(Johnston*). Each of these branches forms a series of anasto- 

 mosing capillary loops whose convexity is directed away from the 

 entering artery. The capillary loops reunite, in a similar manner,

FIG. 282. FROM THE CORTICAL LABYRINTH OF THE HUMAN KIDNEY. 

 A large Malpighian body is in the center of the figure. At its upper border are sev- 

 eral sections of distal convoluted tubules. The great majority of the tubules shown are 

 from the proximal convoluted portions, a, a portion of a glomerulus ; J-J, parietal layer 

 of Bowman's capsule; c, proximal convoluted tubules; d, just within this point is a 

 transection of a junctional tubule having relatively low and clear epithelium and a 

 broad lumen. Hematein and eosin. Photo, x 135. 



to form the efferent vessel, which leaves the glomerulus in com- 

 pany with the afferent ; but, once out, they soon part company, the 

 efferent vessel breaking into a second capillary plexus about the 

 neighboring tubules. Within the glomerulus the capillaries are
