198 Analyjts of the' Air. 



Have we not reafon alfo hence to conclude, 

 that the energy of acid fpirits may, in fome 

 meafure, be owing to the ftrongly attracting 

 air-particles in them; which active princi- 

 ples may give an impetus to the acid fpicu/tf, 

 as well as the earthy oily matter, which is 

 found in thefe acid fpirits? 



There are, we fee, alfo great ftore of air- 

 particles found in the Analyfis of the blood, 

 which arifes doubtlefs as well from the ferum 

 as from the cra[f anient um^ for all the animal 

 fluids and folids have air and fulphur in them : 

 Which ftrongly attracting principles feem 

 to be more intimately united together in the 

 more perfect and elaborate part of it, its red 

 globules; fo that we may not unreafonably 

 conclude, that air is a band of union here as 

 well as in Salts : And accordingly we find the 

 greateft plenty of air in the moft folid parts 

 of the body, where the cohefion of the parts 

 is the ftrongeft ; for by comparing Experi- 

 ment 49. and 51. we fee that much more air 

 was found in the diftillation of horn, than of 

 blood. And the cohefion of animal fubftances 

 was nor, as we find by the fame Experiment, 

 diflblved even in the blood, without confi- 

 derable violence of fire ; tho' it is fometimes 

 dene to a fatal degree in our blood, by that
