quelques cas frappants chez les saules hybrides. Il est bon de rappeler ici que, dans les cas de parthénogenèse, les embryons des œufs de vers à soie qui n'ont pas été fécondés périssent après avoir, comme les embryons résultant d'un croisement entre deux espèces distinctes, parcouru les premières phases de leur évolution. Tant que j'ignorais ces faits, je n'étais pas disposé à croire à la fréquence de la mort précoce des embryons hybrides ; car ceux-ci, une fois nés, font généralement preuve de

. His advocacy of the doctrine of Evolution in his Monograph of the Radiolaria (1862), first brought it before the attention of German men of Science; his enthusiastic and gallant advocacy ever since has chiefly contributed to its success in that country. Mr. Darwin, in 1873, wrote to Prof. Haeckel, You will do a wonderful amount of good in spreading the doctrine of Evolution, supporting it as you do, by so many original observations. A brilliant writer and investigator, author of a number of

evolution than is yet realised. Your conception of homoplastic modification, leading to similar organisation in distinct lines of descent, has proved no less fertile, and the importance which you have attached to the study of Bionomics, to use your own term, anticipated the great development which the investigation of the conditions of life has since shown, under Prof. Warming's name of Ecology. Your more popular works have spread the knowledge of Evolution beyond the limits of scientific circles; my

doctrine of evolution as expounded by Lamarck and by Robert Chambers. They had (he pointed out) failed to discover any mechanical conditions from the operation of which organic evolution must ensue. But the Darwin-Wallace principle of survival of the fittest in the struggle for existence satisfied Huxley's requirement. He became the convinced advocate of the new doctrine, though I think it is true that he clung to a little heresy of his own as to the occurrence of evolution by saltatory

the study of nature, the theory of evolution extended its enlivening influence to the dominions of all human sciences. For this theory has not only effected a new development of the natural sciences, but it has given better and truer methods of research to other sciences as well, and thus invigorated them to a new and better life. As by the great genius of Darwin and Wallace evolution has proved to be not only a doctrine but a fact even if different opinions may be held about its ways and means

At 10.15. Dr. A. SMITH WOODWARD, F.R.S., V.P.L.S. THE EVOLUTION OF MAMMALS IN SOUTH AMERICA. THE subject of the Evolution of South American Mammals is appropriate on the present occasion, because Darwin was one of the pioneers in the discovery of fossil mammalian remains in the Argentine pampas. During the 'Beagle' expedition he found the first evidence of the extinct ground-sloths, Mylodon and Scelidotherium, and of the strange large hoofed-animal Toxodon. Since Darwin's time, our knowledge

Mendelian lines. It was you, Dr. Galton, who first showed the way by which exact measurement could be applied to the problems of evolution and heredity, and indicated that their laws must be susceptible of proof. You have pointed out a new method, and the possibility of a more logical treatment of evolutionary questions. By establishing such principles as that of Recession to Mediocrity you have added new laws to evolution, and under the name of Cessation of Selection you have suggested an

complement of the principle of evolution in organic life which came to light at about the same time (p. lxxv). It is certainly a striking circumstance that almost simultaneously the study of inanimate and animate nature should have been revolutionised by the discovery of a new controlling principle in each. In another passage Professor Larmor points out that between them there is something in common; the automatic evolution towards improved adaptation, in this case with no limit or equilibrium

In looking at the theory of Evolution, we have to ask not is it desirable, but is it true. But if Evolution has no bearing on Theology, as regards conduct it is eminently encouraging, and the general outcome of Evolution appears to be as Darwin himself pointed out that those Communities which include the greatest numbers of the most sympathetic members will flourish best. In these and other points of view, Science, and even those branches which seem to have the least practical application, are

Dr. Wallace, one of the two creators of the theory, and of Sir Joseph Hooker, who brought it into the world, is in itself enough to render our meeting memorable, and to ensure its success. Among the other Medallists to whom we render due honour to-day, while we regret the absence of Prof. Haeckel and Prof. Weismann, those valiant champions of evolution, we rejoice to have with us Prof. Strasburger, representing in our own day the great school of Hofmeister, who, by his unequalled morphological

orderly advance of the organic universe. Under the dominating genius and untiring experimental research of Darwin the truth of Natural Selection as one of the powerful factors in evolution was established and remains to us; but this fact is not the measure of the value of the first idea and after demonstration. There was here the germ of a revolution in human thought, and the debt we owe to Darwin and Wallace is that their thought and work, more particularly the thought and work of Darwin, have

, when I first made myself master of the central idea of the 'Origin' was, 'How extremely stupid not to have thought of that!' A few years, however, brought conviction, and writing in 1878 Mr. Darwin was able to say that there was almost complete unanimity among Naturalists about the truth of evolution. As regards the Joint Memoir and the 'Origin of Species,' no doubt the attacks of Theologians were mainly due to the belief, still widely entertained, that Evolution was incompatible with religion

idea is expressed with equal clearness, as for example in the words If any species should produce a variety having slightly increased powers of preserving existence, that variety must inevitably in time acquire a superiority in numbers. With both authors the key to evolution is at the same time the key to adaptation, the great characteristic by which living things are distinguished. Darwin and Wallace not only freed us from the dogma of Special Creation, a dogma which we now find it difficult to

of those great Pioneers of Biology. The President then addressed Dr. FRANCIS GALTON.

In the study of the first of these factors, Heredity, the work of the present day is characterised by the application of exact methods, whether on biometrical or [page] 2
