Elements of pathological anatomy . ing cut, they slightly creak under theknife, the section presenting a homogeneous aspect. The fibrous envelope isvery dense and thick ; and both its own vessels and those which are distributedto the proper parenchymatous tissue are tortuous, knotty, and dilated. Theabsorbents entering into the composition of these bodies are also more or lessenlarged, though, occasionally, their cavity is so much diminished as to renderit impossible to inject them. The disease sometimes passes into suppuration,the parenchymatous structure being entirely destroyed, the thickened and in-durated capsule being the only part that is left. The pus in such cases is semi-concrete, and often remarkably offensive, apparently from its long sojourn inthe parts. Chronic inflammation leaves these glands sometimes in a state of hypertro-phy?, as in Fig. 73. In this condition, they may be perfectly white or grey-ish, or else they may acquire a light brownish or yellowish tint; their con- 252 V 111 s. Fig sistence, also, is trequently much augmented, and cases occasionally occur inwhich they are of a dense, gristly hardness, like scirrhus. The glands mostliable to be thus affected are the mesenteric, bronchial, internal iliac, inguinal, and cervical. I have a prepara-tion, taken from a child three years of age,in which the mesenteric ganglions, all mat-ted into one general mass much larger thana foetal head, are of a bluish grey color,homogeneous, and of the consistence ofcartilage, each one grating sensibly underthe knife. Many of them are as large asan orange, and they all have a very thick,indurated capsule, of the same tint verymuch as the altered parenchymatous sub-stance. Hypertrophy of the lymphatic glandsmay arise from irritation, seated originallyin their own tissue, or it may proceed from irritation propagated to themfrom the surrounding parts. In the glands of the mesentery, it is commonlycaused by irritation of the bowels, especially of the
