one entering a Malpighian 

 corpuscle and breaking up 

 into the capillaries of the 

 glomerulus. 



On its way towards 

 the external capsule, the 

 interlobular arteries be- 

 come greatly reduced, and 

 finally enter the capillary 

 network of the most peri- 

 pheral part of the cortex ; 

 but some of these arterioles 

 may be also traced into the 

 outer capsule, where they 

 become connected with the 

 capillary networks of this 

 latter. The efferent vessel 

 of a Malpighian glome- 

 rulus at once breaks up 

 into a dense network of 

 capillary blood - vessels, 

 which entwine in all pos- 

 sible directions the urinary 

 tubules of the labyrinth. 

 This network is continued 

 with that of capillaries of 

 the medullary rays, the 

 meshes being there elon- 

 gated, and the capillary 

 blood-vessels, for obvious 

 reasons, more of a straight
