!E pafilng of Air through a red hot <31afs Tube 
into an exhaufted Receiver, had no manner of 
i ce on a Sparrow put into the fame: But upon 
paffing of Air through red hot Charcoal, before it en- 
ter’d the Tube that convey’d it into the exhaufted Re- 
ceiver, the fore-mentioned Animal, in that Medium in 
about a quarter of a Minute, gave figns of prefently ex- 
piring $ but being taken out at the fame time did reco- 
ver, and continued living and well for fome Days after. 
Yet it was concluded, had the Birds continuance in the 
Receiver been but double that time, her recovery would 
have been very doubtful. I have likewife try’d Air pafs’d 
through the Flames of Spirit of Wine, and Oil of Turpen- 
tine i The Effeft was much the fame as to the Spirit of 
Wine, the Flame of a Candle being immediately extin- 
guilh’d upon its being plung’d into it : But the Air which 
pafs’d through the Flame of the Oil of Turpentine 
took fome Un&ious Fumes along with it into the ex- 
haufted Receiver 5 which Fumes, upon the near approach 
a lighted Candle, fuddenly took fire, and continued to 
•burn on the upper Surface, till they were ftifled by co- 
vering clofe the Receiver : And upon feveral Repetitions » 
it anfwer’d much the fame, till the whole quantity of 
Fume was confura’d.
