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 symptoms of it either among the 
Elk, the Mule deer, the Columbia deer, or the Acapulco deer.
