SE ARAARESRAET SS TEE Ss coll dbase sae a 
Cuticle, Which tranfient sap, though it thus becomes fine, yet is not 
fimple 5 but a mixture of Particles, both in refpect of thofe originally 
in the Root, andamongft themfelves, fomewhat heterogeneous. And 
being lodg’d in the Cortical Body moderately laxe, and of a Cir- 
cular form 5 the effect will be an eafie Fermentation. The Sap fermen: 
ting, a feparation of Parts will follow ; fome whereof will be impatt- 
ed tothe Circumference of the Cortical Body, whence the Cuticle be- 
comes a Skin 3 as we fee in the growing of the Coats of Cheefes, of 
the Skin over divers Liquors, and the like. Whereupon the Sap 
pafling into the Cortical Body, through this, as through a Manica Hip- 
pocratis, is {till more finely filtred. With which Sap, the Cortical 
Body being dilated as far as its Tone, without a folution of Continu- 
ity, will bears and the fupply ofthe sap ftill renew’d : the pureft part, 
as moft aptand ready, recedes, with its due Tinures, from the faid 
Cortical Body, toallthe parts of the Ligvous; both thofe mixed with 
the Bargue, and thofe lying within it. Which Ligrons Body like- 
wife fuper-inducing its own proper Tindfures into the faid Sap 5 “tis 
now to its higheft preparaton wrought up, and becomes (as they fpeak 
of that of an Animal) the Vegetative Ros or Cambinm : the noblett 
part whereof is at laftcoagulated in, and affimilated to the like fub- 
{tance with the faid Lignous Body. The remainder, though not united 
to it, yet tinctur'd therein, thus retreats, that is, by the continual 
appulfe of the Sap, is in part carried off into the Cortical Body back 
again, the Sep whereof it now tinétures into good Aliment. So 
that whereas before, the Cortical Body was only relaxed in its Parts,and 
fo dilated ; *tisnow increas‘d in real quantity or number of parts, and 
fo is truly nourifh'd. And the Cortical Body being faturate with fo 
much ofthis Vital sap as fervesit felf; and the fecond Remainders 
difcharged thence to the Skiz 3 this alfo is nourifh’d and augmented 
therewith. So that asin an Avimal Body there is no inftauration or 
growth of Parts made by the Blond only, but the Nervous Spirit is al- 
fo thereunto affiftants fois it here: the sap prepared in the Cortical 
Body, is as the Bloud,and that part thereof prepared by the Ligzous, is 
as the Nervous Spirit ; which partly becoming Nutriment to it felf} 
and partly being difcharged back into the Cortical Body, and diffufing 
its Tin@ure through the Sap there, that to the {aid Cortical Body and 
Skiz, becomes alfo true Nutriment, and fo they all now grow. 
24. §. In which growth, a proportion in length and breadth is ree 
quifite: which being rated by the benefit of the Plant, both for firm 
ftanding and fuffictent Sap, muft therefore principally be in length, 
And becaufe it is thus requifite, therefore by the conftitution of one 
of its Parts, (7. the Lignous Body, it is alfo made neceffary. For the 
Pores hereof, inthat they are all extended by its length, the Sup alfo 
according to the frame and fite of the faid Pores will principally move; 
and that way asits Sap moves, the fame way will the generation of its 
Parts alfo proceed 5 /é. by itslength. And the Lignous Body firft (that 
is by a priority caufal) moving in lengthit felf; the Cortical alfo moves 
therewith. For that which is nourifh’d, is extended: but whatever 
is extended, is mov'd : that therefore which is nourifh’d, is mov’d: 
The Lignous Body then being firft nourith’d, ‘tis likewife firft miov'd, 
and fobecomes and carries in it the Principle of all Vegetative motion 
in the Cortical ; and {0 they both move in length:
