Abstract
PARIS. Academy of Sciences, September 22.—Général Bassot in the chair.—A. Chauveau: Comparison of vigorous and feeble organisms from the point of view of their aptitude for receiving and cultivating virulent organisms. According to the views at present generally held, a strong, healthy man is less readily attacked by tuberculosis or other contagious diseases than cases where the body has been weakened by alcoholism or other causes. This view is strongly controverted by the author, who refers to the experimental infection in 1868 of sixty healthy animals by tubercle; not one escaped the Infection Additional experiments on the transmission of scab to sheep are now given. Neither the healthy nor enfeebled subjects escaped.—T. Levi-Civita: Torricelli's theorem and the commencement of flow.—Edouard Heckel and Cl. Verne: Cultural bud mutations of Solanum immite, S. Jamesii, and S. tuberosum.—R. Lépine and Boulud: The intra-renal resorption of chlorides in various states of the kidney.—P. Chofardet: Observations of the Metcalf comet 1913b, made at the observatory of Besancon with tlte bent equatorial. Data given for September 7 and 11. The comet was of the ninth magnitude, nucleus badly defined, and no tail visible.—P. Chofardet: Observations Of the Neujmin comet 1914c, made at the observatory of Besangon with the coudé equatorial. Data given for September 10 and 11. The comet was of the eleventh magnitude, with a small brilliant nucleus and a nebulous tail.—D. Mirimanoff: Remarks on a communication of Eugène Fabry. Pointing out an error in a demonstration of Fermat's theorem.—Paul Lebard: Remarks on the affinities, of the principal genera of the group of ligulate flowers.—P. Mazé, M. Ruot, and M. Lemoigne: Lime chlorosis of green plants. Rôle of the root excretions in the absorption of iron from chalky soils. The presence of excess of chalk in the soil may produce chlorosis by rendering the iron insoluble. The addition of organic acids permitting the solution of small quantities of iron in presence of calcium carbonate removes the chlorosis at once.—Eugène Pittard: The comparative analysis of some of the body dimensions in; Tartars of both sexes.—Ch. Dhere and L. Hyncki: The absorption of visible and ultra-violet rays by carotinoid pigments.
