Abstract
PARIS. Academy of Sciences, July 15.—The president announced the death of Albert A. Michelson, foreign associate.—Ch. Fabry: An interferential level without an air bubble. A liquid, preferably oil, is contained in a vessel the bottom of which is a platinised glass spherical surface of very large radius (500 metres). By means of the interference rings produced, this can be used as a level of high precision.—C. Camichel and P. Dupin: The various modes of contraction of a liquid stream at the commencement of an efflux.—Henri Lagatu and Louis Maume: The variation of the physiological relations between the mineral constituents of a plant species.—M. Ghermanesco: The n-metaharmonic functions. René Pallu: Study of the system H3PO34, Ba(OH)2, CO2, H2O.—Agostino Puppo and Pietro Longo: The storm of July 24, 1930, in the Treviso-Udine district. A correction of a misprint in the Comptes rendus, June 8, 1930. A. Guilliermond: The mode of formation of the anthocyanic pigments in the flower of Iris germanica. The anthocyanic pigments in the flower of I. germanica are preceded by the production of oxyflavonols.—Léon Binet and J. Magrou: Sulphur and growth. The high proportion of glutathione in tissues during the period of proliferation suggested a study of the influence exerted on growth by various sulphur compounds. The activating action of sodium hyposulphite on growth has been demonstrated in the case of cress and of the tadpole.—C. Levaditi, J. Bardet, A. Tchakirian, and A. Vaisman: The distribution of gallium in the organism. From the point of view of its distribution in the blood and tissues (rabbits) gallium behaves like bismuth, tellurium, and mercury.—Bordier: The remarkable action of diathermic d'Arsonvalisation at a distance.
