A large number of the meshes- 1880.] Lee-Fenger, Select Topics of Modern Surgery. 469 contain two, three or more small lymphoid cells or nuclei, manyof which are highly refracting. Outside of this giant cell reticulum we find the peripheral partof the tubercle consisting of the (o) lymphoid reticulum or smallcelled tissue of adenoid-like structure. The meshes of thisreticulum are narrow, long, oval, or spindle-shaped spaces, theirlong diameter being perpendicular to the radius from the centerof the tumor. They are filled entirely with innumerable small,round more or less refracting cells or Fig. 2.—Young adenoid tissue surrounding the miliary tubercles—fromcase of excision of knee-joint: a, Tissue with large round meshes; b, Tissuewith oval, narrow meshes; c, Transverse section of a small vein tilled withblood corpuscles; cl, Longitudinal cut of a small vein at filled with blood,at / empty, showing the nuclei of the endothelial cells; g, The outerwall of the vessel forming the reticulum of the interstitial net-work (framework.) The surrounding tissue, of recent growth in which the tuber-cles are imbedded, has, in its young state, invariably all thecharacteristics of the so-called adenoid or lymphoid structure,(as is shown in Fig. 2.) It derives its name from its similarityin structure to the lymph-glands, or the tonsils, or the adenoidtissue as we find it along the whole of the intestinal tract, or theadenoid vegtations from the naso-pharyngeal cavity. It consistsof a fine connective tissue net-work with round or oval meshes,fil
