Take the skeleton of a man, tilt the pelvis, shorter the femur, legs and arms, elongate the feet and hands, fuse the phalanges, elongate the jaws while shortening the frontal bone and, finally, elongate the spine, and the skeleton will cease to represent the remains of a man and will be the skeleton of a horse.
