become smaller as the albuminous mass increased in size ; 
smaller certainly just as the cotyledons are going to pro- 
trude; the nucleus undergoes no change. 
l. The anomalies are, curvature of the embryo sac. 
2. Protrusion of the albuminous mass beyond the ovulum, 
while the sac originally was internal. 
3. The protrusion of the cotyledons, nakedness of em- 
bryo, but above all the direction of the  radicle, the 
funiculus of which points to, and not from the apex of the 
nucleus, which also appears to be its direction at a every 
early period. 
This also is well worthy of notice, as confirming the perma- 
nence of the direction of the radicle—that in the mature 
seed, its general direction is such as it would have been, 
had the cotyledons passed up inside the ovulum. 
The anomaly of direction in the embryo, if the line of 
first appearance, which is axile, is considered is not so 
great as it would, at first sight appear. Although there is 
no appreciable mechanical cause, why the cotyledons assume 
so strange a direction. 
Soon after evident impregnation, the fertilised ovule is 
twice as big as the others, is split open at its apex from 
which protrudes a fleshy soft roundish mass, and inside its 
pressure shews the presence of a roundish body. 
The centre of the protruded mass is more membrano- 
cellulous, and to it, portions of tubes may be seen adhering. 
During inflorescence, and even when the stigma is black- 
ened the ovula (some times 3) are club-shaped with an umbili- 
cate or lobed apex, from the centre of the umbilical cavity 
of one at least, an obscure small protrusion was observed ; the 
ovula appear solid: pressure however causes the escape the 
grumous fluid; at this period a single tube may often be 
seen running down to the apex of the ovulum. 
From the navel or sinus of the lobe, there appears to ne 
obscure channel leading to a less obscure cavity; towards
