and shape of every one of them, as to imitate exactly the curious and
Geometrical _Mechanisme_ of Nature in any one. Some coorse draughts, such
as the coldness of the weather, and the ill provisions, I had by me for
such a purpose, would permit me to make, I have here added in the Second
_Figure_ of the Eighth _Scheme_.[12]

In all which I observ'd, that if they were of any regular Figures, they
were always branched out with six principal branches, all of equal length,
shape and make, from the center, being each of them inclin'd to either of
the next branches on either side of it, by an angle of sixty degrees.

Now, as all these stems were for the most part in one flake exactly of the
same make, so were they in differing Figures of very differing ones; so
that in a very little time I have observ'd above an hundred several cizes
and shapes of these starry flakes.

The branches also out of each stem of any one of these flakes, were exactly
alike in the same flake; so that of whatever Figure one of the branches
were, the other five were sure to be of the same, very exactly, that is, if
the branchings of the one were small _Perallelipipeds_ or Plates, the
branchings of the other five were of the same; and generally, the
branchings were very conformable to the rules and method observ'd before,
in the Figures on _Urine_, that is, the branchings from each side of the
stems were parallel to the next stem on that side, and if the stems were
plated, the branches also were the same; if the stems were very long, the
branches also were so, &c.

Observing some of these figur'd flakes with a _Microscope_, I found them
not to appear so curious and exactly figur'd as one would have imagin'd,
but like Artificial Figures, the bigger they were magnify'd, the more
