ABLE STRUCTURE. 
outer Bark 3 2. an inner Rind; 3 a Blea ; 4. a Flefliy Subftance ; and 
3 a Pith. There is, indeed, between the Flefh and the Blea, 6. a V^afeu- 
iar Series ; and 7. Cones of Vefi'els take their courfe within the Fieth : 
thefe are properly as didinT parts as the five more obvious ones, and 
thefe are all. 
V/hatever part of the Plant we examine, we find thefe,. be it a Fibre, 
the Body of the Root, or the Stem. We never find more: and t'acing 
ihcfe thiUs feparatc from all other parts of the PIan^, we fee the other, or 
external portions, are only produdtions of them. All the imaginary 
complex ifradture of the Plant beyond this, vaniflies in an inftant, 
like thofe inchanted calllcs in romance, which when the talifman is broke, 
difippear. 'I he Root, its defeending Fibre, and the afeending Stalk, we 
tlius find are one, and not three fabdances: the fame feven parts com- 
pjfc them ; and they are continued from the one to the other,- or formed 
b/ the procefs of gn^wth. '1 his reduces the entire Vegetable to one bo- 
dy ; and what are fuppofed at its fummit to be many new and drange 
parts, are found to be no more than the natural extremities and termina- 
tions of the feven fubdances which form the entire body. Thefe external 
parts alfo are feven ; i the Cup j 2. the outer Petals; 3. the inner Petals ; 
4. the Ncfl.iria, either vlfibly didindt, or connedled in one thick ring; 
5. the Filaments ; 6. the receptacle of Seeds ; and 7. the Seed-Vefiels, 
or Seeds. Of thefe parts of a Flower five only are accounted generally; 
f )r it has not been obferved, that there is a didindtion of outer and inner 
Petals univerfally in Flowers; nor has it been remarked, that where there 
are not vifible Nedtaria, a thick and jointed cord always furrounds the bafe 
of the Receptacle. This will appear on more obfervation. The feven ex- 
terior parts never fail to be found the terminations only of the feven 
condituent fubdances of the Piant ; when the maceration is well managed. 
Tile Cup terminates the outer Bark, the inner Rind ends in the outer Pe- 
tals, the Blea form- the inner Petals, the Vafcular Series ends in the Nec- 
taria, and the Flefh in the Filaments; the Conic Cluders form the Recep- 
tacle, and the Pith furnidtes the Seeds and their Capfules. This is the ge- 
neral condrudtion of a Vegetable Body; it will be illudirated in the fuc- 
ceeding chapters, by particular indances, but here the entire view of the 
fubjedl was necefiTary. We fee by it, that thefe fourteen parts, feemingly 
fo different, are reduced to feven : and we fhall fee thefe are univerfal in 
Plants ; tho’ their courfe be lefs plain in fome, and their terminations lefs 
didindt in others. As to colour, we fhall find that accidental, the fame 
outer Rind is Brown in the Root, green on the Stalk, and Red in the Cup 
perhaps ;
