parcels of Air having now little more

Pipe which they pervaded, & by preſſing
every way againſt the ſides of it, to lift
upwards with them what Water they
found above them, without letting any
conſiderable quantity glide down along
the ſides of the Glaſs: So that ſometimes
we could ſee a bubble thruſt on before it
a whole Cylinder of Water of perhaps
an Inch high, and carry it up to the top
of the Pipe; though as we formerly no

All theſe things laid together ſeem'd
ſufficiently to confirm that, which the
conſideration of the thing it ſelf would
eaſily enough perſwade, namely, That
the Air, and ſuch like Bodies being under
Water, may be preſſ'd upon as well by
the Atmoſphere, as by the weight of the
incumbent Water it ſelf.
