PARIS Academy of Sciences, September 27.—M. Wurtz in the chair.—The following papers were read:—On the non-recurrence of the anthracoid affection, by MM. Pasteur and Chamberland. Their experiments prove that in the case of charbon, as in that of chicken cholera, inoculations that do not prove fatal are preventive of a recurrence of the disease. M. Pasteur argues against M. Chauveau's theory that such non-recurrence is due to production of matters adverse to the proliferation of the bacterium. Experiments had been made with a view to testing a remedy for charbon devised by M. Louvrier, but were indecisive.—On the results obtained by M. Rondaire in his exploration of the Tunisian and Algerian ehotts, by M. de Lesseps. M. Rondaire's conclusions are entirely favourable to filling the basin situated between the Gulf of Gabes and the projected line of railway from Biskra to Tuggurt. This would make an interior sea about 400 km. in length and 1,600 km. in circumference.—A vapour-tension manometer for analysing liquids and measuring pressures, by M. Perrier. A glass tube, tapering at the lower end, stands with this (open) end in mercury, contained in, but not filling, an oblong closed bulb, a few drops of a volatile liquid being imprisoned above the mercury. The liquid to be determined is heated in a small boiler and the bulb referred to is placed in the vapour. The liquid of the manometer (which should emit vapour of greater tension than the liquids examined) acts by its vapour on the mercury, forcing it up the tube to various heights.— On a property of Poisson's function, and on the integration of equations with partial derivatives of the first order, by M. Gilbert.—On the theory of sines of superior orders, by M. Farkas.—On the invention of binocular telescopes, by M. Govi. The invention is commonly attributed to the Capuchin monk Schyrleus de Rheita, who published an account of it in 1645. M. Govi finds, from the papers of Peirescq in the Bibliothèque Nationale, that a spectacle maker in Paris, D. Chorez, made and presented binocular glasses to the king in 1625, i.e. twenty years earlier.—On the difficulty of absorption and the local effects of the poison of Bothrops jararaca, by MM. Couty and Lacerda. Whichever the mode of introduction, cellular, muscular, or serous tissue, brain, heart, or lung, and whatever the quantity of poison injected (vascular ruptures and antecedent wounds apart), there is no distinct sign of penetration of the poison into the blood. There is always local inflammation, which for some organs may prove rapidly fatal. The lung is most sensitive in this respect, the stomach and intestine least.—Study of the vertebræ in the order of Ophidians, by M. Rochebrune.—On the ciliated embryo of the Bilharzia, by M. Chatin. The signification assigned by helminthologists to this embryo in the cycle of development of the species requires (in the author's opinion) to be profoundly modified (a superiority of constitution being observed).—Researches on the presence of micrococcus in the diseased ear; considerations on the rôle of microbes in auricular furuncle (boil) and general furunculosis; therapeutic applications, by M. Loewenberg. He has observed a microbe in furuncle of the ear. These small abscesses spread in the ear by what he calls autocontagion, and from individual to individual contagiously. In treatment he employs thymic or boric acid. In cases of neglected otorrhea or wetness of the ear, especially with fetidity, he has always found micrococcus in large quantity.
