To this we anſwer:
That the Air which
moves along with our Earth, is as well li-
mited in certain bounds, as that which is in-
cluded in a Room. If you ask where theſe
Bounds are terminated: I anſwer, Neither
by the utmoſt parts of the World, nor yet
by the Concavity of the Moon's Orb, (as
Fromond{us} would have us affirm) but by
the Sphere of vaporous Air that encompaſſes
our Earth; or which is all one, by the Orb
of Magnetical Vigour, which proceeds from
it. And beſides, ’tis conſiderable, that all
Earthly Bodies are not only contained with-
in theſe limits, as things are in a cloſe Room,
but alſo as parts in that Whole to which
they belong.

Though the carrying along of the Me-

in a Ship, as the Flame of a Candle, Smoke,

which hath been ſaid of heavy Bodies, as a
Man leaping up, a Bullet deſcending, & c.
