A. CHINNIAH. 
some time with palliative drugs as in cases of ordinary hsema- 
turia; but when the case assumed an obstinate nature, I sus¬ 
pected that there must be some mechanical agent, such as a cal¬ 
culus, doing the mischief as the symptoms suggested. The ani¬ 
mal was examined per rectum and the presence of the calculus 
was diagnosed with certainty. 
Symptoms .—There was painful straining during micturation, 
but at times the urine passed was of normal color and consist¬ 
ency. After brisk exercise the urine passed contained blood 
corpuscles and pigments in abundance, and the expression of the 
patient during the passing of urine indicated great pain. The 
appetite was all throughout good and there was no noticeable 
rise of temperature. As soon as the proper diagnosis was arrived 
at I informed the owner that the animal must stand an opera¬ 
tion which, if it succeeded, was the only means of saving the 
animal. 
Modus Operandi .—The instruments taken for the operation 
were scalpels, sharp-pointed bistoury, Symes’ artery forceps, 
bull-dog forceps, stone forceps, Gullion’s lithotritor, male cathe¬ 
ter and the female washing catheter. 
The animal was thrown on the nearside and a general anaes¬ 
thetic (chloroform) was administered. The penis was pulled 
out, washed and lubricated, and the catheter was passed and 
the penis retained all throughout in this position by an assis¬ 
tant told off for the work. The off hind leg was drawn a bit 
in front. I took my position just near the croup. The tail 
was washed antiseptically and given in charge of another assis¬ 
tant to be kept in the desired position. An incision was made 
two inches below the rectum along the middle line of the peri¬ 
neum downwards. When the urethra was reached, the sharp 
point of the bistoury was introduced into the tube (urethra), 
which was eventually slit open to admit the passage of the 
forceps. When the forceps were in the bladder the stone was 
grasped, with the assistance of my left arm, in the rectum. 
Several attempts were now made to remove the stone without 
performing cystotomy or lithotrity ; but they proved futile.
