REPRODUCTION

a confequent femihal progeny. 



As the progeny by lateral generation fo exadly refembles the parent 

 flock, it follows, that though any new variety, or improvement, may 

 be thus continued for a century or two, as in grafted fruit-trees, yet 

 that no new variety or improvement can he obtained by this mode 

 of generation ; though fome hereditary difeafes, as the canker, are 

 believed to arife in ingrafted trees, which have long been propagated 

 by lateral generation, as 



plained in No. i. 3. of this Sed 



But from the fexual, or amatorial, generation of plan 



ties, 01

as many of th 



young plants from feeds are diffimilar to the parent, and fome of them

 alternately J and when the feed-pods were perfedly formed, I cut! 

 down the purple, and left the other for feed. This had the defired
