     1. The act of cleaving or splitting.
        [1913 Webster]
  
     2. (Crystallog.) The quality possessed by many crystallized
        substances of splitting readily in one or more definite
        directions, in which the cohesive attraction is a minimum,
        affording more or less smooth surfaces; the direction of
        the dividing plane; a fragment obtained by cleaving, as of
        a diamond. See Parting.
        [1913 Webster]
  
     3. (Geol.) Division into lamin[ae], like slate, with the
