of all cases of generalised tuberculosis involve the uterus, while Lungwitz found 

 this organ involved in 152 out of 264 cases of pearl disease of the peritoneum. 

 In far advanced cases the afl'ected uterus may weigh 40 kilograms (Moebius). 

 According to Fischer's investigations the majority of cases spread from the rallopian 

 tubes to the uterus. This seems to be true even when the lesions of the uterus appear 

 more advanced. 



Tuberculosis of the udder is usually characterized by the 

 ]jreseuce of large firm tumors witli cheesy coutents and numer- 

 ous small tubercles scattered through the intervening tough 

 connective tissue (P'ig. 83). As a rule either one or both pos- 

 terior quarters and the adjacent regions of the anterior quarters 

 are affected. The diseased part which is usually enlarged, but 

 sometimes atrophied, is separated from the normal portion by 

 a well marked sinuous line of demarkation. The walls of the

milk ducts may contain tubercles or they may be enormously 

 distended and enclose masses of cheesy detritus and flaky or 

 curdled milk. Some of the veins of the udder may be found 

 obliterated with blood clots in wliich colonies of tubercle bacilli 

 may here and there be demonstrated (Bang). In recent embolic 

 infection the lobules of the affected quarters are swollen and 

 their gray substance sprinkled with yellow points or streaks 

 while the intervening connective tissue is riddled with minute 

 tubercles and clieesy foci ]-anging in size from that of a lentil 

 to a pea (Bang, Moser). In advanced cases the affected quarter 

 may have been transfoi'med into a firm tumor containing cheesy 

 masses enclosed by tough fibrous connective tissue. The super- 

 mammary glands are alwavs involved when the udder is af-
