Preparation.—"Musk, fifty grammes (50 Gm.) [1 oz. av., 334 grs.]; alcohol, four hundred and fifty cubic centimeters (450 Cc.) [15 fl℥, 104♏] water, four hundred and fifty cubic centimeters (450 Cc.) [15 fl℥, 104♏] diluted alcohol, a sufficient quantity to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]. Rub the musk in a mortar, first, with a little of the water, until a, smooth mixture is made, and then with the remainder of the water. Transfer the whole to a bottle, add the alcohol, and macerate the mixture for 7 days, occasionally shaking the bottle. Then filter through paper, adding, through the filter, enough diluted alcohol to make the tincture measure one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]"—(U. S. P.). This produces a pale-brown tincture, striking faintly opalescent with water. When made with a weaker alcohol, the odor is strong, the color deep red-brown, and, when mixed with water, the mixture remains transparent. A grain of musk is contained in 20 minims.
