1reaching as low as the ſurface of the ſub
jacent Water, gave us cauſe to think
that if our Pipe had not been broken it
would have expanded it ſelf much fur
ther: Wherefore we took out the little
Tube, and found that beſides the twenty
ſix diviſions formerly mention'd, the
Glaſs bubble and ſome part of the Pipe
to which the divided Parchment did not
reach, amounted to ſix diviſions more.
Whereby it appears that the air had taken
up one and thirty times as much room as
before, and yet ſeem'd capable of a much
greater expanſion, if the Glaſs would
have permitted it. Wherefore, after the
former manner, we let in another bubble,
that by our gueſs was but half as big as
the former, and found, that upon the ex
ſuction of the Air from the Receiver, this
little bubble did not onely fill up the
whole Tube, but (in part) break through
the ſubjacent Water in the Viol, and
thereby manifeſt it ſelf to have poſſeſſed
ſixty and odde times its former room.

Theſe two Experiments are mention'd
to make way for the more eaſie belief of
that which is now to follow. Finding
then that our Tube was too ſhort to ſerve
our turn, we took a ſlender Quill of Glaſs
to make way for the more eaſie belief of
