468 DISEASES OF THE URINARY ORGANS. 



out a prodigious quantity of pus. The puncture cicatrised ; 

 V»ut in six months^ time a deep fistula had formed in it, 

 which, every time the horse moved, ejected a stream the size 

 of the finger of white grumous pus. Notwithstanding it was 

 twice laid open, the fistula would not heal, and the horse 

 sank. Pus was found effused in the abdomen. The right 

 kidney was four times its natural magnitude. Its pelvis, 

 greatly distended, contained about three pints of grumous 

 pus, communicating outwards through an opening in the 

 posterior border of the kidney, which led into the fistula 

 that had formed between the peritoneum and psoas muscles. 

 The left kidney was larger than common, and its pelvis was 

 distended with nearly a quart of limpid urine. The bladder, 

 shrunk and thickened in its coats, contained but very little 

 urine, and that sedimentous. 



Of Softening, a very satisfactory case is related in ' The 

 Veterinarian^ for 1828, by Mr. Cartwright : 



" Each kidney was found to be in a complete state of 

 putrefaction, of a light bluish colour : its texture so totally 

 destroyed that the finger would pass through any part of it 

 as through so much mud. The vessels of the kidneys did 

 not appear diseased as I drew them out of the diseased 

 masses." 



Hurtrel d^Arboval regards mortification as a more fre- 

 quent termination than suppuration; and gives the follow- 

 ing as — 



The Symptoms indicative of Mortified Kidneys: 

 Urinary discharges, brown or black, filamentous, and fetid ; 

 pulse small, irregular, intermittent ; recurrence of sweats, 

 and, these all at once ceasing, the patient falls, and in violent 

 convulsions expires. 



HYPERTROPHY. 



An instance of this, to an enormous extent, and proving 

 fatal, is related by D^Arboval. 



Of ENORMOUS Enlargement, a case is related by Mr. 

 Freemann, Y.S., Winchester, in ' The Veterinarian^ for
