retort ; notwithftanding it had a great heat 
given it, and was all diftilled over into the 
receiver without flaming. It abforbed fomc 
air, but flaming brimftone by Experiment 
105, abforbs much air. 
A good part of the air thus raifed from 
fcveral bodies by the force of fire, was apt 
gradually to lofe its elafticity, in {landing 
feveral days j the reafon of which was (as 
will appear more fully hereafter) that the 
acid fulphureoLis fumes raifed with that air> 
did reforb and fix the elaftick particles. 
Experiment LXXVII. 
To prevent which I made life of the fol- 
lowing method of diftillation, viz. I fixt 
a leaden fyphon. Fig. 38. to the nofe of the 
iron retort r r , and then having immerfed 
the fyphon in the vefTel of water x x, I 
placed over the open end of the fyphon 
the inverted chymical receiver which was 
full of water j fo that as the air which was 
raifed in diftillation, paiTed thro* the water 
up to the top of the receiver ab^ z good 
part of the acid fpirit and fulphureous fumes 
were by this means intercepted and retain.
