tracts, and through the blood. It is usually possible in 

 secondary tuberculosis to demonstrate the original 

 focus, but in the case of tuberculous lymphatic glands 

 the source of infection is not always discoverable. 

 This has been explained by assuming that infection 

 may take place in utero and the bacilli lie dormant in 

 the lymphatic glands for varying periods after birth 

 (latent tuberculosis). The possibility has also been 

 suggested that the bacilli may penetrate a mucous 

 membrane, be carried to the nearest lymphatic gland, 

 and unfold their activity there. In the human subject 

 tuberculosis appears under various forms, presenting 

 clinical differences, but identical from the pathologic 

 standpoint. Since the discovery of the tubercle- 

 bacillus such diseases as scrofula, lupus vulgaris, 

 Pott's disease, many forms of chronic joint-disease, 

 and the anatomic tubercle have been proved to be 

 tuberculous in nature. The most frequent seats of 

 tuberculosis are the lung, the intestinal tract, the 

 lymphatic glands, the serous membranes, the bones, 

 the skin, the testicle, the epididymis, the brain, the 

 Fallopian tubes, the uterus, the spleen. Tuberculosis 

 is very frequent in the lower animals, attacking especi- 

 ally the domestic herbivora and fowls and wild 

 animals kept in captivity. In cattle the lesions take 

 the form of nodes and conglomerates, which, on 

 serous membranes, may be pedunculated (pearl- 

 disease). Histologically there is in bovine tubercu- 

 losis a greater tendency to the formation of fibrous 

 tissue than in the human form. The symptoms of 

 tuberculosis vary with the localization of the disease. 

 A few general phenomena are common to nearly all 

 forms, viz. : emaciation, loss of strength, anemia, 

 fever, and sweats. Amyloid degeneration may occur 

 in various organs in cases of the disease associated 

 with prolonged suppuration. In the diagnosis of 

 tuberculosis the demonstration of the presence of the 

 bacillus is of the highest importance. T., Acute 

 Miliary, an acute, febrile disease, characterized by the 

 formation of minute tubercles in great numbers in 

 various parts of the body. It is due to the discharge 

 into the circulatory stream of the constituent elements 

 of some tuberculous focus, scattering the bacilli through- 

 out the system. Three forms are usually described : 

 I. A general or typhoid form 2. One with marked 

 pulmonary symptoms. 3. One in which cerebral 

 symptoms predominate. T., Anatomic. See Tubercle, 

 Anatomic. T., Avian, tuberculosis affecting birds. 

 T., Bovine, tuberculosis as it occurs in cattle ; pearl- 

 disease. See Tuberculosis. T., Cerebral : 1. Tuber- 

 culous meningitis. 2. Tuberculosis of the brain itself. 

 T. cutis, tuberculosis of the skin ; lupus vulgaris is 

 the most common form. T., General Miliary. See 

 T. , Acute Miliary. T., Hematogenous [of the lung), 

 this may be a miliary tuberculosis, affecting both lungs 

 or a greater portion of one only, or it may be a localized 

 tuberculosis, characterized by the appearance of tuber- 

 cles in a limited area of the lung. T., Inoculated, 

 tuberculosis caused by direct inoculation of tuberculous 

 material. T., Intestinal, tuberculosis affecting the 

 intestinal tract. T., Laryngeal, tuberculosis of the 

 larynx. It is usually secondary to tuberculosis of the 

 lungs, but in rare cases appears to be primary. T., 

 Latent. See under Tuberculosis. T., Meningeal, 

 tuberculosis of the cerebral or spinal meninges. The 

 tubercles are scattered along the course of the blood- 

 vessels. T., Miliary, tuberculosis characterized by the 

 deposit of miliary tubercles in the viscera. T., Para- 

 sitic, tubercular growths produced by parasitic nema- 

 todes. T., Pseudo, a disease producing lesions similar 

 to those of tuberculosis, but due to a pleomorphic or- 

 ganism, the Cladothrix asteroides (Eppinger). T., 



Pulmonary, tuberculosis of the lungs. T., Rena 

 tuberculosis of the kidney. T., Surgical, tuberculos 

 of parts amenable to surgical treatment. T., Urogeni 

 tal, tuberculosis, apparently primary, of the genit< 

 urinary tract. T. verrucosa cutis. See Verruca necn 

 genica. T. zobglceica, also known as pseudo-tube 

 culosis. A disease of guinea-pigs, rabbits, lambs, an 

 horses, which is characterized by cheesy nodules. Tl 

 cause is a pleomorphic bacillus forming zooglea masse:
