10 Many of the _lateral_ branches had _collateral_ branches (if I may so
call them) as qm had many such as st, and most of those again
_subcollateral_, as vw, and these again had others less, which one may call
_laterosubcollateral_, and these again others, and they others, &c. in
greater Figures.
11 The branchings of the main Stems joyn’d not together by any regular
line, nor did one side of the one lie over the other side of the other, but
the small _collateral_ and _subcollateral_ branches did lie at top of one
another according to a certain order or method, which I always observ’d to
be this.
12 That side of a _collateral_ or _subcollateral_, &c. branch, lay over the
side of the _approximate_ (as the feathers in the wing of a Bird) whose
branchings proceeded parallel to the last biggest stem from which it
sprung, and not to the biggest stem of all, unless that were a second stem
backwards.
13 This rule that held in the branchings of the _Sexangular Figure_ held
also in the branchings of any other great or small stem, though it did not
proceed from a center.
14 The exactness and curiosity of the figuration of these branches, was in
every particular so transcendent, that I judge it almost impossible for
humane art to imitate.
15 Tasting several cleer pieces of this _Ice_, I could not find any
_Urinous_ taste in them, but those few I tasted, seem’d as _insipid_ as
water.
16 A figuration somewhat like this, though indeed in some particulars much
more curious, I have several times observ’d in _regulus martis stellatus_,
but with this difference, that all the stems and branchings are bended in a
most excellent and regular order, whereas in _Ice_ the stems and branchings
are streight, but in all other particulars it agrees with this, and seems
indeed nothing but one of these stars, or branched Figures frozen on
_Urine_, distorted, or wreathed a little, with a certain proportion: _Lead_
also that has _Arsenick_ and some other things mixt with it, I have found
to have its surface, when suffer’d to cool, figured somewhat like the
branchings of _Urine_, but much smaller.
17 But there is a _Vegetable_ which does exceedingly imitate these
branches, and that is, _Fearn_, where the main stem may be observ’d to
shoot out branches, and the stems of each of these _lateral_ branches, to
send forth _collateral_, and those _subcollateral_ and those
_laterosubcollateral_, &c. and all those much after the same order with the
branchings, divisions, and subdivisions in the branchings of these Figures
in frozen _Urine_; so that if the Figures of both be well consider’d, one
would ghess that there were not much greater need of a _seminal principle_
for the production of _Fearn_, then for the production of the branches of
_Urine_, or the _Stella martis_, there seeming to be as much form and
beauty in the one as in the other.
