Subchloride of Mercury

Horn quicksilver—subchloride of mercury, or native ealome]—is found associutsd with the other ores of quicksilver at Idria, at Deux-Ponts, in Spain, and elsewhere. It is a yellowish or ash-grey mineral, sectile, and suhtranslucent. Sometimes it occurs as a crust, or forms granular concretions,. At other times it crystallizes in four-sided prisms. Its specific gravity is 6-4S2, whilst that of the powdered calomel of the shops is 7T4, and that of the crystallized factitious subchloride is 7-2. 

Concentrated boiling solutions of the fixed alkaline chlorides, and of ohloride of ammonium, react upon calomel in the same way. Hot strong nitric acid readily dissolves the subchloride of mercury, converting it into a protonitrate and protoohloride of the metal, It is readily sublimed, and forms crystals on condensing. Its applications are chiefly medicinal, hut it is employed in the laboratory as a test, though not frequently so used. 

Any subchloride of mercury which may happen to he formed during the sublimation, owing to its not being so volatile as corrosive Sublimate, forms a whitish ring cn the lower part of the sublimed crust, and thus admits of being removed. Such portions may be added 4 E...

Probably no agent, whether of simple remedies or admitted poisons has ever received from the [allopathic] profession such universal and unqualified praise as cdomel—subchloride of mercury. Among many admirable qualities ascribed to it, is that of inducing freer action of the liver, and thus securing a more abundant flow of bile and more regular movements of the bow-...
