In chemistry, the attraction of substances for each other, or the tendency of di imiiar substances to unite with each other. It was formerly applied both to true chemical compounds and to mechanical mixtures forming homogeneous combinations, but is now restricted to the former. 2. In botany and zoülogy, a relationship, founded upon similarity of structure, exist in; tween the members of a species, genus, or other natural division. It is distinguished from analogy, which relates to functional eileen only, and from homology, which has re; merely to similarity in the general plan upon which the related organisms are formed.
