In children the lymph nodes, serous membranes and the bonesare most frequently infected. Gross Pathology.—The characteristic lesion is the miliary tu-bercle. This is a gray, semitranslucent, slightly elevated (if su-perficially located) nodule varying in size from a point scarcelyvisible to the naked eye to 2 mm., which merges into the sur-rounding tissue (can not be peeled out). The second form oftuberculous lesion is an infiltration of the tissues with epithelioidcells and other cells characteristic of the tuberculous process, butwithout forming distinct tubercles. When caseation sets in, thelesions become yellow (yellow miliary tubercle). (Figs. 62 and63.) Minute Anatomy.—The bacilli (or their toxins) first cause pro
