    Finally, we must include among the circumscribed in- flammatory processes in the conjunctiva the various forms of infectious granular tumors, chief among which is 12. Tuberculosis. Tuberculosis is always chronic, and occurs either inde- ])cndently or in association with lupus of the face. In nearly every case the nature of the disease manifests itself by swelling, and occasionally by cheesy and puru- lent degeneration of the preauricular and submaxillary lymph-glands. Sometimes the process is purely local, or at least no signs of tuberculosis are found in othei' organs of the body. In other instances the patient exhibits signs of a general tubercular infection in lungs, lymphatic glands, joints, etc. Occasionally the proce.ss begins in the nose and the infection is carried to the eye through the lachrymal duct. In the conjunctiva H appears first as a moi'c or less circumscribed focus of tubercular infiltration, or as a single nodule, or the tubercles are scattered over a larger area. The tuberculous growth is more or less completely enclosed in a capsule of granulation-tissue, which materially increases the extent of the focus; neither tubercular nodules nor bacilli are to be found in the ex- cised growth. These arc only found in the deeper layers of the hypertrophied tissue, if they are found at all ; the bacilli are never ju’esent in large numbers any more than in other forms of chronic tuberculosis. The tubercles ra])idly become cheesy and break down, and the conjunctiva becomes covered with tuberculom nlcei'swlih purulent or cheesy floors and surrounded by granulation-tissue. In the intervals between the ulceus, which may be cpiite numerous if the process becomes extensive, miliary tubercles are occasionally seen, and .sometimes true follicles, resembling trachomatous granu- lations. In ])rotractcd cases the entire palpebral conjunc- tiva of both lids eventually becomes di.seascd, gradually the process encroaches on the j)upillary region, and the
