stones_, all kinds of _Salts_, multitudes of _Earths_, and almost all kinds
of _fluid bodies_. And this is another propiety, which, though a little
superficially taken notice of by some, has not, that I know, been so much
as attempted to be explicated by any.

This propriety of bodies, as I think it the most worthy, and next in order
to be consider'd after the contemplation of the _Globular Figure_, so have
I long had a desire as wel as a determination to have prosecuted it if I
had had an opportunity, having long since propos'd to my self the method of
my enquiry therein, it containing all the allurements that I think any
enquiry is capable of: For, first I take it to proceed from the most simple
principle that any kind of form can come from, next the _Globular_, which
was therefore the first I set upon, and what I have therein perform'd, I
leave the Judicious Reader to determine. For as that form proceeded from a
propiety of fluid bodies, which I have call'd _Congruity_, or
_Incongruity_; so I think, had I time and opportunity, I could make
probable, that all these regular Figures that are so conspicuously
_various_ and _curious_, and do so adorn and beautifie such multitudes of
bodies, as I have above hinted, arise onely from three or four several
positions or postures of _Globular_ particles, and those the most plain,
obvious, and necessary conjunctions of such figur'd particles that are
possible, so that supposing such and such plain and obvious causes
concurring the _coagulating particles_ must necessarily compose a body of
such a determinate regular Figure, and no other, and this with as much
necessity and obviousness as a fluid body encompast with a _Heterogeneous_
fluid must be protruded into a _Spherule_ or _Globe_. And this I have _ad
oculum_ demonstrated with a company of bullets, and some few other very
simple bodies; so that there was not any regular Figure, which I have
hitherto met withall, of any of those bodies that I have above named, that
I could not with the composition of bullets or globules, and one or two
