The brain is subdivided into two hemispheres, the right and left, by the falciform process of the dura mater, a membrane which dips down one to two inches into the brain, and runs from the root of the nose over to the nape of the neck. This arrangement renders all the phrenological organs DOUBLE. Thus, as there are two eyes, ears, etc., that when one is diseased, the other can carry forward the functions, so there are two lobes to each phrenological organ, one on each side. The brain is divided thus: the feelings occupy that portion commonly covered by the hair, while the forehead is occupied by the intellectual organs. These greater divisions are subdivided into the animal brain, located between and around the ears; the aspiring faculties, which occupy the crown of the head; the moral and religious sentiments, which occupy the top; the physico-perceptives, located over the eyes; and the reflectives, in the upper portion of the forehead. The predominance of these respective groups produces both particular shapes, and corresponding traits of character. Thus, when the head projects far back behind the ears, hanging over and downward in the occipital region, it indicates very strong domestic ties and social affections, a love of home, its relations and endearments, and a corresponding high capacity of being happy in the family, and of making the family happy. Very wide and round heads, on the contrary, indicate strong animal and selfish propensities, while thin, narrow heads, indicate a corresponding want of selfishness and animality. A head projecting far up at the crown, indicates an aspiring, self-elevating disposition, proudness of character, and a desire to be and to do something great; while the flattened crown indicates a want of ambition, energy, and aspiration. A head high, long, and wide upon the top, but narrow between the ears, indicates Causality, moral virtue, much practical goodness, and a corresponding elevation of character; while a low or narrow top head indicates a corresponding deficiency of these humane and religious susceptibilities. A head wide at the upper part of the temples, indicates a corresponding desire for personal perfection, together with a love of the beautiful and refined, while narrowness in this region evinces a want of taste, with much coarseness of feeling. Fullness over the eyes indicates excellent practical judgment of matters and things appertaining to property, science, and nature in general; while narrow, straight eyebrows, indicate poor practical judgment of matter, its quality, relations, and uses. Fullness from the root of the nose upward, indicates great practical talent, love of knowledge, desire to see, and ability to do to advantage, together with sprightliness of mind; while a hollow in the middle of the forehead indicates want of memory and inability to show off to advantage. A bold, high forehead, indicates strong reasoning
