5. That the different parts of the brain having been found by long experience to be appropriated to different functions, those parts are and have the same design, and are produced by the same faculties in all human beings. Under one of these heads all phrenological facts must fall. From these principles also, it must be evident that the brain is dependant for its form and character on the developement of the mind in any individual, and in this manner phrenology ascertains the natural bias of the mind, so as to direct education;--it ascertains similarity of pursuits and dispositions so as to improve social intercourse;--it ascertains at any time of life what faculties require to be cultivated or to be checked, what sentiments or passions preponderate in the individual, for good or for evil, what should be repressed, as well as those parts wherein increase should be aimed at, it points out the persons with whom we sympathize, or towards whom we may have an antipathy,--in the treatment of mental disease, its use is obvious. "No more satisfactory proof of this can be referred to, than the extraordinary success of the experiments at the Hanwell Lunatic Asylum under the direction of Dr. and Mrs. Ellis. Regarding the brain not as an entire organized mass, but as an assemblage of organs, some of which may come into a morbid condition while the rest remain comparatively healthy, the course pursued at that excellent institution has been, by kindness and by engaging the attention of the patient, to exercise those organs which are sound, and, by diminishing the action of those which are in a diseased state, to restore them to the healthy performance of their functions. The success which has attended the experiment stands without precedent in the annals of insanity." From this treatment we learn that cures have averaged ninety in a hundred.
