This analogy between the vegetable and animal fetus in refped to 

 their produaion, nouiifliment, and oxygenation, is as forcible in fo 

 obfcure a fubjed, as it is curious ; and may in large buds, as of the 

 borfe-chefnut, be almoft feen by the naked eye. If with a penknife 

 the remaining rudiment of the laft year's leaf, and of the new bud in 

 its bofom, be cut away llice by flice, the feven ribs of the laft year's 

 leaf will be feen to have arifen from the pith in feven diflincSt points, 

 making a curve; and the new bud to have been produced in their 

 center, and to have pierced the alburnum and bark, and o-rown with- 

 out the affiftance of a mother. 



And laftly, by in part 



d 



in part tearing, the pith and 



alburnum from the bottom of a new leaf-flalk of horfe-chefnut about 



the middle of May 



prominence may be feen in th 



part of the leaf-ftalk, which fills up a fpace between the veflels of 

 the bottom of the leaf-ftalk and thofe of the new bud, and feems to 



d them by its extremities, and to prefs on the pith beneath 



From this apparent 



d I conjedure that the now 



living fibres, 

 animalcules, are probably fecreted, which form the new bud adh 



or 



o 



the pith, and nourifhed by the parent leaf; that thus a paternal 



progeny is produced without the affiftance of a mother. 



3. This paternal offspring of vegetables in their buds and bulb 



ded with a very 



circumftance : and that is. th 



exadly refemble their parents, as is obfervable in grafting fru 



they

plants, be 



/=» 



wh 



rated by two parent 



th 



and 



nutriment by the mother, is liable to perpetual 



feminal ofi^spring of 

 tainly fupplied with 

 ariation. This alfo 



the vegetable clafs dicecia, where the male flowers are produced 



and the females on another, the buds of the 



formly produce either male flowers 



ther buds fim 



them 



felves; and the buds of the female trees either produce female flowers, 

 or other buds fimilar to themfelves ; whereas the feeds of thefe trees 

 ^produce either male or female plants. See Sed.*IIL 2. i.
