Respirations may be labored or accelerated according to 

 the advancement and intensity of the disease. The pulse 

 and temperature at times will rise above the normal ; but 

 will remain normal most of the time. 



If the pleura is involved, the ear applied to the chest may 

 detect friction sounds which are most distinct near the end 

 of inspiration. 



In tuberculosis of the stomach, intestines or mesentery, 

 digestion is deranged and irregular. Young animals whose 

 chief food is milk may have tuberculosis of the bowels or 

 mesentery; this is manifest by indigestion, bloating and 

 persistent diarrhoea; it may lead to general tuberculosis, 

 involving the lungs and many other parts of the body. In 

 older animals the appetite is capricious, digestion is im- 

 paired ; the animal may bloat slightly after meals; have 

 attacks of indigestion, and finally persistent and uncoutrol- 

 able diarrhoea will appear. la some cases constipation will 

 alternate with periods of diarrhoea or "scouring." 



Tuberculosis of the peritoneum is difficult to determine 

 in the living animal. 



Tuberculosis of the uterus and ovaries is usually accom- 

 panied by sterility and long and frequent periods of heat 

 (nymphomania). 



When the udder is tuberculous it is confined usually to 

 one quarter ; yet it may involve each quarter. The diseased 

 quarter is hard, insensitive to pressure and does not yield 

 much milk. In rare instances the tuberculous udder may 

 contain an abscess. Sometimes the cheesy or yellow tuber- 

 cles erupt into the milk cavities and canals ; thus the 

 bacilli become mixed with the milk. Infrequently the sub- 

 maxillar}'^ glands enlarge, soften, erupt and discharge a 

 cheesy yellowish matter. This might be mistaken for actin- 

 oflaycosis. 



The surface lymphatic glands at the base of the ear, in 

 front of the shoulder, in front and behind the udder, in the 

 groins, in front of, and above, the stifle, may be detected at 

 first as hard nodular swellings ; in the later stages as large 

 soft swellings.
