Abstract
PARIS Academy of Sciences, March 23 (CM., 202, 993–1124). EBNEST ESCLANGON: The application of the principle of relativity to the study of a dynamical problem. MARCEL DELPINE and ALAIN H–RE ALT: The hydrog©nation of carbonyl compounds by Raney nickel, coated with metals of the platinum family. The influence of alkalis. The presence of a trace of alkali is essential for the hydrog©nation. Experiments were made with ruthenium, palladium, osmium, iridium and platinum as coating for the nickel. All these metals increase the velocity of addition of hydrogen, palladium being the least active, platinum, iridium and osmium the most active. LUDOVIC MRAZEC was elected Correspondant for the Section of Mineralogy, in succession to the late H. F. Osborn. B. HosTEsrsKY: Probabilities in chain.
