Whereas they tell us, in the ſecond
place, that a bigger Body, as a Millſtone,
will naturally deſcend ſwifter than a leſs, as
a Pebble. I anſwer : This is not becauſe
ſuch a great Body is in it ſelf more eaſily
movable; but becauſe the bigger any thing
is which is out of its own place, the ſtron-
ger will be its natural deſire of returning
thither, and ſo conſequently the quicker its
motion. But now thoſe Bodies that move
circularly, are always in their proper ſcitu-
ations, and ſo the ſame reaſon is not apply-
able unto them. And then, whereas ’tis
ſaid, that Magnitude does always add to the
ſwiftneſs of a violent motion, (as Wind
will move a great Ship ſooner than a little
Stone): We anſwer, This is not becauſe a
Ship is more eaſily movable in it ſelf than a
little Stone: For I ſuppoſe, the Objector
will not think he can throw the one as far as
the other, but becauſe theſe little Bodies
are not ſo liable to that kind of vio-
lence, from whence their Motion does pro-
ceed.
