REPORTS OF CASES. 
When walked about 100 yards, there appeared a difficulty in the 
animal’s breathing; she immediately became greatly distressed, 
and came very near falling ; he then directed the boy to lead the 
mare to this place, which was done. 
I had the animal trotted up and down the block four times, 
without producing any of the above-mentioned symptoms; but 
upon having her ridden, the urgent dyspnoea presented itself, 
along with a flow of blood from both nostrils and mouth. 1 had 
the animal returned, and then found the very rare condition—a 
fracture of the trachea; midway in its length the edges of the 
fractured tube were partly everted and partly inverted, and far 
apart; in extent it was about four inches. Pressure upon the 
skin over the opening produced symptoms similar to those shown 
when the animal was ridden. I believe this to be a very rare 
occurrence, and can find no account of the same in the veterinary 
works I possess. 
In the treatment I could do little, on account of its low situa¬ 
tion. If it had been higher up I might have inserted a tube with 
probable good results, but as it was, I advised the owner, should 
he retain the mare, to drive her with the head in as nearly the 
natural position as possible, using the martingale to accom¬ 
plish it. 
I have since heard nothing as to what benefit was derived 
from the above suggestion, nor do I place much stress upon it. 
My sole object in sending you this was to find if there had been 
any similar case recorded, trusting it will be of interest to the 
younger members of the profession. 
PECULIAR CONDITIONS FOUND IN THE UTERUS OF A MARE

By A. C. Young, D.Y.S. 
I have long intended writing you, but a doubt of its accept¬ 
ability, and having little or nothing of interest to write about, 
it has been postponed until the discovery of the following remark¬ 
able case. 
I give the history in its entirety, and ask your opinion, as a
