 of the fucceffive production of leaf-buds and leaf-bulbs previous to th 

 produdion of flovver-buds or flower-bulbs is wonderfully analoo-ou 

 to the generation of the aphis, which rifing from an eg^ in the fpr

 males and females is produced, and eggs are laid in the autumn from 

 their amatorial intercourfe. Encycloped. Britan. Amoenitat. Academ.

 from the egg requires to be reproduced many times by folitary pro- 

 pagation before it becomes fufficiently perfed to generate a fexual 



offspring like the buds and bulbs from feeds above mentioned, 

 it is probable, that the polypus of our ftagnant waters, which
