The next operation consists in diluting those pellicles, or rougher parts, which couldnot pass through the sieve, sifting them again, and using the white water resulting there-from to dilute the foul parts intended for subsequent operations. The sieve or sieves maysometimes happen to be obstructed by some parts of gluten adhering thereto, which I washoff with acidulated water for silk tissues, and with an alkali for metallic ones. This washingmethod I deem very important, as its non-application may hinder a rather large operation,and therefore I wish to secure it. This apparatus may be liable to some variations, and ad-mit of several sieves superposed, and with different tissues, the broadest, however, to beplaced uppermost. Among the various descriptions and combinations of sieves that may be employed, theannexed figures show one that will give satisfactory results:.
