244 Analyfis of the Air. 



whereby a continued fucceffion of frefti air 

 may be abforbed by the blood. 



And in the analyfis of the blood, either 

 by fire or fermentation in Exper. 49 and 80, 

 we find good plenty of panicles ready to re- 

 fume the elaftick quality of air : But whe- 

 ther any of thefe air particles enter the 

 blood by the lungs, is not eafie to deter-

 vegetable or animal food. Yet when wc 

 confider how much air continually lofes 

 its elaftieity in the lungs, which feem pur- 

 pofely framed into innumerable minute me-

 feize, and bind that volatile Hermes : It 

 makes it very probable, that thofe particles 

 which are now changed from an elaftick re-
