The vascular pathology of the kidney in both the diuretic 

 and anuric animals consists primarily in an acute congestion 

 which is most marked at the glomerulus. The glomerular 

 capillaries are engorged with blood and fairly uniformly fill 

 the space enclosed by the capsule. Occasionally between the 

 capillary tufts and the capsule there has been observed a 

 small quantity of granular material. This has never been 

 present in such an amount as to compress the capillaries. 

 Blood cells have not been demonstrated in this material. 



The capillaries have failed to show any histological evi- 

 dence of chanees of a degenerative character. The interest-

 The figure shows the absence of acute swelling of the epithelium. 

 The epithelium is not necrotic. The lumen of the tubules is not en- 

 croached upon by the epithelium. The glomerular vessels are engorged 

 with blood and fairly uniformly fill the capsular space. The renal 

 vessels were responsive to peripheral stimuli. The figure represents 

 the kidney of an animal that remained diuretic following Grehant's 

 Anesthetic. 



ing type of vacuolar degenration of the capillary walls, first 



described by Christian (5), has not been present in this series 



of animals. Neither have the more extensive structural 



changes been observed which have been described by Chris-
