closer arrangement than in the cortex ; spaces (fig. 294, 6) are 

 left within those anastomosing cords, in which are found 

 portions of the trabecular meshwork and the continuation of the 

 lymph-path. 



The lymph enters the gland by several afferent vessels, which 

 pierce the capsule and open into the lymph-path ; at the same 

 time they lay aside all their coats except the endothelial lining, 

 which is continuous with the lining of the lymph-path. The

efferent vessels begin in the medullary part of the gland, and are 

 continuous with the lymph-path here as the afferent vessels were 

 with the cortical portion ; the cndothelium of one is continuous 

 with that of the other. 



The efferent vessels leave the gland at the hilus, and generally 

 either at once, or very soon after, join together to form a single 



vessel. 



Blood-vessels which enter and leave the gland at the hilus are 

 freely distributed to the trabecular tissue and to the lyrnphoid 

 tissue.
