 and cords, before referred to, throughout the whole gland, 

 they are in comparatively small numbers in the outer part 

 of the alveoli and meshes, and leave this portion, as it 

 were, open. (See figs. 97, 98.) This free space between 

 the gland-pulp and the trabecular stroma, occupied only by 

 retiform tissue, is called the lymph-channel or lymph-path, 

 because it is traversed by the lymph, which is continually 

 brought to the gland and conveyed away from it by 



lymphatic vessels ; those which bring it being termed 

 afferent vessels, and those which take it away efferent 

 vessels. The former enter the cortical part of the gland 

 and open into its alveoli, at the same time that they lay 

 aside all their coats except the epithelial lining, which may 

 be said to continue to line the lymph-path into which the
