Spilleb, F.O.S. I have the pleasure of submitting to the notice of the Section several interesting results and improvements in photography, based, it may be said, on the chemistry of gelatin. The processes to which I refer are the various modifications of the Woodbury type, including the new method of micro-photo-sculpture, the art of photo-lithog- raphy, as practised in the Royal Arsenal at Woolwidi; and some illustrations of the use of gelatin or albumen, on a foundation of silk, satin, or ca...mbric, the work of H. P. Pritchard, of the War Department. The Hon. H. Fox Talbot was one of the first to describo and make a practical use of the action of light upon a mix- ture of gelatin and a soluble bichromate, and after him Colo- onel Sir Henry James, Mr. Swan, of Newcastle, and Mr. Woodbury, of Manchester, have applied the same chemical principle in new directions. It is known that the chemical rays of light have the effect of rendering insoluble gelatin to which a bichromate has been added.
