. Compendium of histology. Histology. L ] 'MPHOW OR GA NS. 121 sents a reticulum with very narrow meshes, in the interspaces of which one, or, at the most, a few lymphoid cells find place; and let us not forget that the pulp-tubes possess, su- perficially, the same reticular character, covered by an en- dothelium consisting of separate, uncemented Fig. 113.—From the spleen of the hedgehog ; a, pulp, with the intermediate currents ; h, fol- licle ; c, boundary layer of the same : g, its capillaries ; e, transition of the same into the interme- diate pulp-current; f, transverse section of an arterial branch, at the border of the Malpighian corpuscles. If we adhere to this previously described textural condi- tion, the lacunar capillary blood current, which arises after the loss of the capillary walls, will present no further con- siderable difficulty. As the failing branch of a drying brook wanders at last between the pebbles of its bed, slender and scanty, so is it with these finest blood currents. The lym- phoid cells resemble the pebbles. Still, the blood current contains cellular elements and the red blood corpuscles in excess. A portion of the latter slip through with their pliable, smooth surface ; others stick fast. For our colored elements, however, as we have already learned, movement is life, rest is death. Thus are explained those numerous corpses and fragments of the colored blood cells in the spleen, which we mentioned above (p. 119). Something additional is also satisfactorily explained by this. The closely crowded amoeboid lymph cells are capable of taking up into themselves the imprisoned blood corpuscle 6.
