-
The doctrine of similarity of structure. Thus, the two sides of the body are said to be 'homologous.' Homologous, homomorphous, or homoeomorphous tissues are those that resemble others; in opposition to heterologous, heteroclite, or heteromorphous, which are new formations. Homology seems now to be accepted as the designation of the doctrine or study, the subject of which is the relations of the parts of animal bodies.-Owen.
