Note 4 — THE STORY OF THE MERCHANT AND THE GENIE

These tales are furnished throughout with a certain imaginary machinery. They have, as their foundation, the perpetual intervention of certain fantastic beings, in most cases superior to man, but yet subordinate to the authority of certain favored individuals. These beings may, for our purpose, be generally divided into genies, whose interference is generally for evil; peris, whose presence indicates favorable issues to those whom they befriend; and ghouls, monsters which have a less direct control over man's affairs, but represent any monster repugnant or loathsome to mankind.
