Arched foreheads appear properly to be feminine. A forehead neither too perpendicular nor too retreating, but a happy mean, indicates the post-perfect character of wisdom. I might also state it as an axiom that straight lines considered as such, and curves considered as such, are related as power and weakness, obstinacy and flexibility, understanding and sensation. I have seen no man with sharp, projecting eyebones who was not inclined to vigorous thinking and wise planning. Yet, even lacking sharpness, a head may be excellent if the forehead sink like a perpendicular wall upon horizontal eyebrows, and be greatly rounded towards the temples. Perpendicular foreheads, projecting so as not to rest immediately upon the nose, and small, wrinkled, short, and shining, indicate little imagination, little understanding, little sensation. Foreheads with many angular, knotty protuberances denote perseverance and much vigorous, firm, harsh, oppressive, ardent activity. It is a sure sign of a clear, sound understanding and a good temperament when the profile of the forehead has two proportionate arches, the lower of which projects. Eyebones with well-marked, firm arches I never saw but in noble and great men. Square foreheads with extensive temples and firm eyebones show circumspection and steadiness of character. Perpendicular wrinkles, if natural, denote application and power. Horizontal wrinkles and those broken in the middle or at the extremities generally denote negligence or want of power. Perpendicular, deep indentings in the forehead between the eyebrows, I never met save in men of sound understanding and free and noble minds, unless there were some positively contradictory feature. A blue frontal vein, in the form of a Y, when in an open, smooth, well-arched forehead, I have only found in men of extraordinary talents and of ardent and generous character. The following are the traits of a perfectly beautiful, intelligent, and noble forehead. In length it must equal the nose, or the under part of the face. In breadth it must be either oval at the top-like the foreheads of most of the great men of England--or nearly square. It must be free from unevenness and wrinkles, yet be able to wrinkle when deep in thought, afflicted by pain, or moved by indignation. It must retreat above and project beneath. The eyebones must be simple, horizontal, and, if seen from above, must present a simple curve. There should be a small cavity in the centre, from above to below, and traversing the forehead so as to separate it into four divisions perceptible in a clear descending light. The skin must be more clear on the forehead than in other parts of the countenance. Foreheads short, wrinkled, and knotty, are incapable of durable friendship. Be not discouraged though a friend, an enemy, a child, or a brother transgress, for so long as he have a good, well-proportioned, open forehead there is still hope of improvement.
