partly that the Phænomenon we have been

bare ſubſiding of the Water that fill'd
the Tube, upon the taking off the preſ

as with fitter Inſtruments might perhaps
be poſſible; yet the expanſion of the
Air is likely to be rather greater then

Air was able to preſs away the Water at
the bottom of the Pipe, though that were
about two Inches below the ſurface of the
Water that was then in the Viol, and
would have been at leaſt as high in the
Pipe, if the Water had onely ſubſided and
not been depreſſed: So that it ſeems not
unlikely that if the Experiment could be
ſo made, as that the expanſion of the Air
might not be reſiſted by the Neighboring
