IN THE KIDNEY. 41 



application of the ligature. The urine in the blad- 

 der was very slightly albuminous. On dividing the 

 left kidney, the lining membrane of the pelvis was 

 rendered prominent by the deposition beneath, or 

 external to it, of a quantity of clear lymph in which 

 the larger branches of the vein were imbedded. 

 There was no appearance of lymph in the cavity of 

 the pelvis. The right kidney weighed 42 grs.; the 

 left, 73 grs. 



Exp. 4. In tying the vein of a strong full-grown 

 rabbit, the coats of the vessel were slightly lacerated, 

 so that a little blood continued to ooze out by the 

 side of the ligature. In this state the organ was 

 returned, and the animal killed at the end of an 

 hour. Some urine had escaped through the urethra; 

 but on laying open the bladder, it was found to con- 

 tain a scruple, by weight, of clear pellucid lymph, 

 which was semi-fluid when first examined, but co- 

 agulated more firmly on exposure to the air. The 

 right kidney weighed 100 grs.; the left 130 grs. 



Exp. 5. A middle-sized animal, in tolerable con- 

 dition. The left renal vein was tied, and then punc- 

 tured with a fine needle on the renal side of the 

 ligature, so that some blood escaped in a fine jet. 

 The organ was then returned within the walls of the 

 abdomen, and the animal killed at the end of an 

 hour. The bladder contained about two drachms of 

 bloody urine, which held suspended in it a coagulum 

 of fibrine. This latter was reddened only at one 

 point ; the rest of it being unstained by blood. The 

 pelvis of the kidney also contained a small quantity
