But for that purpose it would have been necessary to take the photographs of the objects in motion, which at that date would have been impossible, except at the lowest velocities. The same article figures an apparatus devised in America about 1861 by Coleman Sellers. It was called a "stereophantascope," and was intended to obtain the same result as Reville. The most remarkable conception was, by all odds, that of M. Ducos du Hauron, who in March, 1864, took out a patent for <m apparatus for photographing any scene with all the transformations which it might go through in given lime. How to take the photo-.
