3 o S Analyfis of the Air. 
will abforb air; yet if where the ferment was 
fo much greater, more elaftick air was ge- 
nerated by the fermenting mixture than was 
abforbed by the afeending fumes j then the 
quantity of new generated air, which I found 
between z z and a a> (Fig. 35.) when I mea- 
fured it, was equal to the cxcefs of what was 
generated above what was abforbed. 
And probably in this cafe the air was not 
abforbed fo much in proportion to the denfity 
of the fumes as in the firft cafe ; becaufe here 
the fulphureous fumes were much blended 
with watry vapours : For we find in Experi- 
ment 97, that fix times more was wafted in 
fumes in this cafe than in the other; and there: 
fore probably a good part of the cubick inch 
of water afeended with the vapour, and 
might thereby weaken its abforbing power : 
For watry vapours do not abforb elaftick air 
as the fulphureous ones do ; tho* by Experi- 
ment 1 20, a Candle abforbed more in a damp 
than in a dry air. 
And ’tis from thefe diluting watry vapours 
that filings of Iron with Spirit of Nitre and 
Water, abforbed lefs than with Spirit.of Nitre 
alone, for in both cafes it abforbs more than 
it generates. 
Thus
