In the classings of natural history, the great- 
est men have frequently fallen into errors ; 
and, perhaps, in the present instance, it would 
be difficult to Rx, with precision, the exadl 
boundaries of the respe^cive species. 
We feel no difficulty, however, in decidedly 
pronouncing, that it is the Brown kind of 
Ring-Tailed Eagle, which we have delineated,
