The colleges were at first little more than schools. The scholars boarded with the professors: there were no funds for the erection of separate buildings. But soon we see the evidences of a persistent effort to make each college an embryonic Oxford or Cambridge. Harvard, Yale and Princeton before completing the first half century of existence were committed to the dormitory system.

If, then, similarity of action is rather hindered than promoted by memory, why introduce it into such cases as the repetition of the embryonic processes by successive generations? The embryos of a well-fixed breed, such as the goose, are almost as much alike as water is to water, and by consequence one goose comes to be almost as like another as water to water.

"Darling," he said, "our children will need no embryonic alterations. They will be born as we are, able to live under Martian conditions. And never again will either of us ever have to wear a marsuit!" He felt the questing touch of Cheng's mind. Cheng: Are you there, Dark? Dark: Here. Cheng: Are you all right? Dark: We're both fine! We're coming out.

The previous chapters have taught us how the human body as a whole develops from the first simple rudiment, a single layer of cells. The whole human race owes its origin, like the individual man, to a simple cell. The unicellular stem-form of the race is reproduced daily in the unicellular embryonic stage of the individual.

In these three classes alone we find the remarkable embryonic membrane, already mentioned, which we called the amnion; a cenogenetic adaptation that we may regard as a result of the sinking of the growing embryo into the yelk-sac. If the evidence of comparative anatomy and ontogeny is ever entirely beyond suspicion, it is certainly the case here.

It is also, I believe, a universal rule, that a rudimentary part is of greater size in the embryo relatively to the adjoining parts, than in the adult; so that the organ at this early age is less rudimentary, or even cannot be said to be in any degree rudimentary. Hence rudimentary organs in the adult are often said to have retained their embryonic condition.

But there can be no doubt that embryonic, excluding larval characters, are of the highest value for classification, not only with animals but with plants. Thus the main divisions of flowering plants are founded on differences in the embryo on the number and position of the cotyledons, and on the mode of development of the plumule and radicle.

He observed that the oldest fishes present many characters which recall the embryonic conditions of existing fishes; and that, not only among fishes, but in several groups of the invertebrata which have a long palaeontological history, the latest forms are more modified, more specialised, than the earlier.

If paragraphs and pages are missing from the brief embryonic recapitulation, whole chapters and volumes of the fossil series have been lost for all time. The investigators whose task it has been to decipher the story of the earth's evolution have had to meet numerous and exasperating difficulties which do not confront the embryologist and anatomist who study living materials.

Immermann first thought of writing a new Münchhausen in 1821, the year of his satirical comedy, The Princes of Syracuse, which contains the embryonic idea of this "history in arabesques."
