permanent flakes. The right kidney weighed 20 grs. ; 

 the left 40 grs. 



Exp. 2. The same operation was performed on a 

 rabbit of similar size and condition, which was killed 

 at the end of half an hour. A smaller quantity of 

 urine was found in the bladder, which, when tested 

 by the same re-agents presented a more distinct 

 flakiness. Weight of the right kidney, 26 grs. ; of 

 the left, 51 grs. 



Exp. 3. A small weak animal was killed at the end 

 of half an hour after ligature of the left renal vein. 

 There was no urine in the bladder ; the ureter was 

 not examined. The right kidney weighed 26 grs. ; 

 the left, 50 grs. 



Exp. 4. An animal of middle size, and in mode- 

 rate condition, was killed ten minutes after ligature 

 of the vein. There was about a drachm of urine in 

 the bladder, which was highly albuminous. The 

 right kidney weighed 35 grs. ; the left 70 grs. 



Exp. 5. The left vein and ureter being tied, in a 

 young healthy rabbit, the animal was killed at the 

 end of six minutes. The ureter being first carefully 

 wiped, and then divided, the urine contained in it 

 was allowed to drop on a watch-glass, and on being 

 tested with nitric acid, it formed a solid clot. There 

 was a slight appearance of coagulated lymph in the 

 pelvis of the kidney, and a more copious effusion 

 was found beneath its lining membrane. The blad- 

 der contained a drachm of urine, which was not 

 albuminous. The right kidney weighed 25 grs.; 

 the left 50 grs. 



Exp. 6. The left renal vein of a middle-sized
