EXTRACTS FROM EXCHANGES.

prostration. By abdominal palpation, a mass is felt, slightly 
depressible, about lo centimetres (5 inches) long, upon which 
pressure is painful. Surgical interference is decided upon, and 
laparotomy performed. With difficulty, after incision of the 
intestines, the greatest part of a piece of cord, knotted in several 
places, is extracted by careful tractions. But for fear of too 
much laceration a very small piece is left in the intestines. 
The wounds were treated antiseptically. The dog did well for 
two days, but ultimately died. Two ulcerations were found in 
the intestines back of the part which had been incised for the 
operation, and which were due to the peristaltic contractions of 
the organ, which, by rubbing against the remaining piece of 
cord, had been cut through. The wound of the intestines at the 
seat of operation was firmly closed. The piece of cord extracted 
when unrolled measured 6 metres (about 6 yards) in length._

Hypertrophy of the Prostate and Perineae Hernia 
OF THE Bladder in a Dog. —A twelve-year-old fox terrier, 
writes Mr. Caronyiau, was brought to me in great pain ; its 
back was arched, its abdomen contracted, and it made useless 
efforts to micturate. Between both ischii there was a round 
swelling extending from the perineum to the base of the 
tail. This swelling was as big as the fist; it pushed the anus 
upwards and to the left; it was somewhat soft, not very painful, 
and fluctuated. Rectal exploration revealed a firm, hard mass, 
situated at the anterior part of the pelvis and behind it a tense 
pouch, full of liquid. The mass was the hypertrophied prostate, 
the pouch was the bladder. A catheter introduced in the 
urethra could not enter the bladder. Puncture of the external 
tumor gave escape to normal urine. This gave temporary re¬ 
lief. The dog was destroyed the next day. At the post-mortem 
the prostate was found largely hypertrophied and the body of 
the bladder was turned backwards, and its neck acting as a 
hinge, the anterior extremity of the organ had become posterior 
and was in contact with the skin of the perineum.— (^Joiirn. of

Abnormal Retention of the Fge:tus in a Cow [By Mr. 
P , Leblanc \.—The owner of the cow is sure that his animal is 
in calf, but lately he cannot find it by manipulation. He fears 
that he has made an error, as the cow continues to give a quan¬ 
tity of milk superior to what she ought to, if parturition was 
close at hand. The author by physical signs cannot detect the 
presence of the calf, but by rectal examination finds on the left
