EXTRACTS FROM EXCHANGES.

ing; but the fourth day, observing at the base of the tail the 
appearance of a tumor of the size of a man’s head, which proved 
to be made by the extremities of the legs of the foetus, interfer¬ 
ence became imperative. Vaginal examination revealed 
through the walls the presence of the foetal extremities. By 
rectal exploring, the croup, head and parts of the extremities 
were made out and the movements of the well-alive foetus readily 
detected. In the presence of this extra-uterine gestation, it was 
decided to kill the. cow to save the foetus. On opening the 
abdominal cavity and tearing the envelopes a live calf was 
moved, weighing 38 kilos, which was successfully raised. The 
foetal envelopes were inclosed in a menbranous sac, very thin, 
pyriform, partly engaged in the pelvis and adherent to it. The 
uterus was normal in size and free from any injury.— [Annales

• Tearing oe the Sesamoid Tigaments and of those of 
InTERPHAEANGEAE Joints {By MM. Degive and Hen- 
drioux\. —If ruptures and lacerations of the tendinous and liga¬ 
mentous apparatus of the fetlock are well known, their tearing 
off from their point of insertion are not as common. The fol¬ 
lowing four clinical cases will serve to show their history, i. 
Rupture and Disinsertion of the hiferior Sesamoid Ligamentous 
Apparatus of Both Hind Legs. —Light draught horse, eight 
years old, laid up with a slight lameness on one hind leg. Re¬ 
turned to work, he became affected with hsemoglobinuria. 
When bi ought to the authors for treatment it was observed that 
the standing position was very painful ; the resting of the hind 
legs took place on the posterior face of the fetlock ; there was a 
fissure above the coronet and a separation of the cutidura with 
bloody oozing ; the legs from the hocks down were swollen, hot 
and painful. At the post-mortem, a complete giving away of 
the inferior sesamoid ligaments at their upper insertion was 
found. 2. Disinsertic7i of the Pe^foralis and Perforatus 
Tendons. —An eight-year-old pony, lame on the near fore leg was 
treated with a blistering application. After three weeks of 
treatment he was exercised, and had an attack of acute laminitis, 
which disappeared by proper treatment. He was sent to the 
country for his convalescence; he reached the place in a very 
bad condition ; he could scarcely walk, his standing was very 
painful, the resting of his hind feet took place on the heels, the 
toes were turned upwards ; there was a marked fissure above the 
cutidura. The tendon of the perforatus and the suspensory liga¬ 
ment had their normal firmness, but the perforans tendon was re-
