The lamp this slave spoke of was the wonderful lamp, which Aladdin had laid upon the shelf before he departed for the chase: this he had done several times before; but neither the princess, the slaves, nor the eunuchs had ever taken notice of it. At all other times except when hunting he carried it about his person.
The princess, who knew not the value of this lamp, and the interest that Aladdin, not to mention herself, had to keep it safe, entered into the pleasantry, and commanded a eunuch to take it and make the exchange. The eunuch obeyed, went out of the hall, and no sooner got to the palace gates than he saw the African magician, called to him, and showing him the old lamp, said: "Give me a new lamp for this?"
