Analyfts of the Air. i 8 3 



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 brimftone 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 lofe its elafticity, in {landing 

 feveral days; 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. 



Experiment LXXVII. 



To prevent which I made ufe of the fol- 

 lowing method of diftillation, viz. I fixt 

 a leaden fyphon, Fig. 38. to the nofe of the 

 iron retort r r 5 and then having immerfed 

 the fyphon in the veffei of water x x, I 

 placed over the open end of the fyphon 

 the inverted chymical receiver ah which was 

 full of water $ fo that as the air which was 

 raifed in diftillation, paffed thro' the water, 

 up to the top of the receiver a b, a good 

 part of the acid fpirit and fulphureous fumes 

 were by this means intercepted and retain.
