Magnesium Light. M. Silvy has sent to the Photographic Society of France some photographs, obtained by the aid of the magnesium light, of the vaults of the Chapel Royal of Dreux. These vaults, without being subterranean, are excessively dark, and only receive the daylight through painted windows placed at a considerable height, and very intense in colour; so that, without artificial illumination, it was impossible to take photographs of them. The lamp he used is so arranged as to burn at the same time four ribbons of magnesium passing through two parallel tubes, and the light produced by it is exceedingly beautiful. A great portion, however, of it is lost, or rather intercepted by the part of the ribbon which, having been burned, does not detach itself fast enough, and so obstructs the brilliancy of the flame, exactly as a candle which wants snuffing. It would be very easy, however, to obviate this inconvenience if, while waiting for some better contrivance, these primitive lamps were a little improved.
