A remarkable series of tests in the art of scrying, given in the presence of Lane, the great Arabic scholar, and translator of the Arabian Nights, illustrates the fallibility of most of the evidence adduced in such matters, for, at first, Lane was strongly impressed by the exhibition. Although no crystal was used, the process of scrying was precisely the same as in crystal-gazing,—that is to say, the vision called for by the visitors was seen by the scryer on a polished surface. The master of ceremonies was an Arab magician, though, of course, he did not do the scrying himself, but employed a boy for this purpose, for it is generally thought that half-grown boys or girls are more receptive. Although Lane himself was perfectly familiar with Arabic, an interpreter was always present in the interest of the other Europeans who assisted at the experiments. After invoking many mysterious geniuses and burning incense and scraps of paper inscribed with magic formulas, the magician drew a magic square on a large sheet of paper and dropped a quantity of ink in the centre. On this the boy was directed to fix his gaze, and after he had shown that he was thoroughly under the magician’s influence, by describing the images suggested to him, the visitors were permitted to ask him questions. The answers were successful in most cases; a single instance will suffice. When the boy was asked to describe Admiral Nelson, he replied: “I see a man clothed in a dark garb; there is something strange about him, he has but one arm.” Then, quickly correcting himself, he added: “No, I was mistaken, he has one of his arms across his breast.” This correction impressed those present more than the first statement, for it was well known that Nelson usually had the empty sleeve of his coat pinned to his breast. It also seemed as though there could be no collusion, for both the magician and the boy were ignorant of everything English and evidently knew nothing of Nelson. Unfortunately, however, for those who would fain believe that there is something supernatural in scrying, it was later discovered that the interpreter was a renegade Scotchman, masquerading as an Arab, and there can be little doubt that he managed to suggest the boy’s answer. The fact that no satisfactory results were obtained when this interpreter was absent, makes this explanation almost certainly the correct one.
