MicROGRAPHIA. 
Ebullitions, or Difhes, even in the Vales themfelves,and in the incompaf- 
fing Hillsalfo 5 this will, from this fuppofition, ( which I have, I think, up- 
on very good reafon taken) be exceeding eafily explicable; for, as I 
have feveral times alfo obferv'd, inthe furface of Alabafter fo ordered, 
as I before defcrib’d, fo may the later eruptions of vapours be evenin the 
middle, or on the edges of the former 5; and other fucceeding thefe alfo 
in time may be in the middle or edges of thefe, ec. of which there are 
Inftances enough in divers parts of the body of the Moon, and bya 
boyling pot of Alabafter will be fufficiently exemplifi'd. 
To conclude therefore, it being very probable, that the Moon has a 
principle of gravitation , it affords an excellent diftinguifhing Inftance 
in the fearch after the caufe of gravitation, or attraction, to hint, that it 
. does not depend upon the diurnal or turbinated motion of the Earth, as 
fome have fomewhat inconfiderately fuppofed and affirmed it to do; for 
if the Moon has an attractive principle, whereby it is not only fhap'd 
round , but does firmly contain and hold all its parts united, though 
many of them feem as loofe asthe fand on the Earth, and that the Moon 
isnot mov'd about its Center; thencertainly the turbination cannot be 
the caufe of the attraction of the Earth; and therefore fome other 
principle muft be thought of, that will agree with all the fecundary as 
wellas primary Planets. But this, Iconfefs, is but a probability, and 
not a demonftration, which (from any Obfervation yet made) it feems 
hardly capable of, though how fuccefsful future indeavours (promoted 
by the meliorating of Glafies, and obferving particular circumf{tances) 
may bein this, or any other, kind, muft be with patience expected.
