A dense fog obscured all minds, and the dazzling truth could not pierce it; thus all progress in embryology was precluded. Fifty years had passed, and Wolff, poor and persecuted, had died at Petrograd, an exile from his native land, when Pander and Ernest von Baer grappled anew with the theory of "blastodermic foliation."
I therefore turned my attention to the special study of embryology, as I fortunately possessed sufficient private means to enable me by careful living to dispense with the usual proceeds of my profession.
The three pairs of jaws, modified legs, in the rear half of the head show that this portion is composed of three segments. For only one pair of legs is ever developed on a single segment. Embryology has shown that the portion of the head in front of the mouth is also composed of three segments.
But I have a taste for the homologies, I want to go deeply into the subject of embryology, I want to analyze the protonihilates precipitated from pigeon's milk by the action of the lunar spectrum, shall I not follow my star, shall I not obey my instinct, shall I not give myself to the lofty pursuits of science for its own sake? Certainly you may, if you like.
Traditions represent the ideas, the needs, and the sentiments of the past. They are the synthesis of the race, and weigh upon us with immense force. The biological sciences have been transformed since embryology has shown the immense influence of the past on the evolution of living beings; and the historical sciences will not undergo a less change when this conception has become more widespread.
And when we go below the lowest vertebrates and compare their embryology with that of their invertebrate relatives, we can follow the genealogical tree of our animal ancestors much farther, down to the very lowest groups of animals.
Let us suppose that species are proved, by inference or by experiment, to have arisen by a discontinuous process, of which to-day we have no idea. Would the doctrine be affected in so far as it has a special interest or importance for us? Classification would probably remain, in its broad lines. The actual data of embryology would also remain.
But although the teachings of embryology have failed to realize the great hopes that were placed upon them, their assistance in the formulation of this history of the machine has been of extreme value. Many a bit of obscurity has been cleared up when the embryology of puzzling animals has been studied.
My studies had temporarily led me into a by-path, and apprehending that a great international struggle was imminent, I had turned my investigations in a new direction. My great work, whose publication would have shattered so many scientific idols, was complete. The life history of Nahémah had crowned my inquiries into the embryology, physiology and psychology of psycho-hybrids.
For its theory, still less advanced, the term Eupsychic may complete our proposed nomenclature. Thus then our conception of the opening future may be increasingly defined, since all these apparently predicted phases are already incipient among us, and are thus really matters of observed fact, of social embryology let us say; in short, of city development.
