linear relations with the columnar central tissue, and that the 
tube is a subsequent formation being developed from the 
base of the mass, and running along between the column 
and that space of the ovulum next the placenta, that it is a 
lateral formation, that the mass is developed in a sac, arising 
from the end of the column—the embryonary sac, the 
communicating tube is branched at an early period.

upper half of the sac.

that it is thus.

o. The membrane of the sac is here and there traced. 
At the time of inflorescence or very soon after, the co- 
lumnar tissue is very evident, appearing to be continuous 
similar to that of the placenta ; the situation of the sac is at 
this time occupied by opaque tissue. 
After the protrusion of the cotyledons, the nucleus and 
subalbumen do not undergo much if any change, the coty- 
ledons have commenced to be conduplicate, when twice 88 
long as placenta, the nucleus when then putes m in size 
is very hard, m subalbumen is enlarged, the radicle i$ 
still enclosed in
