REPORTS OF CASES. 
I got a number nine and number twelve human gum catheter ; 
passed first the small, and then the large one through the strict¬ 
ure thus dilated until I could get a metal mare catheter through. 
It then passed four or five inches further, when it again came to 
a standstill. I could then plainly feel and hear the metal catheter 
strike a stone, but with some manipulation it apparently passed 
by. Then I took a regular gum male catheter, but could not get 
it past the stone until I used a wire stillet and bent the point 
slightly, turning the point downward and slightly to the left; 
then with some trouble I passed it to the ischial arch, when it 
refused to go further, but after withdrawing the catheter there 
was some little flow of uritie, and by pressure on the bladder I 
got considerable urine away. Then I left, to call the next day. 
Feb. 11.—Found the horse weaker; no appetite; pulse very 
fast. Temperature, 104J° F. Some urine still dropping ; sheath 
and perinseum greatly swollen. I passed the catheter, and got 
through *the first stricture, and after some manipulation I passsd 
the stone and got as far as the ischial arch, but could go no 
further. 
I now decided to operate, and cut down to the catheter at 
the arch (the same as for lithectasy); but on reaching the cathe¬ 
ter imagine my surprise when I found that it (the catheter) was 
not in the urethra; but in passing the stone I had ruptured the 
urethra, and passed up outside of it. 
I ordered the horse killed, and made a post-mortem. Fol¬ 
lowing up the urethra, I found the mucous membrane healthy to 
the first stricture; from there on it was somewhat dark and con¬ 
gested. I found the stone larger than a hickory nut, and about 
that shape, with many rough projecting points, what, I be¬ 
lieve, is called a mulberry calcus. The membranes and all tissue 
around it were completely broken down, but no external swelling 
•nor anything else to show the condition from the outside of tlie 
penis. The catheter had broken through here and passed up * 
alongside of the urethra in the areolar tissue, which was thor¬ 
oughly infiltrated with urine. This had been the cause of the 
intense swelling. There were four strictures in the urethra above 
the stone mentioned, and in each stricture a small stone, varying
