Analyfis of the Air. 



ment was not very fudden nor violent, nor 

 the quantity of abforbing fumes large, that 

 the Antimony and Aqua-fort is generated a 

 quantity of air equal to 520 times the bulk 

 of the Antimony ; thus alto in the mixture 

 of Aqua-regia and Antimony, in Experiment 

 9 1, while at firft the ferment was fmall, then 

 air was generated; but when with the incrcaf- 

 ing ferment plenty of fumes arofc, then there 

 was a change from a generating to an abforb- 

 ing Irate. 



Since we find fuch great quantities of 

 elaftick air generated in folution of animal 

 and vegetable fubftances; it muftneedsbc 

 that a good deal does conftantly ariic, from 

 the diflolving of thefe aliments in the ftomach 

 and bowels, which diflblution it greatly pro- 

 motes : Some of which may very probably 

 be re-forbed again, by the fumes which arife 

 with them; for we fee in Experiment 83 

 that Oyiter (hell and Vinegar, Oyfter-fhcll 

 and Rennet, Oyfter-iheli and Orange juice, 

 Rennet alone, Rennet and Bread, firft generat- 

 ed and then ab lor bed air; but Oyfter-fhcll with 

 fome of the liquor of a Calve's ftomach which 

 had fed much upon Hay, did not generate air > •
