REPORTS OF CASES.

at this time served by the stallion, and during gestation and 
until the foal was weaned (August, 1891), was quiet. After 
the foal was weaned, the attendant could scarcely harness 
her; she kicked viciously, and oestrum was constant. Six 
months before being served by the stallion, I prescribed 
potass, brom. in ounce doses until a pound was taken ; after an 
interval of two weeks, the same was repeated without im¬ 
provement. In October, owner number 3, who had bought 
her at public sale, could not work her. I ordered her to be 
served again by the stallion, which was done four times in one 
week, and so aggravated the symptoms that she could not be 
groomed. The owner brought her to me to have her spayed, 
and after explaining the risks to him, he decided to have the 
operation done. Not wishing to assume the whole responsi¬ 
bility and not having the proper instruments, I asked Dr. 
Harger to assist me, which he kindly did, performing the op¬ 
eration himself. 
The mare kicked so furiously when touched that it was im¬ 
possible to do the operation standing up or even in the stocks, 
and we had to cast her. We decided upon the vaginal opera¬ 
tion, using an improvised vaginal dilator and chain ecraseur. 
The displacement of the abdominal viscera because of the re¬ 
cumbent position made the operation laborious, and the ovaries 
had to be cut off within the peritoneal cavity. The hemor¬ 
rhage was insignificant; temperature never above ioi^° F.; 
appetite perfectly normal; discharged from the University 
Veterinary Hospital on the tenth day after the operation. 
She was perfectly quiet, could be thoroughly groomed, 
showed a disposition to lie down, and had a slight vaginal 
discharge during the following two weeks, when the old 
symptoms returned, though not to the same degree. 
At the present writing the animal is in perfect health and 
gives but little trouble in harnessing to the cart to which she 
has been working every day. She is improving daily, so as 
to lead us to believe that a cure will eventually be effected. 
The left ovary was enlarged and indurated, and the histologi¬ 
cal changes, which unfortunately have not yet been deter¬ 
mined, will be reported at a future date.
