pletely to one side, and from the enlargement downwards of the cel- 
lular body, their bases do not correspond, as in fig. 13. A cavity 
is apparent at the apex of the cellular body.

Embryo in a very young state from the same; it is somewhat dilated, 
and more dense at its inferior free extremity.

Barren (or rather abortive) ovulum from the placenta of the same; 
very few globules or molecules are visible, and they are either sta- 
tionary or sluggish. 
With this exception it agrees with the abortive ovula examined in 
earlier stages.

that of fig. 15. The embryo is seen in situ. 
The same embryo detached. The apex of the cellular body remains, 
and to this the embryo is seen to be attached. There is an evident 
commencement of the cotyledonary division visible at its lower ex- 
tremity.
