A Scottish anatomist examines movement on land, in water and through the air, from the stride of quadrupeds and the stroke of fish to the wings of insects, bats and birds. Pettigrew argues that the wing works by a twisting, figure-of-eight action, and closes with a dissertation on aeronautics and the prospects of human flight.
