Preparation.—"Take of hydrochlorate of morphine, 20 grains; tincture of tolu, 1/2 fluid ounce; refined sugar, in powder, 24 ounces (av.); gum acacia, in powder 1 ounce (av.); mucilage of gum acacia, a sufficiency; distilled water, 1/2 fluid ounce. Dissolve the hydrochlorate of morphine in the water; add this solution to the tincture of tolu, previously mixed with 2 fluid ounces of the mucilage; then add the gum and sugar, previously mixed, and more mucilage, if necessary, to form a proper mass. Divide into 720 lozenges, and dry these in a hot-air chamber at a moderate temperature. Each lozenge contains 1/36 grain of hydrochlorate of morphine"—(Br. Pharm., 1885). The present British Pharmacopoeia (1898) directs Trochiscus Morphinae of the same strength; it is made by incorporating morphine hydrochloride with the tolu basis.
