SECTION I.. 
ULTIMATE ANATOMY OF .VEGETABLES. 
_ 36. VecETaBLEs are composed of solids and fluids. The 
former give firmmess and stability to the vegetable frame ;— 
according to their mode of arrangement, determine the pe- 
~ culiar structure and form of the plant ; contain and circulate 
the vegetable juices ; and deposit them in their proper places. 
The fluids support the life, and continue the growth of the 
vegetable, by supplying it with nutritious matter. This 
matter is modified, and deposited in appropriate situations 
by the previously existing solids, excited to action by pecu- 
iar stimuli, and regulated by the vital principle ; and thus 
successively the various amie — : 
constitute the

= taken, when minutely examined, is found to consist of an as- 
ssemblage of very small cavities, bounded by an extremely de- 
licate film or layer of vegetable matter, termed Memsrane. 
The whole plant consists of a tissue of such cavities, varying 
in form from 4 sphere to an elongated tube, and frequently 
having an extremely slender vegetable Frere crossing or 
wound round the sides of the cavity. In dissecting any 
part of a plant, we can proceed no further in the separation 
of parts; and, accordingly, memBRANE and FIBRE are th 
last (or ultimate) structural constituents of the Madea ;
