And of this Experiment theſe two Phæ
nomena may be taken notice of: The one,
that the Bladder at its breaking gave a
great report, almoſt like a Craker: And
the other, That the Air contain'd in the
Bladder, had the power to break it with
the mention'd Impetuoſity, long before
the ambient Air was, all or near all, drawn
out of the Receiver.
