7. the idea of development assumed another form in the speculations of German idealism. Hegel conceived the successive periods of history as corresponding to the ascending phases or ideas in the self-evolution of his Absolute Being. His Lectures on the Philosophy of History were published in 1837 after his death. His philosophy had a considerable effect, direct and indirect, on the treatment of history by historians, and although he was superficial and unscientific himself in dealing with

gradually changing specific differences. Although, as we shall see hereafter, it may frequently or even generally be impossible to specify with exactness the forms of bifurcation in the process of evolution, yet the conception is one of fundamental importance. The ideas involved in this sketch are no doubt somewhat recondite, but I hope to render them clearer to the non-mathematical reader by 1 In order not to complicate unnecessarily this explanation of a general principle I have not stated fully all

a case of an eclipsing binary system, and that the two stars are close together. It is not of course proved that the figures of the stars are ellipsoids, but gravitation must deform them into a pair of elongated bodies, and, on the assumptions that they are not enveloped in an absorptive atmosphere and that they are ellipsoidal, their shapes must be as shown in the figure. This light-curve gives an excellent illustration of what we have reason to believe to be a stage in the evolution of stars

less from the parent (variation). The thus modified offspring, subjected to natural selection, ultimately perish if they are unadapted, but survive if they are adapted to their surroundings. Repetitions of this process finally bring the descendants of plants to differ materially from their ancestors (evolution). The-end of the process seems to be the development of organisms which are little or not at all subject to variation (monotypic genera). All genera of plants containing a large number

of Philadelphia, which in 1860 had elected Darwin to membership, published the first important direct contribution to the subject of evolution made by one not directly under the influence of the Boston academies. This contribution, On the Origin of Genera, was made by Cope, who for several years had been submitting papers to the academy of a descriptive and semi-speculative character, anti largely dealing with the classification of reptiles. I believe that I am perfectly safe in saying that no

force of facts demonstrating that if the process known as evolution operates anywhere, it operates everywhere, and that man can be no element of discord in a universal order which is alike his stimulus and safeguard. In forcing, as it were, Darwin's hand, Huxley rendered him enormous service. He prepared the way for the publication of The Descent of Man, whereby the significant issues of the theory of natural selection were brought home to men's business and bosoms.' Significant, because

waited. It was emphatic. I am prepared, he said, to go to the stake, if requisite, in support of the chapters marshalling the evidence for evolution, and Darwin's delight expressed itself in willingness to sing his Nunc Dimittis. Huxley, master of clear and vigorous English, presented the facts proving the descent of man and the higher mammals from a common ancestry, and, what was of profound significance, the evidence of an unbroken chain of psychical continuity between the lowest and the most

bring when it came division and pain—not peace, but a sword. And now that the battle of evolution had long been over, the dominant feeling, as they looked back upon the past half-century, was of pathos even more than of triumph. In all the boundless realm of philosophy and science there was no thought which had carried with it so much of pain, but in the end not long delayed, so much of the joy which came of intellectual activity and effort, as the doctrine of organic evolution which must always
