470 DISEASES OF THE UllIxNAKY ORGANS. 



OF CONDENSATION, INDURATION, AND SCIRRIIUS. 



I have seen several specimens in wet preparations. The 

 following cases from D^Arboval^ in illustration of these 

 changes, are worthy our attention : 



" A horse suspected to have strained his loins, was for 

 three months under the treatment of an empiric. For the 

 first two he continued standing; at length he lay down, 

 never to rise again, and died in a complete state of marasmus. 

 In opening the body, M. Chouard discovered that the left 

 kidney, of its ordinary volume, had become cartilaginous. 

 Its pelvis contained a large glassful of limpid urine. The 

 right had also begun to undergo the same change, and had 

 become firmly adherent to the peritoneum. In the bladder 

 were found several stones about the size of peas : and one 

 within the left ureter. Here, therefore, existed urinary 

 calculi. But in the case which follows, nothing of the kind 

 was discovered : 



A horse, eight years old, strained his loins in descending 

 a steep declivity ; but in spite of the inconvenience it occa- 

 sioned him in going, continued his work for eight months 

 afterwards, at which time M. Chouard first saw him. He 

 had not lain down more than twice or thrice since the acci- 

 dent, and was now couched upon his hind parts like a dog. 

 The urine, which until now had passed frequently and in 

 small quantities, had become suppressed altogether. There 

 was obstinate constipation, and the patient appeared to suffer 

 violent pains in passing his dung. He was destroyed. The 

 left kidney, in a state of induration, liad become a carcino- 

 matous mass, of the size of a man's head, and about eight 

 livres in weight, in the centre of which was a nucleus of 

 suppuration. An aneurism, as large as the aorta, existed in 

 the renal artery of the same side. 



MELANOSIS.
