Betwixt which Part ments, theCortical Body, being bound in on the one hand, bythe furrounding Skiz and Moulds, and prefled upon by the Lignous on the other, mutt needs infert it felf and fo move contraryto it, fromthe Circumference towards the Center. Where the {aid contrary motions continued as begun, theyat laft meet, unite, and either make or augment the Pith.

ONE true ufe of the Pithis for the better Advancement of the Sep, whereof I (hall {peak in the next Chapter. The ufe I here obferve, is for th € quicker and higher Fermentation of the Sap: For although the Fermentation made in the Cortical Body waswell fubfervient to the firlt Vegetations, yet thofe more perfect ones in the Trunk which after follow, require a Body more adapted to it, andthat isthe Pith 5 which is & neceflary, as not to be only common to, but confiderably large inthe Roots of mott Plants; if not in their inferiour parts, of Plants, parts, yetat their tops. Where from the Cortical Body, yet bein thougheither deriv’d or amplify’d g byits Infertions only, we mayt herefore fuppofe, as tho, fo this, to be more finely conftituted. being alfo from its coarétatio And n, while inferted, nowfree 5 all its Pore upon the fupply of the Sup, will more or lefs be amplified : Upos, which accounts, the Sap ther n einto received, will be more pure its fermentation therein more active.
