     Corrosive sublimate (Chem.), mercuric chloride, HgCl2; so
        called because obtained by sublimation, and because of its
        harsh irritating action on the body tissue. Usually it is
        in the form of a heavy, transparent, crystalline
        substance, easily soluble, and of an acrid, burning taste.
        It is a virulent poison, a powerful antiseptic, and an
        excellent antisyphilitic; called also mercuric  bichloride
        . It is to be carefully distinguished from
        calomel, the mild chloride of mercury.
