scious, holding his head to the right side, and turning round in the same 
direction. 
He remained in this condition for five days, and on the sixth he was 
found down, struggling violently, and steaming with perspiration. I 
advised the owner to have him destroyed. 
Post mortem .—I found the right hemisphere of the cerebrum enlarged, 
containing about two ounces of pus. In reply to a question, he said that 
the abscess was not in the substance of the brain, nor did it appear to be 
contained in a sac. 
Mr. Barnes then exhibited a specimen of ostitis, with a deposit of new 
bony matter, on the sixth and seventh cervical vertebrae, of which the 
following are the notes. 
The subject was a grey mare, five years old. I was called to examine 
her on the 8th of February. I found her lame in the off fore leg, accom¬ 
panied with atrophy of the antea and postea spinati muscles of the lame 
shoulder, which I concluded was the result of a sprain. 
Treatment. —Rest, hot fomentations, followed by gentle stimulation, 
which was continued for a fortnight with satisfactory results. The fol¬ 
lowing week she fell off her food, and showed signs of stiffness in the 
neck, accompanied with general wasting of the cervical muscles. On 
manipulating the inferior portion of the cervical vertebrae the animal 
evinced great pain. 
I ordered hot fomentations and stimulating embrocation to be 
applied daily, accompanied with the internal administration of vegetable 
tonics. 
This treatment I continued for a fortnight with no beneficial results, 
when I informed the owner that I anticipated an unfavorable result, and 
asked to be allowed to have a professional gentleman in consultation. 
Mr. Cartwright, of Wolverhampton, was called in on the 4th of March, 
and, after a careful examination together, we came to the conclusion 
that the atrophy of the muscles was the result of concussion to the cervical 
vertebras. 
On inquiry we ascertained that about a month previous to my first 
visit she had broken loose whilst out at exercise, and was supposed to 
have leaped or fallen over some iron hurdles. 
A fresh sheepskin was applied to the neck for twenty-four hours, after 
which a strong embrocation was rubbed over the whole of the neck, and 
vegetable and mineral tonics were given internally, but with no improve¬ 
ment. On the ‘26th of March she was found down, and unable to rise. 
The following day I recommended her to be killed. 
Post mortem .—On stripping the skin trom the neck I observed the 
muscles of the inferior cervical region to be of a peculiar greenish colour, 
and on cutting down to the bone a small quantity of a greenish-looking 
pus made its appearance, which convinced me that extensive disease of 
the bone was present. On examing the two vertebrae involved you 
find that the deposit of bony matter extends within the neural canal, as 
well as upon the outer surface of the bones. And he (Mr. Barnes) 
would like the opinion of the members on the following peculiarities of 
this case, viz.:—1. The length of time between the supposed cause of the 
injury and the first symptoms of lameness. 2. Why was there not im¬ 
mediate stiffness of the neck with excessive pain ? And 3. Why should 
the muscles of the shoulder be the first to become atrophied ? 
An interesting discussion followed, and the general opinion expressed was 
that the original cause of the diseased condition had been a shock inflicted 
on the bones of the neck, setting up inflammatory action, and as this 
inflammation, from the appearance of the deposit, seemed to have com-
