sciences, we are entitled to say of it as Schleicher said of Darwin's theory of the origin of species, it depends upon observation, and is essentially an attempt at a history of development. Other questions there are in connection with language and evolution which require investigation—the survival of one amongst several competing words (e.g. why German keeps only as a high poetic word ross, which is identical in origin with the English work-a-day horse, and replaces it by pferd, whose congener the

3. In the first quarter of the nineteenth century the meaning of genetic history was fully realised. Genetic perhaps is as good a word as can be found for the conception which in this century was applied to so many branches of knowledge in the spheres both of nature and of mind. It does not commit us to the doctrine proper of evolution, nor yet to any teleological hypothesis such as is implied in progress. For history it meant that the present condition of the human race is simply and strictly

indications may suffice to show that the new efforts to interpret history which marked the first half of the nineteenth century were governed by conceptions closely related to those which were current in the field of natural science and which resulted in the doctrine of evolution. The genetic principle, progressive development, general laws, the significance of time, the conception of society as an organic aggregate, the metaphysical theory of history as the self-evolution of spirit,—all these ideas

homologous considerations in other fields of thought1, and I shall pass on thence to illustrations which will teach us something of the evolution of stellar systems. States or governments are organised schemes of action amongst groups of men, and they belong to various types to which generic names, such as autocracy, aristocracy or democracy, are somewhat loosely applied. A definite type of government corresponds to one of our types of motion, and while retaining its type it undergoes a slow

, he points out that for a gaseous star the agency which effects the separation will no longer be rotation alone; gravitation also will tend towards separation...From numerical results obtained in the various papers of my own,...I have been led to the conclusion that a gravitational instability of the kind described must be regarded as the primary agent at work in the actual evolution of the universe, Laplace's rotation playing only the secondary part of separating the primary and satellite

forth in his own words the inception in his mind of the problems, geological, zoological and botanical, hypothetical and theoretical, which he set himself to solve and the steps by which he proceeded to investigate them with the view of correlating the phenomena of life with the evolution of living things.

outside the range of ordinary phenomena. A special branch of inquiry, that of Teratology, was devoted to them, but it constituted a science by itself, sometimes connected with morphology, but having scarcely any bearing on the processes of evolution and heredity. Darwin was the first to take a broad survey of the whole range of variations in the animal and vegetable kingdoms. His theory of Natural Selection is based on the fact of variability. In order that this foundation should be as strong

theory of transformation which he had erected on a broad inductive basis; and he had sufficient penetration to detect the agencies that had been at work in the evolution of the erect bimanous man from the arboreal and quadrumanous ape. He had, however, few empirical arguments to advance in support of his hypothesis, and it could not be established until the further development of the biological sciences—the founding of comparative embryology by Baer (1828) and of the cell-theory by Schleiden

, governed by unalterable and eternal laws. In my philosophical book Die Weltr tsel (1899)1 and in the supplementary volume Die Lebenswunder (1904)2, I have endeavoured to show that this pure monism is securely established, and that the admission of the all-powerful rule of the same principle of evolution throughout the universe compels us to formulate a single supreme law—the all-embracing Law of Substance, or the united laws of the constancy of matter and the conservation of energy.

theory. At the present day the whole subject of palaeobotany is a study in evolution, and derives its chief inspiration from the ideas of Darwin and Wallace. In return it contributes something to the verification of their teaching; the recent progress of the subject, in spite of the immense difficulties which still remain, has added fresh force to Darwin's statement that the great leading facts in palaeontology agree admirably with the theory of descent with modification through variation and

XXVI EVOLUTION AND THE SCIENCE OF LANGUAGE BY P. GILES, M.A., LL.D. (Aberdeen), Reader in Comparative Philology in the University of Cambridge. IN no study has the historical method had a more salutary influence than in the Science of Language. Even the earliest records show that the meaning of the names of persons, places, and common objects was then, as it has always been since, a matter of interest to mankind. And in every age the common man has regarded himself as competent without special

No evidence for such ray-less changes in ordinary elements is yet known, perhaps none may ever be obtained; but the possibility should not be forgotten. In the strict sense of the word, the process of atomic disintegration revealed to us by the new science of radio-activity can hardly be called evolution. In each case radio-active change involves the breaking up of a heavier, more complex atom into

characteristic phase in the evolution of opinion regarding the phenomena of the Ice-Age. At first the so-called Drift, also scattered boulders and striated rock-surfaces, were all attributed to powerful debacles produced by earthquake shocks whereby the sea was violently launched across the surface of the land. When the idea gained ground that ice had in some way helped in these operations, the superficial accumulations were still regarded as having been deposited in the sea, over which
