    upon a hook or nail by the curved part B. The ends D and E will then be presented upwards, the liquid being retained in the siphon by the atmospheric pressure acting on both surfaces at D and E. When the leg B C D is immersed in a vessel of liquid, the surface D is pressed down by the weight of the incumbent liquid, and also by the atmospheric pressure acting above that. This pressure is transmitted to E, where it is resisted by the atmospheric pressure only, consequently the water will' be driven from E with a force equivalent to the hydrostatic pressure on the surface D.
