1up at the neck: This done, and the Air
being in ſome meaſure ſuck'd out of the
Pneumatical Glaſs (if I may ſo call it)
the Bladder, mention'd at the beginning
of our Experiment, appear'd extended e
very way to its full Dimenſions; whereas
neither of the two others did remarkably
ſwell, and that whoſe neck was not ty'd
ſeem'd very little, if at all leſs wrinkl'd
then when it was put in.

We made likewiſe a ſtrong Ligature a
bout the middle of a long Bladder part
ly empty'd, and upon the drawing the
Air out of the Receiver, could obſerve
no ſuch ſwelling betwixt the Ligature and
the Neck of the Bladder, which had been
purpoſely left open, as betwixt the ſame
Ligature and the bottom of the Bladder,
whence the included Air could no way
get out.

But a further and ſufficient manifeſtati
on whence the intumeſſence of the Blad
der proceeds, may be deduc'd from the
following Experiment.
