Defn: Having the same relative proportion or value, as the two antecedents or the two consequents of a proportion. (c) (Chem.) Characterized by homology; belonging to the same type or series; corresponding in composition and properties. See Homology,
3. (d) (Biol.) Being of the same typical structure; having like relations to a fundamental type to structure; as, those bones in the hand of man and the fore foot of a horse are homologous that correspond in their structural relations, that is, in thier relations to the type structure of the fore limb in vertebrates. Homologous stimulus. (Physiol.) See under Stimulus.
HOMOLOGRAPHIC Hom`o*lo*graph"ic, a. Etym: [Homo- + Gr. graph + -ic; but cf. F. homalographique, Gr.
Defn: Preserving the mutual relations of parts, especially as to size and form; maintaining relative proportion. Homolographic projection, a method of constructing geographical charts or maps, so that the surfaces, as delineated on a plane, have the same relative size as the real surfaces; that is, so that the relative actual areas of the different countries are accurately represented by the corresponding portions of the map.
HOMOLOGUE
Hom"o*logue, n. Etym: [Cf. F. homologue. See Homologous.]
Defn: That which is homologous to something else; as, the corresponding sides, etc., of similar polygons are the homologues of each other; the members or terms of an homologous series in chemistry are the homologues of each other; one of the bones in the hand of man is the homologue of that in the paddle of a whale.
HOMOLOGY
Ho*mol"o*gy, n. Etym: [Gr. Homologous.]
1. The quality of being homologous; correspondence; relation; as, the homologyof similar polygons.
2. (Biol.)
Defn: Correspondence or relation in type of structure in contradistinction to similarity of function; as, the relation in structure between the leg and arm of a man; or that between the arm of a man, the fore leg of a horse, the wing of a bird, and the fin of a fish, all these organs being modifications of one type of structure.
