EXTRACTS FROM EXCHANGES. 
disease. It was a horse which had three fistulse of the poll for 
five weeks. These had been freely opened, broken tissue had 
been removed, decayed structures taken off, and free injections 
and dressing's of chinosol resorted to. After a month of treat¬ 
ment, although the external wounds seemed ready to close, the 
bottom, was still diseased. No granulations were forming and 
the suppuration, quite abundant, was increasing in considerable 
quantities. It was then that the author cut very freely forward, 
between the ears, and finding the occipital bone bare and rough, 
he scraped it and dressed the part with icthyol. From that 
moment, with the exception of the formation of two little ab¬ 
scesses on the near side, the wound went rapidly on to healthy 
granulation. The horse was operated on, say, about the end 
of June, and was convalescent enough to be sent out to grass on 
the 16th of July. He was put to work later, having made a 
perfect recovery.—( Vet. Record .) 
Fracture of the Dentata. —In the Veterinary Record 
there is reported a case of fracture of the dentata, which had 
taken place in a four-year-old fill) 7 while being led out of her 
box. She was led into the yard by an ordinary hemp halter, 
and after going a few yards, without any warning, she reared up 
and fell right over on some granite stone pavement and died im¬ 
mediately. At the post-mortem a great deal of extravasated 
blood was found underneath the skin in and around the atloido- 
axoid articulation, and on further examination it was found that 
the dentata was broken into three pieces—fractured through 
the odontoid process and the body of the bone. The spinal 
cord was severed and much lacerated.— [A similar case occurred 
some years ago in one of our patients, but the animal was suffer¬ 
ing with osteoporosis. The specimen was placed in the museum 
of the American Veterinary College.—A. H.] 
Traumatic Peritonitis [By H . Swann and Billing - 
herst ].—A cart mare received a punctured wound between the 
15th and 16tli ribs, about afoot from the spine, on the near side. 
The wound was sufficient to admit a quill. Black oil had 
been used to dress the wound and pus had gathered into a 
pocket, owing to the destruction of the tissues by the sulphuric 
acid. The temperature of the animal was 104°, pulse 68, respi¬ 
ration hurried, mucous membranes injested, appetite poor. 
There was danger of deep cauterization and possibility of peri¬ 
tonitis. Still, by proper treatment, free incision, antiseptic 
dressings, etc., the wound assumed a better aspect and the 
animal seemed to go on towards recovery. The temperature
