blances were to be called
_homoplastic_. "Homoplasy includes all cases of close resemblance of
form which are not traceable to homogeny, all details of agreement not
homogenous, in structures which are broadly homogenous, as well as in
structures having no genetic affinity" (p. 41). Serial homology, for
instance, was a case of homoplasy.

The term "analogy" was to be retained for cases of functional
resemblance, whether homogenetic or not.

The attempt was an interesting one, but most morphologists wisely
adhered to the old concept of homology, in spite of Lankester's
declaration that this belonged to an older "Platonic" philosophy, and
ought to be superseded by a term more consonant with the new philosophy
of evolution.

[369] Haeckel had an intense admiration for Goethe's
morphological work. It is a curious coincidence that the
work of Goethe, Oken and Haeckel was closely associated
with the town of Jena.

[372] The bion is the physiological, as the morphon is the
morphological, individual.

[375] It was hinted at by Tiedemann. "It is clear that,
proceeding from the earlier to the more recent strata, a
gradation in fossil forms can be established from the
simplest organised animals, the polyps, up to the most
complex, the mammals, and that accordingly the animal
kingdom as a whole has its developmental periods just
like the single individual organism. The species and
genera which have become extinct during the evolutionary
process may be compared with
