meshes. Thus the peripheral third or fourth of the 

 gland is subdivided by the septa and trabeculae, into 

 relatively large spherical or oblong compartments, while 

 the middle portion is made up of relatively small cylin- 

 drical or irregularly-shaped compartments (Fig. 60). 

 The former region is the cortex, the latter the medulla of 

 the gland. The compartments of the cortex anastomose 

 with one another and with those of the medulla, and 

 these latter also form one intercommunicating system. 

 The fibrous capsule, the septa and trabeculse are 

 the carriers of the vascular trunks ; the trabeculse 

 consist of fibrous connective tissue and of a certain
