It is made by forming a spiral tube within, or by winding a flexible tube spirally about, a cylinder. When the cylinder is placed in an inclined position, and the lower end is immersed in water, its revolution will cause the water to move upward through the spiral chambers. Whatever quantity of water first enters the screw immediately descends by its own weight to the lowest point of the spiral; but this point being always shifted higher up by the revolution of the screw, the water may thus be raised to a considerable height. Also called water- screw and spiral —Arch i me dean solid, of the thirteen solids described by Arch i me des, which, without being regular, have all their solid angles alike, all their faces regular, and not le than four faces of any one kind: sometimes incorrectly called semi - regular solids.
