![in boiling water and alcohol (90 per cent.). If an equal weight of sulphate of sodium and of this substance be dissolved in ten times their united weight of hot water, and set aside at 150 C., it forms sulphate of quinine. If dried at ioo° C., it loses 9 per cent, of water. .—As tonic : Cat 1 to 2 grains. Dog 1 to 5 „ Man and Pig - 1 to 10 ,, Sheep - 3 to 10 ,, Horse * 15 to 45 ,, Ox - 1 2 to i|- drachms.

Acid Hydrochloride of Quinine. Composition and Formula.—This is an acid hydrochloride of quinine, which is the alkaloid obtained from the bark of various species of cinchona and remijia. f-^20^-24^2^2 ’2 H C1,3 H20. Characteristics.—It is a white crystalline powder, soluble in less than its own weight of water, and the solution is slightly acid. Tests.—Those given by hydrochlorides are yielded, and there should be little or no sulphate reaction. One gramme dissolved in 20 c.c. of water should be completely neutralized by 2 5 c.c. of volumetric solution of soda. It can be transformed into sulphate of quinine by adding an equal weight of sulphate of sodium, and dissolving the mixture in ten times its weight of hot water, and then accurately neutralizing with solution of ammonia and setting aside to cool at 6o° F., when the usual tests for that substance will be yielded. If dried at 2120 F., it loses no more than 12 per cent, of water. Dose.— Man - - - - - - 1 to 10 grains. QUININE SULPHAS (A. and B.). Sulphate of Quinine. Formula.—[(C20H.24N2O2)2H2SO4]2,i5H2O. Mode of Preparation.—Sulphate of quinine is the sulphate of an alkaloid prepared from the powdered bark of various species 1 The use of quinine for this purpose is not to be advised as a rule, because there are several better antipyretic remedies.](https://iiif.wellcomecollection.org/image/b28062814_0382.jp2/full/800%2C/0/default.jpg)
