Analyfts of the Air . 2, 3 1 
I made the fame Experiment in a leffer 
veffel z>z>aa , (Fig. 3 5-) which contained 
but 594 cubick inches of air, in which 150 
cubick inches were abforbed 5 /. e . full ~ 
part of the whole air in the receiver : So 
that tho* more air is abforbed by burning 
Matches in large veffels, where they bum 
longeft, than in fmall ones, yet more air, 
in proportion to the bulk of the vcffel, is 
abforbed in fmall than in large veffels : If a 
frefh Match were lighted and put into this 
infe&cd air, tho' it would not burn l part 
of the time that the former Match burnt 
in frefh untainted air, yet it would abforb 
near as much air in that fhort time $ and it 
was the fame with Candles, 
Experiment CIV. 
Equal quantities of filings of Iron and 
Brimflone , when let fall on a hot Iron on 
the pedeftal under the inverted glafs z zaa? 
' (Fig. 35.) did in burning abforb much air ; 
and it was the fame with Antimony and 
Brimflone : Whence it is probable, that VnU 
cano's , whofe fewel confift chiefly of Brim • 
ftone , mix’d with feveral mineral and me- 
taline fubftances, do not generate, but ra- 
ther abforb air.
