^† I am most anxious to avoid introducing anatomical subjects, which would be foreign to the pages of the Geologist, but I may take this opportunity of stating my belief based upon constant and careful observation, that the human brain possesses organs—e. g., the “third cerebral lobe,” the “posterior cornn,” and the “hippocampus minor,” which are absent in the brains of the apes. I am aware that several zoologists have lately expressed a contrary opinion, but I cannot refrain from stating tho result of my inquiries, although contrary to the theory of transmutation. Truth should be paramount over any preconceived hypothesis.
