Preparation.—"Rhubarb, in No. 30 powder, one hundred grammes (100 Gm). [3 ozs. av., 231 grs.]; calamus, in No. 30 powder, ten grammes (10 Gm.) [154 grs.]; stronger white wine (F. 440), a sufficient quantity to make one thousand grammes (1000 Gm.) [2 lbs. av., 3 ozs., 120 grs.]. Moisten the mixed powders with fifty grammes (50 Gm.) [1 oz. av., 334 grs.] of stronger white wine, pack the mixture in a conical glass percolator, and gradually pour enough stronger white wine upon it to make the filtered liquid weigh one thousand grammes (1000 Gm.) [2 lbs. av., 3 ozs., 120 grs.]"—(Nat. Form.). This is based on the U. S. P. (1880) formula.
