Through this _Membrane_, the _Lignous Body_ or _Seed-Branches_
distributed in the inner Coat, at last shoot downright two slender
Fibres, like two Navles, one into each _Lobe_ of the _Bean_. The places
where the said Fibres shoot into the _Lobes_, are near the _Basis_ of
the _Radicle_; and by their Blackishness well enough remark’d: but the
Fibres themselves are so very small, as scarcely to be discern’d: Yet in
a _Lupine_, of the larger kind, both the places where the Navel-Fibres
shoot into the _Lobes_ (which here from the _Basis_ of the _Radicle_
is more remote) and the Fibres themselves, are fairly visible. For the
_Seed-Branch_, upon its entrance into the Coat of the _Lupine_, is
presently divided into two _main Branches_, and those two into other
less; whereof some underly, others aloft, run along the Coat, and
towards its other end meet and are inosculated; where about two opposite,
shallow, round, and most minute Cavities, answerable to two Specks of
a _cartilaginous_ gloss, one in either _Lobe_, may be observed, which
Specks are the ends of the said _Navel-Fibres_, upon the ripening of
the _Seed_ there broken off. These Fibres, from the Superficies of each
_Lobe_, descend a little way directly down; presently, each is divided
into two Branches, one distributed into the _Lobes_, the other into the
_Radicle_ & _Plume_, in the manner as in the first Chapter is describ’d.
And thus far the History. I shall now only with a brief account of
the _Generation_ of the _Seed_, as hereupon dependent, conclude this
Discourse.
Let us say then, that the _Sap_ having in the _Root_, _Trunk_, and
_Leaves_, passed divers Concoctions and Separations, in the manner as
they are said to be perform’d therein; ’tis now at last, in some good
maturity, advanced towards the _Seed_.
The more copious and cruder part hereof is again seperated by a free
reception into the _Fruit_, or other Part analogous to it: being either
sufficiently ample to contain it, or at least laxe enough for its
transpiration, and so its due discharge. The more Essential part is
into the _Seed-Branch_ or Branches entertain’d; which, because they are
evermore of a very considerable length, and of a Constitution very fine,
the said _Sap_ thus becomes in its Current therein, as in the _Spermatick
Vessels_, still more mature.
In this mature estate, from the _seed-Branch_ into the Coats of the
_seed_, as into the Womb, ’tis next delivered up. The meaner Part
hereof again, to the outer, as _aliment_ good enough, is supplied.
The finer part is transmitted to the Inner; which, being, as is said,
a _Parenchymous_ and more spatious Body, the _Sap_ therefore is not
herein, as in the outer, a meer _aliment_; but in order to its being, by
Fermentation, farther prepared.
