SALV. There is a great diſparity between the caſe of the Ship

and
that of the Earth, if the Terreſtrial Globe be ſuppoſed to have
a
diurnal motion.
For it is a thing very manifeſt, that the
tion
of the Ship, as it is not natural to it, ſo the motion of all thoſe
things
that are in it is accidental, whence it is no wonder that the
ſtone
which was retained in the round top, being left at liberty,
deſcendeth
downwards without any obligation to follow the
tion
of the Ship.
But the diurnal converſion is aſcribed to the
Terreſtrial
Globe for its proper and natural motion, and
quently
, it is ſo to all the parts of the ſaid Globe; and, as being
impreſs
'd by nature, is indelible in them; and therefore that ſtone
that
is on the top of the Tower hath an intrinſick inclination of
revolving
about the Centre of its Whole in twenty four hours, and
this
ſame natural inſtinct it exerciſeth eternally, be it placed in any
ſtate
whatſoever.
And to be aſſured of the truth of this, you
have
no more to do but to alter an antiquated impreſſion made
in
your mind; and to ſay, Like as in that I hitherto holding it to
be
the property of the Terreſtrial Globe to reſt immoveable about
its
Centre, did never doubt or queſtion but that all whatſoever
particles
thereof do alſo naturally remain in the ſame ſtate of reſt:
So
it is reaſon, in caſe the Terreſtrial Globe did move round by
natural
inſtinct in twenty four hours, that the intrinſick and
ral
inclination of all its parts ſhould alſo be, not to ſtand ſtill, but

to
follow the ſame revolution.
And thus without running into
any
inconvenience, one may conclude, that in regard the motion
conferred
by the force of ^{*}Oars on the Ship, and by it on all the
things
that are contained within her, is not natural but forreign, it
is
very reaſonable that that ſtone, it being ſeparated from the ſhip,
