There are many burning springs in different parts of the world, particularly one in France, in the department of Isere, near Grenoble; another near Her-manstadt, in Transylvania; a third at Chermay, a village near Switzerland; a fourth in the canton of Friburg; and a fifth not far from the city of Cracow, in Poland. There also is, or was, a famous spring of this kind at Wigan, in Lancashire, which, upon the approach of a lighted candle, would take fire and burn like spirit of wine for a whole day. But the most remarkable one in England, or at least that of which we have the minutest description, was discovered in 1711, at Brosely, in Shropshire. The following account of this remarkable spring was given by the Rev. Mr. Mason Woodwardin, Professor at Cambridge, dated Feb. 18th, 1746:-" The well, for four or five feet deep, is six or seven feet wide; within that, is another less hole of like depth, dug in the clay, in the bottom whereof is placed a cylindric earthen vessel, of about four or five inches diameter at the mouth, having the bottom taken off, and the sides well fixed in the clay, which is rammed close about it. Within the pot is a brown water, thick and puddly, continually forced up with a violent motion beyond that of boiling water, and a rumbling hollow noise, rising or falling by fits, five or six inches; but there was no appeaiance of any vapour rising, which perhaps might have been visible, had not the sun shone so bright. Upon putting a candle down at the end of a stick, at about a quarter of a yard distance, it took fire, darting and flashing after a very violent manner for about half a yard high, much in the manner of spirits in a lamp, but with great agitation. It was said, that a teakettle had been made to boil in nine minutes, and that it had been left burning for forty-eight hours without any sensible diminution. It was extinguished by putting a wet mop upon it; which must be kept there for a little time, otherwise it would not go out. Upon the removal of the mop, there arises a sulphureous smoke, lasting about a minute, and yet the water is very cold to the touch." In 1755, this well totally disappeared, by the sinking of a coal-pit in its neighbourhood. The cause of the inflammable property of such waters is with great probability supposed to be their mixture with petroleum, which is one of the most inflammable substances in nature, and has the property of burning on the surface of water.
