VEGETABLE STRUCTURE.

it fo much farther, that we may diftinguifli it as divided into parts 3 and 
from this time new Leaves, peculiar to the Plant, are formed daily ; and 
it afiumes its proper form. 
To underftand the progrefs, we mufl: begin with the difiecflion of the 
Bud in the perfecfl Seedling ; fooner than that It difclofes nothing diftindt- 
ly; but at that period we begin to fee its conftrutflion, which becomes 
more evident from time to time afterwards. We fee, in Fig. 49, the 
manner wherein the Bud rifes from the head of the Root ; and if we cut 
a thin flice lengthwife from this fedtion, and apply more power of magni- 
fying, it appears as at Figure 57. The Flefli of the Root returns in an 
irregular arch at ^ ; at c ^ rife the two portions of it fideways, which run 
into the Footflalks of the Leaves ; and at from the very center, afeends 
the little Bud. It is a hollow cone, formed of the Flefh of the Plant, 
arifing from the mafs of Flefh e, and is already filled with a fair Pith in 
large proportion. This Pith has plainly rifen from the upper furfaceof the 
mafs of Flefli within the outline of the Cone ; and its early appearance in 
this place confirms the opinion, that wherever the Flefli of a Plant forms 
a cavity, a Pith is produced to fill it. 
A SECTION of the Bud, altogether feparated from the reft of the Plant, 
is fhewn at Fig, 58. To illuftrate this conftrudlion. In this Figure, a re- 
prefents the Pith, over which lies the cone of Flefh 1 ;. On the furface of 
this we fee a Line, c, fcarce diftinguifliable, which is the fedlion of the 
Vafcular Series : above this comes a large Blea, d ; and on the outfide of 
this appear the two Rinds, f g. Thus is there lodged upon the crown of 
the Root, the Bud of a future Plant, which has yet only a fhort rudiment 
of a Stalk, h, to fupport it ; and is cloathed, as it were, in fo many fliells 
by its feveral outer Membranes. This we are to trace in its growth, into 
an entire Plant : but we are firft to confider the origin of thofe Leaves 
which rife from the Root next after the Seed-Leaves themfelves, and which 
fupply their office in a larger way when they are faded. Thefe are not 
produced together with the Bud. We may be fure of this by the preceed- 
ing obfervation ; for we fee the Bud when the young Leaves are feparated 
from it, abfolutely naked. What is figured at 58 is the rudiment of a 
Stalk, and nothing more. Nor are even the two Leaves which defend it 
formed of any part of its fubfiance. There are eight or ten following 
thefe j and if they were in fmall upon the Bud itfelf, we fliould, by the 
power of Microfeopes, diftinguifti them : but it is not fo. They are pro- 
duced afterwards from the furface of that very fhort rudiment of a Stalk
