314 Analyfis of the Air, 



endued with a property of reluming their 

 elaftick flate, whenever they were difen»a- 

 ged from that mafs, in which they were 

 fixed; that thereby this beautiful frame of 

 things might be maintained, in a continual 

 round of the production and diffolution of 

 animal and vegetable bodies. 



The air is very inftrumentai in the pro- 

 duction and growth of animals and vegeta- 

 bles, both by invigorating their feveral juices, 

 while in an elaftick active ftate, and alfo by 

 greatly contributing in a fix'd ftate to the 

 union and firm connection of the feveral 



\ 



condiment parts of thofe bodies, viz. their 

 water, fait, fulphur and earth. This band of 

 union, in conjunction with the external air, 

 is alfo a very powerful agent in the diflblu- 



tion and corruption of the fame bodies, for 

 it makes one in every fermenting mixture ; 

 the action and re-action of the aereal and ful- 

 phureous particles is in many fermenting 

 mixtures fo great, as to excite a burning 

 heat, and in others a fudden flame : And 

 it is we fee by the like action and re-ac- 

 actton of the fame principles, in fuel and the 

 ambient air, that common culinary fires are 



produced and maintained.
