Now becauſe it has by very Learned
Men been doubted whether the ſwelling
of the Bladder may not have proceeded
from the Dilatation of the included Air,
but from the Texture of the Fibres,
which, being wont to keep the Bladder
extended when the Animal to whom it
belong'd was alive, may be ſuppoſ'd in
our Experiment to have return'd, like ſo
many Springs to their wonted extent, up
on the removal of the Ambient Air that

I ſay, has been doubted, we thought fit
to make this further tryall.

We let down into the Receiver with

up at the neck that there might be liberty
left to the Air that was not ſqueez'd out
