Yvon Villarceau then presented the elements and ephemerides of 
the planet 125, calculated by M. G, Leveau. This planet was

tion. —M. Maurice Lévy then communicated a paper on the 
theory of equations of partial differences of the second 
order of two independent variables.—Next came a con- 
tinuation of M. Th. du Moncel’s paper on the accidental

of certain substances in stopping putrefaction and preventing 
protoplasmic life, which was then read, and followed by a note

the causes of intermittent fevers, and the means of preven- 
tion and cure, by M. E. Ferriére—M. Picot then read a

skin, At the conclusion of the paper M. Emile Blanchard 
made some remarks on it as regards the Cayor fly, no specimens 
of which have yet reached Europe. M. Chevreul then presented 
a copy of M. Paul de Gasparin’s work on the ‘‘ Valuation of 
Arable Land in the Laboratory ;” and after some remarks from

Noy. 11.—M. Faye, President.—The first paper was by Capt. 
Perrier on the determination of a great geodesical base in Algeria. 
—The President followed with a paper on the triangulation of 
Algeria for the new military map of the province.—M. Becquerel 
_ then read the second part of his paper on the solar origin of 
atmospheric electricity. He considers that the protuberances 
come from solar volcanoes, and that they are charged with posi- 
tive electricity.—A letter from M. Faye to the author on his last 
. paper followed.—M. Le Verrier then read a note on the deter- 
mination of the secular variations of the elements of the four planets 
—Jupiter, Saturn, Uranus, and Neptune.—Next came a paper 
by M. Trécul on the origin of the lactic and alcoholic ferments. 
The author is very severe on M. Pasteur, who, he states, if 999 
experiments are favourable to spontaneous generation and one 
_ against it, adopts the one and rejects the 999. This, of course, 
drew a reply from M. Pasteur, and his reply an answer from M. 
Trécul.—M. Pasteur then read a note on M. Fremy’s paper read

‘two planets by M. Stephan, who had received information and 
observed them at Marseilles.—Next came a paper by M. H. 
Durrande on the acceleration in the displacement of a system of 
points which remains homographic with itself. At the conclusion 
of this came a paper on ‘‘ Chloride of Lime ” (bleaching powder), 
© by M.J. Kolb. The author gives a method of valuation of this 
important commercial product.—M. Balard then presented M. 
Scheurer-Kestner’s note on the loss of sodium in the preparation _ 
of soda-ash by Le Blanc’s process, The author decides that the 
loss occurs in the “ waste,” and augments with the excess of 
lime compounds,—M. Wurtz presented a note by M. G. Bou- — 
chardat on the neutral combinations of Mannite and its hydrates. 
—M. L. de Saint-Martin presented some researches on San-— 
tonin.—This was followed by MM. Legros and Onimus, with 
experimental researches on the physiology of the pneumogastric © 
nerve ; and by an account of ‘‘ Experimental Researches on the 
Functions of the Brain,” by M. E. Fournie.—M. Brogniart then 
presented MM, Renault and Grand’Eury’s paper on the Fossil
