Tubercle
a small tuber; a warty usually taking the shape of minute round excrescence; in pathology, a growth testines, larynx, etc., of persons of scrofumasses, and developing in the lungs, inlous constitution. It is described by pathologists as being of two kinds, the gray or miliary, and the yellow or crude; but the latter is, strictly speaking, a secondary form of the former. Gray, or miliary tubercle, is "a grayish-white, translucent, non-vascular body, of firm consistence and well-defined spherical outline, let seed. Though in its earlier stage it is outline , usually about the size of a miluniformly translucent, its central portions quickly become opaque and yellowish, owing to the retrograde metamorphosis of its component elements. In structure tubercle, like the other lymphomata, consists of lymphatic cells tained in the meshes of a very delicate reticulum. The cells are mostly round, or roundly oval, colorless, transparent, and slightly granular bodies, much resembling lymph corpuscles; and, like these, varying considerably in size." con-
