s of Stars discoverable by the _Telescope_, and the
variety of their magnitudes: 78. Stars distinguisht in the _Pleiades_: that
there are degrees of bigness even in the Stars accounted of the same
magnitude: the longer the Glasses are, and the bigger apertures they will
indure, the more fit they are for these discoveries: that 'tis probable,
longer Glasses would yet make greater discoveries. 5. Stars discover'd in
the _Galaxie_ of _Orion_'s Sword._

Observ. 60. Of the Moon.

_A description of a Vale in the Moon; what call'd by _Hevelius_ and
_Ricciolus_, and how describ'd by them: with what substances the hills of
the Moon may be cover'd. A description of the pits of the Moon, and a
conjecture at their cause: two Experiments that make it probable, that of
the surface of boyl'd Alabaster dust seeming the most likely to be
resembled by eruptions of vapours out of the body of the Moon: that
Earthquakes seem to be generated much the same way, and their effects seem
very similar. An Argument that there may be such variations in the Moon,
because greater have been observ'd in the Sun: because substance of the
Moon and Earth seem much alike: and because 'tis probable the Moon has a
gravitating principle: this is argued from several particulars. The reason
why several pits are one within another. The use that may be made of this
Instance of a gravity in the Moon._
