost,, using Dumas' method, found the vapour density to be 1.000. Boiling sulphur was next used, giving a temperature of 448" C. The salt was first vaporised into air. The values found were 0.983 and 0.932. The air was then displaced by ammonia, and the values obtained were 0.939, 0.994 aiid 1.009. 3 At a temperature of 360” C. (that of boiling anthracene), the rela- tive density in an atmosphere of air was 0,944, while in an atmosphere of ammonia it was 1.128 and 1.141.It is evident that in this latter case the ammonium chloride was not wholly dissociated. It was found impossible to vaporise the salt into ammonia at 300” C. in a bath of boiling a-naphthylamine, In one case, 0.0175 gram of ammonium chloride was heated for 40 minutes, but the loss in weight during that time was only 04045 gram, and the volume of ammonia expelled from the apparatus was only 0.91 C.C. In another experiment, 0.0037 gram was taken, and the loss during 40 minates was 0.0021 gram, no gas being expelled. The vaporisa- tion into air, however, goes on with comparative rapidity at this temperature, and the values found were 0.982, 0.986 and 0.985. The time taken for expulsion of the air was 10-12 minutes.At a temperature of 354” C., Deville and Troost, using a bath of mercury vapour, found that the vapour density was 1.01. T1:e authors propose to continue their experiments at temperatures betmeen 300” and 360”. 3. ‘‘ Chlorinated phenylhydrazines.” By J. T. Hewitt, B.A.,B.Sc. The author describes the following compounds :-Orthochlorophenylhydruxi~~e, and its hydrochloride. CZC6H,*NH*NH2, OrthochZoropheny Zsemicar bazide, C1 C,H,*NE€*NH*C 0-NH,. Orthochlorophenylphenylsemit hiocar baxid e, C1 CsK,-N,H,*C S*NH Ph. Orthoch loropheny lhydmainepyruvk acid, ClC6H4.N,B,*C~e-COzH. Yarach1orophen~lpl~enylsenzithiocal.baz~~~e.

Diparachloropheny lzhrea, c0(Nfi * C6H,C!1) 2.The compounds formed by interaction of aldehydes 01-ketones and orthochlorophenylhydrazine, according to the author, are very unstable. 4. “A new modification of phosphorus.” By H. M. Vernon, Scholar of Merton College, Oxford. Observations on the rate of rise of temperature of phosphoriis mid other experiments have led the author to the conclusion that one or other of two different modifications of phosphorus may result when fused phosphorus solidifies ; the new variety is formed when tlhe phosphoras is cooled below its solidifj-ing point and then solidified, mid has an undefined melting point; the ordinary variety of well- 4 defiued melting point being formed when solidification of the phosphorus sets in directly the point of solidification is reached without the temperature sinking below this point.From examination of crystals under the microscope, the author considers that the new variety crystallises in rhombic prisms, the ordinary crystallising in octahedra; he summnrises the properties of the two modifications in the following table :-Octahedral var2t.y. Rhombic vaviety. Has a definite melting point at 44-3". Has no well defined melting point; melts at about 45 -3'. Relative density at 13', 1.8177. Has a Relative density at) 13", 1.82'12. considerably greater latent heat of fusion than rlioinbic variety. Solidifying point 43.8'. Solidifying point 43.8".DISCUSSION. Mr. PICKPRINGthought that Mr. Vernon's conclusions must be accepted at present with great reserve. A difference of 1"in the melting points, especially where one of these melting points wa,s undefined, might easily be accounted for by the presence of dissolved matter, accidental impurity, products of oxidation, or some of the oil used to cover the molten phosphorus. Mr. Vernon's curves seem to prove conclusively that this was the case, for that portion which represented tlie temperature of the substance while it was melting was very much curved, instead of being horizontal as it would be if the phosphorus had been pure. The small difference in the densities -0.01-was equally unsatisfactory, and even if any conclusion could be drawn from a superficial examination of the cryst'als under the micromope, it would be invalidated by the fact that the specimens exaniiiied had both been dissolved in, and reciytallised from, benzene, for, since fusion had been shown to render the two supposed varieties identical, it was more than probable that dissolution would do the same.It was noticeable that although the two modifications were supposed to be obtained by cooling fused phosphorus, yet the fused phosphorus solidified in each case at tlie same temperature, a tempe-rature which was not identical with the melting points of either of the supposed varieties. Mr. TUTTOKconcurred with Mr. Pickering in considering that such an important, conclusion as to the existence of a new variety of phos-phorus was not justified by the data brought forward. It is well lmown that phosphorus is a substance which exhibits the property of superfusion in a high degree, and the thermal disturbance caused bp the sudden solidification of a superfused mass would be likely to influence the results of a determination of melting point made after 5 solidification under such circumstances.In the speaker’s own experiments on the fusion of phosphorous oxide, which also exhibits superfusion in a very marked manner, a determination of melting point after such solidification from a state of superfusion frequently yielded values differing sometimes by a whole degree from the true melting point of the substance. It is not at all surprising that a difference of a degree should have been observed by Mr.Vernon, but this fact in itself could scarcely be said to furnish proof of the existence of two modifications. The speaker also took exception to the arbitrary manner in which, from a microscopical examination of which absolutely no details are given, it was concluded that the supposed new modification crystallised in rhombic prisms. Remem-bering t,hat many really isotropic substances frequently exhibit polarisation colours, owing to their deposition probably in a slight state of strain, it would not be surprising if regular crystals of phosphorus were to exhibit polarisation. It is certainly necessary to have, at least, data concerning t.he mode of extinction of the crystals and their behaviour in convergent light before any conclusion cau be arrived at as regards their crystalline system.CERTIFICATES OF CANDIDATES FOR ELECTIOK AT THE NEXT BALLOT.
