That a young crow is black when it quits the nest is no reason why a young oriole in its first feather plumage should resemble either of its parents simply for the reason that the Corvidae and the Icteridae are related families. In my time, I have known, however, anatomists, or those who considered themselves to be anatomists to jump at conclusions in their own special fields of labor quite as hazardous as this. What has been said in the last paragraph or two, brings me directly up to the next rjoint to be considered, and that is this--our work throughout must be made comparative to be of value or to fulfill its greatest use and higherf purpose--namely, to meet the ends of taxonomy, classification. Series of facts, or even single facts, must be compared and intercompared, and contrasted, within the limits of known affinities and within the range of more or less near relatioushius. A structure by structure comparison, during the various stages of its growth, in the case of the skull of a humming bird and that of a grebe would furnish us with a kind of knowledge that, taxonomically speaking, would be of but little service to us, but if we compare all that we know of the developmental anatomy of the skull of a grebe, with that of a loon, structure by structure, and change by change, and all this knowledge with the corresponding information as derived from our researches upon the skulls of young representatives of the Alcae, and their known allies, then the real needs of classification are met, and the safe substantial progress of this most important department of the science of ornitho...
