Abstract
PARIS. Academy o! Sciences, August 18.—M. Léon Guignard in the chair.—G. Humbert: The particular representations of an integer by positive forms of Hermite in an imaginary quadratic body.—H. Andoyer: The development of a general function of the radius vector of the eccentric anomaly in elliptic movement.—E. L. Bouvier and d'E. de Channoy. Mutation of a Caridina into an Ortmannia, and general observations on the evolutive mutations of fresh-water shrimps of the family of the Atyidæ.—E. Kogbetliantz: Ultraspherical series.—R. Gamier: Vectorial, fields with indeterminate asymptotic directions.—E. Jougnet: A problem of generalised hydraulics. Flow of a burning, gaseous mixture.—A. Véronnet: Ellipsoidal figures of equilibrium of a liquid in rotation; variation of, the major, axis.—G. Fayet and A. Schanmasse: The next return of the periodic comet 1911 VII. (Schaumasse). Taking into account the perturbations in the orbit caused by the proximity of the comet to Jupiter, in 1913, new elements have been worked out. It should be sought for in the beginning of September.—R. Baillaud: An impersonal photographic astrolabe.—P. Nicolardot: The action of reagents upon glasspowder. Eight kinds of glass were studied, and the amounts dissolved by pure water and decinormal hydrochloric acid determined for three grades of powder, fine, medium, and coarse.—S. Posternak: The saturated sodium salt of inosite hexaphosphate. A correction of data given in an earlier paper.—Ch. Boulin and L. J. Simon: The evolution of a mixture of methyl sulphate and chlorosulphonic acid.—J. Bougault and P. Robin: The oxidation of benz-aldoxime. This oxime, on treatment with iodine and sodium carbonate, gives benzoic acid, benzaldoxime peroxide, benzoyl-benzaldoxime, and dibenzenyl-oxoazo-oxime.
