    was obtained by Tarozzi by decomposing sulphate of quinine by albuminate of soda. It is not decomposed by alkalies, and is said not to decompose in the system like the other salts of quinine. Quininse Hydrobromas (U.S.P.)—In colourless lustrous needles. 4 grs. dissolve in i dr. of water for hypodermic injection, which may be repeated every four hours without causing irritation. The Acid hydrobromate of quinine (yellow crystals) is more soluble than the above, which is neutral, i dr. of water will dissolve 10 grs. of it. Where quinine cannot be given by the mouth this salt can be readily employed hypodermically. A very much smaller dose is necessary when injected into the sub- cutaneous tissue. It produces, whether taken by the mouth or injected, less unpleasant symptoms than the other quinine salts. QuinillSB Lactas has recently been shown by Vigier to be a salt very suitable for hypodermic administration in aqueous solution (i in 8). Quillilise Salicylas—This salt meets a want which the physician frequently experiences when he wishes to combine quinine with salicylic acid or its salts in chronic or subacute rheumatism, or in neuralgia occurring in rheumatic patients. The method of prescribing salicylic acid in a mixture with quinine often leads to the formation of an incompatible mess, which accumulates in the mixture and adheres like wax to the sides of the phial. Salicylate of quinine exists as white silky needles very sparingly soluble in water ; it is best prescribed in the form of pills, 4 grs. each made up with Proctor's paste. Quininae Sulphocarbolas is a white powder prepared by mixing hot solutions of sulphate of quinine and carbolic acid, and may be given in pill in doses of 2 to 8 grs. QuininSB Tannas is a salt of quinine existing as a white, almost tasteless, amorphous, insoluble powder prepared by de- composing sulphate of quinine solution with strong solution of tannic acid. It is recommended for children. Its dose cor- responds to that of the sulphate. Quininae Valerianas (U.S.?.)—In white lustrous crystals, smelling slightly of valerianic acid. In addition to the valuable properties of quinine, this salt possesses superior power over neuralgia in hysterical patients. The dose should not exceed 3 grs., and should be given in pill. Quininse et Ureae Hydrochloras is a very soluble quinine salt, which is the best form for giving the drug hypo- dermically ; it contains over 60 per cent, quinine. It may be
