Good Boy

A terrier, known to Professor Owen, was taught to play at hide and seek with his master, who summoned him, by saying ‘Let us have a game;’ upon which the dog immediately hid his eyes between his paws, in the honourable manner, and when the gentleman had placed a sixpence, or a piece of cake in a most improbable place, he started up and invariably found it. His powers were equalled by what was called a fox-terrier, named Fop, who would hide his eyes, and suffer those at play with him to conceal themselves before he looked up. If his play-fellow hid himself behind a window-curtain, Fop would, for a certain time, carefully pass that curtain, and look behind all the others, behind doors, etc., and when he thought he had looked long enough, seize the concealing curtain and drag it aside in triumph.
