" The build of his form depends upon the balance and regularity of his life, and upon the impressions he receives from the world; for in accordance with the attitude he takes towards life, his every thought and action adds or takes away, or removes to another place, the atoms of his body, thus forming the lines and muscles of form and feature. For instance the face of a man speaks his joy, sorrow, pleasure, displeasure, sincerity, insincerity, and all that is developed in him. The muscles of his head tell the phrenologist his condition in life. There is a form in the thought and feelings which produces a beautiful or ugly effect. "
