Preparation.—"Euonymus, in No. 30 powder, one thousand grammes (1000 Gm, [2 lbs. av., 3 ozs., 120 grs.]; alcohol, water, each, a sufficient quantity. Mix six hundred cubic centimeters (600 Cc.) [20 fl℥, 138♏] of alcohol with 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 menstruum, using the same proportions of alcohol and water as before, until three thousand cubic centimeters (3000 Cc.) [101 fl℥, 212♏] of tincture are obtained or the euonymus is exhausted. Distill off the alcohol from the tincture by means of a water-bath, and having placed the residue in a porcelain capsule, evaporate it, on a water-bath, to a pilular consistence"—(U. S. P.).
