the Cortical Body, which are extended by the length and breadth much 
alikes and from thofe of the Liguows, being only by its length. 
12. g. The number-and fize of thefe Infertions are various. In 
Hamthorw, and fome others, and efpecially Willows, they are moft. ex- eek 
tream {mall 5 in Cherries and Plums they are Bigers and in the Vine ath 
and fome other Trees, very fairly apparent. In the Roots of mo” ~* 
Herbs they are generally more ealily difcoverable ; which may lead to 
the obfervation of them in all. 
13.-§. Thefe Infertions, although they are continuous through 
both the length and breadth ofthe Root yet not fo in all Parts, but 
by the feveral fhootings of the Ligvows Body they are frequently in- 
tercepted. For of the Lignows Body it is (here beft) obfervable 5 
That its feveral Shootings, betwixt which the Cortical isinferted, are 
not, throughout the Root, wholly diftinG, ftrait and parallel: but 
that all along being enarch’d, the Lignows Body, both in length and 
breadth, is thus difpofed into Braces or Ofewlations. Betwixt thefe 
feveral Shootings of the Lignous Body thus ofculared, the Cortical Tab. 2. f° 3: 
fheoting, and being alfo ofculated anfwerably Brace for Brace, that 
which I call the Ixfertment is framed thereof. 
14, §, Thefe Ofeulations are fo made, that the Pores or Fibres of 
the Lignows Body, I think, notwithftanding, feldom or never run one 
into another; being, though contiguous, yet fill diftin®. In 
the fame manner as fome of the Nerves, though they meet, and for 
fome fpace are aflociated together, yet ‘tis moft probable, that none 
of their F7bres are truly inofculated, faving perhaps, in the Plexures. 
15. §. Thefe Ofculations of the Lignous Body, and fo the intercep- 
tion of the Infertioys of the-Cortical, are not to be obferv'd by the 
traverfe cut of the Root, but by taking off the Barque. In the 
Roots of Trees, they are generally obfeure; but in Herbs often more 
diftin&y apparent; and efpecially in a Turzep: the appearance where- 
of, the Barque being ftripp’d off, is asa piece of clofe-wrought Net- 
work, fill’d up with the Infertions from thence: 
16. §. Thenext and laft diftin® part of the Root is the Pith. The 
fubftantial nature thereof, is, as was {aid of the Infertment, the fame 
likewife with that of the Pareschyma of the seed. And according to 
the beft obfervation I have yet made, “tis fometimes exiftent in its Ra- 
dicle 5 in which, the two main Branches of the Lobes both meeting, 
and being ofculated together, are thus difpos'd into one round and 
tubular Trak, and fo environing part of the Parenchywa, make there- 
ofa Pith; asin either the Redicle, or the young Root of the great Bear 
or Lupine, may, think, be well feen. 
17. §. Butmany timesthe Original hereof is immediately from 
the Barque. For in diffeGion of divers Roots, both of 2rees and Herbs, 
as of Barberry or Malloms, it is obfervable, That the Cortical Body and 
Pith, are both of them participant of the fame Colour 3 in the Barberry, 
both of them tinged yellow, and in Malows, green. -In cutting the 
fmaller Parts of the Roots of many Plants, as of Borage, Mallows, Par- 
fey, Columbine, Gc, “tis alfo- evident, That the Lignans Body is not 
there, inthe leaft Concave, but {tandeth Solid, or without any Pith, Tabb f.g-3 
inthe Center 3 and that the Infertions being gradually multiplied after- 
wards, the Pith, at length, towards the thicker parts of the Root, 
fhews and enlarges it felf Whence it appears; that in alldirch Roots;
