CHAP. Il 
Of the TRUNK. 
LB» SV ING thus declar’d the degrees of Vegetation 
in the Root ; the continuance hereof in the Trunk 
fhall next be. fhew’d: in order to which, the 
Parts. whereof this likewife is compounded, we 
{hall firft obferve. 
Y 1. §. . That which without diffeCtion fhews it 
felf, is the Coardure: 1 cannot fay of the Root, 
3 but what I choofé here to mention, as {tanding 
betwixt them, and fo being common to them both; all their Parts 
being here bound in clofer together, asin the tops of the grown Roots 
of very many Plants, isapparent. | 
2. §. Ofthe Parts of the Trunk, the firft occurring is its Skiz : 
The Formation whereof, is not from the Air, but in the Seed, from 
whence it is originated; being the production of the Cvficle, there 
invefting the two Lobes and Plume, ; 
3. g. The next Part is the Cortical Body; which here in. the 
Trunk is no new fabftantial Formation; but, as is that of the Root, 
originated from the Parenchyma of the Plume in the Seed 5 and isonly 
the increafe and augmentation thereof, The shiv, this Cortical Body Tab.3. f. 1, 
ar Parenchyma, and (for the moft part ) fome Fibers of the Ligzons Cas 
mixedherewith, alltogether make the Barque. 
4. §. Next, the Lignzous Body, which, whether it be vifibly di- 
vided into many fofter Fibers or fmall Threads, asin the Bean, Fem 7,» He fait 
nel, and moft Herbs; or that its Parts {tand more compact and clofe, ; 
fhewing one hard, firm and {olid piece, as in Trees 5 it is, in all, one 
and the fame Body;, and that not formed originally in the Trunk, 
but in the Seed; being nothing elfe but the prolongation of the Se- 
minal Root diftributed in the Lobes and Plume thereof. : 
5. g. Laftly, The Ixfertions and Pith are here originated like- 
wife from the Plume, asthe fame in the Root, from the Radicle: So 
that astotheir Subftantial Parts, the Lobes of the seed, the Redicle 
and Plume, the Root and Truk are all one. ; 
6. §. Yet fome things are more fairly obfervable in the Trak, 
Pirft, the Latitudinal thootings of the Lignons Body, which in Trunks 
of feveral years growth, are apparent in fo many Rings, as is common- 
ly known: For feveral young Fibers of the Lignous Body, as in the Tab 3. f. 5 
ony fo here, fhooting in the Cortical one year, and the {paces be- & 8. 
twixt.them being after fill’d up with more (I think not till) the 
next, at length they become altogether a firm compact Rings the 
Perfettion of one Ring, and the Ground-work of another, being thus 
ade concomitantly.
