couple of heads which, in the Sportsman's Calendar, are called a brace of knowing ones; and, as a great many people about London affect to be thought knowing ones, they dress themselves in these fashions, as if it could add to the dignity of ahead, to shew they have taken their degrees from students in the stable, up to the masters of arts, upon a coach-box.
