Thus when the levers are raised, the piston rods draw down the pistons towards the bottom of the cylinder, and the dolphins working on pivots, releasing the valves in the cylinders, fill the cavity of the cylinders with air. Thereupon the piston rods raise the pistons within the cylinders with rapid and violent strokes and close the openings above, with the valves; the air in the cylinders is forced by the pumping into the pipes. Through these it rushes into the air-vessel and by the neck into the chest.
