nutes more he fell down quite dead, yet
with Convulſions far milder then thoſe
wherewith the two Birds expired. This
alacrity ſo little before his death, and his
not dying ſooner then at the end of the
eighth minute, ſeem'd aſcribable to the
Air (how little ſoever) that ſlipt into the
Receiver. For the firſt time, thoſe Con

Theſe Experiments ſeem'd the more
ſtrange, in regard, that during a great part of
thoſe few minutes the Engine could but
conſiderably rarefie the Air (and that too,
but by degrees) and at the end of them

we have formerly ſaid of our not being
able to draw down Water in a Tube, with
