Societies and Academies

PARIS. Academy of Sciences, August 22.—M. Emile Picard in the chair.—The president announced the death of M. Eugène Rouché.—Paul Sabatier and A. Mailhe: The catalytic preparation of the phenolic oxides and the diphenylenic oxides. The authors have applied the catalytic properties of thoria to the preparation of phenyl ether and its homologues. The thoria is maintained at a temperature of between 390° C. and 450° C., and the vapour of the phenol passed over it. The yield is good; but if the temperature is raised another reaction, characterised by the elimination of hydrogen, takes place, ihe oxide of diphenylene being formed. The reaction applies to the cresols and xylenols.—J. Guillaume: Observations of the sun made at the Observatory of Lyons during the second quarter of 1910. Observations were possible on fifty-four days, and the results are recorded in tables showing the number of spots, the distribution of the spots in latitude, and the distribution of the faculæ in latitude.—M. Schaumasse: Observations of the Metcalf comet made at the Observatory of Nice with the bent equatoriai of 40-cm. aperture. The comet appears as a nebulosity of the tenth magnitude, with a well-marked condensation.—Michel Fekete: A theorem of M. Landau.—C. Maltézos: The real image of Purkinje.—L. Fondard and F. Gauthié: The composition of carnations with flexible stems and rigid stems. Three American varieties of carnation with rigid stems, and one French variety with flexible stems, have been analysed, and the differences in the stiffness of the stems found to be accompanied with distinct differences in composition.—Ed. Hesse: Trypanoplasma vaginalis, a new species found as a parasite in the vagina of the leech.—E. Roubaud: A Bombex preying on the Glossina of Datiomey. This wasp is one of the very small number of species known to capture the mosquito.
