LYMPHATIC GLANDS.

(p. 242). Pervading all parts of it, and occupying the alveoli 

 and trabecular spaces before referred to, is a network of the 

 variety of connective tissue termed retiform tissue (Fig. 98), 

 the interspaces of which are occupied by lymph-corpuscles. 

 The corpuscles are arranged in such a way, that while in the 

 centre of the alveoli and of each mesh they are so crowded 

 together as to be, with the retiform tissue pervading them, a 

 consistent gland-pulp, continuous in the form of the nodules 

 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.

A small portion of medullary substance from a mesenteric gland of the ox (mag- 

 nified 300 diameters), d, d, trabeculse ; a, part of a cord of glandular substances from 

 which all but a few of the lymph-corpuscles have been washed out to show its sup- 

 porting meshwork of retiform tissue and its capillary bloodvessels (which have been 

 injected, and are dark in the figure) ; b, b, lymph-sinus, of which the retiform tissue 

 is represented only at c, c (after Kolliker). 



(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
