         the r'eaumur thermometer, is at the point at which
         water congeals. the zero of the fahrenheit thermometer
         is fixed at the point at which the mercury stands when
         immersed in a mixture of snow and common salt. in
         wedgwood's pyrometer, the zero corresponds with
         1077deg on the fahrenheit scale. see illust. of
         thermometer.

      the pointer of an indicating apparatus, or the needle of a
      galvanometer, remains at, or is brought to, zero, as
      contrasted with methods in which the deflection is
      observed directly; -- called also null method.
