reaching 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
