ADDENDA TO THE DISEASES OF THE KIDNEYS. 369 



In the dog, the anatomical alterations of the kidney are : the 

 waxy consistence, paleness, dryness, and anemia of theeortical paren- 

 chyma, increase in size and hyaline tumefaction of the glomeruli, 

 and finally the presence, in the loops of the uriniferous canaliculi, 

 of homogenous casts of dull appearance and but little refraction. 



Subjected to the test of methyl-violet, the affected tissue becomes 

 of an intense purple ; treated with an iodated aqueous solution, it 

 becomes mahogany red ; this latter coloration is transformed into 

 steel blue under the influence of sulphuric acid. 



The symptoms observed by Rabe were subcutaneous œdema, espe- 

 cially marked upon the legs ; also ascites, albuminuria and uremic 

 accidents : vomitings, paralytic weakness, coma, lowering of the 

 general temperature. Cardiac hypertropy has not been observed. 



Concerning the treatment of the amyloid kidney, it is the same 

 as that of chronic nephritis, with which it is always confounded 

 during life. 



Tumors of the kidney are rare. In the dog and cat, they may 

 be recognized through abdominal palpation. We have found in 

 ^ the kidney : carcinoma, sarcoma, melanoma, adenomyoma, sarco- 

 myoma, and rhabdomyoma. In the majority of cases the diagnosis 

 is not made except at the autopsy ; during life we only observe 

 hematuria, sensitiveness of the renal region, and troubles of the 

 urinary secretion. The treatment would consist in extracting the 

 -diseased kidney.

Hemog'lobinemia of the Horse. 



CONGESTION OF THE KIDNEYS, AZOTURIA, BLACK STRANGURY, 

 HEMOGLOBINURIA, CONGESTION OF THE SPINAL CORD. 



Hemoglobinemia, as indicated by the expression itself, is not a 

 disease of the kidney. Under the influence of its various causes, a 

 secondary nephritis may accompany it, but this fact does not bring 

 it closer to the renal affections. Strictly, it ought to be described 

 in the article on Diseases of the Muscles. Our reason for studying 

 it here is because the practitioner usually seeks black strangury" 

 among the diseases of the kidney," and because one of its im- 

 portant symptoms — hemoglobinuria — is related to this group ; more- 

 over, we have decided not to separate this affection of the horse
