PLACENTATION OF THE SEALS. er 
to form the strong broad ligaments, and to be reflected upon the back of the 
bladder. The horns sprang from the bifurcation of the body. The right con- 
tained a large foetus, and measured 2 feet 6 inches along its anterior convex 
surface from the angle of bifurcation to the tip of the cornu; whilst the left, 
similarly measured, was only 9 inches; the circumference of the gravid horn at 
its middle was 20 inches, that of the non-gravid only 4 inches (fig. 1). 
A well-marked “ligamentum rotundum” arose from each horn about one 
and three-quarter inch from the tip, and extended between the layers of the 
broad ligament. A strong muscular diaphragmatic band passed from the tip 
of each horn. A short Fallopian tube also curved outwards and opened by a 
very wide fimbriated mouth on the inner face of a deep “ pavilion,” in which 
the ovary was lodged. The right ovary, about the size of the human testicle, 
contained a large corpus luteum. The left ovary was scarcely half the size of 
the right. Tortuous veins and arteries were distributed in the broad ligaments 
in immediate proximity to the ovaries. Numerous muscular fasciculi extended 
almost transversely outwards from the body of the uterus into the broad liga- 
ment on each side between its two layers. Tortuous veins and elongated ser- 
pentine arteries ascended beneath the peritoneal investment of the body of the 
uterus, and within the right broad ligament, to the gravid right horn. An 
injecting-pipe was introduced into one of these arteries, and another into a vein, 
and a transparent injection of carmine suspended in gelatine was passed into 
these vessels. The cavities of the left horn, of the left side of the body, and of 
the vagina were then opened by a longitudinal incision. The fore part of the 
left horn was occupied by a very viscid brown mucus, and was nine inches in 
length. It was prolonged for nine inches and a half into the left side of the 
body of the uterus, and the calibre at this part was twice as great as that of 
the free part of the horn. This portion of the horn contained no appreciable 
quantity of mucus, and there was no prolongation of the foetal membranes into 
it from the gravid side. The cavity of the left horn entering into the corpus 
uteri was separated from the corresponding portion of the right horn by a broad 
septum, which terminated in a free sickle-shaped border immediately in front 
of the os uteri internum. The cervix uteri was 24 inches in length, and pro- 
jected into the vagina, where it formed two very prominent lips which sur- 
rounded the os externum. Its mucous lining was thrown into longitudinal 
folds. The vagina was 6 inches in length, and its mucous lining possessed 
several strongly marked transverse folds. Both the vagina and cervix uteri 
contained a glairy whitish-brown mucus. 
An incision was then made into the gravid right horn where it entered into 
the formation of the corpus uteri, which was found to be widely dilated, and this 
incision was prolonged for a short distance into the free part of the horn. A 
similar incision was also made for a few inches through the uterine wall at the
