more air into the bladder twelve times du- 
ring the hour? yet fince he was almoft fufi 
focated in lefs than two minutes, by breath-* 
ing of himfelf to and fro the firft air in the 
bladder, he would by Experiment 106. on 
Candles, have died in lefs than two minutes, 
when one fourth of the old air remained 
in the bladder, immediately to taint the 
new admitted air from a man's lungs 5 fo 
that his continuing to live thro* the whole 
hour, mull be owing to the forcible dilata- 
tion of the lungs, by comprefting the blad- 
der, and not to the vivifying fpirit of air. 
For without that forcible dilatation, he had, 
after the firft 5 or 10 minutes, been certainly 
dead in lefs than a minute, when his pulfe 
was fo very low and weak, which I did not 
find to be revived barely by blowing 3 
parts in 4 of new air from the lungs of a 
man into the bladder : But it was conftant- 
ly roufed and quickned, whenever I increafed 
the dilatations of the lungs, by comprefling 
the bladder more vigoroufly 5 and that whe- 
ther it was at the beginning or end of each 
5 minutes, yet it was more eafily quickned, 
when the bladder was at any time newly 
filled, than when it was near empty.
