Spirit of Salt. Tonic and antiseptic; but principally used to dissolve calcareous concretions in the bladder. It has been used in the pestilent epidemics of cattle. Dose for a horse, 1 1/2 to 2 or 3 dr., in plenty of water, twice a day. Externally as a caustic, strongly recommended by Youatt.

Muriate Of Ammonia

Chloride of Ammonium, Sal Ammoniac, Hydrochlorate of Ammonia. Formerly used in influenza or epidemic catarrh. It is said also to have proved useful in farcy, and perhaps deserves trial in other chronic diseases. It renders the blood more fluid. Its use requires caution. 2 oz. produced inflammation of the mucous membrane of a horse; 2 dr. killed a dog, and 1/2 dr. a rabbit. M. Moiroud states the dose to be from 2 to 8 dr. for horses and cattle, and for small animals from a scruple to a drachm, largely diluted. Externally it is a frequent ingredient in discutient lotions to splints, old strains, bruises, indolent tumours, etc, in horses and cattle. It is also employed as an embrocation to sore teats.
