Plate 10, The Art of Swimming: Floating. “Should the feet seem too heavy, or incline to descend, the hands or fingers must be raised a little out of the water: this will counterbalance the feet, the breast being the center of buoyancy [fig 1]…To remain suspended in the water…the head must be thrown back, and the chin elevates higher than the forehead; the breast must be inflated, the back made quite hollow, and the arms and hands kept under water [fig 2].”
