some complication, which modified in some measure the renal func- 

 tions. As is to be expected after an operation as complex as the 

 transplantation in mass, various accidents occurred ; hydronephrosis, 

 intestinal compression by peritoneal adhesions, volvulus, phlegmon, 

 puerperal infection, compression of the renal veins by organized 

 hematoma of the connective tissue, which were the direct or indirect 

 causes of death in these animals. However, in two experiments the 

 functions of the kidneys seem to have been for a certain time almost 

 completely normal. The color of the urine was yellow, generally, 

 or often less dark than the normal urine of the cat. Its reaction 

 was acid. Its quantity for twenty-four hours oscillated between 

 120 and 1 60 c.c, but it might be, exceptionally, 25 and even 15 c.c, 

 or in another case, 215 or 255 c.c. for twenty-four hours. The 

 density was very far from constant; generally it oscillated between 

 1. 018 and 1.030, going sometimes as high as 1.035 ^^^ i-05i- 

 Among the abnormal constituents of the urine the presence of albu- 

 min only has been looked for. In some cases there was a little 

 albumin during the first days, ranging from 0.50 to 0.25 for 1,000 

 c.c. In other cases the albumin disappeared about one week after 

 the operation. 



The general condition of the animal can be used, in some meas- 

 ure, to indicate the perfection of the urinary elimination. As long 

 as no complications were present the animals lived as normal cats 

 do, without presenting any symptoms which could be considered as 

 produced by renal insufficiency. When general complications oc- 

 curred the cats reacted against them in normal ways. In one case, 

 the animal was in apparently normal condition four days after the 

 operation. She walked about the room, played and ate a great deal 

 of raw meat. Her condition remained excellent for several weeks. 

 Twenty days after the operation she was in good health, had glossy 

 hair, was very fat, ate with appetite all kinds of food and urinated 

 normally. There was, however, albumin in the urine, and slow and 

 progressive enlargement of the kidneys took place, which showed 

 that she was not in an entirely normal condition. It remained in 

 excellent health until the twenty-ninth day after the operation. 

 Then gastro-intestinal symptoms appeared, and death occurred on 

 the thirty-first day after the operation.
