BLACK-CAPT TITMOUSE. 
403 
off the top of a very tall tree, I found it to be the Black-headed 
Titmouse, with a long and deep indentation in the cranium, the 
scull having been evidently at some former time drove in, and 
fractured, but was now perfectly healed. Whether or not the 
change of voice could be owing to this circumstance I cannot 
pretend to decide.
