REPORTS OF CASES.

limbs were cramped (or “asleep”) and after getting headway, 
always under force, would walk fairly well. Her countenance 
showed no signs of pain nor distress except for a moment, when 
the “shooting pains” occurred. The bowels were normal and 
the appetite excessive rather than lessened. 
After carefully weighing all facts and excluding apparent 
ailments, particularly rheumatism, for want of completing 
symptoms, I made a diagnosis of thrombosis of some large 
internal vessel, even mentioning the pulmonary artery as the 
probable seat, on account of the increased respirations. I felt 
reasonably sure that it was not in the femoral or axillary arter¬ 
ies (which are the most common seats) onaccount of all four 
limbs showing trouble, with possibly more marked manifesta¬ 
tion of the ailment anteriorly, but there was no coldness, and 
the symptoms did not abate after rest. The quickened and 
increased respirations suggested the pulmonary artery, or at 
least the anterior aorta, though this would occur (but to a less 
extent) in thrombosis of the posterior aorta. 
Prognosis was unfavorable. I put the animal under treat¬ 
ment, consisting mainly of iodide of potash and carbonate of 
ammonia, alternated. The temperature varied from 103° to 
105° during the progress of the ailment. No organic or in¬ 
flammatory disease was manifested until the last four or five days 
of the animal’s existence. Then gangrene of the lungs made 
its appearance without any preliminary symptoms of pneumonia. 
The animal never coughed, even after the 26th or 27th day, 
when I detected a most foetid odor of her breath. I then de¬ 
pressed her head, which would cause a profuse flow of a very 
foetid sero-purulent, slightly bloody fluid from her nostrils. 
I then informed the attendant that gangrene of the lungs had 
set in, and that her end was not far off. Emaciation progressed 
from the start, though she ate full rations, even finishing a full 
feed of oats the evening preceding her death, which occurred 
during the night of October 20th, 1901, 23 days after the 
commencement of her ailment. 
I should add that on about the tenth day she showed an im¬ 
provement to such an extent that it seemed that her recovery 
was assured, but after a couple of days of this apparent improve¬ 
ment, she relapsed into her former condition without material 
change until the pulmonary gangrene set in. 
Post-mortem .—I have never before seen so many patholog¬ 
ical conditions in one animal. It was simply remarkable that 
the mare lived so long. In the abdominal cavity there was
