high, and confift either of earth, or of 

 iock-ftone. 



One of thefe brooks, which flows over 

 a hill of lime-flone, contains a mineral wa- 

 ter. It has a flrong fmell of fulphur, is 

 Very clear, and does not change its colour, 

 when mixed with gall-appIcs. If it is 

 poured into a lilver cup, it looks as if the 

 cup was gilt ; and the water leaves a fedi- 

 ment of a crimfon colour at the bottom. 

 The flones and pieces of wood, which ly 

 in the water, are covered with a flimej 

 which is pale grey at the top, and black at 

 the bottom of the fione. This ilime has 

 not much pungency, but tafles like oil of 

 tobacco. My hands had a fulphureous 

 fmell all day, becaufe I had handled fome 

 of the flimy ftones. 



The black lime-flate now abounds agaiPi 

 near the level of the water. It lies in 

 flrata, which are placed almoft perpendi- 

 cularly near each other, inclining a little 

 towards W. S. W. Each ftratum is be- 

 tween ten and fifteen inches thick. Moft 

 of them are fliivered into thin leaves at the 

 top, towards the day ; but in the inGde, 

 whither neither fun^ nor air and water can 

 penetrat^^ they are clofe and compact. 

 Some of thefe ftones are not quite black, 

 but have a greyifh caft.
