For, I wonder if you have noticed that the movement in every case presents a chain of contrasts and repetitions. Start, for example, with the left foot of _Firmness_, and move your finger over the direction of the figure; first up the calf of the leg to the knee; then off toward the right to the hip; then leftward up the body, then again to the right at the slope of the shoulders; then slightly to the left up the neck, and lastly note the face turned to the right. You will have found that your finger has described a series of zig-zags. If you start with the other foot, the figure will equally present a series of zig-zags, though some differ from the former ones.
