      called because obtained by sublimation, and because of its

      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

      calomel, the mild chloride of mercury.
