All ladies recognize the law of harmony in colors; and in the selection of a dress or bonnet, they try to secure colors that will harmonize with their complexions. They do not all understand the law sufficiently to always conform to it, as I frequently see ladies in my audience who have blundered in this respect, and who wear articles hideously unbecoming. But they all try, and you cannot inflict a greater punishment upon a woman than to compel her to appear in church, or at a lecture, in a costume in which she knows she has violated this law. But, ladies, just think for a moment, if it is a misfortune to have to wear for a season a dress or bonnet which is not becoming to you, what a calamity it is to be compelled to wear a husband who does not harmonize with you, and that for life. And the worst of it is, they never wear out. Every musician in my audience understands that, in music, if I strike two notes, of the same pitch and quality, I have produced no harmony, I have only intensified the volume of the tone. If I strike a first and third, or a first and fifth, I produce harmony, because the vibrations of those notes, in combination, are such as produce an agreeable sound. If I strike certain other notes, I produce a discord, and the sound is unpleasant. We cannot have harmony without a difference in pitch and quality, but we can have difference in pitch and quality without harmony. To produce perfect music, we must have soprano, alto, tenor and bass to carry all the parts. The tenor and soprano would furnish us a very poor concert, and the alto and bass alone would produce rather monotonous music. But we have studied harmony in music until we have evoked divine results, and our achievements in harmony of colors has beautified the world with transcendent art. In the Science of Humanity there are certain combinations of constitution which, in matrimonial association, are harmonious. There are certain other combinations which are discordant. The union of harmonious natures results in agreeable association, financial success and perfection of offspring. The attempted union of discordant natures results in domestic misery, divorces by wholesale, pauperism, disease and crime, and worst of all, the perpetuation of all these evils in a deformed, diseased and vicious posterity. In stating the law of harmonious selection, the general rule is, that the parties should bear a _complementary_ relation to each other. That is to say, there should be such a combination of temperaments, dispositions and appearances, that any departure from the correct ideal of perfect humanity in the one should be supplied by the development of the other, in order that the two organizations, when added together, should constitute a perfect type of Humanity.
