 ticles of the fuel and ambient air. 



From this manifeft attraction, action and

 phureous and claftick aereal particles, we 

 may not unrcafonably conclude, that what 

 we call the fire particles in Lime, and fevc- 

 ral other bodies, which have undergone the 

 fire, arc the fulphurcous and claftick parti- 

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

 ticles, while the Lime was hot, were in a 

 very active, attrafting and repelling flare ; 

 and being, as the Lime cooled, detained in 

 the folid body of the Lime, at the fcveral 

 attracting and repelling diftances, they then 

 happened to be at , they muft neceffarily 

 continue in that fixt ftate, notwithftanding 

 the ethereal medium, which is fuppofed 

 freely to pervade all bodies, be continu-

 the folid fubftance of the Lime is diflblved, 

 by the affufion of fome liquid, being there-

 to be influenced and agitated by each other's 

 attraftion and repulfion, upon which a vio-
