Thus the Flefli makes its regular courfe in its lengthened annular form 
along the Root, and only from its furface gives thefe parts which are to 
appear above the ground; the Flefh of the Bud upwards, and that portion 
of Flefli which is allotted to the Seminal Leaves lideways. 
W E are now to examine the proportions of the feveral parts in the 
Footfialks of the Seed-Leaves by tranfver e fedions. TTe flattened, hol- 
lowed form of the Footftalk makes a tranfverfe fedion of it appear fome- 
what in the form of a Crefcent. The outer Rind, which vvjs red in the 
Root, continues its colour alfo in this part, and even the Vefl'els of the 
Blea have a red liquor. This diflinguiflies excellently the Veflels of that 
part from the Cells which they form, and which feme have taken for 
VelTels ; the fluid in thofe cells being colourlefs, while this is red. 
We have had occafion to remark a fwelling of the head of the Root, 
at the point this is owing to the fwoln date of the Flelh in that part, 
which forces out all the others it is here a portion from the furface oF 
the Flefli is fent up into the Footflalks of the Seed-Leaves, and this at its 
very origination in quality of the Flefli of the Footflalk, divides into three 
regular portions : each of thefe forms an inverted arch upon the furface of 
the fwelled part, and rlfes hollow into the Footflalk. 
Thus are formed three tubes, as it were, of the Flefli of the Plant, 
conneded intimately with that of the Root, but whofe hollows do not 
open into it. Thefe fiefliy bodies divide themfelves to a diflance, one run- 
ning up the center, and the other two near the two horns of the Crefcent : 
they are not furrounded with a Vafcular Series as the Flefli of the Root, 
and Flowering Stalks of Plants, nor have they any Pith within ; but each 
of thefe tubes gives origin to two Conic Clufters of Veflels, which run up 
within it to the Leaf : each of the fide ones again dividing toward the Leaf 
fo as to form four. A fedion cut tranfverfely, and with due care, from 
the furface of the fwelling at the head of the thick part of the Flefli, 
fliews this diflindly : fuch a fedion is reprefented at Figure 50. The dif- 
pofition of the three tubes of Flefli, and of the two Conic Clufters of 
Veflels in each tube, are reprefented at 51 — a, as they appear in a very 
thin fedion of the Footflalk of a Seed-Leaf, near the bafe j and in another 
fedion taken near the Leaf, at 51 — b. 
Thus the law of Nature, in the origination of the Conic Clufters, is 
invariable. As there are fix in a Fibre, and twelve in the body of a Root 
in Hellebore ; fo there are fix only in the body of the young Root of Ra- 
difli, and ten in each of the Foetflalks of Seed-Leaves, that rife from it j 
and in neither cafe do the greater number above take their origin from
