Description:Excerpt from The American Journal of Pharmacy, Vol. 17: January, 1851 Oil of Laurel has a light amber color, a penetrating persis tent and peculiar odor, and an aromatic, somewhat bitter, and not very pungent taste, which perhaps may be called slightly camphor ous. There is nothing in the taste or smell that reminds one of copaiba. Its specific gravity is 898. Distilled carefully per se, nearly the whole passes over as a very limpid colorless volatile oil, leaving a small quantity of soft, dark-brown, transparent resin in the retort. The odor of the oil is different, but analogous to that of the oleo-resin itself. When freshly obtained its smell is sufh ciently like that emitted by good socotrine aloes, when breathed upon, to call it to mind. Its taste is like that of the native pro duct. This volatile oil is soluble in all proportion in alcohol 798, and in ether, and requires but five times its bulk of alcohol 838 for solution. It mixes readily with other volatile oils 'with fixed oil, and chloroform, and is soluble in acetone, and pyroxilic spirit. It dissolves more than its bulk of camphor with the assistance of heat, and becomes a soft crystalline solid by cooling. It dissolves resinous bodies with facility, and its ready volatility would render it a suitable Inenstruum for varnishes. A hot concentrated solution of caustic potassa has no action on it; when a globule of bright potas sium is put into a small quantity ofthe colorless oil, it has no imme diate action on it, but by standing the metal becomes surrounded by a dark-brown, transparent, resinous mass, evidently indicating the presence of oxygen in the oil. This reaction, together with its ready solubility in alcohol 838, will readily distinguish the oil from recent oil of copaiba which is unaffected by potassium, and is but slightly soluble in alcohol of the sp. Gr. Indicated. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
