reddened. As time passed on the symptoms of irritation and 
pain increased whenever the mare was driven. If driven a short 
distance, the act of mieturation was immediately performed on 
being stopped. 
At such times the irritation manifested was slight and the urine 
only slightly reddened; but if driven three or four miles the irri-. 
tation was more severe and the urine was blood-red. 
Through the winter the symptoms increased and much curi¬ 
osity was excited by the mare that passed blood. Wherever she 
was stopped she left a trail of blood in the snow. 
She was finally in such a condition that it was impossible to

She is in excellent condition otherwise; never looked better in

When the mare was backed out of the stall I found her fat and 
manifesting every sign of good health. 
She was trotted a short distance and then tied on the floor and 
left quietly. In a few minutes, after one or two ineffectual at¬ 
tempts, manifested by stepping with the hind feet, expulsive 
efforts and whisking of the tail, she passed about six ounces of 
urine slightly tinged with blood. 
I then gave her, hypodermically, gr. iv. morphia; secured both 
hind feet with hobbles and a line passed between the fore legs 
and over the neck. 
Giving the line to an assistant, who also held the twitch applied 
upon her nose, I first passed a soft metal catheter, keeping the 
end closed, as I did not wish to draw the urine if there should be
