The _Hot spring_ is about six miles from the Warm, is much smaller, and has been so hot as to have boiled an egg. Some believe its degree of heat to be lessened. It raises the mercury in Fahrenheit's thermometer to 112 degrees, which is fever heat. It sometimes relieves where the Warm fails. A fountain of common water, issuing within a few inches of its margin, gives it a singular appearance. Comparing the temperature of these with that of the Hot springs of Kamschatka, of which Krachininnikow gives an account, the difference is very great, the latter raising the mercury to 200° which is within 12° of boiling water. These springs are very much resorted to in spite of a total want of accommodation for the sick. Their waters are strongest in the hottest months, which occasions their being visited in July and August principally. The Sweet springs are in the county of Botetourt, at the eastern foot of the Alleghany, about forty-two miles from the Warm springs. They are still less known. Having been found to relieve cases in which the others had been ineffectually tried, it is probable their composition is different. They are different also in their temperature, being as cold as common water; which is not mentioned, however, as a proof of a distinct impregnation. This is among the first sources of James' river. On Potomac river, in Berkley county, above the North mountain, are medicinal springs, much more frequented than those of Augusta. Their powers, however, are less, the waters weakly mineralized, and scarcely warm. They are more visited, because situated in a fertile, plentiful, and populous country, better provided with accommodations, always safe from the Indians, and nearest to the more populous States. In Louisa county, on the head waters of the South Ann branch of York river, are springs of some medicinal virtue. They are not much used however. There is a weak chalybeate at Richmond; and many others in various parts of the country, which are of too little worth, or too little note, to be enumerated after those before mentioned. We are told of a sulphur spring on Howard's creek of Greenbriar, and another at Boonsborough on Kentucky.
