#A. c. 539. The sao of a small inguinal hernia : the spermatic
chord behind ; the testicle at the bottom.
*A. c. 540. Crural hernia from the right groin of a male.
The relative position of the neck of the sac to the spermatic
cord and epigastric artery is well demonstrated. The sac is
as large as a hen-egg. A portion of the side of the bladder
is preserved.;
#A. c. 541. The sac of a crural hernia, containing hardened
omentum ; and to the margin of which a coil of the . sigmoid
flexure is adherent.
#A. c. 542. A small, obscure, crural hernia, the sac of
which is covered over with lymphatic glands.
#A. e. 543. A large mass of omentum which lay unreduced
for many years in a scrotal hernia. It is thickened and matted
into a confused heap, and exhibits marks of strangulation from
the neck of the sac.
*A. c. 544. Hernia diaphragmatis of the left side in a
full-timed, male foetus. The stomach, and nearly all the
small intestines are situated in the left cavity of the chest.
The lung of that side does not appear : the pericardium and
right lung are much pushed aside and compressed : the liver is
perfect : the outward form of the foetus is plump and good.
#A. c. 545. Internal strangulation by the urachus. The
subject of this singular preparation was a lady, about twenty-
two years of age, remarkably healthy, and of large and good
figure. She had been married several months, and had suffered
much from painful menstruation, but had not conceived.
She was seized suddenly with pain in the abdomen : symptoms
of most acute peritonitis rapidly followed, and death
was the consequence in a very brief space of time. During
the progress of the illness, various speculations were entertained
regarding it ; but the autopsy, alone, developed its
cause and nature. The abdomen was found distended with
serous and lymphatic effusions : the intestines and omentum
in the upper part of the cavity were agglutinated; but, between
the umbilicus and bladder there lay a large coil of
small intestine, perfectly black from strangulation, and free
from any such coating of lymph as that which existed elsewhere
on the peritoneum. The cause of this strangulation is
shewn in the preparation, and in a drawing which accompanies
it, to have been a distinct, firm, fibrous band, passing
from the apex of the bladder upwards and backwards, towards
the mesentery, around part of which it had formed a
tight noose. The vesical attachment of the band corresponded
accurately to that of the urachus, and of which it was
supposed by Professor Harrison, who made the examination,
to be rudimental. He considers this fatal band to be urachus,
for two reasons : first,: from its origin and structure being
identical with the remains of that tube ; and, secondly, from
the total absence of every other substance to which such name
could be assigned. Neither would it appear that the band
■ was adventitious or the result. of previous inflammation, as
the history of the patient affords no evidence to that effect.—
Professor Harrison.
A. c. 5451. A drawing of the foregoing preparation, taken
at the time of the autopsy, and which conveys clearly the
origin and appearance of the band, together with the mode
of its operation in producing strangulation of the intestine.
*A. c. 546. Intussusception of the small intestine in a child.
Several inches of one part of the intestine have been pushed
into and strangulated by the portion next below.
*A. c. 547. Cast of an enormous scrotal hernia of the right
side in an old man. The tumor extends one-third down the
thighs. Nothing but a wrinkled circle marks the orifice of
the urethra and prepuce : the penis has wholly disappeared in
the tumor.
*A. c. 548. Cast of a double scrotal hernia in a middle-
aged man. The hernias are of nearly equal size. Nothing
