But many times the Original hereof is immediately from the _Cortical Body_. For in dissection of divers _Roots_ both of Trees and Plants, as of _Barberry_ or _Mallows_, it is observable, that the _Cortical Body_ and _Pith_ are both of them participant of the same Colour; in the _Barberry_ both of them tinged yellow, and in _Mallows_ green. In cutting the smaller Parts of the Roots of many Plants, as of _Borage_, _Mallows_, _Parsley_, _Columbine_, &c. ’tis also evident, that the _Lignous Body_ is not there in the least Concave, but standeth perfectly in the Center; and that the Insertions being gradually multiplied afterwards, the _Pith_ at length, towards the thicker parts of the _Root_, shews and enlarges it self. Whence it appears, that in all such _Roots_, the _Pith_ is not only of the same substantial nature, and by the Insertions doth communicate with the _Cortical Body_; and that it is also more or less augmented by it; which is true of the _Pith_ of all _Roots_; but is moreover, by mediation of the said Insertions, wholly originated from it. The various appearances of the _Insertions_ and _Pith_ from the Fibrous Parts to the top of the _Root_, see in _Fig. 9_, _10_, _11_, _12_, _13_, _14_. The Pores of the _Lignous Body_, entire in the said Fibrous Parts, are best seen when they have lain by a night dry, after cutting. A farther evidence hereof are the Proportions betwixt the _Cortical Body_ and _Pith_. For as about the inferiour Parts of the _Root_, where the _Pith_ is small, the _Cortical Body_ is proportionably great; so about the top, where the _Pith_ is enlarged, the _Cortical Body_ groweth proportionably less, _sc._ because by its Insertions, ’tis gradually bestowed into the _Pith_. Likewise the peculiar frame of some _Roots_, wherein besides the _Pith_, the _Lignous Body_ being divided into a double Ring, there is also a thick Ring, of a white and soft substance, stands betwixt them; and is nothing else but the Insertions of the _Cortical Body_ collected into the said Ring; but, towards the top of the Root, being inserted again, thus maketh a large and ample _Pith_; as in _Fennel_-Roots is seen. The Pores of the _Pith_, as those of the _Cortical Body_, are extended both by the breadth and length of the _Root_, much alike; yet are they more or less of a greater size than those of the _Cortical Body_. The Proportions of the _Pith_, are various; in Trees, but small; in Plants generally, very fair; in some making by far the greatest part of the _Root_; as in a _Turnep_: By reason of the wide circumference whereof, and so the finer Concoction and Assimilation of its Sap; that part which in most old Trunks is a dry and harsh _Pith_, here proves a tender pleasant meat. The parts of a _Turnep_ in the travers cut see in _Fig. 8_.
