culosis or of extension from the pericardium of endocardium. In 

 the N. Y. State Veterinary College Museum is a cow's heart, 

 greatly enlarged, and completely invested and invaded by tubercle 

 several inches thick. 



Tuberculosis of the Mouth and Throat. Tubercles sometimes 

 form in the tongue causing nodular swelling, with a caseated 

 centre. Much more frequently they attack \.\\& pharynx or larynx 

 with the formation of nodular necrotic swellings, followed by 

 ulcers and the implication of the adjacent lymph glands. The 

 glands are liable to be invaded through the tonsillar and other 

 follicles of the faucial and pharyngeal regions, which like the 

 solitary and agminated glands of the intestines form excellent 

 culture vessels. The glands most frequently attacked are the 

 retro-pharyngeal, but the later ahpharyngeal, the intra-parotidean 

 and sub-maxillary lymph glands occasionally suffer. They often 

 become indurated, yet the formation of abscess-like sacs is not 

 uncommon especially in the retropharyngeal. 



Gastro- Intestinal, Peritoneal and Mesenteric Tubercle. Tuber- 

 cles of the interior of the stomachs are rare, though they are 

 frequent on the peritoneal surface of the first three stomachs, as 

 rounded, subserous nodules varying in size from a pea upward. 

 The mucosa of the small and large intestines may suffer, by 

 preference in the seats of the solitary or agminated glands, and 

 the resulting ulcers may extend in the lines of the lymph vessels 

 from the convex to the attached border of the .gut. The small 

 greenish caseated and calcified nodules on the intestines, which are 

 so often mistaken for tubercles, are the degenerated cysts of the 

 cesophagastoma. Tuberculosis of the mesenteric lymph glands 

 is much more common, the successive stages being essentially 

 like that seen in the bronchial glands. Besides these the surface 

 of the mesentery, omentum and abdominal parietes often becomes 

 the seat of congestion, exudation and cauliflower-like neoplasms 

 or grapes, as already stated of the pleurae. In a certain number 

 caseation or cretefaction may be detected. 



Liver Tuberculosis. The liver is greatly exposed to tubercu- 

 losis as the single destination of all the blood from the gastro-in- 

 testinal tract. Tubercles also form on its surface by direct 

 infection from the peritoneum. The hepatic tubercles are often 

 very large and numerous, adding greatly to the bulk and weight
