 parts in a more advanced state ; one seed being nearly ripe, supported by its 

 elongated and thickened umbilical cord ; a second ovulum considerably in- 

 creased in size, but abortive ; and the remains of the ruptured ovarium — some- 

 what enlarged. 



Cand 2). — Two longitudinal sections of the nearly ripe seed; exhibiting 

 the vascular cord continued from the axis of the funiculus umbilicalis to the 

 apex of the seed ; tlie remarkable process of the inner integument at the 

 umbilicus (of which another view is given separately at E) ; and the unripe 

 embryo nearly in contact with this process, and as yet undivided.
