OF ALBUMINURIA. 21 



a little serum oozing out, but no pus ; there was a 

 white deposit in diffused patches, and a few small 

 scattered spots over the whole cortical part; the 

 tissues of the organ were rather fluid and friable ; 

 there was a minute quantity of dirty, dark, brownish 

 urine. 



These appearances correspond very closely with 

 those observed in a rabbit in which I exposed the 

 kidney and passed a thread under the renal vein, 

 allowing it to remain there with the view of inducing

slow obliteration of that vessel and a simultaneous 

 congestion of the kidney. It died nine days after- 

 wards, and on examination, the kidney operated on 

 >vas, if anything, rather smaller than natural ; its 

 surface seemed to want the smooth convexity of the 

 healthy organ, as though its bulk had been recently 

 diminished; on the exterior, and diffused through 

 the substance of the cortical tissue, were irregular 

 white patches of lymph, and the remains of several 

 ecchymoses, the colouring matter of which had been 

 partly absorbed. The other kidney was considerably 

 congested, and the urine in the bladder moderately but 

 distinctly albuminous, both heat and nitric acid being 

 applied. 



These may be looked upon as the appearances 

 which would generally result in cases where the 

 inflammation has been very acute, and the patient 

 has lived long enough for absorption to have dimin- 

 ished the bulk of the congested organ, constituting 

 as it were the transition stage between the enlarged 

 and engorged state of the kidney on the one hand, 

 and its diminution and atrophy on the other. Were
