re-action of thcfc particles, which ebullition 

 ccafes not, till one part of the elaftick par- 

 ticles arc fubdued and fix'd by the ftron 

 attraction of the fulphur, and the other part 

 is got beyond the fphere of its attraction, 

 and thereby thrown off into true permanent 

 air : And that this is a probable folution 

 of the matter, there is good reafon to con- 

 clude, from the frequent inftances we have 

 in many of the foregoing Experiments, that 

 plenty of elaftick air is at the fame time 

 both generated and abforbed by the fame 

 fermenting mixture ; fomc of which were 

 obferved to generate more air than they ab- 

 forbed, and others e contra abforbed more 

 than they generated, which was the cafe 



of Lime. 



Experiment CXIX. 



And that the fulphureous and aereal par- 

 ticles of the fire are lodged in many ofthofe 

 bodies which it afts upon, and thereby con- 

 siderably augments their weight, is very evi- 

 dent in Minium or Red Lead, which is ob- 

 ferved to increafe in weight about h part 



in undergoing the a&ion of the fire. The
