1 88 Analyfis of the Air. 



Hence alfo it is probable, that there is 

 fome air in acid fpirits, which is reforbed 

 and fixed by them in diftillation. And this 

 is furthe rconfirmed from the many air- 

 bubbles which arife from Aqua-regia y in 

 the folution of gold ; for fince gold lofes 

 nothing of its weight in being diflblved, the 

 air cannot arife from the metalline part of 

 the gold, but muft either arife from the 

 Aqua-regia^ or from latent air in the pores 

 of the gold. 



Experiment LXXVI. 



A cubick inch of common Brimflone ex- 

 panded very little in diftillation in a glafs 

 retort 5 notwithftanding it had a great heat 

 given it, and was all diftilled over into the 

 receiver without flaming. It abforbed fome 

 air ; but flaming brimflone, by Experiment 

 103, abforbs much air. 



A good part of the air thus raifed from 

 feveral bodies by the force of fire, was apt 

 gradually to loofe its elafticity, in ftanding 

 feveral days 5 the reafon of which was, ( as 

 will appear more fully hereafter) that the 

 acid fulphureous fumes raifed with that air, 

 did reforb and fix the elaftick particles.
