A Qua. Buxton water. See Aquae sulphureae. Buxton is in the Peak of Derbyshire. The waters there are the second in degree of heat among those of this island. The water of St. Anne's well is so pure, that when a gallon of the water was evaporated, the sediment was only fifteen grains; of which one grain and three quarters were sea salt, two and a half selenite, and ten and a half carbonate of lime rendered soluble by an excess of carbonic acid. The specific gravity of this water is precisely equal to that of rain water, when their temperatures are the same; but when first taken from the spring it is four grains in each pint lighter. The temperature of the bath is about eighty-two degrees.

The water of St. Anne's well contains about one sixty-fourth part of its bulk of azotic gas, in which its efficacy may in part reside, and which is quickly dissipated by exposure to the atmospheric air.

This water is alterative, and not evacuant; about a pint in the forenoon is at first taken, and the quantity gradually increased. The cooler the weather, the hotter and more medicinal is the water. It increases the vital heat, is useful in the gout, rheumatism, convulsive asthma, and other nervous complaints, indigestion, loss of appetite from intemperance, contractions of the tendons, urinary diseases, and defective cata-menia. Its temperature is the highest at which the cold bath has been used. See Bathing.

Besides the tepid mineral waters which are so much employed, there is a fine clear chalybeate water. Dr. Short evaporated a gallon of it; and a scruple of solid matter, above half of which he says was ochre, remained: the rest was a saline matter composed of sea salt and vitriolated magnesia. This water is drunk for the same purposes as other chalybeates.
