      produces, intermittent motion.

   {Intermittent springs}, springs which flow at intervals, not
      apparently dependent upon rain or drought. They probably
      owe their intermittent action to their being connected
      with natural reservoirs in hills or mountains by passages
      having the form of a siphon, the water beginning to flow
      when it has accumulated so as to fill the upper part of
      the siphon, and ceasing when, by running through it, it
      has fallen below the orifice of the upper part of the
      siphon in the reservoir.
