DISEASES OF THE URINARY ORGANS.

ulants were ordered to be given at intervals ; gentle pressure 

 was applied to the bladder by compressing on either side the 

 walls of the abdominal cavity, but without producing the 

 effect of emptying the viscus. An injection was also given, 

 consisting of oil with soap and water; and the pain still 

 continuing, hot flannels were applied to the abdomen fre- 

 quently. 



" The dog being a favorite, and the owner anxious, the 

 treatment was pursued to meet his wishes, although it was 

 considered that there was no hope of the animal's recovery. 

 He died on Saturday morning, February 13th. 



" Post-mortem Examination. — The abdomen was opened 

 down to the pubis, and part of the pelvis was removed. The 

 bladder and other parts of the urinary organs were dissected 

 out entire. 



" The bladder was observed to be dark in color over the 

 whole surface, from intense congestion. Upon making a sec- 

 tion into the viscus, there escaped a quantity of deep, dark- 

 colored fluid, and also two calculi about the size of large peas, 

 spherical in shape, and upon further examination, intermingled 

 with some mucus, there were seen numerous small ones of a 

 seed-like character ; one of a larger size was found to have 

 passed into the urethral canal, and there being perfectly im- 

 pacted, had resisted all efforts of the animal or contraction of 

 the bladder to overcome the obstruction. This appeared to 

 be the immediate cause of death. 



" The extensively-distended condition of the bladder ap- 

 peared also to interfere with the action of the rectum. 



"Examination of the Diseased Structures. — The organs 

 which Messrs. Gowing and Son sent, for inspection were the 

 generative organs, T^ith the bladder, kidneys, liver, and in- 

 testines, all of which, excepting the bladder, were normal. In 

 the interior of this viscus, the morbid changes were very 

 marked, the whole of the mucous membrane was intensely 

 congested, and in many places patches of extravasated blood 

 were firmly adherent to the surface. A quantity of dark-red
