By what hath been said, that the _Parenchyma_ is not the only
constituting Part, besides the Cuticle, is imply’d: there being another
Body, of an essentially different substance, embosom’d herein: which may
be found, not only in the _Radicle_ and _Plume_, but also in the Lobes
themselves, and so in the whole Bean. See _Fig. 2_.
This inner Body appears most plain and conspicuous in cutting the
_Radicle_ athwart, and so proceeding by degrees towards the _Plume_,
through both which it runneth in a large and straight Trunk. In the
Lobes, being it is there in so very small proportion, ’tis difficultly
seen, especially towards their Verges: yet if with a sharp Knife you
smoothly cut the Lobes of the Bean athwart, divers small Specks, of a
different colour from that of the _Parenchyma_, standing therein all
along in a Line, may be observ’d; which Specks are the Terminations of
the Branches of this inner Body. See _Fig. 3_.
For this inner Body, as it is existent in every Organical part of the
Bean, so is it, with respect to each part, most regularly distributed.
In a good part of the _Radicle_ ’tis one entire Trunk; towards the
Basis thereof, ’tis divided into three main Branches; the middlemost
runneth directly into the Plume; the other two on either side it, after
a little space, pass into the Lobes; where the said Branches dividing
themselves into other smaller; and those into more, and smaller again,
are terminated towards the Verges of each Lobe; in which manner the said
inner Body being distributed, it becomes in each Lobe, a true and perfect
Root. See _Fig. 2_.
This Seminal Root, as now we’ll call it, being so tender, cannot be
perfectly excarnated, as may the Vessels in the Parts of an Animal, by
the most accurate Hand; yet by dissection begun and continu’d, as is
above-declared, its whole frame and distribution may be easily observ’d.
Again, if you take the Lobe of a Bean, and lengthwise pare off its
_Parenchyma_ by degrees, and in very thin Shives, many Branches of the
Seminal Root, (which by the other way of Dissection were only noted by so
many Specks) both as they are fewer about the Basis of the Bean, and more
numerous towards its Verges, in some good distinction and entireness will
appear. For this you must have new Beans.
As the inner Body is branched out in the Lobes, so is it in the _Plume_:
For if you cut the _Plume_ athwart, and from the Basis proceed along
the Body thereof, you’l find therein, first, one large Trunk or Branch,
and after four or five very small Specks round about it, which are the
terminations of so many lesser Branches therewith distributed to the
several parts of the _Plume_. See _Fig. 4_. The distribution of the
inner Body, as it is continuous throughout all the Organical Parts of the
Bean, is represented by _Fig. 2_.
