a pretty large Cat immediately plung’d into it : The 
Cover being laid on again, the Cat immediately fell 
into Convulfions, and in lefs than a Minute appeared 
without any fign of Life. Then being taken out of the 
Receiver and laid on the Floor, (he continued as Dead 5. 
bm in lefs that a Minute of time (he began to difcover 
Life by motion in her Eyes, and after 2 or 3 hideous 
Squalls, {he began to recover apace 5 but was very fierce, 
and did fpit and (as well as her Weaknefs would fuffer 
her) at any one* that offer’d to touch her ^ and it feem’d 
hazardous for any one then to attempt it. But after half 
an hours time, or thereabouts, as her Strengrh'and Eafe 
recovered, fo her former Temper encreafeci upon her, 
fuffering herfelf to be handled without any fign of. 
fierceneft, as before. 
As to the Effeft, which the fame fort of Fa&itibus Air 
has upon Flame, take as follows. 
i no fooner came to plunge a lighted Candle into it, but. 
it was immediately extinguifb’d : And this Ifeveral times, 
obferv’d, that when the Candle was (lowly immers’d, fo. 
much of the Wick ( which before was lighted) as came 
but within the verge of the Glafs, died > and fa the 
reft fuceefiively, as it defeended to the fame- place : And 
this upon feveral repetitions, anfwer’d much the fame.. 
But in fome time, as the common Air came to mix with 
it, one might plunge the lighted Candle lower and low- 
er,. hefore it did go out, till at laft it would remain, 
burning at bottom. 
As to the Elafticity and Speeifick Gravity of the fore- 
mention’d Medium, L have made feveral try a Is, ("and.! 
think very accurate,) but find it no ways differing from. 
Common Air,, in refpedt to thofe Properties. 
Hence it follows,. 
That the foregoing Effe<ft, is no ways affifted from, any 
Impexfe&ion or. defe<ft in the laft mentioned Properties 1
