racting principle in the body of the Moon,
it would make that part to fall, or be mov'd out of its visible posture.
Next, the shape and position of the parts is such, that they all seem put
into those very shapes they are in by a gravitating power: For first, there
are but very few clifts, or very steep declivities in the ascent of these
Mountains; for besides those Mountains, which are by _Hevelius_ call'd the
_Apennine_ Mountains, and some other, which seem to border on the Seas of
the Moon, and those only upon one side, as is common also in those Hills
that are here on the Earth; there are very few that seem to have very steep
ascents, but, for the most part, they are made very round, and much
resemble the make of the Hills and Mountains also of the Earth; this may be
partly perceived by the Hills incompassing this Vale, which I have here
describ'd; and as on the Earth also, the middlemost of these Hills seems
the highest, so is it obvious also, through a good _Telescope_, in those of
the Moon; the Vales also in many are much shap'd like those of the Earth,
and I am apt to think, that could we look upon the Earth from the Moon,
with a good _Telescope_, we might easily enough perceive its surface to be
very much like that of the Moon.

Now whereas in this small draught, (as there would be multitudes if the
whole Moon were drawn after this manner) there are several little
Ebullitions, or Dishes, even in the Vales themselves, and in the
incompassing Hills also; this will, from this supposition, (which I have, I
think, upon very good reason taken) be exceeding easily explicable; for, as
I have several times also observ'd, in the surface of Alabaster so ordered,
as I before describ'd, so may the later eruptions of vapours be even in the
middle, or on the edges of the former; and other succeeding these also in
time may be in the middle or edges of these, &c. of which there are
Instances enough in divers parts of the body of the Moon, and by a boyling
pot of Alabaster will be sufficiently exemplifi'd.

To conclude therefore, it being very probable, that the Moon has a
principle of gravitation, it affords an excellent distinguishing Instance
in the search after the cause of gravitation, or attraction, to hint, that
it does not depend upon the diurnal or turbinated motion of the Earth, as
some have somewhat inconsiderately supposed and affirmed it to do; for if
the Moon has an attractive principle, whereby it is not only shap'
