derable time j and ftill the air was but weakly in-

olives, in the laft mentioned experiment j and it 
feems to be probable, that, the longer this acid va- 
pour had continued in contadt with the oil, the more 
phlogifton it would have extracted from it. It is 
not improbable, but that, in the intermediate ftate, 
before it becomes inflammable air, it may be nearly 
of the nature of common air. 
Bees-wax abforbed this vapour very flowly. About 
the bignefs of a hazel-nut of the wax being put to 
three ounce meafures of the vapour, the vapour was 
diminilhed one half in two days, and, upon the admifi 
fion of water, half of the remainder alfo difappeared. 
This air was ftrongly inflammable. 
Charcoal abforbed this vapour very fall. About 
one fourth of it was rendered immifcible in water, 
and was but weakly inflammable. 
A fmall bit of phofphorus, perhaps about half a 
grain, fmoked, and gave light in the vapour of fpirit 
of fait, juft as it would have done in common aif 
confined. It was not fenfibly wafted after continuing 
about twelve hours in that ftate, and the bulk of the 
vapour was very little diminilhed. Water being ad- 
mitted to it abforbed it as before, except about one 
fifth of the whole, which was but weakly inflam- 
mable. 
Putting feveral pieces of fulphur to this vapour, 
it was abforbed but flowly. In about twenty-four 
hours about one fifth of the quantity had difappeared ; 
and water being admitted to the remainder, very little
