                                                    Scott.

     3. (Biol.) An abrupt and marked variation in the condition or
        appearance of a species; a sudden modification which may
        give rise to new races.
        [1913 Webster]
  
              We greatly suspect that nature does make
              considerable jumps in the way of variation now and
              then, and that these saltations give rise to some of
              the gaps which appear to exist in the series of
              known forms.                          --Huxley.
        [1913 Webster]
