No one would hesitate to describe the pouter and the tumbler as distinct species, if they were found fossil, or if their skins and skeletons were imported, as those of exotic wild birds commonly are and without doubt, if considered alone, they are good and distinct morphological species.
Concerning their external characteristics we know much; and our classifications, if not satisfactory to all, are at least eminently useful. But when one turns to the morphological sciences of anatomy, histology, embryology, and pathology, one discovers great gaps, where knowledge might reasonably be expected.
This is a gastropod, a lot like Odostomia, but it has parasitical morphological changes so profound that " "There's something else I remember," Brion said, interrupting her enthusiastic lecture, only half of which he could understand. "Didn't Ihjel also hope that you would give some study to the natives as well as their environment? The problem is with the Disans not with the local wild life."
The principal adaptive characters are: both eyes and the pigmentation on the side which is uppermost in the natural position, lower side without eyes and colourless; dorsal and ventral fins continuous and extending nearly the whole length of the dorsal and ventral edges; dorsal fin extending forwards on the head, not along the morphological median line, which is between the eyes, but between the more dorsal eye and the lower side of the body, in the same horizontal plane as the posterior part of the same fin.
In all life-manifestations, this "force from without," must be a pre-existing vital principle operating to effect the otherwise impossible change in matter. : A favorite set-phrase of Professor Bastian in speaking of morphological cells or "units," as he sometimes calls them.
So again, in formerly discussing certain morphological characters which are not functionally important, we have seen that they are often of the highest service in classification.
Morphological study of the child, whose body is transformed in successive ages, should be the basis for the organization of gymnastic exercises, and not emulation. That which has its origin in the body, as constitution or disease, should be considered in the body. No miracle can be performed by the sentiment of emulation.
The belief, at, one time commonly held, that in morphological development and physical appearance the Bantu stand nearer in the scale of evolution to our common ape-like ancestors than do the white people does not seem to be warranted by facts.
If we consider, in fact, that by far the largest proportion of recorded existing species are known only by the study of their skins, or bones, or other lifeless exuvia; that we are acquainted with none, or next to none, of their physiological peculiarities, beyond those which can be deduced from their structure, or are open to cursory observation; and that we cannot hope to learn more of any of those extinct forms of life which now constitute no inconsiderable proportion of the known Flora and Fauna of the world: it is obvious that the definitions of these species can be only of a purely structural, or morphological, character.
It is this vital unit that assimilates or aggregates protoplasmic matter into the morphological cell, or the initial organism in a vital structure, or an approach towards structural form. Morphological cells are not therefore "units," considered as the least of any given whole, nor are they mere structureless matter, or any more homogeneous in character than in substance.
