(1.) How it happens that rnofi of thefe waters 

 contain the above-mentioned minerals in a very 

 frnall quantity. 



(2.) How two fuch oppoiite matters, as a lix- 

 ivious fait and a vitriol can confift together, with- 

 out laying hold on each other. 



As to the firfb, we have often water in the 

 grooves, remarkably vitriolic ; but, fo far as my 

 knowledge of the fprings in Germany, England, 

 France, Hungary, &c. reaches, no fuch thing 

 can be affirmed of thofe at the day, feeing thefe 

 difcover only the leaf! vitriol, or other mineral 

 poflible : which, in fome meafure, we may ac- 

 count for from fuch waters taking their rife nearer 

 the day, when the more day-water coming to mix 

 with them, they thus become weakened and di- 

 luted. 



But then, that mineral fprings mould remain of 

 one contlant yield, and become neither richer in 

 hot, dry, fummer- weather, nor remarkably {mailer 

 or poorer in the moifteft harvefts and fprings, 

 we mud afcribe to fuch waters having a diftan f :, 

 deep, and not a near origin, not only in refpecl: of 

 their mineral particles, but alfo their univerfal 

 watrinefs ; likewife, to fuch pyrites as vitriolifi 

 fparingly and leifurely : not toinfift on their great 

 plenty \ as there are fprings that have continued 

 running for a long courfe of years \ which mews 

 the (lock they are derived from to be inexhauf- 

 tible. 



Hence we exclude all pyrit*, vitriolifing fo ea- 

 .. - fo richly and fo quickly, as the round in gc~
