The work before us, again, may be said to be an exposition of the Generelle Morphologie for an educated public, consisting, as it does, of the substance of a series of lectures delivered before a mixed audience at Jena, in the session 1867-8.

The minimum capacity which I have assumed above, however, is based upon the valuable tables published by Professor R. Wagner in his "Vorstudien zu einer wissenschaftlichen Morphologie und Physiologie des menschlichen Gehirns."

Thus a male foetus showing reptilian characters in sexual ducts was exhibited by Shattock at the Pathological Society of London, February 19, 1895. J. Kohlbrugge, "Die Umgestaltung des Uterus der Affen nach den Geburt," Zeitschrift für Morphologie, bd. iv, p. 1, 1901. The nerve endings in the genital region are the same as elsewhere.

The average type of the Theory of Descent of the older or orthodox school, which still lingers in the background with its Darwinism unshaken, is that set forth by Haeckel, scientifically in hisGenerelle Morphologie der Organismen” , andSystematische Phylogenie” , and popularly in hisNatural History of CreationandRiddles of the Universe,” with their many editions.

I know of no more solid and important contributions to biology in the past seven years than Haeckel's work on the Radiolaria, and the researches of his distinguished colleague Gegenbaur, in vertebrate anatomy; while in Haeckel's Generelle Morphologie there is all the force, suggestiveness, and, what I may term the systematizing power, of Oken, without his extravagance.

Professor Haeckel in his "Generelle Morphologie" and in another works, has recently brought his great knowledge and abilities to bear on what he calls phylogeny, or the lines of descent of all organic beings.

The "Generelle Morphologie" is, in fact, an attempt to put the Doctrine of Evolution, so far as it applies to the living world, into a logical form; and to work out its practical applications to their final results.

It must be remembered that all this time Goethe is pursuing his studies of Physical Science. His little book called "Morphologie," published in 1788, immediately after his return from Italy, is a simple, unaffected, practical, statement of the law of growth of plants, which, though suggested before, had quite escaped the attention of the botanists of repute.
