That the Moon may be a World.

PROP. VII.

That thoſe Spots and brighter parts, which by
our ſight may be diſtinguiſhed in the Moon,
do ſhew the difference betwixt the Sea and
Land, in that other World.

FOr the clear proof of this Propoſition,
I ſhall firſt reckon up and refute the Opi-

of the Seas or Mountains, here below:

ſented there as in a Looking-Glaſs.
But none
of theſe Fancies can be true, becauſe the Spots
are ſtill the ſame, and not varied according to
the difference of places;
