OBSTACLE TO PARTURITION BY OCCLUSION OF THE OS UTERI. 
A cow was in labor for forty hours. "When seen, she was 
standing up, the hind legs apart, the hocks flexed, the vertebral 
columns bend upwards; the animal was making continued efforts. 
A large, red tumor, bosselated, situated in the place of the vulva, 
was hanging down to the hocks; through its walls the head and 
legs of the foetus were easily made out. The covering of this 
mass was the mucous membrane of the vagina, continued with 
the skin of the perineum and of the gluteal region. The open¬ 
ing of the vulva entirely disappeared and the neck of the uterus, 
situated at the lower part of the hernial sac, was but a small 
depression, scarcely half a centimeter deep. The walls of the 
neck, closely together, are so adherent that it is impossible to 
introduce either the finger or a small instrument to operate the 
dilatation. Everything has returned to its normal position, and 
the entire occlusion of the neck becomes more manifest. 
With an ordinary bistoury a way was made for a blunt instru¬ 
ment, with which three incisions were made, two superior—one to 
the left and the other to the right—and the third to the lower 
part. As these were made, the opening dilated and the head of 
the calf was soon engaged in the pelvic strait and ready to 
come out. The success was perfect—calf and cow got well.—

SALIVARY CALCULUS IN A FEMALE ASS. 
A female ass, bought in 1875, had at that time a small tu¬ 
mor on the inferior part of the left cheek. This tumor kept 
on growing up to October, 1879, when it interfered with mastica¬ 
tion ; the animal refusing all food. She was in good condition, 
fat, and nursed a little foal four months old. 
At the lower part of the left cheek she presented a somewhat 
round tumor, well prominent, about seven centimeters back of 
the commissure of the lips, and ten centimeters from the eye. 
Its contour, regularly circular forward and downward, was 
straight behind and followed parallely the posterior border of the 
inferior maxillary. Above it was limited by the anterior border
