THE ALIMENTARY TRACT 217 
with the aponeurosis at the ring but the gut was not 
adherent at this point while it was attached within the 
sac outside the muscle, thus formmg the incarceration. 
Apparently the sac had dissected between the muscular 
layers for it could be followed for several centimetres in 
some directions. A Hog Deer {Cervus porcinus) had 
apparently suffered an injury in the flank for at one point 
the muscles were irregularly cicatrized and a rent was 
present through which several loops of intestine and a 
band of omentum had escaped, being adherent to fascia. 
No injury to the skin was apparent. 
Another Indian Antelope showed a clean traumatic 
rupture of the muscle and peritoneum in the right 
inguinal region tvithout penetration of skin. An acute 
hernia had occurred which was lightly adherent to fascia 
and an acute peritonitis was beginning. The bowel was 
hoAvever not strangulated. 
An aoudad {Ovis tragelaphus) seems to have suffered 
an injury by a pointed object (horn?) just to the right of 
the ensiform cartilage for at this position there is a 
circular hole, with smooth healed edges, in the aponeuro- 
sis, permitting the emersion of a peritoneal sac contain- 
ing omentum. All parts were adherent but no acute 
inflammation existed. 
What may have been a hernia or a relaxation of the 
transversus perinei was observed in an. Undulated Grass 
Parrakeet {Melopsittacus undulatus). A bulge about the 
size of the finger end was seen externally, beside and 
behind the anus. This proved to contain several loops of 
bowel and a mass of fat. 
A lateral abdominal hernia was seen in a Barbary 
Turtle Dove (Tnrtur risorius). It consisted of a per- 
itoneal sac and two loops of intestine. This protrusion, 
while firmly fixed in its unnatural position, was in no 
way constricted.
