 in the sheath, usually in the ox or steer, seldom in 

 the bull. I was called to a well-marked case of 

 this trouble, which I will give as an illustration. 

 The patient was a three-year-old steer which was 

 noticed for some time to have a swelling at the end 

 of the sheath, which gradually increased in size. 

 One day the animal seemed to move stiff and re-

 with its back arched, breathing faster than nat-

 be in distress. I noticed that the sheath was swol- 

 len its entire length, and on examination I also
