8270That the Moon may be a World. therefore the Beams muſt Sink into it, and can-
not ſo ſtrongly and clearly be reflected.
in ſpeculo ubi plumbum abr aſum fuerit, ſaith Gar-
dan, as in Looking-glaſſes where part of the
Lead is raſed off, and nothing left behind to
Reverberate the Image, the ſpecies muſt there
paſs through, and not back again;
ſo it is
where the Beams penetrate and ſink into the
ſubſtance of the Body, there cannot be ſuch an
immediate and ſtrong Reflexion, as when they
are beat back from the Superficies, and there-
fore the Sun cauſes a greater Heat by far upon
the Land than upon the Water.
Now as for
that Experiment where it is ſaid, that the wa-
ters have a greater brightneſs than the Land:
I anſwer, ’tis true only there where they re-
preſent the Image of the Sun or ſome bright
Cloud, and not in other places, eſpecially if
we look upon them at any great diſtance, as is
very plain by common Obſervation.
And ’tis certain, that from any high Moun-
tain the Land does appear a great deal brighter
than any Lake or River.
This may yet further be illuſtrated by the
ſimilitude of a Looking-glaſs hanging upon a
Wall in the Sun-ſhine, where, if the Eye be
not placed in the juſt line of Reflexion from
the Glaſs, ’tis manifeſt that the Wall will be
of a brighter appearance than the Glaſs.
indeed in the Line of Reflexion, the Light of
the Glaſs is equal almoſt unto that which comes
immediately from the Sun it ſelf;
but now
this is only in one particular place, and ſo is
not like that Brightneſs which we diſcern in
the Moon, becauſe this does appear
