But two corresponding vertebrae, each from a different animal, are special homologues of one another, and general homologues of the corresponding vertebra of the archetype: Relations of homology are of three kinds: the first is that above defined, viz. the correspondency of a part or organ, determined by its relative position and connections, with a part or organ of a different animal; the determination of which homology indicates t h a t such animals are constructed on a common type: when for example the correspondence of the basilar process of the h u m a n occipital bone with the distinct bone called 'basi-occipital' in a fish or crocodile is shown, the special homology ofthat process is determined.
He does, however, suggest that the influence of Sedgwick, Whewell, a n d Conybeare p e r s u a d e d Owen to establish the archetype as in the mind of the Creator. This contrasts with the view of Desmond (1989), who, a s s u m i n g t h a t O w e n s a r c h e t y p e h a d always c o r r e s p o n d e d to a Platonic idea, saw it as an establishment ploy against radical medical practitioners in London, who were advocates of Lamarckian evolution and of the suspect transcendentalism of Geoffroy Saint-Hilaire (see below).
