 The Candle continued burning under the re- 

 ceiver thus prepared 3 + i minutes, yet it 

 abforbed but two thirds of the quantity of 

 air, \^ch it abforbed when there was no 

 flangia in the receiver, 

 ^The reafon of which difference in the 

 quantities of elaftick air abforbed, appears 

 from Experiment 106 . where leaft air was 

 always abforbed in leaft receivers, which 

 was the prefent cafe : For the flannel lining, 

 befides the fpace it took up, could not be fo 

 clofely adapted, but that there was left a full 

 third of the capacity of the receiver, between 

 the lining and the receiver: So that the 

 Candle burnt in a bulk of air lefs by one 

 third than the whole capacity of the receivers 

 for which reafon lefs air alfo was abforbed. 

 And we may further obferve, that fince 

 the Candle continued burning as long in a 

 quantity of air ? equal but to two thirds of
