356 An Analyfn of two Mineral Springs 



nearly the whole of the fvilphat of lime was feparated. B? 

 adding fulphuric acid to this liquor, 20 grains of fulphat of 

 lime were precipitated. I concluded, therefore, that thii 

 mud have proceeded from the decompontion of muriat ol 

 lime : in truth, this fulphat was diifolved in the two ounce* 

 meafures of water, and was feparated by the decompofition 

 ©f the oxygenated fait. 



ON THE WATER OF THE OLD BATHS. 

 The fpring which fupplies thefe baths was difeovered m 

 1786, in which yiear a cold and a warm bath were con- 

 ilrufted. Upon linking the well, a rock was found at the 

 depth of eighteen feet ; and the water rifes from about the 

 depth of three feet within the rock. 



XV. THE GASEOUS FLUIDS. 



I could obtain very little gas from this water, not more 

 than three cubic inches from a gallon. It was azotic. An 

 hepatic fmell is perceptible when the water is frefli. To the 

 hepatic gas, doubtlefs, it is owing, that no oxygen is found 

 in this water or in that of the other fpring. Dr. Garnett 

 has fo well explained the caufe of this circumftance, that it is 

 needlefs for me to enter upon it. (See Dr. G. on the Mi- 

 neral Waters of Harrowgate, p. 74, &c.) 



XVI. THE SPONTANEOUS PRECIPITATE. 



This water is pellucid when it firft rifes from the fpring; 

 in fmall quantities it does not lofe its tranfparency : a very 

 fmall fediment is depofited by boiling, fo fmall indeed that 

 fufrieient cannot be collected in this way for examination. 

 However, when the bath has been newly filled, in fome hours 

 the tranfparency of this large body of water is dehroyed by ex- 

 pofure to the atmofphere, and it contracts a whitifh colour. I 

 collected a large quantity of this precipitate from the bottom of 

 the bath, where it by degrees accumulates. 1 . I nrft attempted 

 its analyfis by acids, but was difappointed. It is hardly foluble
