From this manifeft attraction, action and 

 reaftion, that there is between the acid, ful- 

 phureous and elaftick aereal particles, we 

 may not unreafonably conclude, that what 

 we call the fire particles in Lime, and feve- 

 ral other bodies, which have undergone the 

 fire, are the fulphureous and elaftick parti- 

 cles of the fire fixt in the Lime 5 which par- 

 ticles, while the Lime was hot, were in a 

 very aCtive, attracting and repelling ftatej 

 and being, as the Lime cooled, detained in 

 the folid body of the Lime, at the feveral 

 attracting and repelling diftances, they then 

 happened to be at, they muft neceffarily 

 continue in that fixt date, notwithstanding 

 the ethereal medium , which is fuppofcd 

 freely to pervade all bodies, be continu- 

 ally folliciting them to aCtion : But when 

 the folid fubftancc of the Lime is dhTolved, 

 by the affufion of fome liquid, being there- 

 by emancipated, they are again at liberty 

 to be influenced and agitated by each other's 

 attraction and repulfion, upon which a vio-
