DISEASES OF THE DEER. 343 



three inches long, and the protuberance an inch thick, and really 

 has an alarming appearance, a deep central incision an inch or 

 more long has always proved effectual. But as only the tame 

 deer, which can be caught, can be treated, all the wild Virginia 

 Deer which have been attacked, so far as I know, have died. In 

 the early part of my experiments, this disease was much more 

 prevalent than in later years, and so I conclude that those more 

 remotely descended from the wild stock are the least liable to it. 

 It only attacks the adults, or those more than two years old. 



Two of the Ceylon adult does have been attacked with it, both 

 of which were dropped in my ground. They were too wild to 

 be taken and treated, but to my surprise both recovered, which 

 has I think never happened with the Virginia Deer. I have no 

 account that this disease has ever been observed among the wild 

 deer of the forests ; certainly, I have never seen one afflicted with 

 it. 



I have never observed any syfnptoms of it either among the 

 Elk, the Mule deer, the Columbia deer, or the Acapulco deer.
