'Yes, sir,' replied the physician, 'I promise success, through God's assistance, and to-morrow I will make trial of it.'
The physician returned to his quarters, and made a mallet, hollow within, and at the handle he put in his drugs. He made also a ball in such a manner as suited his purpose, with which, next morning, he presented himself before the king, and, falling down at his feet, kissed the ground.
