274 Analyjis of the 'Air. 



thus prepared 3 + \ minutes ; yet it abforbed 

 but two thirds of the quantity of air which 

 it abforbed when there was no flannel in the 

 receiver. 



The reafon of which difference in the 

 quantities of elaflick air abforbed, appears 

 from Experiment 106, where leaft air was 

 always abforbed in leaft receivers, which was 

 the prefent cafe: For the flannel lining, be- 

 fides 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 receiver j for which 

 reafon lefs air alfo was abforbed. 



And we may further obferve, that lince the 

 Candle continued burning as long in a quan- 

 tity of air, equal but to two thirds of the re- 

 ceiver, as in the whole air of the receiver 5 

 this muft be owing to the Sal Tartar in the 

 flannel lining, which muft needs have abforbed 

 one third of the fuliginous vapours, which 

 arofe from the burning candle. Hence we may 

 not unreafonably conclude, that the pernicious 

 quality of noxious vapours in the air might, 

 in many cafes, be much rebated and qualified 

 by the ftrongly abforbing power of Salts.
