Abstract
PARIS. Academy of Sciences, July 8.—M. P. Painlevé in the chair.—The president announced the death of Charles Wolf.—G. Bigourdan: Notice on the life and work of Charles Wolf.—G. Humbert: The representations of an integer by indefinite, ternary, quadratic forms.—C. Richet, P. Brodin, and Fr. Saint-Girons: The effects of isotonic intravenous injections in hæmorrhage. From experiments on dogs in cases of grave hæmorrhage the authors recommend extensive intravenous injections. The percentage of red corpuscles is lowered, but the mass of the blood is increased.—G. A. Boulenger: The relations of ontogeny to taxinomy in Batrachians.—MM. Dimier and J. Bergonié: The search for the guinea-worm by radiography. This parasite can be detected by the X-rays.—R. Jonckheere: Observations and identification of the new star in Aquila. Observations of magnitude were made on June 8, 9, 10, 11, and 12. The new star has been identified with one recorded on photographs taken at Johannesburg (August, 1910) and at Algiers (August, 1909, and June, 1895).—A. Véronnet: The maximum temperature of a star undergoing condensation.—A. Leduc: The density, compressibility, and atomic mass of argon. The numbers for density and atomic mass do not differ appreciably from those given by Ramsay and Travers.—Q. Majorana: Experimental demonstration of the constancy of the velocity of light emitted by a moving source. The source of light was a rotating mercury arc, with a peripheral velocity of 90 metres per second, and the light was examined by a Michelson interferometer.—P. Weiss: A property of ferro-magnetism.—P. Boucherot: Calculation of the propagation of alternating currents on long lines by the separation of the real and reactive powers.—E. Bélot: The experimental reproduction of mountain folds on the hypothesis of a horizontal displacement of the internal layers.—L. Gentil: The extension into Andalusia of strata in the province of Cadiz.—P. Wintrebert: The disjunction of the nervous and muscular functions at the period of latent automatism in the embryos of Scyllium canicula.—H. Marichelle: The theory of vowels and its applications to auditive re-education.—E. Maignon: The influence of the species of animal on the toxic power and mode of utilisation of the food proteins. The foods employed were white of egg, casein, and meat-powder; the effects on the dog and white rat are compared.—P. Portier and H. Bierry: The importance of the ketonic function in metabolism. Ketone formation by symbiotes. The pentoses (ara-binose and xvlose), the hexoses (glucose, levulose, galac-tose, sorbose), the bioses (saccharose, etc.), and certain polyalcohols (glycerol, mannite) are, in suitable media, attacked by symbiotes, giving, besides other products, acetyl-methyl-carbinol, CH3COCH(OH)CH3.—M. Heitz-Boyer: The mechanical reduction of fractures.—M. Quénu: Remarks on the preceding communication.
