WE recited in our nineteenth Ex
periment, how by drawing moſt
of the Air out of the Receiver, we made
the Water ſubſide by degrees in a Glaſs
not four Foot long: We ſhall now adde,
that in the like Experiment made in ſuch
a Tube, or a greater, it may be obſerv'd,
That when the Water begins to fall, there
will appear ſtore of bubbles faſten'd all a
long to the ſides of the Glaſs; of which
bubbles, by the agitation of the Veſſel
conſequent upon pumping, there will ariſe
good numbers to the top of the Water,
and there break; and as the Cylinder of
Water is brought to be lower and lower,
ſo the bubbles will appear more numerous
in that part of the Tube which the Water
yet fills; and the nearer the ſurface of the
Water, in its deſcent, approaches to theſe
periment, how by drawing moſt
