SAT-U-RA'TION, n.

In a general sense, a filling or supply to fullness. In chimistry, the union, combination or impregnation of one body with another by natural attraction or affinity, till the receiving body can contain no more; or solution continued till the solvent can contain no more. The saturation of an alkali by an acid, is by one sort of affinity; the saturation of water by salt, is by another sort of affinity, called solution.
