Nothing is to be gained for the understanding of our problem of Evolution if we multiply this enormous number of generations by ten or any other multiple. We are not able to conceive changes so small as those which necessarily have existed between Pithecanthropus and man if the whole striking difference is analysed into 17,000 steps. Every one of these stages in the modifications of the muscles, the skeletal framework, increase of brain, shortening of the trunk, lengthening of the legs, improvement of the hands, loss of the hairy coat, etc., is truly microscopical, imperceptible, just as the Evolutionist imagines the whole process to have been. Again, where is the difficulty implied by the change from an air-breathing, in many structural points half-amphibian, fish into a primitive land-crawling four-footed creature, if we are allowed to resolve the transformation into 1,000,000 stages? So far from there being any difficulty, rather does it appear questionable if so many infinitely small changes have been necessary to bring about this result. One thousand years make apparently no difference in the evolution of animals, nor does one second change the aspect of the hands on the face of a clock, nor did Julius Cæsar's commission of scientific men appreciate the error of about eleven minutes in the length of the year beyond its real value; but now the Russians are, owing to this neglect, nearly two weeks behind the civilized nations. THE END. BILLING AND SONS, PRINTERS, GUILDFORD. By PROFESSOR ERNST HAECKEL MONISM; OR, The Confession of Faith of a Man of Science. Translated from the German by J. D. F. GILCHRIST. _Crown 8vo., cloth. Price 1s. 6d. net._ 'We may readily admit that Professor Haeckel has stated his case with the clearness and courage which we should expect of him, and that his lecture may be regarded as a fair and authoritative statement of the views now held by a large number of scientifically educated people.'--_Times._ 'The Monism, which is the substance of his faith, is thus defined by him: "Our conviction that there lives one spirit in all things, and that the whole cognizable world is constituted, and has been developed, in accordance with one common fundamental law." As the confession of a distinguished man of science, this little work deserves to be read.'--_North British Daily Mail._ 'This "Confession of Faith" was delivered by the great German scientist, its author, as an extemporaneous address at Altenburg rather more than two years ago. There are, no doubt, a large number of English readers who will welcome a translation, for this "connecting of religion and science" has long troubled many earnest students of modern science.'--_Publisher's Circular._ 'This is a little book of great daring, an example of the wild speculative flights of one of the very ablest and greatest of our contemporary men of science.'--_Aberdeen Free Press._
