The Motion of a Bullet is violent, and againſt its Nature, which does ſtrongly in-
cline it to move downwards. Whereas
the Earth being conſidered as whole, and in
its proper place, is not heavy, nor does
it contain any repugnancy to a Circular Mo-
tion.

The chief Argument on which our
Adverſaries do moſt inſiſt, is this: If there
11Ariſtor. de
Cæbo, l. 2.
c. 13. were ſuch a Motion of the Earth as is ſup-
poſed; then thoſe Bodies which are ſevered
from it in the Air, would be forſaken by it.
The Clouds would ſeem to riſe and ſet as
the Stars. The Birds would be carried a-
way from their Neſts. No heavy Body
could fall perpendicular. An Arrow or Bul-
let being ſhot from Eaſt to Weſt, by the
ſame violence, will not be carried an equal
diſtance from us, but we ſhould, by the re-
volution of our Earth, overtake that which
was ſhot to the Eaſt, before it could fall. If
a Man, leaping up, ſhould abide in the Air
but one ſecond ſcruple of an hour, or the
ſixtieth part of a minute, the Earth, in that
ſpace, would withdraw it ſelf from him
almoſt a quarter of a mile. All theſe, and
many other ſuch ſtrange Inferences, which
are directly contrary to ſenſe and expe-
rience, would follow from this motion of
the Earth.
