Seltzer Water

Seltzer Water is a natural water which contains, together with certain quantities of mineral salts (eg. chloride of sodium and sulphate of magnesia), a large amount of dissolved carbonic acid gas, which gives it its sparkling properties. A water somewhat resembling the natural water may be prepared artificially by dissolving the salts in water and impregnating with carbonic acid gas under pressure, as in the various arrangements for the purpose sold under the names of seltzogenes, etc.
