The Contexture hereof is, in many of its parts, much more close than that of the _Cortical_; and their Pores very different: For whereas those of the _Cortical_ are infinitely numerous, these of the _Lignous_ are in comparison, nothing so. But these, although fewer, yet are they many of them more open, fair, and visible: as in a very thin Slice cut athwart the young Root of a Tree, and held up against the Light, is apparent: Yet not in all equally, in _Coran_-Tree, in _Goosberry_-Tree, _&c._ less; in _Oak_, _Plums_, and especially _Damascens_, more; in _Elder_, _Vines_, &c. more conspicuous. And as they are different in number and size, so also (whereon the numerousness of the Pores of the _Cortical Body_ principally depends) in their shape. For whereas those of the _Cortical Body_ are extended much alike both by the length and breadth of the _Root_; these of the _Lignous_ are only by the length; which, especially in _Vines_ and some other _Roots_, is evident. Of these Pores, ’tis also observable, that although in all places of the _Root_ they are visible, yet most fair and open about the _Fibrous Extremities_ of some _Roots_ (and in many _Roots_ higher) where there is no Pith. These Pores, as they shew in young _Roots_ of Trees, see in _Fig. 6_, & _7_. This _Lignous Body_ lieth with all its Parts, so far as they are visible, in a Circle or Ring; yet are there divers extream small Fibres thence shooting, usually mixed with the _Cortical Body_; and by the somewhat different colour of the said _Cortical Body_ where they stand, may be noted these Fibres; the _Cortical Body_ and _Skin_ all together, properly make the _Barque_. The proportion betwixt this _Lignous Body_ and the _Cortical_, is various, as was said; yet in this, constant, _sc._ that in the fibrous, and smaller Parts of the _Root_, the _Lignous Body_ is not only in compass, but in quantity the less; running like a slender Wyer or Nerve through the other surrounding it. They stand both together pyramidally, which is most common to _Infant-Roots_, but also to many other. The next Part observable in the _Root_, is the _Insertment_. The existence hereof, so far as we can yet observe, is sometimes in the _Radicle_ of the Seed it self; I cannot say alwayes. As to its substantial nature, we are more certain; that it is the same with that of the _Parenchyma_ of the _Radicle_; being alwayes at least augmented, and so, in part, originated from the _Cortical Body_, and so, at second hand, from the said _Parenchyma_: For in dissecting a _Root_, we find, that the _Cortical Body_ doth not only environ the _Lignous_, but is also wedg’d, and in many pieces inserted into it; and that the said inserted pieces, make not a meer Indenture, but transmit and shoot themselves quite through as far as the Pith; which in a thin Slice cut athwart the _Root_ as so many lines drawn from the Circumference towards the Center, shew themselves. See _Fig. 6_, & _7_.
