As it has ever been the custom of man to act as if he were eternal, and lavishly to scatter the limited force which he embodies as though the supply were inexhaustible, it produces no unaccustomed surprise to witness the useless expenditure of force which is so frequently made at the present time. It may even, perhaps, be deemed a token of some modesty, that the being, who since his first formation has been continually occupied in metaphysical regions with the investigation of the origin of all things, should be content for a while to amuse himself with physical theories concerning his own origin. That which is to be regretted in the new and comparatively praiseworthy occupation is the old evil of hasty theorizing on the one hand, and on the other hand, the evil, scarcely less ancient, of an impetuous eagerness to demolish any theory, however plausible, which comes athwart a favourite prejudice. What though the anatomist does discover a very close resemblance and very slight differences between the structure of a gorilla and the structure of a human being; there is no need, on that account, that mankind in a feeling of injured dignity should angrily rouse up and disclaim the undesired relationship. Whatever may be said or written, it is quite plain after all that a man is not a gorilla, and that a gorilla is not a man; it is furthermore manifest that gorillas do not breed men now-a-days, and that we have not the shadow of any evidence to guide us in forming; an opinion as to what they may have clone in times past. The negative testimony of Du Chaillu, who says that he searched in vain in the gorilla region for any intermediate race or link between it and man, scarcely adds anything to the conviction of the non-existence of any such link, which has long been universally entertained.*
