yield lib. of fait. So that fea-water is more than three times as ftrong as that of thefe fprings. A fait fpring has been [ (>5 ] lately difcovered at the Turkey foot on Yohogany, by which river it is overflowed, except at very low water. Its merit is not yet known. Dunning's lick is alfo as yet untried, but it is fuppofed to be the beft on this fide the Ohio. The fait fprings on the margin of the Onondago lake are faid to give a faline tafte to the waters of the lake.
There are feveral medicinal fprings, fome of which are indubitably efficacious, while others feem to owe their reputation as much to fancy and change of air and regimen, as to their real virtues. None of them having undergone a chemical analyfis in fkilful hands, nor been fo far the fubjed: of obfervations as to have produced a reduction into clafles of the diforders which they reUeve; it is in my power to give little more than an enu- meration of them.
The moft efficacious of thefe are two fprings in Augufla, near the firft fources of James river, where it is called JackK fon's river. They rife near the foot of the ridge of mountains, generally called the Warm fpring mountains, but in the maps Jackfon's mountains. The one is diftinguifhed by the name of the Warm fpring, and the other of the Hot fpring. The Warm fpring iflues with a very bold ftream, fuiRcient to work a grift mill, and to keep the waters of its bafon, which is 30 feet in diameter, at the vital warmth, viz. 96*^ of Farenheit's thermometer. The matter with which thefe waters is allied is very volatile; its fmell indicates it to be fulphureous, as alfo does the circumftance of its turning filver black. They relieve rheumatifms. Other complaints alfo of very different natures have been removed or leflened by them. It rains here four or five days in every week.
