At a recent meeting of the New York Society of Amateur Photographers, Newton called attention to the danger of the injurious action of soda hyposulphite, contained in the dividing paper frames, upon gelatine plates as they are at present put up and sold. He exhibited several specimens in which the deleterious action of the chemical was distinctly visible. The general effect was to fog the edge, and frequently the whole of the plate, and thus seriously injure it for future use. As a remedy, he suggested that the plates be packed in tin or metal boxes, or that the division frames be varnished or shellacked, which would in a measure counteract any injurious effect of the chemicals contained in the paper.
