Hemoglobin \Hem"o*glo"bin\, n. [Hemo- + globe.] (Physiol.)
   The normal coloring matter of the red blood corpuscles of
   vertebrate animals. It is composed of hematin and globulin,
   and is also called h[ae]matoglobulin. In arterial blood, it
   is always combined with oxygen, and is then called
   oxyhemoglobin. It crystallizes under different forms from
   different animals, and when crystallized, is called
   h[ae]matocrystallin. See Blood crystal, under Blood.
