Experiment the 2. 
7*tm %Q.i66o. About 1 1 of the Clock in the fore-nooo, we put 
* a Frog into a fmall Receiver , containing about 
1 54 OHfjc, Troy weight of water, out of which we had tolerably 
well drawn the Air, (fo that when we turned the cock under wa- 
ter^it fucked in about i^iounc, of water;)The Frog continued in 
it (the Receiver all the while under water ) lively enough till a- 
bout 5 of the clock in the afternoon, when it expired. The Frog 
at the firft feemed not to be much altered by the exudlion of the 
Air, but continued breathing both with her throat and lungs. 
Experiment the 5* 
Sept 6 i66x. included into a pretty large Receiver a cou- 
ple of Frogs newly taken, the one not above an inch 
long, and proportionally (lender, the other, very large and lufty* 
Whilft the Air was drawing out, the lefler Frog fkipped up and 
down very lively, and,foniewhat to our wonder, clambeied up 
feveral times to the fides of the Receiver, inlbmuch that he fome* 
times wrefted himfelf againft the fide of the glafi. When his body 
feemed to be perpendicular to the Horizon, if not in a reclining 
pofture, he continued to (kip up and down a while after the er- 
uftion of the Air, but within a quarter of an hour (meafured by 
a minute- watch) we perceived him to lye ftark dead with his bel- 
ly upwards. The other Frog, that was very large and ftrong, 
though he began to fwell much upon the withdrawing of the Air, 
and feemed to be diftreffed,by his frequently leaping up after the 
Air was drawn out, which he did not before, yet being as we faid 
very lufty^he held out half an hour,at which time it was remark- 
able, that the Pveceiver, though it had held out againft the pref- 
fureof the outward Air, during that fpace of time, notwith* 
ftanding tha t a piece of it had been cracked out, and was mend- 
ed with a cloth deep'd in Cementjyet at the end of the half hour, 
the weight of the outward Air fuddenly beat it in, and thereby 
brought theimprifoned Frog a reprieve, which hindered us from 
bringing the Experiment to an iflue*

a very (mall portable Receiver, we began to pump out 
the Air. At fir(t£he was lively enough, but when the Air begari 
to be confiderably withdrawn, (he appeared to be very much dif- 
quieted (leaping fometimes after an odd manner, as it were to get
