though, in this ffate, it may affiedt the tafle more 
fenlibly, it cannot be of fo much ufe in the flomach 
and bowels, as when the air is more firmly retained 
by the water, though, in confequence of it, it be 
lefs fenfible to the tafle. 
By the procefs defcribed in my pamphlet, fixed 
air may be readily incorporated with wine, beer, and 
almofl 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 tafle, 
communicated by fixed air, and which is very mani- 
feft in water, can hardly be perceived in wine, or 
any liquors which have much tafle of their cv/n. 
I fhould think that there can be no douot, but 
that water thus impregnated with fixed air mult 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 proceffes, inftead of common 
water. 
Having fucceeded fo well with this artificial Pyr- 
mont water, I imagined that it might be poflible to 
give ice the fame virtue, elpecially as cold is known 
to promote the abforption of fixed air by watery 
but in this I found myfelf quite miflaken. I put 
feveral pieces of ice into a quantity of fixed air, 
confined by quickiilver, but no part of the air was 
abforbed in two days and two nights j but upon 
bringing it into a place where the ice melted, the air
