400 INFECTIVE DISEASES. 



the lungs were affected with the disease in a miliary form. The 

 bacilU could not be distinguished from bacilli in sections of the bovine 

 disease. Giant cells were extraordinarily numerous, and in many 

 cases were densely packed with bacilli, so that they could be recog- 

 nised en masse under a low power. The bacilli were also distributed 

 in the tissue generally, but were much more numerous in the giant 

 cells. 



Tuberculosis in Doas. 



Peters described a case of tuberculosis in a pet dog, from eating 

 spiitum from a tubercidar patient. This is said to be a not 

 uncommon cause of canine tuberculosis. 



Tubebculosis in Oats. 



Nocard reported a case of tuberculosis in a cat from eating tuber- 

 cular sputum. The abdominal organs were diseased. Bollinger 

 has described two cases of miliary tuberculosis. MTadyean also has 

 described a case. The bacilU are very plentiful in the lung. A 

 minute examination of the individual micro-organisms by the author 

 did not reveal any distinctive character. 



TUBEECULOSIS IN SwiNB. 



The author examined the tubercular liver of a pig. The pig 

 was about six months old, and after suffering from cough and 

 emaciation, died. 



The liver had caseous nodules scattered throughout its substance, 

 some the size of a pea, and others larger. Tubercle bacilli without 

 distinctive characters were found on examination of sections ; but 

 it was in some parts of a preparation difficult to detect any bacilli, 

 and in other parts there were not more than five or six in the 

 field of the microscope. Tuberculosis in swine is said to be very 

 rare in America. 



Tuberculosis in Birds. 



Hens, guinea-fowls, turkeys, pheasants, and partridges, are sub- 

 ject to tuberculosis, and ostriches and other birds kept in confinement 

 may contract the disease. 



Tuberculosis in fowls appears to be introduced principally with 

 the food, the disease occurring commonly in the intestines and 

 liver.
