lateral, rendering the animal incurably sterile as well as a 

 peril in a breeding or milking herd. The pus from tuber- 

 culous pyosalpinx escapes through the uterus and cervix to 

 the vagina, to constitute a very serious menace to the bull. 

 (3) Uterine tuberculosis is the commonest and most dan- 

 gerous type of genital tuberculosis. It is supremely dan- 

 gerous to the bull when copulating with the affected animal. 

 The discharges resulting from the tuberculous uterine ca- 

 tarrh soil the vulva, tail, thighs, and ultimately the udder, 

 and contaminate the milk. Thus the milk becomes intensely 

 dangerous for calves, for other animals, and for man. In 

 its peril to animal and human health, uterine tuberculosis 

 vies with tuberculosis of any other organ. Uterine tuber- 

 culosis is quite variable, showing three somewhat separable 

 types : 



(a) Peritoneal uterine tuberculosis with extensive pelvic 

 adhesions, as shown in Figures 104, 105, 106. 



(b) Tuberculosis of the glandular structure of the uterine 

 mucosa, as shown in Figures 105, 106, 107, 108, 109. 



(c) Tuberculosis of the epithelial layer of the mucous 

 membrane, as shown in Fig. 110. 



No clear line of demarcation can be drawn between the 

 three types, but in most cases one of the three groups of 

 lesions predominates. 



In uterine tuberculosis there is generally a persistent, ob- 

 stinate uterine catarrh. In some cases the catarrhal dis- 

 charge is inconspicuous. Douching the uterus may reveal 

 very little pus. In some cases of tuberculous uterine ca- 

 tarrh, uterine douches affect the catarrh favorably for a 

 time, but permanent relief I have not observed. Where 

 there have been apparently favorable results from douch- 

 ing, misleading the practitioner as to the nature of the 

 malady, limited observation indicates that copulation sets 

 the infection aflame. In such cases as illustrated by Fig- 

 ures 108 and 109, the catarrh is profuse, but not generally 

 fetid. Like tuberculosis of the oviducts, uterine tuberculo- 

 sis is usually, if not always, symmetrical, or bicornual. 

 Generally the uterus contracts extensive pelvic adhesions.
