ſuſpected that the depreſſion of the Li

whereinto the exhaling and impriſon'd
ſteams were put, by that heat which is
wont to reſult from that action of corro

the Viol and the open-mouthed Glaſs to
remain as they were, in a Window, for
three or four days and nights together; but
looking upou them ſeveral times during
that while, as well as at the expiration of
it, the whole cavity of the Glaſs bubble,

ſeſſ'd by Air, ſince by its ſpring it was a
ble for ſo long to hinder the expell'd and
ambient Liquor from regaining its former
place. And it was remarkable, that juſt

the other Glaſs, upon the application
of a warm hand to the convex part of the
bubble; the Impriſon'd ſubſtance readily
dilated it ſelf like Air, and broke through
the Liquor in divers bubbles, ſucceeding
one another.
