above z z the furface of the water, was 

 equal to 2024 cubick inches. The quantity 

 of air which was abforbed by the burning 

 Match was 198 cubick inches, equal to A 

 part of the whole air in the veflel. 



I made the fame Experiment in a lefler 

 veflel z z a a ( Fig. 3 5-) which contained 

 but 594 cubick inches of air, in which 150 

 cubick inches were abforbed, /". e. full % 

 part of the whole air in the receiver : So 

 that tho' more air is abforbed by burning 

 Matches in large vcffels, where they burn 

 longeft, than in fmall ones, yet more air, in 

 proportion to the bulk of the veflel, is ab- 

 forbed in fmall than in large vcflcls : If a 

 frefh Match were lighted, and put into this 

 infc&ed air, tho' it would not burn f part 

 of the time that the former Match burnt 

 in frefh untainted air, yet it would abforb 

 near as much air in that fhort time 5 and it 

 was the fame with Candles.
