Now as Linneus had no more power to alter a name once 
founded, than has any other person, the original names must stand, 
if not pre-oceupied. In this connection it is a curious thing, that 
despite the vigilance of our American friends, no one has observed, 
so far as I know, the original name of the Dodo. 
In spite of the difficulties, and they are many, I am of the 
opinion that a rigid adherence to the law of priority, would eventually 
lead to a great simplification of nomenclature, but the impossibility 
of determining what an author means when he refers to a genus and 
species founded by an earlier author, allows one to regard with respect 
the views of those who think priority tempered with common sense 
the better method. Briefly, it amounts to this; an author says he 
has a specimen of Mus musculus Linneus: in the first place we ask 
does the author know what Linneeus meant by Mus musculus? in the 
second, is the author competent to judge that he has that identical 
species? The question therefore must always be one of personal 
idiosyneracy, and finality is practically impossible.
