“ In Irish folk-lore we find the story of one Rickard, surnamed the Rake, from his worthless character. A good-natured, idle fellow, he spent all his evenings in dancing,—an accomplishment in which no one in the village could rival him. One night, in the midst of a lively reel, he fell down in a fit. "He's struck with a fairy-dart," exclaimed all the friends, and they carried him home and nursed him; but his face grew so thin and his manner so morose that by and by all began to suspect that the true Rickard was gone and a changeling put in his place. ”
