SELTZER water, is a mineral water which springs up at Lower Seltzer, a village in the electorate of Triers, about 10 miles from Frankfort on the Mayne, and 36 from Coblentz.

Seltzer water is brought to this country in stone bottles, which are closely corked and sealed, and contain about 3 pints each; and when they are well secured, it keeps unchanged for a considerable time.

Seltzer water, according to the analysis of Bergman, contains in an English wine pint,

grs. Carbonate of lime, 3 of magnesia, 5 of soda, 4 Muriate of soda, 17.5

29.5

The same quantity of water also yields 17 cubic inches of a gaseous substance, which is found to be almost entirely pure carbonic acid gas.

This water has been long in high repute, on account of its medical virtues, and we have no doubt that it may be used with considerable benefit in many of those complaints which arise from a deranged state of the stomach and bowels. The usual dose of this water is from half a pint to a pint; but in most cases it may be drunk freely. From its agreeable taste, and its exhilarating effects on the spirits, it is extensively employed at table as a common drink in Germany and Holland. In this country also, both the real and artificial Seltzer water is largely used for the same purpose. Seltzer water may be artificially imitated, by adding the ingredients diluted by analysis, and in the same proportion.
