Abstract
PARIS. Academy of Sciences, October 20.—M. F. Guyon in the chair.—Pierre Termier: The AI excursion of the twelfth International Geological Congress: the Appalachian region of Canada.—R. Lépine and M. Boulud: The presence, in the vascular walls, of a ferment setting free a reducing sugar at the expense of the virtual sugar of the blood, and capable of hydrolysing phloridzin. These experiments show that the vascular walls possess a new function, hitherto ascribed to the liver alone.—éeon Lichtenstein: Some applications of the notions of functions of an infinity of variables in the calculus of variations.—Frangois Lukács: Laplace's series.—Pierre Idrac: Experimental researches on the vol “plané. Photographic experiments with small balloons show that in places where birds are capable of hovering flight there is an ascending current of air with velocities of the order of 3 to 4 metres per second. This corresponds to the magnitude of the velocity of air currents in the vol plané of an aëroplane.—R. Fortrat: An abnormal Zee-man phenomenon, with the sodium doublet, λ = 2853. iThe use of a ferro-cobalt electromagnet, made according to the indications of P. Weiss, enabled the author to place an ordinary spark in a field of 49400 Gauss. The experimental results obtained agree closely with the theory of Voigt.—Raoul Dupuy: Functional arterial hypertensions. Pseudo-arterio-sclerosis. A discussion of the means of differentiating arterio-sclerosis from functional hypertension.—P. Chaussé: The path of penetration of the tuberculous virus in the calf and the tuberculigenic power of cow's milk. Inhalation is the usual mode of tuberculous infection in the young calf; intra-uterine infection must also be taken into consideration, since the latter furnishes an important proportion of the graver cases. Although the calf is much more exposed than the adult animal to infection through the alimentary canal, this is relatively the least important mode of infection. The milk of the cow is not the cause of infection of the calf to any great extent.—J. Danysz: The use of some new medicinal combinations in the treatment of trypanosomiasis. A compound obtained by the action of silver nitrate upon arsenobenzene, was found capable of sterilising the blood of rabbits infected with Surra by a single injection. Trypanosoma rhodesiense was more resistant but succumbed to a mixture of the above reagent with trypan red.—Jules Amar: The physiological effects of work and the degree of fatigue.—R. Anthony: The experimental study of the factors determining the cranial morphology of mammals deprived of teeth.— J. Chaine: The îlots of the Termites.— M. Lemoigne: The butylene-glycollic fermentation of glucose by staphylococci.—Lucien Mayet and Jean Pissot: The discovery of the engraved bone of a mammoth showing a human figure, in the upper Aurignacian layer of La Colombiere, near Poncin. The drawing described would appear to be the first engraving of man of the middle Quaternary epoch.—Jean Boussac: The geological constitution of Haute-Tarentaise.—F. Dienert: Remarks concerning some experiments with fluorescin.
