Synonym. - Carburetum Sulphuris.

Present name. - Carbonic Sulphide.

Bisulphuret of Carbon.

Prepared by passing the vapour of Sulphur over Charcoal, heated to redness in a porcelain tube, and condensing the product in a properly cooled vessel. It is then purified by re-distillation over quicklime.

Characters. - A very volatile, colourless liquid, of high refracting power, of an acrid, pungent taste, and a fetid, peculiar, sulphurous odour. Insoluble in water; soluble in all proportions in ether, and in alcohol. Its vapour is very poisonous, and great care should be taken to secure it in well-stoppered bottles.
