Hooke, Robert, 1635-1703

"Micrographia Some Physiological Descriptions of Minute Bodies Made by Magnifying Glasses with Observations and Inquiries Thereupon"

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
other bodies, imitate, even almost by shaking them together. And thus for
instance may we find that the _Globular_ bullets will of themselves, if put
on an inclining plain, so that they may run together, naturally run into a
_triangular_ order, composing all the variety of figures that can be
imagin'd to be made out of _aequilateral triangles_; and such will you
find, upon trial, all the Surfaces of _Alum_ to be compos'd of: For three
bullets lying on a plain, as close to one another as they can compose an
_aequilatero-triangular_ form, as in A in the 7.
