1the Beetle; we ſhall ceaſe to wonder at the Effect, which doth not
in the leaſt exceed the terms of Natural Conſtitutions, and of
what hath been ſpoken. Let us, for better underſtanding, give an
example thereof in particular Terms. There is a Beetle, which ha
ving four degrees of Reſiſtance, is moved by ſuch a Force, that
being freed from it in that term where it maketh the Percuſſion, it
would, meeting with no ſtop, go ten Paces beyond it, and in that
term a great poſt being oppoſed to it, whoſe Reſiſtance to Moti
on is as four thouſand, that is, a thouſand times greater than that of
the Beetle, (but yet is not immoveable) ſo that it without mea
ſure or proportion exceeds the Reſiſtance of the Beetle, yet the
Percuſſion being made on it, it ſhall be driven forwards, though in
deed no more but the thouſandth part of the ten Paces which the
Beetle ſhall be moved: and thus in an inverted method, changing
that which hath been ſpoken touching the other Mechanical Effects,
we may inveſtigate the reaſon of the Force of the Percutient. I
know that here ariſe difficulties and objections unto ſome, which
they will not eaſily be removed from, but we will freely remit them
to the ^{*} Problems Mechanical, which we ſhall adjoyn in the end of
this Diſcourſe.
