dual, that force is fuch likewife ; not to caufe the leaft breach of its

heir Germen being prolonged, and fo difplaying its feveral parts, as when

contriv'd, is its due nutrition alfo. - For being originated from the 
inner part of the Lignous Body, ‘tis nourifhed with the belt fermented 
Sap in the Trunk, fe. that next adjacent to it in the Pith. Befides, 
finceall its Parts,upon their fhooting forth, divaricate from their per- 
pendicular, to a croß Line, as thefe and the other grow and thrive 
together, they bind and throng each other into a Kwot: through 
which Kot the Sap being ftrain’d, ’tis thus, in due moderation and 
purity delivered up into the Branche;

only where collaterl Brazches put forth 3 but in fuch Plants alfo, as 
fhoot up in one fingle Trunk 5 as in Corm. Wherein, as they make
