whereby a continued fucceffion of frclh ak 

 may be abforbed by the blood. 



And in the analyfis of the blood, either 

 by fire or fermentation inExper. 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- 

 mine 5 becaufe there is certainly great (lore 

 of air in the food of animals, whether it be 

 vegetable or animal food. Yet when we 

 confider how much air continually lofes 

 its elafticity in the lungs, which feem pur- 

 pofely framed into innumerable minute me- 

 anders, that they may thereby the better 

 feize, and bind that volatile Hermes : It 

 makes it very probable, that thole particles 

 which are now changed from an elaftick re- 

 pulfive, to a ftrongly attra&ing ilate, may 

 eafily be attracted thro' the thin partition of 

 the vefkles, by the fulphureous particles 

 which abound in the blood. 



And nature feems to make ufe of the like 



artifices in vegetables, where we find that 



air is freely drawn in 5 not only with the 



principal fund of nourifhment at the root,
