PARIS. Academy of Sciences, June 24.—Marcel Brillouin: Movements of the oceans. The Newtonian potential of the ridge in cylindrical co-ordinates.—B. Cabrera and A. Duperier: The paramagnetic properties of the rare earths. Details of measurements of the variations of the magnetisation coefficients of suiphates and oxides of the rare earths between 20°C. and 400°C. The Curie-Weiss law applies to some of the rare metals, but not to all.—F. E. Myard: The correct control of a motor-car.—Bertrand Gambier: Geometrical configuration of right lines or circles.—S.

Delsarte: A fundamental problem of the theory of vortices.—R. Wavre:A desideratum formulated by Tisserand and the theory of planetary figues.—Marcel Chopin: High temperature determinations of the specific heat of nitrogen and carbon dioxide. The method used aims at the nearly complete elimination of the corrections in a calorimetric measurement of the specific heats of gases at high temperatures. For nitrogen,
