The watering-place of Kissingen is situated in north latitude 49° 50′ east longitude, 9° 50′ from Greenwich, 60 English miles east of Frankfort. Long before it was frequented for medical purposes, its salt springs were turned to profitable account. Of these there are several, but the one recently enlarged by boring, known under the name of the Runde Brunnen, is much more remarkable than the others, on account of its Copiousness, its Temperature, its discharge of Carbonic Acid Gas in vast quantity, and its extraordinary phenomenon of Intermission.
