Nor may we think that the Earth's Shadow
can Cloud the proper Light of the Moon from
Appearing, or take away any thing from her
Inherent Brightneſs; for this were to think a
Shadow to be a Body, an Opinion altogether

You will ſay, perhaps, that then the near-

pearance.
I Reply, this cannot be; for then why does
Mars ſhine with his wonted Redneſs, when
