    tion begins in the serum at 150° to 170°, but weak solutions require a boiling heat, and merely become flaky or opalescent. Acetic acid, bibasic, and tribasic phosphoric acids, do not precipitate albumen. But tannic acid, alcohol, and creosote, as well as the mineral acids and most metallic salts, possess this power. Corrosive sublimate will detect l*2000th part of albumen in solution. Albumen is not only the solvent and vehicle for the earthy salts, but also the universal orga- nizable material which, in union with oil, may be converted into every living tissue. Fibrine exists as a solid in muscular fibre, and as a fluid in the liquor sanguinis. During coagulation it forms a delicate network, which is well seen in blood clot; and fibrine may be ob- tained by whipping coagulating blood with a bundle of twigs. Fibrine contains about 2 per cent, phosphates of lime and magnesia. Caseine exists chiefly in milk, but has been detected in the blood and pancreatic fluid. It is coagulated from its solution as well by the reagents that do as by the acids that do not coagulate albumen. It contains 6 per cent, of phosphate of lime and a little potash. # The Proteine compounds are distinguished from
