A young man, or it may be an old one, in love or not in love, has obtained possession by a contract duly recorded at the registration office in heaven and on the rolls of the nation, of a young girl with long hair, with black liquid eyes, with small feet, with dainty tapering fingers, with red lips, with teeth of ivory, finely formed, trembling with life, tempting and plump, white as a lily, loaded with the most charming wealth of beauty. Her drooping eyelashes seem like the points of the iron crown; her skin, which is as fresh as the calyx of a white camelia, is streaked with the purple of the red camelia; over her virginal complexion one seems to see the bloom of young fruit and the delicate down of a young peach; the azure veins spread a kindling warmth over this transparent surface; she asks for life and she gives it; she is all joy and love, all tenderness and candor; she loves her husband, or at least believes she loves him. The husband who is in love says in the bottom of his heart: “Those eyes will see no one but me, that mouth will tremble with love for me alone, that gentle hand will lavish the caressing treasures of delight on me alone, that bosom will heave at no voice but mine, that slumbering soul will awake at my will alone; I only will entangle my fingers in those shining tresses; I alone will indulge myself in dreamily caressing that sensitive head. I will make death the guardian of my pillow if only I may ward off from the nuptial couch the stranger who would violate it; that throne of love shall swim in the blood of the rash or of my own. Tranquillity, honor, happiness, the ties of home, the fortune of my children, all are at stake there; I would defend them as a lioness defends her cubs. Woe unto him who shall set foot in my lair!” Well now, courageous athlete, we applaud your intention. Up to the present moment no geographer has ventured to trace the lines of longitude and latitude in the ocean of marriage. Old husbands have been ashamed to point out the sand banks, the reefs, the shallows, the breakers, the monsoons, the coasts and currents which have wrecked their ships, for their shipwrecks brought them shame. There was no pilot, no compass for those pilgrims of marriage. This work is intended to supply the desideratum. Without mentioning grocers and drapers, there are so many people occupied in discovering the secret motives of women, that it is really a work of charity to classify for them, by chapter and verse, all the secret situations of marriage; a good table of contents will enable them to put their finger on each movement of their wives’ heart, as a table of logarithms tells them the product of a given multiplication.
