tinct: its adhesion is very slight. At a late period the upper 
portion of the testa is much thinner, and is lined by the nu- 
cleus, which is very thin. "The corresponding portion of the 
embryonary sac is occupied by the albumen, which is globu- 
lar and dense: the lower portion being still unoccupied. 
The embryo is fully developed, and the lateral slit, and en- 
closed plumule visible.

b. Apex of outer coat cut away. 
c. Rather earlier than the above, but from the same spadix. 
d. After fecundation, and fall of upper portion of spadix. 
e. Ditto apex slightly magnified. 
f. Embryonary sac removed.

The ovary must be examined very early, and before the 
flower is a line long in order to detect the ovule in its first 
stage. In this it is an oblong cellular grumous body, pendent 
from near the top of the ovary, but more decidedly related to 
one stigma than to the two. 
In the next stage it will be found to be annuliform about 
the middle, or this part will be found thickened into a sort 
of margin. 
In the next, (but which takes place sometime after the 
nucleus is nearly concealed by the coat that has grown up -
