Note 401 — Chapter XII · MAGIC, ASTROLOGY, AND ALCHEMY.

Whenever I desired the boy to call for any person to appear, I paid particular attention both to the magician and to ’Osmán. The latter gave no direction either by word or sign; and indeed he was generally unacquainted with the personal appearance of the individual called for. I took care that he had no previous communication with the boys; and have seen the experiment fail when he could have given directions to them, or to the magician. In short, it would be difficult to conceive any precaution which I did not take. It is important to add, that the dialect of the magician was more intelligible to me than to the boy. When I understood him perfectly at once, he was sometimes obliged to vary his words to make the boy comprehend what he said.
