In the next place, theſe Experiments
may teach us, what to judge of the vul
gar Axiom receiv'd for ſo many Ages
as an undoubted Truth in the Peripate
tick Schools; That Nature abhorres
and flys a Vacuum, and that to ſuch a de
gree, that no humane power (to go no
higher) is able to make one in the Uni
verſe; wherein Heaven and Earth would
change places, and all its other Bodyes
rather act contrary to their own Nature,
than ſuffer it. For, if by a Vacuum we
will underſtand a place perfectly devoid
of all corporeal Subſtance, it may be in
deed then, as we formerly noted be plau
