Far better it is to wash it in the way I shall now describe.
WAsrimG.
The lump of emulsion which is the result of setting, con- tains not only the sensitive and insoluble bromide of silver, but also the insensitive and soluble nitrate and bromides. These must be removed. It can be done by washing.
Gelatine holds these soluble salts very tightly in its grasp, and to remove them thoroughly it is necessary to break the jelly up into small pieces so that the water may penetrate them and dissolve th...e salts.
There are several ways of subdividing the gelatine, but the simplest and best is to squeeze the jelly through the meshes of embroidery canvas. Procure a piece of canvas known as "railway canvas, " about eighteen inches square. Yon can buy it at a shop dealing in worsteds, etc. Yon must first thoronghly soak it in boiling water to remove the size and starch ; then dry it again. I have two common water jugs with mouths wide enough to admit my two hands. They hold a gallon of water each. I have also a hair sieve seven inches in diameter, the use of which I shall explain further on.
