![Test.—The salt imparts a yellow colour to flame. Therapeutics.—Sulphate of sodium has a similar action as a purgative to that of sulphate of magnesium. Being less reliable than the latter salt, it is not much used, excepting as a cathartic for cattle. It has also alterative and diuretic properties. In the dog it causes emesis as well as catharsis, but it is seldom or never employed for this animal. Dose.—Man - - - 30 to ] 20 grains, but for one Formula.—Na2S03,7H20. Mode of Preparation.—Sulphite of sodium is obtained by the action of sulphurous acid on carbonate of sodium or on hydroxide of sodium. Characters.—Sulphite of sodium exists in colourless, trans- parent, monoclinic prisms. It effloresces in dry air, is inodorous, and has a cooling, saline, and sulphurous taste. The salt is readily soluble in water, and very sparingly in alcohol. An aqueous solution has a neutral or faintly alkaline reaction, imparts an intense yellow colour to flame, and if treated with hydrochloric acid evolves sulphurous oxide gas, but does not become cloudy (proving that a thiosulphate is not present). One gramme in 50 c.c. of water decolourizes about 797 c.c. volumetric solution of iodine. Therapeutics.—Sulphite of sodium is antiseptic and deodorant. It evolves sulphurous acid on addition of hydrochloric acid to the aqueous solution, and also when ingested into the stomach. It has been very extensively administered in veterinary practice in septic diseases, such as the specific fevers, as influenza, scarlet fever, strangles, purpura, and anthrax of horses ; pleuro-pneu- monia, cattle - plague, foot-and-mouth disease, and anthrax of cattle ; in foot-and-mouth disease and anthrax of sheep ; in swine fever; and in pyaemia and septicaemia of various animals. Although this salt has been so extensively given, there is still a difference of opinion regarding its value in septic diseases. It Dog Sheep Horse Ox - administration \ to \ ounce.
