equal to 2024 cubick inches. The quantity 
of air which was abforbed by the buniing 
Match was 19S cubick inches, equal to h 
part of the whole air in the veffel. 
I made the fame Experiment in, a lefler 
veffel z z aa (Fig. 35.) which contained 
but 594 cubick inches of air, in which 150 
cubick inches were abforbed, i. e, full % 
part of the whole air in the receiver : So 
that tho* more air is abforbed by burning 
Matches in large veffcls, where they burn 
longcft, than in fmall ones, yet more air, in 
proportion to the bulk of the veffel, is ' ab- 
forbed in fmall than in large veffels : If a 
frefh Match were lighted, and put into this 
infefted air, tho' it would not burn t 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 ; and it 
was the fame with Candles,
