e %'onndst. This is one of the moft fprightly wa- 

 ters in the world. It is much colder than either of 

 the other Spa waters ; has no fmell ; is bright, tranf- 

 {arent, and colourlefs ; and from the rapidity of its 

 motion does not foul its bafon. It has a fmart, fub- 

 , fprightly taile, not unlike the brifkeft Cham- 

 iv.ign wine. 1'rorn a number of experiments it appears, 

 that this water is more flrongly charged than- any of 

 the others with fixed air, on which the energy of all 

 waters of this kind principally depends, but it parts 

 with it more readily. It contains more iron than any 

 of the fprings, except the Pouhon. 



' Watrbz. fits fituation is loweil of any of the? 

 fprings about Spa, and it is more apt to be foul : buc 

 when the well is cleaned out, and the water pure, it is 

 found to be of the lame nature as that of Pouhon. It

 than the Pouhon. It has a fulphureous fmell at the 

 fountain, which it lofes by being carried to a diftance. 

 This fmell is ftrongeft in warm moift weather. The 

 air, or vapour, of this water affects the heads of fome 

 who drink it, occafioning a giddinefs or kind of intox- 

 ication, which goes off in a quarter or half an hour. 

 The Pyrmont, and feveral other brifk chalybeate wa- 

 ters, are found to have the fame effect. It is colder 

 than any of the fprings, the Tonnelet excepted. 



* SartS) or Niverfet. It refembles the Tonnelet 

 water, but is rather lefs briik and gafeous. It is how- 

 f ver more acid and ftyptic. 



' Bru or Chevron. The phyficians at Liege have 

 artfully decried this water, becaufe it is n6t in the 

 principality of Liege. But by every trial it appears 

 not much inferior to any of the Spa waters. In the 

 quantity of fixed air and of iron it contains, it ap- 

 proaches the Pouhon,
