VEGETABLE STRUCTURE.

The Neck, or part between the Root and Stalk, has the form of a 
fmall ring ; and feems to divide them one from the other. The Stalk, on 
a flight view, might feem rather fixed upon the Root than rifing from it : 
but the Microfcope flaews the wonderful mechanilm, and it is this. 
The outer Bark, the fpungy inner Rind, and the Blea, all run up in a 
continued line from the Root : but the FlelE, at the union of the Root 
and Stalk, forms an arch : from which rifes a procefs or part of the fur- 
face, forming the Flelli of the Stalk j which foon gets thufe coverings as 
it rifes. 
Thus is the Stalk continued from the Root, and is truly a lengthened 
Procefs of that part, extended upwards. When the force of the Root 
ceafes, at a certain appointed height, being the utmolf the circulatory fy- 
dem of the Root can effecl, a fecond fydem is formed ; and when a new 
Stalk is forced up from this, as the firft was from the Root, and has reach- 
ed its utmoll: heighth, the parts open into a Flower. The three outer Pe- 
tals, "yi are formed of the exterior Rind of the Stalk ; the inner Bark forms 
the three innermod Petals, g, and there terminates : the Valcular Series 
terminates in a thick Ring, h : the Flediy Subdance forms the Antherae, 
i : the Conic Cluders make a Receptacle, k ; and the central Pith forms 
the Seeds. So ends the Stalk ; and thefe Seeds ripening, produce new 
Plants : only continuing to grow. 
The elTential part to a Plant is in this, as in all others, the Flediy Sub- 
dance of the Stalk : and a piece of this is lodged in every globule of Fa- 
rina ; which being dickered from danger in the Seed, afterwards grows. 
Of this we have already treated at large: it is the Root we are properly 
examining here. While the principal part, or main body, of this Root, 
is thus continued upward in a Stalk for flowering, the Flediy Subdaiice, 
furnilhed with abundant nouridiiiient for the growth of the Stem, fwelis 
out alfo a little on one flde, near the Joint, where the Root ends and the 
Stalk begins. The time of this fweliing is jud when the Flowerdalk is 
rifing; and its fird appearance is a yellowish Knob or Lump, vlfible only 
by the Microfcope. 
The origin of this is jud fuch a Particle as that which is to be afer- 
wards lodged in each grain of the Farina, and thence delivered to the 
Seed ; and hwing the fame vegetative power, or Principle of Life with 
that, it grows in the fame manner. It is already in the ground ; it is as 
fecurely bedded in the body of the Root, as the other can be in the Seed ; 
and having an immediate fupply of nouridiment from the very Fibres of 
the Plant, it diredly grows.
