SEIDLITZ WATER

The mineral water of Seidlitz, a village of Bohemia: sulphate of magnesia, sulphate of soda, and carbonic acid, are its active ingredients. It is often taken as an agreeable and effective aperient. The article sold under the name of Seidlitz powders is intended to produce the same effect, though very different in com-' position. These powders are generally sold in different coloured papers: one blue, containing 2 drachms of the pota a-tartrate of soda mixed with 2 scruples of bicarbonate of soda; the other red, containing 35 grains of finely powdered tartaric acid. The former powder is di olved in half a pint of water, and the latter in a separate wine-gla -full; the solutions are then mixed, and taken in the act of effervescence. [s. 1113]
