An aqueous solution of ammonium acetate containing about seven per cent of the salt, together with small amounts of acetic acid and carbon dioxide. DERIVATION.--Ammonium carbonate is gradually added to cold, dilute acetic acid until the latter is materialized. PROPERTIES.--A clear, colorless liquid, mildly saline and acidulous taste, and an acid reaction. Incompatible with acids and alkalies. DOSE.--Horses and cattle, 2 to 4 oz.; sheep and pigs, ¹⁄₂ to 1 oz.; dogs, 2 to 6 drs. ACTIONS.--Diaphoretic, antipyretic, mild stimulant, mild diuretic, mild expectorant and stomachic. USES.--Its uses are recommended in febrile and inflammatory attacks, especially in influenza, distemper, etc., combined with other medicines, improves the appetite; can be used externally as a refrigerant over swollen and inflamed tendons. AMMONII CARBONAS--AMMONIUM CARBONATE DERIVATION.--A mixture of ammonium chloride or sulphate, and calcium carbonate, is sublimed and resublimed. Ammonium carbonate, so-called, is a mixture of ammonium carbonate and bicarbonate. PROPERTIES.--White translucent masses, having a strongly ammoniacal odor, and a sharp saline taste. On exposure to air it loses both ammonia and carbonic dioxide, soluble one part in four parts of water. DOSES.--Horses and cattle, 1 to 3 drs.; sheep and pigs, ¹⁄₄ to 1 dr.; dogs, 2 to 8 grs. Larger doses are recommended when a antispasmodic or carminative is desired the dose for horses and cattle can be increased to an ounce, but only two doses should be administered, well diluted in water or in ball or capsule. ACTIONS.--Ammonium carbonate is decomposed by acid in the stomach and escapes in the urine. It stimulates gastric secretion, vascularity and motion, and exciting intestinal peristalsis. It is, therefore, a stomachic and carminative. It is also an antacid, and, in large doses, an emetic for dogs. It is given in capsules or in solution in cold water, to avoid irritating fumes; also with syrup or gruel. It is often prescribed with other stimulants and antispasmodics, as alcohol, camphor, capsicum and asafoetida. The action of ammonium carbonate is almost identical with that of ammonia water in stimulating the heart and respiration, but it has more power in augmenting the bronchial secretions.
