Preparation.—"Aspidosperma, in No. 60 powder, one thousand grammes (1000 Gm.) [2 lbs. av., 3 ozs., 120 grs.]; glycerin, one hundred cubic centimeters (100 Cc.) [3 fl℥, 183♏]; alcohol, water, each, a sufficient quantity to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]. Mix the glycerin with six hundred cubic centimeters (600 Cc.) [20 fl℥, 138♏] of alcohol and three hundred cubic centimeters (300 Cc.) [10 fl℥, 69♏] of water, and, having moistened the powder with four hundred cubic centimeters (400 Cc.) [13 fl℥, 252♏] of the mixture, pack it firmly in a cylindrical percolator; then add enough menstruum to saturate the powder and leave a stratum above it, When the liquid begins to drop from the percolator, close the lower orifice, and, having closely covered the percolator, macerate for 48 hours. Then allow the percolation to proceed, gradually adding, first, the remainder of the menstruum, and then a mixture of alcohol and water, made in the proportion of two hundred cubic centimeters (200 Cc.) [6 fl℥, 366♏], of alcohol to one hundred cubic centimeters (100 Cc.) [3 fl℥, 183♏] of water, until the aspidosperma is exhausted. Reserve the first eight hundred cubic centimeters (800 Cc.) [27 fl℥, 25♏] of the percolate, and evaporate the remainder at a temperature not exceeding 50° C. (122° F.) to a soft extract; dissolve this in the reserved portion, and add enough menstruum to make the fluid extract measure one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]"—(U. S. P.).
