blood, escapes from the nostrils. There is some roaring. The 
bony walls of the sinuses are normal and not painful to percus¬ 
sion ; no swelling of the glands. The general condition remains 
good, appetite and rumination normal. The author considers 
that the diagnosis in the first case might have been made by ex¬ 
clusion. In the second there was no doubt about it. At the 
post-mortem of the animal the maxillary sinuses were found the 
seat of disease, the right being more affected than the left.—

Congenital Diaphragmatic Hernia in Swine [By Mr. 
T. Biot ].—Out of a litter of nine pigs, four had died sud¬ 
denly in the space of two days, presenting symptoms entirely 
identical. They died in full condition of health after a copious 
meal. The other five exhibited all the external signs of perfect 
health. At the post-mortem of the last that had died, the 
abdominal cavity was found separated from the diaphragm, but 
this muscle was perforated in the left side of the superior por¬ 
tion with an elliptical opening allowing only the introduction 
of the index finger. In the abdomen there was only two-thirds 
of the small intestines, the balance of the intestinal canal, the 
kidneys and the genito-urinary organs. In the thorax, there 
was but one lung, the right was resting on the internal face of 
the ribs and adherent to it; it consisted in a sheet of spongy 
congested tissue about one and a half centimetres thick and 
resembling the lungs of fowls. The four-fifths of the thoracic 
cavity were occupied by a normal heart, the stomach filled with 
food, the pancreas, liver and duodenum engaged in the 
diaphragmatic opening. It is probable, not to say certain, that 
a similar condition existed in the three other dead pigs.— (Rec.

Hernia of the Bladder through the Urethra in a 
Cow [By M. Villemin ].—While attending a cow in labor, the 
author observed in the vagina a reddish bosselated tumor as big 
as the fist, moist and attached to the vagina by a short peduncle 
about the size of the little finger. On each side of this tumor 
there were two openings from which drop by drop escaped a 
fluid smelling like urine ; there was no urinary meatus. It was 
evidently the bladder which had everted throngh the expulsive 
efforts of the cow. The uterine torsion, which prevented the 
cow from delivering, having been reduced, the calf was ex¬ 
tracted. Reduction of the vesical hernia was accomplished 
only the next day, but with great difficulty. The animal suf¬ 
fered afterwards from purulent cystitis, but ultimately recovered.
