These were essentially identical with the centra of the four vertebræ of Oken.
This point, it is interesting to note, had already been made by Oken in his Programm .
These discoveries were confirmed and extended for the 135chick by the embryologist Huschke, a pupil of Oken.
Oken and St Hilaire would have said that it was "all extremity."
Suppose the sceptic takes the ground advocated by Oken and the author of the “Vestiges.”
Oken thought them to be related to the marsupials, or pouched animals.
Oken and Goethe amplified it towards the end of the last, and at the beginning of the present century.
He superadded the evolutionary theories of Oken, which were equally idealistic, but were altogether repugnant to Cuvier.
It was to a certain extent, however, thrown into disrepute by various fantastic theories with which Oken surrounded it.
Oken was spinning in metaphysical Germany his fanciful parodies of the Lamarckian hypothesis.
