Sulphate of soda, a well-known cathartic. It is a white
crystalline substance, with a cooling, slightly bitter taste,
and is commonly called ``salts.''
Note: It occurs naturally and abundantly in some mineral
      springs, and in many salt deposits, as the mineral
      mirabilite. It is manufactured in large quantities as
      an intermediate step in the ``soda process,'' and also
      for use in glass making.
