$solutions of corrosive sublimate, and many other metallic salts, by nitric, sulphuric, hydrochloric, and tannic acids, and by heating over 180°. It is not precipitated by acetic acid, thus differing from casein. Vitellus Ovi. Yolk of egg consists of a mixture of albumen and casein (Vitelline), and a yellow oil containing phosphoric acid.

Test for Tannic acid. Nutritive. Affords an easily assimi- lated fat. Beneficial in struma, phthisis, defective nutrition, Isinglass. The swimming-bladder or sound of various species of sturgeon, prepared, cut into shreds, and dried. It consists almost entirely of pure gelatine (9 per cent.); it is soluble in warm water, but gelatinises on cooling; insoluble in alcohol and ether. From its aqueous solution gelatine is precipitated by alcohol, corrosive sub- limate, perchloride of platinum, and by tannic acid—the latter forming leather. A solution of gelatine in water is not, like one of albumen, coagulated by heat. By prolonged boiling the gela- tinous power on cooling is destroyed. Oleum MorrhuaB. Is prepared from the fresh liver of the cod by the application of a heat not exceeding 180°. It contains glycerine, oleic, marfraric, butyric, and acetic acids, a peculiar substance called gaduin, various biliary principles due to the hepatic source of the oil, iodine in small quantities, traces of bromine, chlorine, phosphorus, and salts A volatile alkaloid, P^^^^^ (NH^CgH^), can be obtained by distilling the oil with alkalies. It is stated that the fats of this oil are not true glycerides, but are salts of Propyl (QMX and yield Pmpyl hydrate (C3H7HO) on saponification instead of fflv- cerme (Muter). The best ( pale) oil is of a pale-yellow colour$
