deposit on the convexity of the anterior end of the centrum, 
although none on the concavity at the posterior end of 
centrum of dentata. Besides these, there were found five or 
six small detached pieces of bone, varying in size from a 
grain of oats to a moderate sized pea. These last must, I 
think, have been detached by wrenching from the superior 
spinous process of vertebras dentata. 
Remarks on Case .—This is one of the most unusual cases I 
have ever met with. I do not think there was any direct 
injury to the spinal cord itself. The symptoms throughout 
were tho'se produced by external pressure caused by the 
hemorrhage and inflammatory swelling resulting from the 
injury to the bones and soft structures at the seat of 
the fracture. I never before had occasion to keep an animal 
lying down for such a prolonged period, and if I had to do it 
again I would from the first utilize the platform arrangement 
with removable slats in addition to the air beds. I think by 
thus removing pressure from the points of the hips, an 
animal could be kept in the recumbent position for a very 
prolonged period without the development of very serious 
bed sores. 
So far as the fractures were concerned recovery seemed 
complete. The mare was not allowed to execute any very 
extensive movements of her head and neck, but the limited 
movements she was allowed to make were made with the 
greatest freedom on her part. 
(ESOPHAGEAL OBSTRUCTION. 
S. R. Howard Y.S., Hillsboro, Ohio. 
During the afternoon of the 19th of September last, I was 
called to T. McDonald’s farm, Willitsville. Early in the 
morning of the same day a large draft horse became choked 
while eating oats, Owner promptly attempted to unchoke 
him, using the butt end of a buggy whip. During the 
struggle that ensued, the horse bit off and swallowed a piece 
of the whip about one foot long.
