Aladdin's intelligence

He changed clothes with the first person he met in the town, and having bought a certain powder returned to the Princess, who let him in by a little side door.Put on your most beautiful dress,he said to her, and receive the magician with smiles, leading him to believe that you have forgotten me. Invite him to sup with you, and say you wish to taste the wine of his country. He will go for some, and while he is gone I will tell you what to do.
