more and more of the Air in the Recei

And that it may appear that this plump

ſurmounting of the debilitated Spring of
the ambient Air remaining in the Veſſel,
by the ſtronger Spring of the Air remain

of the Stop-cock, and by degrees allow'd
the external Air to return into the Recei
ver: Whereupon it happen'd, as was ex
pected, that as the Air came in from with
out, the diſturb'd Air in the Bladder, was
proportionably compreſſ'd into a narrow
er room, and the ſides of the Bladder
grew flaccid, till the Receiver having re
admitted its wonted quantity of Air, the
Bladder appear'd as full of wrinkles and
cavities as before.
