hind leg: the driver stopped and examined the foot, but failed to 
detect anything amiss at that point, and upon continuing the jour¬ 
ney in a little while the horse began to manifest irregularity 
on the near fore extremity. Both of these conditions rapidly 
became so aggravated (falling down several times) that he was 
taken out of harness and placed in the stable, getting up and ly¬ 
ing down repeatedly during the night. 
When I visited him the symptoms looked very much like those 
of azoturia and when with them the subject was carefully consid¬ 
ered, I was much tempted to make my diagnosis in that direction. 
It being difficult to make a minute examination, as the patient 
was in dark stall of a cellar stable, and having no catheter to 
examine his urine, the animal was placed as comfortable as possi¬ 
ble in his stall and seen the next morning in company with Dr. 
Coates. On that day he was found lying down. .Rising with com¬ 
paratively little assistance, his lameness was very evident and pecu¬ 
liarly characteristic. Unwilling to move, when made to do so he 
moved forward with very short steps, hesitating; the toe forward, 
almost the walk of a laministic patient. The feet were cool, the 
fetlock of the near fore and off hind leg were swollen, somewhat 
warm and very painful on lateral pressure, and while there was 
no tendency of the fetlock to descend nor to the elevation of 
the toes, a diagnosis of giving away of the sesamoid ligament 
was made and the animal ordered to be destroyed. 
Post mortem lesions were very interesting; upon removing 
the skin the cellular tissue from the foot up to the knee was 
found infiltrated with blood of a dark color; the structures other¬ 
wise were all healthy, with the exception of the sesamoid bones 
and the ligaments attached to them; the suspensory ligament of 
the off hind leg was torn almost completely from its point of at¬ 
tachment to the bone and carrying with it fragments of the bone 
itself, the severed ends giving a crepitant sensation and being 
deeply stained with eccliymotic spots. In the near fore leg this 
condition was directly reversed, the inferior sesamoid ligaments 
being torn from their insertion to the sesamoids.
