animals in question. I have never seen it occur on courses 

 covered with horse dung, like that at Calcutta ; or on those laid 

 down with tan, like that at Cawnpore, when Honorary Secretary of 

 the Eaces at that station. Colonel John Anderson, A.V.D., was 

 the first to draw my attention to this cause of inflammation of the

SYMPTOMS.— Heat and tenderness of one or both testicles, with 

 more or less lameness in some cases. Matter (pus) may form at 

 the seat of injury, and watery fluid (serum) may accumulate at the 

 lower part of the scrotum.
