of masses of a delicate trellis-work of adenoid tissue, packed with 

 nucleated protoplasmic cells, called lymph corpuscles, the com- 

 bination making what is known as lymphoid tissue. (Figs. 83, 

 84 and 85.) These masses of cells and their delicate supporting 

 reticulum are inclosed in a fibrous case or capsule, from which 

 branching trabeculse pass into the gland and separate the masses

of lymphoid tissue from one another. Through the convex side 

 of the capsule the lymph channels enter and pour their contents. 

 The lymph then flows through irregular paths, which lie between 

 the lymph follicles next to the capsule and trabeculse, and lead 

 to the concavity of the gland from which the efferent vessel 

 escapes.
