            The sounds water and fire, being once annexed to
            those two elements, it was certainly more natural to
            call beings participating of the first "watery", and
            the last "fiery", than to commute the terms, and
            call them by the reverse.             --J. Harris
      [1913 Webster]

            The utmost that could be obtained was that her
            sentence should be commuted from burning to
            beheading.                            --Macaulay.
