This, the chloride of mercury, is a deadly poison; three or four grains of it may kill a man. Symptoms of its action are, in a marked degree, those of the irritant poisons; a metallic taste, burning in the mouth, throat, and stomach, pain in the abdomen, vomiting, purging, with straining, nervous anxiety, extreme prostration; often convulsions, sometimes stupor, before death. Commonly, death does not result under one or more days ; but examples are recorded of its taking place within an hour after the poison had been swallowed. Treatment of corrosive sublimate poisoning requires (as for copper) free administration of whites of eggs ; the more the better, until relief is obtained; or, if eggs cannot be had, large and repeated draughts of milk.
