Ludovico had his palace at one end of the town of Milan; at the other was that of the Countess of Pernetti. At midnight, on a certain occasion, Ludovico resolved, at the peril of his life, to make a rash expedition for the sake of gazing for one second on the face he adored, and accordingly appeared as if by magic in the palace of his well-beloved. He reached the nuptial chamber. Elisa Pernetti, whose heart most probably shared the desire of her lover, heard the sound of his footsteps and divined his intention. She saw through the walls of her chamber a countenance glowing with love. She rose from her marriage bed, light as a shadow she glided to the threshold of her door, with a look she embraced him, she seized his hand, she made a sign to him, she drew him in. "But he will kill you!" said he. "Perhaps so." But all this amounts to nothing. Let us grant that most husbands sleep lightly. Let us grant that they sleep without snoring, and that they always discern the degree of latitude at which their wives are to be found. Moreover, all the reasons which we have given why twin beds should be condemned, let us consider but dust in the balance. But, after all, a final consideration would make us also proscribe the use of beds ranged within the limits of the same alcove. To a man placed in the position of a husband, there are circumstances which have led us to consider the nuptial couch as an actual means of defence. For it is only in bed that a man can tell whether his wife's love is increasing or decreasing. It is the conjugal barometer. Now to sleep in twin beds is to wish for ignorance. You will understand, when we come to treat of _civil war_ (See Part Third) of what extreme usefulness a bed is and how many secrets a wife reveals in bed, without knowing it. Do not therefore allow yourself to be led astray by the specious good nature of such an institution as that of twin beds. It is the silliest, the most treacherous, the most dangerous in the world. Shame and anathema to him who conceived it! But in proportion as this method is pernicious in the case of young married people, it is salutary and advantageous for those who have reached the twentieth year of married life. Husband and wife can then most conveniently indulge their duets of snoring. It will, moreover, be more convenient for their various maladies, whether rheumatism, obstinate gout, or even the taking of a pinch of snuff; and the cough or the snore will not in any respect prove a greater hindrance than it is found to be in any other arrangement. We have not thought it necessary to mention the exceptional cases which authorize a husband to resort to twin beds. However, the opinion of Bonaparte was that when once there had taken place an interchange of life and breath (such are his words), nothing, not even sickness, should separate married people. This point is so delicate that it is not possible here to treat it methodically.
