If you want to use a magic mirror, don't forget the following roles: 1. The mirror must only be touched by its owner, in order to avoid the mixture of strange magnetism, which can annul that which the mirror was charged for. Other persons may look at it, but they must not touch the frame or the surface of the mirror. 2. If the surface of the mirror is tarnished, one should remove the dirt with soap. Next, one washes it with alcohol and, when the mirror is dry, one polishes it again with some oxygen fluorine, wiping it with a rag of smooth silk or a deerskin. 3. Every day, for five minutes, one magnetizes the mirror with the right hand. 4. Following that, one refines the action of the surface of the mirror by means of magnetic passes made with the left hand. 5. The more often and the longer that one uses a magnetic mirror, the better it is, for the action of the mirror augments its use. 6. To sleep with the aid of the magnetic mirror, it is necessary to fix the attention in the center, calmly and without the least preoccupation of the spirit. Visions will appear, then, while dreaming. 7. It is necessary that the brilliant surface of the mirror should not be struck by the rays of the sun, which paralyze its magical action—when you use the mirror, present its back to the window. 8. The magic mirror must be as clear as a book. 9. If several persons wish to look at the same time, hang the mirror on the wall—and let no person touch it. 10. The best position for vision in the magic mirror is one where no one's reflection is witnessed. You can find this position by inclining the mirror in all ways, until the surface shows a lone sheet of deep water, smooth and limpid. When the magnetism, coming from your eyes, has been accumulated above the mirror (a few millimeters above its surface), the limpid water will be replaced by the desired vision.
