observed the same complete adhesion of the ovarium and calyx; the same ori 
ginal solidity ; the same subsequent sphacelation visible along the centre of the 
style, and terminating at the site of the future excavation: the same excavation ; 
the same subsequent appearance of the ovulum ; the same formation, inclusion, 
cotyledonary division and evascularity of the embryo; the same apparent short- 
ening and almost total disappearance of the funieulus; the same nudification of 
the apex of the radicle; the same degree of coloration, and the same softening 
down of the ovarium. "This in one species is carried to such an extent that 
only a portion of the base of the capsule remains in its original fibrous state; so 
that the greatest part of the albumen and immense radicle are enveloped by 
the viscous tissue*. 
Ovula of Viscum. 
In the earliest stage at which I have been able to examine the ovulum, I 
find a similar adhesion of the ovarium and calyx. The outline of the former 
is distinct, and the communication of its apex with the central canal leading 
from the base of the style open and very free f. There is no development of 
viscous tissue. Towards the apex of the ovarium there is a cavity communi- 
cating with the canal leading from the stigma containing a cellular, mammil- 
liform, central, but not papillose body, attached by a broad base, its apex 
touching almost the termination of the canal. This is connected inferiorly by 
à thickish opake line running through the centre of the ovarium to its base. 
This line is evascular, and consists merely of rather dense tissue. At this 
period the nipple-shaped process, as I may call it, is brownish +. 
No important change occurs until after impregnation; the only interme- 
diate ones being the diminution of the. diameter of the canal, and its greater 
length after impregnation, so far as may be judged of by the sphacelation of 
the stigma, the process is very apparent 
attenuated. From the base of the central line, which runs from the base of 
the process to the corresponding portion of the ovarium, two brown lines are 
apparent, curved upwards and outwards. These lines are of a much deeper 
brown than the rest of the process ; corresponding to one of the terminations 
of the curved lines there is a small lateral excavation, which is partly occupied 
by broken-up tissue, partly by a sac which is attached to, and hangs from that
