ther probable from hence, ^iz. char the whole 
Qiiandry of Air admitted at feveral times, is 
equal or nearly equal to the Qtiantity of ful- 
phureous Air a fo that both Airs are at the 
fame time contained within the Space a z. 
p. When Mercury is diflblved in compound 
Fortis^ the Vapour arifing from that 
Solution will alfo abforb frefli Air. 
10. The feveral Airs tainted with the Fumes 
of Vinegar and Oyfter-fliell, Oil of Vitriol 
and Oyfeer-fiiell, Belemniccs and Vinegar, did 
not abforb Air : But the Air of Bclemnites 
and Spirit of Nitre did abforb feme frefli ad- 
mitted Air, as did the Airs diftilled from Tar- 
tar and Newcaflle Coal ; but Air diftilled from 
an Ox’s Tooth did not abforb any. 
11. Since we have under this Experiment 
fo many Inftances of the brisk Agitation and 
EfFervefcence, which arifes from the Mixture 
of frefli Air, with Air which is ftrongly im- 
pregnated with fulphurcous Fumes, which 
are raifed by EfFervefcence from feveral mine- 
ral Subfiances ; and fince ws have alfo from 
other Experiments many Proofs of the brisk 
Aftion and Reailion, there is between elaftic 
Air and fulphureous Particles, may we not 
with good Reafon conclude, chat the irkfome 
Heat
