By the term Temperament, is meant the preponderance in development of some element or system of organs in the body, to such an extent as to give to the character a distinctive recognizable type, a temper or disposition resulting from the predominance of some one element in the character which modifies and gives tone to all the rest, resulting from its superior development. As a matter of fact, there are as many different temperaments as there are individuals, no two individuals having the same constitution; but science classifies them under distinctive heads, as their developments are approximately the same, or as their developments are in the same general direction, regardless of exact degrees. ELECTRO-MAGNETIC TEMPERAMENTS. THE ELECTRIC TEMPERAMENT exists when electricity dominates over magnetism in the organization. Its characteristics are Gravity, Receptivity, Darkness, and Coldness. This temperament was formerly called the Bilious or Brunette Temperament. It is distinguished by dark, hard, dry skin, dark, strong hair, dark eyes, olive complexion, and usually by a long, athletic form of body. It is remarkable for concentrativeness of design and affections, strong gravity, drawing power and cohesiveness, strong will, resolution, dignity, serious disposition and expression; moderate circulation and coolness of temperature. It is produced by a dry, hot climate, common in southern latitudes and almost universal in tropical natives. Persons of this temperament are better adapted to hot climates because electricity dominates over magnetism, and they do not antagonize the climate by the radiation of magnetism, but rather thrive on the magnetism which they absorb. This temperament is closely analogous to the condition of tropical animals and birds.
