clothing of an attendant who came from another State 

 about one month before the disease was first noticed. 



No ulcers were found on the vaginal membranes of 

 the Angus, but there was evidence of extensive pre- 

 vious ulcerations. The Angus was supposed to have 

 contracted the disease first, gradually acquiring a re- 

 sistance for the microbe, and was on the way to recov- 

 ery. In this case the disease yielded readily to antisep- 

 tic treatment. 



Tlie Shorthorn probably contracted the disease from 

 the Ang-us, though a steer occupied a stall between the 

 two in the barn. This heifer was at the climax of an 

 acute attack. There was ecchymosis of the mucf.us 

 membrane of the vagina as for farward as could be seen, 

 with extensive exfoliation of the epithelium aud ulcer-

 and heavily turbid. 



The vagina was irrigated with 2 per cent, creolin 

 solution and packed with iodoform gauze once per day 

 for the course of two weeks. 



This discharge soon ceased, but a kind of stimulation 

 of the genitals, probably irritation, continued as the 

 animal was frequently in heat. 



Oestrum, or lieat, recurred every seven to ten days, 

 manifested by a swollen and loose condition of the 

 vulva. The discharge was somewhat profuse and yel- 

 lowish, translucent instead of transparent. 



The ulcers gradually disappeared from the visible 

 mucous membranes and the application of medicine was 

 discontinued. About two ^^•eeks later the animal was 

 brough up for final examination and dismissal. But it 

 was found that another crop of ulcers had appeared. 

 This time the catarrh was much less severe, and the 

 visible ulcers were very few, limited in size and closely 

 resembled the one on the prepuce of the inoculated 

 rabbit. 



The animal was subjected to another course of treat-
