Analyfis of the Air. 231 



The Candle cannot be lighted again in 

 this infeded air by a burning glafs : But if 

 I firft. lighted it, and then put it into the 

 fame infeded air, tho' it was extinguiflied 

 in f part of the time, that it would burn in 

 the fame veffel, full of frcfh air 5 yet it 

 would deftroy the elafticity of near as much 

 air in that fhort time, as it did in five times 

 that fpace of time in frefh air; this I re- 

 peated feveral times, and found the fame 

 event : Hence a grofs air which is loaded 

 with vapours, is more apt in equal times to 

 lofe its eiafticity in greater quantities, than. 

 a clear air. 



I obferve that where the veffelsare equal, 

 and the fize of the Candles unequal, the e- 

 lafticity of more air will be deftroyed by 

 the large than by the fmall Candle : And 

 where Candies are equal, there mod air in 

 proportion to the bulk of the veffel will 

 be abforbed in the fmalleft veffel: Tho* 

 with equal Candles there is always moft 

 elaftick air deftroyed in the largeft veffel, 

 where the Candle burns longeft. 



I found alio in fermenting liquors, that 

 ceteris paribus, more air was either gene- 

 rated or abforbed in large, than in fmall
