"Among the remarkable inventions of a remote era, may be mentioned bellows and siphons. The former were used as early as the reign of Thothmes the Third, and contemporary of Moses, being represented in a tomb bearing the name of that Pharaoh. They consisted of a leather bag, sewed and fitted into a frame, from which a long pipe extended for carrying the wind to the fire. They were worked by the feet, the operator standing in front of them, with one under each foot, and pressing them alternately, while he pulled up each exhausted skin by a string." — Goodrich, 1844

A bent tube with limbs of unequal length, used for drawing liquids from one vessel into another.

Siphon

A bent tube with limbs of unequal length, used for drawing liquids from one vessel into another.

"The action of the siphon illustrates the effect of atmospheric pressure. It is simply a bent tube having unequal branches, open at both ends, and is used to convey a liquid from a higher point to a lower, over an intermediate point higher than either." &mdash; Hallock, 1905

"The vertical distance form the level of the upper liquid to the highest point of the tube (ab) is the length of one arm; the vertical distance from the highest point of the tube to the lower end of the tube, or to the level of the liquid into which it dips (cd), is the length of the other arm. The second of these must exceed the first." -Avery 1895

A siphon (also spelled syphon) is a continuous tube that allows liquid to drain from a reservoir through an intermediate point that is higher, or lower, than the reservoir, the flow being driven only by the difference in hydrostatic pressure without any need for pumping. It is necessary that the final end of the tube be lower than the liquid surface in the reservoir

A Siphon can be started by inserting one end of a tube in the liquid and sucking at the other end. It is more convenient to apply suction by means of a side tube as shown to prevent the liquid from entering the mouth.
