wherein the Lands and Seas are, as it were, ballanced: That thence also may proceed the non~appearance of any Clouds raised there, or of any Vapors considerable enough to be seen, as there are raised upon this Earth; and that this absence of Vapors is perhaps the cause, that no Crepuscle is there, as it seems there is none, my selfe at least not having hitherto been able to discerne any mark thereof: For, me thinks, it is not to be doubted, but that the reputed Citizens of the Moon might see our Crepuscle, since we see, that the same is without comparison stronger, than the Light afforded us by the Moon, even when she is full; for, a little after Sun-set, when we receive no more the first Light of the Sun, the sky is far clearer, than it is in the fairest night of the full Moon. Mean while, since we see in the Moon, when she is increasing or decreasing, the Light she receives from the Earth, we cannot doubt, but that the People of the Moon should likewise see in the Earth that Light, wherewith the Moon illuminates it, with perhaps the difference, there is betwixt their bigness. Much rather therefore should they see the Light of the Crepuscle, being, as we have said, incomparably greater. In the mean time we see not any faint Light beyond the Section of the Light, which is every where almost equaly strong, and we there distinguish nothing at all, not so much that cleerest part, which is called Aristarchus, or Porphyrites, as I have often tryed; although one may there see the Light, which the Earth sends thither, which is sometimes so strong, that in the Moon's decrease I have often distinctly seen all the parts of the Moon, that were not enlightned by the Sun, together with the difference of the clear parts, and the Spots, so far as to be able to discern them all. The shaddows also of all the Cavities of the Moon seem to be stronger, than they would be, if there were a second Light. For, although a far off; the shaddows of our Bodies, environed with Light, seem to Us almost dark; yet they doe not so appear so much, as the Shaddows of the Moon doe; and those that are upon the Edge of the Section,
