Seidlitz

or Sedlitz, (WATERS OF,) a mineral water, obtained from a village of that name in Bohemia. The waters are saline and purgative, limpid, sparkling, and of a bitter and salt taste; being composed principally of the sulphates of magnesia and lime and carbonic acid. They are employed as purgatives in a multitude of diseases.- S.powders are intended to produce a similar effect, though their composition is different. They are generally sold in blue and white papers; a blue paper contains two drachms of tartrate of soda, with two scruples of bicarbonate of soda; the white paper thirty-five grains of finely powdered tartaric acid. The contents of the former are to be di olved in half a pint of water, that of the latter in a separate winegla ful; the solutions are to be mixed, and the mixture taken while effervescing. [s. 811]
