EpsoM water is that saline spring, which rises at the distance of about half a mile from the town of Epsom, in the county of Surrey. It is transparent, and colourless, at first almost insipid, but a snort time after it has been drunk, it leaves a bitter, saline taste on the tongue. It does not suffer any material alteration by being exposed to the air ; and, if closely corked in clean vessels, it may be preserved for several months in a fresh and potable state.
As this water contains only a small portion of the salt, namely, from one to two scruples, in the quantity of half a pint, the patient ought to drink from two to three pints successively, within a short space of time, in order to produce the full purgative effect If taken in this dose, it will operate in a mild and efficacious manner, but if in a smaller, its action is determined to the kidnies.

Those who 3re af-flided with hemorrhoidal and scorbutic complaints, will be benefited by the liberal use of this saline water, which likewise affords considerable relief in obstructions of the viscera.
