though, in this ftate, it may arTecl: the tafte more 

 fenfibly, it cannot be of fo much ufe in the ftomach 

 and bowels, as when the air is more firmly retained 

 by the water, though, in confequence of it, it be 

 lefs feniibie to the tafte. 



By the procefs defcribed in my pamphlet, fixed 

 air may be readily incorporated with wine, beer, and 

 almoit any other liquor whatever; and when beer* 

 wine, or cyder, is become flat or dead (which is the 

 confequence of the efcape of the fixed air they con- 

 tained) they may be revived by this means ; but the 

 delicate and agreeable flavour, or acidulous tafte,. 

 communicated by fixed air, and which is very mani- 

 feft in water, can hardly be perceived in wine, or 

 any liquors which have much tafte of their own. 



I fhould think that there can be no doubt, but 

 that water thus impregnated with fixed air muft have 

 .all the medicinal virtues of genuine Pyrmont water ; 

 fince thefe depend upon the fixed air it contains. If 

 the genuine Pyrmont water derives any advantage 

 from its being a natural chalybeate, this may alfo be 

 obtained by providing a common chalybeate water* 

 and ufing it in thefe procefles, inftead of common 

 water. 



Having fucceeded fo well with this artificial Pyr- 

 mont water, I imagined that it might be poffible to 

 give ice the fame virtue, efpecially as cold is known 

 to promote the abforption of fixed air by watery 

 but in this I found myfelf quite miftaken. I put 

 feveral pieces of ice into a quantity of fixed air, 

 confined by quickfilver, but no part of the air was 

 abforbed in two days and two nights; but upon 

 bringing it into a place where the ice melted, the air
