Majicman Notes

You must seat yourself in a bony armchair, preferably of Spanish style, with your head tilted back and resting on the stretched leather back. Your two hands must hang beyond the arms of the chair, to which your own must be soldered in a supineness of complete relaxation. […]

In this posture, you must hold a heavy key which you will keep suspended, delicately pressed between the extremities of the thumb and forefinger of your left hand. Under the key you will previously have placed a plate upside down on the floor…. The moment the key drops from your fingers, you may be sure that the noise of its fall on the upside down plate will awaken you, and you may be equally sure that this fugitive moment when you had barely lost consciousness and during which you cannot be assured of having really slept is totally sufficient, in as much as not a second more is needed for your whole physical and psychic being to be revivified by just the necessary amount of repose. For it is exactly, and neither more nor less, what you needed before undertaking your virtuous afternoon labors.
