1 9 6 Analyfis of the Air, 



event was, that we found fome fpoons full 

 of water with the Mercury in the Alodals, 

 which I then fufpe&ed to arife from the 

 moifture of the earthen retort and lute, and 

 am now confirmed in that fufpicion. It rained 

 inceffantly all the day, when I made this 

 prefent Experiment $ fo that when water is 

 obtained in the diftillation of Mercury, it 

 cannot be owing to a moifter temperature 

 of the Air. 



The effects of Fermentation on the Air. 



HAVING from the foregoing Experi- 

 ments feen very evident proof of the 

 production of confiderable quantities of true 

 elaftick air, from liquors and folid bodies, 

 by means of fire ; we (hall find in the fol- 

 lowing Experiments many inftances of the 

 production 5 and alfo of the fixing or abforb- 

 ing of great quantities of air by the fermen- 

 tation arifing from the mixture of variety of 

 folids and fluids : Which method of pro- 

 ducing and of abforbing, and fixing the elaf- 

 tick particles of air, by fermentation, feems 

 to be more according to nature's ufual way 

 of proceeding, than the other of fire.
