And in Experiment 95; there arc feveral 

 inftanccs of the air's being in like manner

 of Harts- horn with filings of Iron, and with 

 filings of Copper : And Spirit of Sal Am- 

 moniac with filings of Copper; and alio 

 filings of Iron and Water ; powdered Flint 

 and Compound Aquz-fuYiis ; powdered Bri-

It is probable from Experiment 103 and 

 106, where it was found that the thicket 

 the fuliginous vapours were, the fader they 

 abforbed the air, that if the above- mentioned 

 fermenting mixtures had not been confined 

 in clofe vefiels, but in the open air, where 

 the vapours would have been lefs denfe, that 

 in that cafe much lefs air would have been 

 abforbed, perhaps a great deal lefs than was 



generated. 



In the fecond cafe of the IValton mineral, 

 Experiment 96, when inftead of abibrbing, 

 it generated air, the parts of the Compound 

 Aquafortis were then more at liberty to 

 aft by being diluted with an equal quantity 

 of water 5 whereby the ferment being 

 more violent, the particles which confti-
