AZOTURIA, WITH STRAIN AND ATROPHY OF THE 
GREAT DORSAL MUSCLES IN A MARE. 
By W. L. Williams, V. S., Prof. Surgery and Obstetrics, New York State 
Veterinary College. 
It is not unusual to meet with eontusions, strains and frac¬ 
tures as a result of casting horses for operations, and at times 
we have had occasion to observe tympanitic colic after tedious, 
cramped confinement, but we have neither observed nor fouud 
recorded, among these accidents, the disease we know as azoturia 
or hsemoglobinuria. 
The subject was a common-bred mare, aged eight years, used 
for light farm work and well kept by a very gentle owner. She 
was worked regularly during the summer, but quite irregularly 
during the winter. 
For three years she had suffered from mild double navicular 
disease, which became more continuous and pronounced about 
September, 1896, on which account she was presented at the 
college clinic on Feb. 16, this year, for operation. 
On the 15th, the patient was led about nine miles and on 
the 16th completed her journey to the college, a further distance 
of six miles, and was placed in the college hospital at 2 P. M. 
She was in robust health and high condition, without excessive 
fatness, and, having travelled the entire distance at a walk to the 
halter, she arrived wholly without fatigue. On the evening of 
the i6th, and morning of the 17th, she was fed sparingly on 
wheat bran and hay, after which she was led a short distance 
to a smith for shoeing, was allowed no food at noon, and was 
cast for neurotomy at 2 p. m. of the same day. She was cast 
with ordinary sidelines and surcingle, all four feet being securely 
fastened to the surcingle rings, well up on the sides of the chest, 
the fore feet being alternately released for operating.
