OPERATION FOR IMPERVIOUS URACHUS. 
201 
Though the lithotritor was at hand ready for use I preferred 
to perform cystotomy. The bistoury was passed along the 
urethra into the mouth of the bladder, and guided by my left 
hand per rectum to prevent a rectal fistula, an incision was made 
dividing the mouth of the bladder, prostate glands and 
(unavoidably) the pudic artery. The latter was promptly 
caught and ligatured. This made the operation simple, and 
with the help of the hand, per rectum, the removal of the cal¬ 
culus was easy enough. 
The calculus weighs 3^ ounces and its circumference y]f 
inches. It is not spherical, but convex on both surfaces, and 
the margin unbroken and round. The outer layer is apparently 
composed of phosphate of lime and the inner of oxalate of 
lime. 
After Treatment .—The bladder was washed with a tepid 
solution of boracic acid. The wound was antiseptically 
treated and painted with iodoform and eucalyptus oil and left 
open. The animal micturated soon after the operation, and 
passed urine both through the wound and along the natural 
passage. The passage through the wound ceased after the first 
day of the operation—January 27, 1901. The wound is being 
daily dressed antiseptically with what I call an antiseptic emul¬ 
sion composed of boracic acid, carbolic acid, iodoform, eucalyptus 
oil and glycerine, and satisfactory progress continues to be 
made. The wound is 2 inches in length and a quarter inch 
deep now.

Until the later treatment for parturient apoplexy the country 
practitioner usually had a chill when the symptoms of this 
trouble were described along with a request for help, and some¬

in and says that his young colt is unable to stand, passes urine
