Nature has not left us in the dark with reference to this question. She surrounds us with every incentive to obey her laws, rewards her obedient children with every pleasure the senses can afford, and punishes the disobedient with pains and penalties too numerous and severe to catalogue. Observation is all that is necessary to teach us the law of harmony. We know that the bright red of the rose is heightened in effect by the dark green of the leaf behind it. We observe that chords in music are agreeable to the ear. And we have only to use the same observation, in respect to matrimony, to distinguish certain combinations that produce all that is rich and grand and beautiful in domestic life, and to know others in which the effect is altogether wrong. Society has long since learned the distinction between the Brunette and Blonde the Electric and the Magnetic Temperaments. And the fact is also known that it is natural for those of light complexion to admire those of dark, and _vice versa_. The novelist and the actor recognize this principle, and if the story is well told, and the drama well made up, the hero and the heroine are made to conform to these complexions. The society belle who gives a party, if she be a blonde, invites some dark-eyed lady friend as a foil to her beauty; and the dark-complexioned friend responds cheerfully to the invitation, conscious that her own beauty will be heightened by the contrast. The blonde and brunette are complementary to each other, as far as the temperament is concerned. The Magnetic Temperament is distinguished for its rich arterial circulation and versatility of character, which is deficient in the Electric. The Electric on the other hand, is noted for its strength of bone and muscle and concentrativeness of character, traits deficient in the Magnetic. United, the combination possesses the warmth and versatility of the Blonde with the endurance and power of the Brunette. In the union of the Blonde and Brunette, the law of color is also conformed to, and both appear better than either would apart, or than either would, combined with a person of the same temperament. To illustrate this principle more completely, I will give a few examples.
