urine was still the same. I then altered the injection for a de¬ 
coction of oak bark, but it was of no use. I was extremely puz¬ 
zled to account for the symptoms. I had refrained from passing 
the catheter, fearing the uterus might be again ejected in her 
laborious throes: but on now endeavouring to do so, I could find 
no passage. Inversion of the bladder, until then, had never en¬ 
tered my imagination, and I could not even then believe it: the 
inversion of the uterus, as I had considered it, was hard and 
turgid, and seemingly one dense substance. 
May 2.—The mare got worse towards the evening, incessantly 
straining and groaning. 
3<f.—In her laborious throes she had again ejected the inversion, 
and it now hung several inches below the vagina : I recommended 
that she should be destroyed, and she was sent to my yard for 
the purpose; I kept her, however, during the day, endeavouring 
to replace the parts, and by bleeding and sedatives to lower the 
inflammatory symptoms. She became gradually weaker during 
the day; the throes more laborious and distressing; the pulse 
rose to 90 before night. One symptom which attended her was 
a constant endeavour to get as high as she could with her fore 
feet. At times during the night she was totally insensible 
through excess of pain. 
Very early on the 4th she was shot. 
Post-mortem examination .—There was the highest degree of 
inflammation of the rectum; the bladder was completely in¬ 
verted, the fundus projecting from the vagina, and the meatus 
w as distended as thick as my wrist. The parietes of the bladder 
were fully one inch and a half thick, and it would have been 
impossible to have determined that there was fluid inside until it was 
opened. In the cellular membrane, between the anus and uterus, 
there was a collection of urine, about a pint and a half; but 
from the intense state of inflammation of the anus and surround¬ 
ing parts, it was totally out of my power to trace the ureters; 
one or both must have been ruptured. The animal lost her 
milk on the third day, and the foal was fed upon cows milk. 
• For the first fortnight he consumed fifteen quarts per day, and 
afterwards much more : it thrives surprisingly.
