  Isomorphism \I`so*mor"phism\, n. [Cf. F. isomorphisme.]
     1. (Crystallog.) A similarity of crystalline form between
        substances of similar composition, as between the
        sulphates of barium (BaSO4) and strontium (SrSO4). It
        is sometimes extended to include similarity of form
        between substances of unlike composition, which is more
        properly called hom[oe]omorphism.
  
     2. (Math.) A one-to-one mapping of one set onto another set
        which preserves the relations between the elements of the
        domains of the sets.
