"Cheiro" says, “I have noticed that persons possessing this line have a double nature; one side sensitive, and the other side cold and cruel. They also have wonderful powers of construction, their plans are good, their advice excellent, and with a strong thumb it shows them to possess power to win and make a name, and to hold and keep their position.” This definition may, or may not be the correct one, for the double Head line is a rarity and does not afford much opportunity for observing its effect upon individuals as a whole: but from my own ex­perience I am of opinion that it indicates an increase of in­tellectual capacity and good inheritance and fortune.
