(Ought to be called extract of aconite root, being several times the strength of the Extract of Aconite of 1870, which was made from the leaves). The official process for its preparation is as follows : To make the ex- tract from five hundred grams (17f avoirdupois ounces) of the drug in No. 60 powder : Moisten with a solution of five grams (77 grains) tartaric acid in two hundred grams (8|- fluidounces) alcohol. Pack tightly in a cylindrical percolator. Saturate with menstruum. Macerate twenty-four hours. Percolate. Reserve four hundred and fifty grams (about 15 fluid- ounces) of first percolate. Continue percolation until the aconite is ex- hausted, or until 1,050 grams (about 42 fluidounces) second percolate has been collected. Evaporate the second percolate to fifty grams (If ounce) before adding it to \\v% first percolate. Evaporate the mixture to a pilular consistence. To the remainder add one-twentieth part of its weight of glycerin. Practically the same product is obtained by evaporating the fluid extract to the pilular consistence and then incorporating the five per cent, of glycerin. It is dark brown. Dose.—0.005 to 0.015 gram (Jg to |- grain). Caution.—Be careful in dispensing extract of aconite to deter- mine whether the extract of the root ( Extract of Aconite, U. S. Pharmacopoeia, 1880), or the extract of the leaf ( Extract of Aconite, U. S. Pharflaacopoeia, 1870), or the extract of the fresh leaves and flower- ing tops (Extract of Aconite, B. P.), is intended, and whether the dose is a safe one, as these several extracts of aconite vary greatly in strength, while they all have the same name and are in actual use, and generally found in the shops, with the exception of the official extract of the new Pharmacopoeia of the United States, which is not yet in com- mon use. The new extract of aconite (from the root) is at least four times the strength of the extract of aconite of the old U. S. Pharmacopoeia, which is now in stock in all drug stores, and at least twice the strength of the English Extract of Aconite, which is used a great deal in this coun- try (Allen's). Physicians prescribing extract of aconite ought to designate which
