Even if the apartment is not arranged according to the principles prescribed in the Meditation, you will easily discern the place into which the celibate has vanished, although he be not, like Lord Byron"s Don Juan, bundled up under the cushion of a divan. If by chance your apartment is in disorder, you ought to have sufficient discernment to know that there is only one place in which a man could bestow himself. Finally, if by some devilish inspiration he has made himself so small that he has squeezed into some unimaginable lurking-place (for we may expect anything from a celibate), well, either your wife cannot help casting a glance towards this mysterious spot, or she will pretend to look in an exactly opposite direction, and then nothing is easier for a husband than to set a mouse-trap for his wife.
