Chap. 3.] Waters. 525 



e Couve and Beverfee. The Couve nearly referable* 

 the Tonnelet water ; or rather, may be placed in a 

 medium between that and the Watroz. It lordly 

 equals the tranfparency, fma/tnefs, and generous vi- 

 nous tafte of the firrl, but it greatly furpafies the latter. 

 The Beverfee agrees with this, only that it does not 

 retain its fmartnefs fo well by keeping. 



La Sige has fome of the general properties of 

 the Spa waters, but in other refpecls it is different. 

 It is moderately fubacid, fmart and grateful, but has 

 no fenfible chalybeate taile. It iparkles like Cham- 

 paign when poured from one glafs to another. Upon 

 ftanding it lofes its fixed air, and throws up a thick 

 mother-of-pearl coloured pellicle. It is much more 

 loaded with earthy matters, and lefs impregnated with 

 iron and fixed air, than the other Spa waters. 



Geromont. As a, chalybeate and acidulous water 

 this feems to be nearly of the fame itrength with La 

 Sige; but it contains a greater quantity of natron, to- 

 gether with a mixture of lea fait. The earthy mat- 

 ters, however, are lefs. 



It appears, that thefe waters are compounded of 

 nearly the fame principles, though in different propor- 

 tions. Ail of them abound with fixed air. They contain 

 more or lefs iron, alkali, and calcareous and felenitical 

 earths ; together with a fmall portion of fea fait. Thefe ' 

 are all kept fufpended, and in a neutral ftate, by means 

 of the aerial acid, or fixed air. From a review of the 

 contents of thefe waters, it cannot be imagined that their 

 virtues principally depend on the fmall quantity offolut 

 matters which they contain. They mud therefore de- 

 pend moftly on their Juced air. And they are probably 

 rendered more active and penetrating both in the firft 

 pafiage.s, and alfo when they enter the circulation by 



mean*
