Further investigation by Mr. Lane and Mr. Salt furnished other interesting results. A boy eight or nine years of age was usually chosen at random from those who happened to be passing by. Invocations were written upon paper by the magician, calling upon his familiar spirit, and also a verse from the Koran "to open the boy's eyes in a supernatural manner so as to make his sight pierce into what is to us the invisible world." These were thrown into a brazier with live charcoal and burned with aromatic seeds and drugs. The magic square, that is a square within a square, was drawn in the boy's palm, and certain Arabic characters were written in the spaces between the squares; ink was then poured into the centre, and upon that the boy was to gaze intently. In this way visions were produced and various persons and scenes were described. Finally, Mr. Lane desired that Lord Nelson should be called for. The boy described a man in European clothes of dark blue, who had lost his left arm; but looking closer he added--"No, it is placed to his breast." Lord Nelson had lost his right arm and it was his custom to carry the empty sleeve attached to his breast. Mr. Lane adds, "Without saying that I suspected the boy had made a mistake I asked the magician whether objects appeared in the ink as if actually before the boy's eyes, or as if in a glass, which made the right side appear the left? He replied, 'They appear as in a mirror,' This rendered the boy's description faultless." It is remarkable to notice how prevalent this mode of divination or second-sight has been in all ages. Traces of the same procedure have been found in Egypt, Persia, China, India, Greece, and Rome, and notably in Europe generally, from the tenth to the sixteenth centuries. A lady who withholds her name from the public, but who is perfectly well known to Mr. Myers, of the Society for Psychical Research, and who chooses to be known as Miss X., has been at great pains to collect curious information upon this subject and has added her own very interesting experience in crystal-gazing. She writes, "It is interesting to observe the close resemblance in the various methods of employing the mirror, and in the mystic symbolism which surrounds it, not only in different ages, but in different countries. From the time of the Assyrian monarch represented on the walls of the northwest palace of Nimrod down to the seventeenth century, when Dr. Dee placed his 'Shew Stone' on a cushioned table in the goodly little chapel next his chamber in the college of which he was warden at Manchester, the seer has surrounded himself with the ceremonials of worship, whether to propitiate Pan or Osiris, or to disconcert Ahriman or the Prince of Darkness."
