fication than in the ox, the older tubercles remaining in the 

 caseated condition or bursting and forming vomicae. A common 

 seat of casual tubercle in sheep is around the throat or on the 

 sides of the cranium or face. 



More frequently than in cattle, verminous affections (cesopha- 

 gostoma columbiana, and veuulosum in the bowels, stongylus 

 filaria and rufescens in the lungs, linguatula denticula in the 

 mesenteric glands) are mistaken for tuberculosis, hence the neces- 

 sity for a careful investigation into the nature of the neoplasm, 

 the presence of the tubercle bacillus, and the absence of the worms 

 and their eggs. Except in the case of the linguatula the lymph 

 glands are little affected by the worms. 



Dog and Cat. The lesions are often concentrated on the respi- 

 ratory or alimentary tract, but they have been noted also in the 

 pharyngeal glands, tonsils, posterior nares, serosae, liver, pan- 

 creas, spleen, nerve centres, ovary, uterus, testicle, epididymus, 

 tunica vaginalis, prostate, heart, aorta, bones and joints. They 

 follow the regular development of bovine tubercle, and caseation 

 and cretefaction are prominent features. These animals are especi- 

 ally liable to infection by eating the left victuals from the plate of 

 a consumptive owner, as well as by devouring consumptive prey, 

 and the primary lesions are to be looked for along the line of the 

 throat, bowels, liver and lungs. For the dog Cadiot records 

 caseating polypi and ulcers on the mucosa of the larynx, trachea 

 and bronchia, and Muller and Cadiot several cases of pharyngeal 

 caseating adenitis in the dog bursting externally and developing 

 intractable fistulae, having abundance of bacilli in the discharge. 

 These he attributes to expectorated virus from old-standing 

 tubercles in the chest infecting the pharyngeal mucosa and indi- 

 rectly the lymph glands. The infection entering with the food 

 and lodging in the follicles of the tonsils would act in the same 

 way, and infected wounds received in fighting must also be 

 quoted. Cats suffer from similar intractable sores, some of 

 which may be traced to a tuberculous origin. The lungs are 

 often extensively hepatized and of a general pale grayish color, 

 but the early miliary lesions, the caseating and cutaneous centres, 

 the vomicae often intercommunicating, the tuberculous bronchial 

 and mediastinal glands and the bacilli show the true nature. In- 

 testinal ulcers are common, especially on the agminated glands,
