   {Malignant pustule} (Med.), a very contagious disease
      produced by infection of subcutaneous tissues with the
      bacterium {Bacillus anthracis}. It is transmitted to man
      from animals and is characterized by the formation, at the
      point of reception of the infection, of a vesicle or
      pustule which first enlarges and then breaks down into an
      unhealthy ulcer. It is marked by profound exhaustion and
      often fatal. The disease in animals is called {charbon};
      in man it is called {cutaneous anthrax}, and formerly was
      sometimes called simply {anthrax}.
      [1913 Webster +PJC]

   coal, carbuncle.]

      anthracis}), resembling transparent rods. [See Illust.
      under {Bacillus}.]
      [1913 Webster]

   3. An infectious disease of cattle and sheep. It is ascribed
      to the presence of a rod-shaped gram-positive bacterium
      ({Bacillus anthracis}), the spores of which constitute the
      contagious matter. It may be transmitted to man by
      inoculation. The spleen becomes greatly enlarged and
      filled with bacteria. Called also {splenic fever}.

      East Indies. When held up to the sun, it loses its deep
      tinge, and becomes of the color of burning coal. The name
      belongs for the most part to ruby sapphire, though it has
      been also given to red spinel and garnet.
      [1913 Webster]

   2. (Med.) A very painful acute local inflammation of the
      subcutaneous tissue, esp. of the trunk or back of the
      neck, characterized by brawny hardness of the affected
      parts, sloughing of the skin and deeper tissues, and
      marked constitutional depression. It differs from a boil
      in size, tendency to spread, and the absence of a central
      core, and is frequently fatal. It is also called
      {anthrax}.
      [1913 Webster]

   3. (Her.) A charge or bearing supposed to represent the
      precious stone. It has eight scepters or staves radiating
