The first question that occurs to the enlightened enquirer, when he learns that the functions of the brain have been positively determined by experiment, is whether the cranioscopy of Gall and Spurzheim was successful in locating the cerebral functions, and how nearly their inferences from development correspond with the revelations of experiment. It is with great pleasure that I am able to say that the system of Gall and Spurzheim was a wonderful approximation to the truth. Dr. Gall was pre-eminently the scientific pioneer of the nineteenth century. No single individual ever did so much to enlarge the sphere of human knowledge, and to establish the permanent foundations of philosophy. Up to his time, the brain of man was at once the greatest mystery of anatomy and the repository of a greater amount of wisdom and truth than all other realms of science which had previously been explored. But so limited was the knowledge, and so narrow the understanding of the learned, that the grandeur of cerebral science was not even suspected, and, even at the present time, it is so remote from the speculations of the learned that, like a distant star, it has few practical relations to their life; nor will its magnitude be realized until an ample literature shall have made its scientific record.
