"A mountain and spring, showing how the principle of the syphon operates to produce the effect described. Suppose there is a crevice, or hollow in the rock from a to b, and a narrow fissure leading from it, in the form of the syphon, b c. The water from the rill fe, filling the hollow, up to the line a d, it will then discharge itself through the syphon, and continue to run until the water is exhausted down to the l g of the syphon b, when it will cease. Then the water from the rills continuing to run until the hollow is again filled up to the same line, the syphon again begins to act, and again discharges the contents of the reservoir as before, and thus the spring p, at one moment flows with great violence and the next moment ceases entirely." —Comstock, 1850

Water flows frow the higher glass through the tub and into the lower glass.

Siphon

Water flows frow the higher glass through the tub and into the lower glass.

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

"Take a tube bent like the letter U, and, having filled it with water, place a finger on each end, and in this state plunge one of the ends into a vessel of water, so that the end in the water shall be a little the highest then remove the fingers and the liquid will flow out, and continue to do so until the vessel is exhasted." -Comstock 1850
