Uses, &c. Solution of acetate of ammonia is a very common and excellent febrifuge and

diaphoretic, and, in large doses, aperient saline liquor. Taken warm, in bed, it generally proves a powerful sudorific; and as it operates without heat, it is much used in febrile and inflammatory disorders. Its action may likewise be determined to the kidneys, by walking about in the cold air.—Dose, 2 to 6 dr., twice or thrice daily, either by itself or along with other medicines. Externally, as a discutient and refrigerant lotion; and diluted (1 oz. to 9 oz. of water), as a collyrium in chronic ophthalmia. For this last purpose it must be free from excess of ammonia.

5. (Concentrated.) Saturate acetic acid, sp. gr. 1·038, 12 gall., with carbonate of ammonia (in powder), 212 lbs., or q. s.; carefully avoiding excess.

Obs. This article is in great demand in the wholesale drug trade, under the name of ‘concentrated liquor of acetate of ammonia’ (LIQ. AMMON. ACET. CONC.). It is very convenient for dispensing. One fl. dr. added to 7 fl. dr. of water forms the LIQUOR AMMONIÆ ACETATIS of the Ph. L.
