Thus, even in a book, human nature was too much for Mr. Day; and yet his Good Boy, Harry Sandford, is something more than the good half of the Fool of Quality. His virtues, although superhuman, are not unlike those of the youthful Thomas Day; but under the guidance of Mr. Barlow, that insufferable model of the Perfect Tutor, he exhibits the mature head of Mr. Day on young shoulders, and so becomes the mouthpiece of Rousseau, the lay-preacher of Mr. Barlow’s sermons, and the chief instrument of the Bad Boy’s reformation.
