USES.--It is best used in the official solution, but for dogs may be carried in tablets or pills containing ¹⁄₁₀₀ of a grain of glonoin. The spirit, however is more dependable. It is a good plan in cases of cardiac weakness to brace up the heart with Spirit of Glonoin, then maintain the effect with Tincture Strophanthus. SULPHUR SUBLIMATUM--SUBLIMED SULPHUR--FLOWERS OF SULPHUR DERIVATION.--Obtained from native sulphur by sublimation. PROPERTIES.--A fine, yellow powder, having a slightly characteristic odor and a faintly acid taste. Insoluble in water; slightly soluble in absolute alcohol; more readily soluble in benzine, benzol, oil of turpentine and many other oils; also in ether, chloroform and in boiling aqueous solutions of alkaline hydrates. DOSE.--Horses and cattle, 2 to 4 oz.; sheep and pigs, 1 to 2 oz.; dogs, 1 to 4 dr. PREPARATIONS SULPHUR LOTUM--WASHED SULPHUR DERIVATION.--Obtained from sublimed sulphur, which is treated with diluted ammonia water to wash out sulphurous and sulphuric and ether impurities. PROPERTIES.--A fine, yellow powder, without odor or taste. Solubility same as sublimed sulphur. DOSE.--Same as sublimed sulphur. SULPHUR PRECIPITATUM--PRECIPITATED SULPHUR DERIVATION.--Obtained from a solution of sublimed sulphur, 100; in boiling calcium hydrate, 50; by precipitation with hydrochloric acid. PROPERTIES.--A fine, amorphous powder, of a pale yellow color, without odor or taste. Solubility same as sublimed sulphur. DOSE.--Same as sublimed sulphur. UNGUENTUM SULPHURIS--SULPHUR OINTMENT Composed of washed sulphur, 150; benzoinated lard, 850. ACTIONS.--Sulphur applied to skin or mucous surfaces is a feeble, mechanical stimulant, and hence relieves chronic passive congestion. It destroys parasitic infestation of the skin. Administered internally it is a laxative and alterative. It destroys fungi on vines and kills similar parasites affecting plants and animals. How much of this toxic effect depends on the sulphur acting as sulphur, and how much on the alkaline sulphides, sulphuretted hydrogen and sulphurous acid into which it is gradually converted, has not been determined. Sulphur when swallowed is slowly acted upon by the alkaline secretions of the intestines, and small quantities are converted into sulphides, which stimulate the intestinal mucous membrane. A further change liberates sulphuretted hydrogen, which imparts its disagreeable smell to the breath, secretions of the skin and bowels. The greater part of the sulphur swallowed is removed unchanged by the bowels, but a portion is excreted in the urine as sulphates. Over-doses given to horses and other animals cause colic, purging, prostration and sometime fatal gastro-enteritis. USES.--Sulphur is given to the several domestic animals as a laxative where more powerful purgatives might irritate--as in pregnancy, convalescence from acute diseases in young animals, and in piles.
