Absorption, n.

The act or process of imbibing or swallowing; either by water which overwhelms, or by substances, which drink in and retain liquids; as the absorption of a body in a whirlpool, or of water by the earth, or of the humors of the body by dry powders. It is used also to express the swallowing up of substances by the earth in chasms made by earthquakes, and the sinking of large tracts in violent commotions of the earth.
