PARIS Academy of Sciences, August 27.—M. Blanchard, president, in the chair.—A telegraphic despatch received by M. Dumas, through M. Pasteur, from the French Cholera Mission in Egypt, announces several important discoveries of a constant character, which will be communicated in detail later on.—New researches on the mode of action of the antiseptics used in staunching sores, by M. Gosselin. From experiments made on rabbits and frogs, it results that phenic acid, camphorated spirits, and similar solutions, are useful in two ways, partly by destroying germs, and thus preventing putrefaction, partly as astringents, by coagulating the albumen of the blood.—On the law of sequence in the evolution of the first vessels in the leaves of the Cruciferæ (second part), by M. A. Trécul.—Astrophotographic studies, by M. Ch. V. Zenger.—On the production of the fundamental telluric groups A and B of the solar spectrum by an absorbing layer of oxygen, by M.

Callandreau.—On the measurement of time; a reply to the observations of E. J. Stone, by M. A. Gaillot.—On a formula relative to the velocity of waves; a reply to M. Gouy, by Lord Rayleigh. In the Comptes Rendus for May, 1882, M. Gouy, referring to Lord Rayleigh's correspondence in NATURE during the year 1881, recalls a memoir previously published by him in the Comptes Rendus for November, 1880, in which occurs the formula.
