be there found, and {uppofing alfo a poffibility of the generation of tt 
internal elajtical body (whether you will call it sath vapours ) a 
not unlikely. I fay, but that there isin the Moon.a rinciple of gravita- 
tion, fuch as inthe Earth. And to make this Seobabile, I think, we need 
no better Argument, then the roundnefs, or globular Figure of the bos 
dy of the Moon it {elf, which we may perceive very plainly by the Te 
lefcope, to be ( bating the fmall inequality of the Hills and Vales init, 
which are all of them likewife fhap'd, or levelled, as it were, tw anifwer 
to the center of the Moons body }) perfectly of @ Spherical figure,’ that 
is, all the parts of it are forang’d ( bating the comparitively {mall rug- 
gednefS ‘of the Hills and Dales )) that the outmtoft bounds of themare 
equally diftant. from the Center of the Moon,’ and confequently, it is 
exceedingly probable alfo, that they are equidiftant from the Center of 
gravitation; and indeed, the figure of die hupeeRcia! parts of the Moon 
are fo exactly thap'd, according as they fhould be, ‘fuppofing it had a 
gravitating principle «as the Earth has, that’even the figure of thofe 
parts themfelves is of fufficient efficacy to make the gravitation, and the 
other two fuppofitions probable: fo that the other fippofitions may be 
rather prov d ‘by this'confiderable Circumftance, ‘or Obfervation, ‘then’ 
this: fuppos'd Explication can by ‘them 5 for he that thall attentively 
obferve with an excelent Tele/eope, how ali the Circumftances, notable in 
the fhape of the fuperficial parts, are, as it were, exactly adapted to 
fede-wvieh Gich 4 principle will he wem Conidete Che ulaal mepiod GFN: 
tured its other proceedings, find abundant argument to believe it to have 
really there alfofuch a principle; for Tcould never obferve,among all'the 
mountainous or prominent parts of the Moon ( whereofthere isa huge 
variety ) that any one part of it was plac’d in fuch a manner,that if there 
fhould be a gravitating, or attracting principle in the body of the Moon, 
it would make that part to fall, or be mowd out of its vifible pofture. 
Next, the fhape and pofition of the parts is fuch, that they all feem put 
into thofe very fhapes they are inby a gravitating power - For firft,there 
are but very few clifts, or very fteep declivities in the afcent of thefe 
Mountains; for befidesthofe Mountains, which are by Hevelizs call’d the 
Apennine Mountains, and fome other, which feem to border on the Seas 
of the Moon, and thofe only upon one fide, asis common alfoin thofe 
Hills that arehere on the Earth; there are very few that feemto have 
eg {teep afcents, but, for the moft part, they are made very round, 
and much refemble the make of the Hills and Mountains allo of the 
Earth ; thismay be partly perceived by the Hills incompafling this Vale, 
which Ihave here defcrib’d ; and as on the Earth alfo, the middlemoft 
of thefe Hills feems the higheft, fo is it obvious alfo, through a good Te- 
lefeope, in thofe of the Moon ; the Vales alfo in many are much fhap'd 
like thofe of the Earth, and Iam apt to think, that could we look upon 
the Earth from the Moon, with a good Telefcope, we might eafily enough 
perceive its furface to be very much likethat of the Moon. 
Now whereas in this {mall draught, (as there would be multitudes if 
the whole Moon were drawn after this manner) there are feveral little 
Ebullitions,
