Abstract
PARIS. Academy of Sciences, August 6.—M. H. Poincaté in the chair.—The iodomercurates of sodium and barium: A. Duboin. The author has isolated crystals of the double iodide of sodium and mercury, having the composition 2 NaI, HgI2, 4 H2O, and of the corresponding barium compound, BaI2, HgI2, 5 H2O. The latter crystals were remarkable for their length, approaching 2 cm.—The borostannates of the alkaline earths: the reproduction of nordenskiöldine: L. Ouvrard. Calcium borostannate, possessing crystallographic characters identical with those of the natural mineral, was obtained by heating precipitated calcium borate with tin dioxide to a white heat in a slow current of hydrogen chloride.—The influence of the temperature of dehydration of alabaster on the setting of the plaster obtained: E. Leduc and Maurice Pellet.—The causes of the appearance of so-called anomalous forms in plants: P. Vuillemin.—Researches on the gaseous exchanges of a green plant developed in the light in the absence of carbonic acid, in a soil to which arnides have been added: Jules Lefévre. Under the above conditions it has been found that a green plant can develop, increasing its dry weight three times, without any oxygen being given off.— The action of the X-rays on the ovary of the dog: M. Roulier. Contrary to the results obtained with rabbits, atrophy of the ovary is very difficult to obtain, in spite of the production of serious lesions of the skin.—Experimental nagana. The variations in the number of the trypanosomes in the blood of the dog. The intravascular trypanolysis and trypanolytic power of the serum: A. Rodet and G. Vallet.
