of the nteriis wliicli have become transformed into knotty struc- 

 tures the size of a man's arm. The Fallopian tubes may present 

 twisted strands as thick as a finger and occasionally the uterus 

 is transformed into a large firm ball (Hess) . Cows thus affected 

 do not conceive but are frequently in heat, although sexual desire 

 vanishes as the disease advances. Tuberculosis of the vagina 

 and of the vulva, which is very rare, manifests itself in the 

 appearance of small yellowish nodules and erosions (Fischer) 

 or tumors as large as peas and ulcers wdth raised borders. 

 There may also be observed a purulent discharge, hypersensi- 

 tiveness and swelling of the lips of the vulva and enlargement 

 of the perineal lymph glands. Hess observed a case of tuber- 

 culosis with thickening of the labia of the vulva resembling

elephantiasis. Fischer referred to this form as lupus liyper- 

 trophicans of cattle. 



Since the superficial lymphatic glands (Fig. 85) in the 

 pharyngeal and cervical regions become primarily infected and 

 the remaining glands become involved in most cases as a result 

 of tuberculosis" of neighboring organs the determination of in- 

 fection of the former glands is of special importance in the 

 diagnosis of this disease. Large tumors, attaining to or ex- 

 ceeding the size of a man's fist are now and then found in one 

 or several of the following locations, viz., intermaxillary space, 

 behind the ascending portion of the inferior maxilla in the sub- 

 parotid region, on the side of the neck above the jugular furrow, 

 anterior to the scapula, at the inside of the elbow, in the pre- 

 erural and inguinal regions, in the flank, at the superior border
