A process of photoengrav-ing and printing, invented by Mr. Walter Woodbury. A plate, coated on one side with a solution of bichromate of potash or bichromate of ammonia, in gelatine, is exposed, in contact with a negative, to the light, which, passing through the unshaded portions of the negative, renders certain portions of the gelatinous film insoluble, while the other parts remain more or less soluble, in proportion to the intensity of shade in the negative. The plate is then placed in a bath of warm water, and the soluble portions of the gelatine r<
