root and seeds, 2; prepared coral, 1; elk’s hoof, 2; seeds of orache, 2. Given in doses of a few grains in convulsions of infants, or in larger doses for epilepsy.
Powder, Antihydrophobic. (Dr Mead.) Syn. Pulvis antilyssus. Prep. Ash-coloured ground liver-wort (Pettidea canina), 1⁄2 oz.; black pepper, 2 dr.; mix, and give a fourth part every morning for 4 times.
Powder, Antimo′′nial. Syn. Fever powder, Lisle’s p., James’s p.; Pulvis Jacobi, Pulvis antimonialis (B. P., Ph. E., & D.), Pulvis antimonii compositus (Ph. L.), L. Prep. 1. (Ph. L.) A mixture of tersulphide of antimony, 1 lb., and hartshorn shavings, 2 lbs., is reduced to powder, thrown into a crucible heated to whiteness, and stirred constantly until vapour no longer rises; the calcined mixture is then rubbed to powder, again put into the crucible, and the heat gradually increased to whiteness, and maintained so for 2 hours; the residuum is, lastly, reduced to a very fine powder.
2. (Ph. E.) From sulphide of antimony and hartshorn shavings, equal weights; as the last.
3. (Ph. D.) Tartarised antimony, 4 oz., is dissolved in water, 1⁄2 gall., and added to solution of phosphate of soda, 4 oz., in water, 1 quart; a solution of chloride of calcium, 2 oz., in water, 1 quart, and to which solution of ammonia (Ph. D.), 4 fl. oz., has been added, is next poured in, and the whole boiled for 20 minutes; the precipitate is then collected on a calico filter, and washed with hot distilled water, until the liquid which passes ceases to give a precipitate with a weak solution of nitrate of silver; it is, lastly, dried by a steam or water heat, and reduced to a fine powder.
4. (B. P.) Oxide of antimony, 1; precipitated phosphate of lime, 2; mix.—Dose, 2 to 6 gr.
Uses, &c. Febrifuge and diaphoretic. Intended as a substitute for the proprietary and more expensive James’s powder.—Dose, 3 to 10 or 12 gr., or more, repeated every fourth or fifth hour until diaphoresis is set up; in fevers, rheumatic affections, chronic skin diseases, &c. It is a very uncertain and variable compound, unless it has been carefully prepared. Dr Elliotson exhibited it in doses of 100 gr. without producing any sensible effect. A spurious article, made by triturating 1 oz. of tartar emetic with 18 or 19 oz. of burnt hartshorn, is frequently sold for it in the shops. See Antimonious acid and James’s powder.
