Abstract
PARIS
Academie des Sciences, Sept. 11.—M. Faye in the chair, —M. Dumas read an abstract of a pamphlet published by MM. Lomer and Ellershausen, advocating the establishment at Belle-garde, in the department of Ain, of hydraulic machines worked by the Rhone, and giving a force of 10,000 horse-power. The site is called “Le perte du Rhone”at Bellegarde, and this immense hydraulic pressure is to be obtained by boring a tunnel through which only one-third of the water of the Rhone will go. The height of the fall will be sixty feet, and the result is to be obtained very easily, as the tunnel is only to have a length of 550 yards. The engineers hope to create at Bellegarde a city as important as Lowell in the United States. It is intended to induce Alsatian manufacturers to move from Mulhaus, and to settle in that locality.— M. Decaisne sent some observations relating to animals fed with bread infested with the oidium aurantiacum, and it is considered as demonstrated that, at least under special circumstances, such food must be considered as being really poisonous. —M. Berthelot sent a very long paper on the union of alcohol with bases, which was inserted in extenso in the Comptes Rendus. —M. Lecoq de Boisbaudron sent also a paper which was published by him some time ago, on the constitution of luminous spectra. —M. Favre sent a paper to elucidate certain points of a special theory worked out to explain how a certain weight of copper rotating between the poles of an electro-magnet is heated by the influence at a distance. The fact was discovered by Foucault.
