Abstract
PARIS. Academy of Sciences, August 17.—M. Bouquet de la Grye in the chair.—The synthesis of unsaturated fatty ketones: F. Boudroux and F. Taboury. Calcium carbide attacks the ketones of the fatty series. Acetone gives mesityl oxide and other condensation products; butanone is dehydrated in a simpler manner, the unsaturated ketone C2H5.C(CH3)=CH—CO.C2H5 being formed.—The influence of the reaction of the medium on the development and proteolytic activity of Davaine's bacteridium: Mile. Eleonore Lazarus. The limits of acidity or alkalinity between which it is possible for the organism to develop, as well as the reaction corresponding to the maximum proteolysis, depends, not only on the strain, but also on the nature of the food material.—The mitochondria of the muscular fibres of the heart: Cl. Regaud.—The geological history of the Tellian Atlas of eastern Numidia (Algeria): J. Dareste de la Chavanne.
