and that a new embryon is inftantly produced by their recipro- 

 cal embrace and coalefcence. 



And that parts of this new organization afterwards acquire 

 new appetencies, and form new molecules, and thus gradually 

 produce other parts of the growing feed, which do not at firft 

 appear, as the plumula, radicles, cuticle, and the glands of re- 

 production in the pericarp and anthers, which correfpond in 

 the animal fetus to the lungs, inteftines, cuticle, and the organs, 

 which diftinguifh the fexes, and are their parts of fecondary 

 formation, 



If fecondary parts of a vegetable embryon were not fabrica- 

 ted from the primary parts, or firft rudiments of it, the flowers 

 of the clafh dicecia of Linnxus could nor produce both male 

 and female feeds, as the male and female organs of reproduction 

 refide on different plants. For as the male plants produce buds 

 fimilar to thcmielvcs, which may be termed male buds ; and 

 the female plants produce buds fimilar to themfelves, which 

 may be termed female buds, it would feem impoflible for the 

 flowers to generate female feeJs according to the theory of re- 

 production above delivered. As the male, not being an her- 

 maphrodite, cannot be fuppofed to fecrete any fibrils with ap- 

 petencies proper to produce female organs, as no fach can ex- 

 id in his blood, which mult therefore be fabricated afterwards 

 by the new appetencies acquired by the new organizations of 

 the growing embryon. 



n. From this new doctrine of a three-fold vegetable mule 

 by lateral propagation, as the new bud of a tree, which has had 

 two fcions ingrafted on it one above another ; in which it is in- 

 conteftibly (hewn, that different fibrils or molecules are detach- 

 ed from different parts of the parent caudex to form the filial 

 one, which adheres to it ; we may fafely conclude, as it is de- 

 ducible from the ftrongeft analogy, that in the production of 

 fexual mules, foine parts of the new embryon were produced 

 by, or detached from, fimilar parts of the parent, which they 

 refemble. And that as thefe fibrils or molecules floated in the 

 circulating blood of the parents, they were collected feparately 

 by appropriated glands of the male or female j and that fi- 

 nally on their mixture in the matrix the new embryon was gen- 

 erated, refembling in fome parts the form of the father, and in 

 other parts the form of the mother, according to the quantity 

 or adivity of the fibrils or molecules at the time of their con- 

 junction 



And laftly, that various parts of the new organizations after- 

 wards acquired new appetencies, and formed molecules with 

 new propenfitiesj and thus gradually produced other fecondary
