114 PROF. M. WATSON ON THE ANATOMY OF THE 
upper surface of the bladder as far back as the points of entrance of the ureters, whence 
it is reflected to the under surface of the corpus uteri. ‘The lateral surfaces of the 
bladder are also in part invested by peritoneum, whence this membrance passes to the 
lateral and superior abdominal walls. The whole of the lower surface and base of the 
bladder are therefore destitute of peritoneum. As in the male! so in the female, the 
apparent thickness of the vesical walls is due rather to the peritoneum and subperitoneal 
connective tissue than to that of the muscular coat. 
GENITAL ORGANS. 
Ovaries.—Kach ovary is oval in form, and measures 14 inch in length, and 1} inch 
in greatest breadth, and about 2 inch in thickness. Lach is distinctly lobulated on the 
surface, that of the right side more so than that of the left. The grooves or fissures 
which separate the lobules are, however, quite superficial, and do not extend to any 
great depth into the stroma of the ovary except in the case of that of the right side, in 
which, close to the superior or attached margin, are two deep fissures, one of which 
almost completely severs about } inch in breadth of the ovarial substance from the 
rest of the organ, the detached portion being further subdivided into two parts by a 
second short but deep fissure. There is no trace of either of these deep fissures in the 
ovary of the left side; and probably we are therefore justified in regarding their pre- 
sence as an individual peculiarity. Hach ovary is suspended over the mouth of a very 
complete peritoneal pouch by means of two ligaments, one of which is attached to each 
end of the organ. The internal ligament measures 14 inch in length, and passes from 
the inner end of the ovary to the extremity of the uterine horn of the same side, whilst 
the external ovarial ligament extends outward and forward from the outer end of the 
ovary, and can be traced for a distance of 7 inches in the peritoneum, in the substance of 
which membrane it at length disappears. This ligament, in all probability, corresponds to 
the external ovarial ligament of Hyena crocuta; but whether, as in that animal, it was 
attached to the diaphragm could not be determined, as the viscera had been removed from 
the cavity of the abdomen. Both ovarial ligaments are in the form of stout fibrous 
cords. ‘Che pouch, at the mouth of which the ovary is placed, is formed of peritoneum 
continuous with that forming the broad ligament of the uterus. Its opening, in the 
natural position of the parts, is directed upwards and forwards (toward the spine of the 
animal); so that the bag hangs vertically below the ovary. The bag itself is of large 
size, measuring 3 inches from side to side, 3 inches from above downward, and 14 inch 
from before backward, and closely resembles the corresponding structure of Hyena 
crocuta. Its posterior free margin is formed by the ovary and ovarial ligaments, its 
anterior by the free edge of the wall of the sac. As pointed out by Mayer?, Miall and 
Greenwood ®, the ovarial pouch is separated into two compartments by means of a
