the vapours would have been Jefs denfe, that 

 in that cafe much leis air would have been 

 abforbed, perhaps a great deal lefs than was 

 generated. 



In the fecond cafe of the IV alien Mineral, 

 Experiment 96. when inftead of abforbing, 

 it generated air, the parts of the compound 

 Aqua- forth were then more at liberty to act 

 by being diluted with an equal quantity of 

 water j whereby the ferment being more 

 violent, the particles which conftituted the 

 new elaftick air were thereby thrown oft in 

 greater plenty, and perhaps with a greater 

 degree of elafticity, which might carry them 

 beyond the fphere of attraction of the ful- 

 phureous particles. 



This is further illuftrated by Experiment 

 94. where filings of Iron and oil of Vitriol 

 alone generated very little, but the like quan- 

 tities of filings of Iron, with an equal quan- 

 tity of water, generated 43 cubick inches of 

 air \ and the like ingredients, with three times 

 that quantity cf water, generated 108 cubick 

 inches. 



And though the quantity of the afcending 

 fumes (which was in this cafe of the JValton 

 Mineral very great) mud needs in their afcent 

 abforb a good deal of elaftick air, (for they
