And the _Sap_ being duly prepared here, it next passeth into all the
Branches of the _Seminal Root_, and so under a fifth Government. Wherein
how delicate ’tis now become, we may conceive by the proportion betwixt
the _Parenchyma_ and this _Seminal Root_; so much only of the best
digested _Sap_ being discharged from the whole Stock in that, as this
will receive. And this, moreover, as the _Parenchyma_, with its proper
Seminalities being endowed; the _Sap_, for the supply of the _Radicle_,
and of the young Root from thence, is duly prepared therein, and with its
highest Tincture and Impregnation at last enriched.
The _Sap_ being thus prepared in the Lobes of the _Bean_, ’tis thence
discharg’d; and either into the _Plume_ or the _Radicle_, must forthwith
issue. And since the _Plume_ is a dependent on the _Radicle_; the _Sap_
therefore ought first to be dispenced to this; which accordingly is ever
found to shoot forth before the _Plume_, and that sometimes an inch or
two in length. Now because the primitive course of the _Sap_ into the
_Radicle_, is thus requisite, therefore by the frame of the Parts of
the _Bean_ is it made necessary too. For we may observe that the two
main Branches of the _Seminal Root_ in which the several _Ramifications_
in either Lobe are all united, commit not themselves into the _Seminal
Trunk_ of the _Plume_, nor yet so as to stand at right Angles with them,
and with equal respect towards them both; but being producted through
part of the _Parenchyma_ of the _Radicle_, are at last united therein to
the main Trunk, and make acute Angles therewith; as may be seen by _Fig.
2_. Now the _Sap_ being brought as far as the _Seminal Root_ in either
Lobe, and according to the conduct thereof continuing still to move,
it must needs immediately issue into the same part whereinto the main
Branches themselves do, that is, into the _Radicle_. By which _Sap_,
thus bringing the several Tinctures of the parts aforesaid with it, being
now fed; it is no longer a meer _Radicle_, but is made also _Seminal_,
and so becomes a perfect Root.
The _Radicle_ being thus impregnate and shot into a root, ’tis now time
for the _Plume_ to rouze out of its Cloysters, and germinate too: In
order whereto, ’tis now fed from the Root with laudable and sufficient
Aliment. For as the Supplies and motion of the _Sap_ were first made
from the Lobes towards the Root, so the Root being well shot into the
Moulds, and now receiving a new and more copious _Sap_ from these; the
motion hereof must needs be stronger, and by degrees revert the primitive
_Sap_, and so move in a contrary course, _sc._ from the Root towards the
_Plume_; and, by the continuation of the _Seminal trunk_, is directly
conducted thereinto; by which, being fed, it gradually enlarges and
displayes it self.
