4k%^ °f the Atr ' 1 8 3 



retort ; notwithstanding it had a great heat 

 civen it, and was all diftillcd over into the 

 receiver without flaming. It abforbed fomc 

 air, but flaming brimflone by Experiment 



103, 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 Handing 

 fcveral days; the rcafon of which was (as 

 will appear more fully hereafter) that the 

 acid fulphureous fumes raifed with that air, 

 did rcibrb and fix the elaftick particles. 



Experiment LXXVII. 



To prevent which I made ufe of the fol- 

 lowing method of diftillation, viz. 1 fixt 

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

 iron retort r r j and then having immcricd 

 the fyphon in the veffel of water x x, I 

 placed over the open end of the fyphon 

 the inverted chymical receiver ab which was 

 full of water \ fo that as the air which was 

 raifed in diftillation, gaffed 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.
