52 EXPERIMENTS ON THE KIDNEY. 



disease of the kidney, thus furnishing additional evi- 

 dence of the influence of renal congestion in producing 

 many of the most characteristic phenomena of that 

 disease. He states conclusively, " It is therefore no 

 longer doubtful that the obstruction of the current 

 of venous blood in the kidneys produces, as a conse- 

 quence, the passage of albumen, fibrine, and, finally, 

 also of blood itself, into the urinary passages." 

 He also confirms my experiments as to the similar 

 changes in the composition of the urine effected by 

 an increased determination of blood to the renal 

 artery : "By tying the aorta, and at the same time 

 destroying a kidney, a constant transmission of con- 

 siderable quantities of albumen into the urine is 

 produced." He concludes, by expressing an opinion 

 that, " In the explanation of pathological phenomena, 

 these facts ought to be taken into careful considera- 

 tion."*)
