Although these several objections seemed to me to have no weight, yet I resolved to make more observations of the same kind as those published, and to attack the problem on another side; namely, to weigh all the castings thrown up within a given time in a measured space, instead of ascertaining the rate at which objects left on the surface were buried by worms. But some of my observations have been rendered

of the 'International Scientific Series' to bring out the second division of the work as a separate treatise, under the title 'Mental Evolution.' This treatise I hope to get ready for press within a year or two. My object in the work as a whole is twofold. First, I have thought it desirable that there should be something resembling a text-book of the facts of Comparative Psychology, to which men of science, and also metaphysicians, may turn whenever they may have occasion to acquaint themselves

be found in any part of the kingdom of nature. It is, also, an interesting fact that intermediate states between organs fitted for widely different functions, may be observed on the same individual plant of Corydalis claviculata and the common vine; and these cases illustrate in a striking manner the principle of the gradual evolution of species. * An English translation of the 'Lehrbuch der Botanik' by Professor Sachs, has recently (1875), appeared under the title of 'Text-Book of Botany,' and

If we admit the principle of gradual evolution, there must formerly have existed many species which presented every successive step between the wonderfully elongated tail-coverts of the peacock and the short tail-coverts of all ordinary birds; and again between the magnificent ocelli of the former, and the simpler ocelli or mere coloured spots on other birds; and so with all the other characters of the peacock. Let us look to the allied Gallinaceæ for any still-existing gradations. The species

proclaim—that this century will be named after him as the Age of Darwinism. That the doctrine of Evolution must prove in the main a true and enduring one it doubted to-day by few really competent minds. We should be the last to say this with rejoicing, if it diminished the sublimity of Creation, or degraded man. But those who have felt pain on fear at the prevailing spread of DARWIN'S views forget that LEIBNITZ was similarly led to declare Newton's law of gravity irreligious; nor have they

, fully twenty-two years ago. He raised evolution from a subordinate to a commanding position in scientific thought. And it was not merely in zoology and in botany that the fresh, powerful impulse was felt; it affected every realm of investigation. It set thinkers in theology, in philosophy, in morals, and in history to reconsider their views, and many of them do not hesitate to tell us that in the evolutionary doctrine they find the safest guide in the subtlest mazes of these interesting

much more successful and reliable as a faithful recorder of what he sees, than as a speculator upon what he does not see. The work before us is a printed and legitimate evolution of close attention to facts of natural history and of healthy neglect of unnatural fancies. And if Mr. Darwin has been able to discover no more than the intelligence of the worm, he has helped many to a broader and brighter view of the intelligence above the worm, evincing itself in the wisdom of its structure, and the

Whether his now well-known theory of evolution will meet the fate of others which have preceded it, or become more enduring amongst scientific doctrines than the views of Lamarck and the author of 'The Vestiges of Creation,' it is of course impossible to say; but the impetus which his various works have given to modern thought and research, and the extraordinary number of biological facts which have been collected and

expression of the plan according to which the succession of Animal and Vegetable forms had been created; not as indicating any genetic continuity between the earlier and the later. The doctrine of Evolution by genetic continuity was advocated (under the designation of 'Creation by Law') in a remarkable book published in 1844, entitled, 'Vestiges of the Natural History of Creation.'

not a doubt that, for the present generation at all events, no subject of scientific inquiry can present a higher degree of interest; and therefore it is mainly with the view of furthering this inquiry that I have undertaken this work. It will thus be apparent that the present volume, while complete in itself as a statement of the facts of Comparative Psychology, has for its more ultimate purpose the laying of a firm foundation for my future treatise on Mental Evolution.

pièces, des espèces, it is manifest that at least a large number of naturalists must admit that species are the modified descendants of other species; and this especially holds good with the younger and rising naturalists. The greater number accept the agency of natural selection; though some urge, whether with justice the future must decide, that I have greatly overrated its importance. Of the older and honoured chiefs in natural science, many unfortunately are still opposed to evolution in every

science, as formerly in the case of Geology, and more recently in that of the principle of evolution. When men like Sir John Herschel or Sir Charles Lyell have spoken of the effects of slowly-acting causes in modifying continents and seas, they have been ridiculed by the thoughtless, who cannot see how the downfall of rain, the slow movement of rivers, the play of waves on shore-lines, can produce such results. In like manner the Biologist is ridiculed who, noting small changes in various races

one of the most vivid aspirations, and, 1 do not hesitate to say, one of the noblest desires of the human mind; it is because it seemed to explain the world of organized beings, just as mathematics, astronomy, geology, and physics have explained the world of inorganic bodies. What Darwin attempted was to refer to the action of second causes alone the marvellous group of phenomena studied by the botanists and the zoologists; he endeavoured to explain their genesis and evolution, just as the

He was married 1831 to his cousin, Miss Emma Wedgwood, by whom he had a large family. After publishing numerous papers and volumes on zoology, geology, and other scientific subjects, Mr. Darwin produced in 1859 his celebrated work on evolution, the Origin of the Species by Means of Natural Selection, which has since been translated into various European languages, and has
