[May 31, i^oo 



Report on works presented by M. Marx. — Remarks on an 

 eruption of the volcano Mayon in the Isle of Lucon, by the 

 French Consul for the Philippines. — On the convergence of the 

 coefficients in the development of the perturbation lunction, by 

 M. A. Ferand. — Remarks on a memoir of M. Masfau on the 

 graphical integration of some partial differential equation^, by 

 M. J. Coulon.— On a remarkable point in relation wi h the 

 Joule-Thomson effect, by M. Daniel Berthelot. The point 

 at which the inversion of the Jcnile-Thomson effect occurs is 

 deduced by a graphical construction from the data of Aiuagat, 

 and the result compared with some recent calculations of M. 

 Van der Waals. — On the distrlDution of currents and poten- 

 tials in the periodic state set up in the length of a sym- 

 metrical polyphase line presenting capacity, by M. Ch. Eug. 

 Guye. — On resonance in wireless telegraphy, by M. A. Blondel. 

 — Communication by wireless telegraphy with the aid of radio- 

 conductors with polarised electrodes, by M. C. Tissot. — On 

 anhydrous calcium diox'de and the constitution of its hydrates, 

 by M. de Forcand. A thermochemical paper. — On some pro- 

 perties of aluminium, and on the preparation of gaseous hydrogen 

 phosphide, by M. Camille Matignon. Details are given show- 

 ing how to burn aluminium in steam, carbon monoxide and 

 dioxide, oxides of nitrogen, formic acid, sulphur dioxide and 

 other gases and vapours. The preparation of crystallised 

 aluminium phosphide is described, from which pure PH3 can be 

 readily obtained. — Combinations of lithium bromide with am- 

 monia, by M. J. Bonnefoi. — The compounds LiBr.NHg, 

 LiBr.2NH3, LiBr.3NH3, LiBr.4NH3 are indicated by a 

 study of the dissociation pressures. The application of the 

 Clapyron formula to these data gi\es values for the 

 heats of dissociation of these compounds in good 

 agreement with the direct thermochemical measurements. — On 

 two polysulphides of lead and copper, by M. F. Bodroux. The 

 compounds PhSg and Cu,2S5 are described. — On a mercury 

 chlorosulphide, by M. F. Bjdroux. A chiorosulphide, 

 HgaS,;^. HgCl2) can be prepared, which is stable at ordinary 

 temperatures. — Action of water upon mercurous sulphate, by 

 M. Gouy. — Partial synthesis of Isevo-rotatory erythritol, by 

 M. L. Maquehne. Wohl's method is applied to xylose, the 

 steps being xylosoxime, acetylxylonic nitrile, erythose-aceta- 

 mide, and eiythrite. — Preparation of the dialkylamido-dichloran- 

 thraquinones, by M. E. C. Severin. — On a monoiodohydrin of 

 glycol, by MM. E. Charon and Paix-Seailles. — On 7-chloro- 

 crotonic acid, by M. R. Lespieau. A description of the pro- 

 perties of CH2Cl.CH:CH.C02lI, its nitrile and ethyl ester.— 

 On the composition of the albumen of the St. Ignatius bean and 

 of the«?<x vomica bean, by MM. Em.Bourquelotand J. Laurent. 

 The albumen from these beans yields the same carbohydrates, a 

 mixture of a mannane and a galactane, as the albumen of legu- 

 minous beans previously studied. In nux vomica the proportion 

 of galatose found on hydrolysis is very high. These beans, in 

 fact, serve as an advantageous source of crystallised galatose. 

 — Experimental researches upon the evolution of the lamprey, 

 by M. E. Bataillon. — ^Remarks upon certain points in the life- 

 history of the lower organisms, by M. J. Kunstler. — On some 

 new Synclavellse in the compound Ascidians, by M. Maurice 

 Caullery. — Analysis of marine dej^osits collected off Brest, by 

 M. J. Thoulet. — The mineral matters in the human foetus 

 during the last five months of pregnancy, by M. L. Hugonenq. 

 — Identity of a bacillus from milk with the pneumobacillus of 

 Friedlsender, by MM. L. Grimbert and G. Legros. The com- 

 plete identity ol these bacilli was shown by a comparative study 

 of their general biology and morphology, and of their action 

 UDon carbohydrates.
