many portions. This flefliy fubftance is every where at an equal dif- 
tance from the hurface, rounding the bafe in form of an arch or fliell ; 
and what may appear more ftrange, but is equally certain, purfuing its 
courfe in the fame vaulted form at the top of the Root, i6, b. and under 
all the Fibres, i6, b. Tho’ it fends out a part of its uter fiibftance into 
them. 
Thus terminates the Pith, the conic Clufters, and the Flefh, forming 
arches within the common coats, and returning upon themfelves ; but it is 
not fo with the other parts. Next above the Flefli appears the Vafcular 
Scries, i6. 4. tho’ very indiftindfly in the longitudinal fedion : and over 
thefe lies a thick white Blea, 5. This is continued in an arch round the 
bafe of the PvOor, but it has no fuch termination at the head, 16, d, for 
there it runs up into the Stalk, making the fame third part in its fubftance. 
Ni;xt above this we find the inner Rind of the Root, 6. This is of 
an uncommon thicknefs, and is pellucid, and almofi: colourlefs, or of a 
very faint greenifii white. This makes the gelatinous part of the heads of 
file Fibres, and is nearly of the fame fubftance here. 
Over this is carried the outer Rind, 7. which is brown and thin. Thefe 
are all the conftituent parts of the body of the Root : of which the three 
innermoft alone are peculiar in a manner to it. The reft are continuations 
of the fame parts in the Fibres, and are continued alfo into the Stalks. 
CHAP. XI. 
Of the Insertion of the Fibres at the Body of the Root. 
T H E body of the Root is the original part produced from the Seed of 
the Plant. It is, indeed, the Corculum or Heart of the Seed fwell- 
ed and enlarged into that form ; and the Fibres as well as Shoots for Leaves 
and Flowers are all produced from it. The Flefli in the Stalk of the ori- 
ginal or parent Plant, furniflied that Heart of the Seed j and this flefliy 
fubftance of the Root is the fame thing fwelled to a larger bulk. Its Pith 
has been thrown out from its own Veftels inward ; and the feveral Coats 
externally have been produced in the fame manner by its extravafated Juices 
hardened into a fubftance; and by continuations of thofe Veflels them- 
felves in flender branches into it. Thus the fiefliy fubftance in the body
