From what has been said, it appears that Darwinism includes three distinct elements. First, evolution; or the assumption that all organic forms, vegetable and animal, have been evolved or developed from one, or a few, primordial living germs; second, that this evolution has been effected by natural selection, or the survival of the fittest; and third, and by far the most important and only distinctive element of his theory, that this natural selection is without design, being conducted by unintelligent physical causes. Neither the first nor the second of these elements constitute Darwinism; nor do the two combined. As to the first, namely, evolution, Mr. Darwin himself, in the historical sketch prefixed to the fifth edition of his "Origin of Species," says, that Lamarck, in 1811 and more fully in 1815, "taught that all species, including man, are descended from other species." He refers to some six or eight other scientists, as teaching the same doctrine. This idea of Evolution was prominently presented and elaborated in the "Vestiges of Creation," first published in 1844. Ulrici, Professor in the University of Halle, Germany, in his work "Gott und die Natur," says that the doctrine of evolution took no hold on the minds of scientific men, but was positively rejected by the most eminent physiologists, among whom he mentions J. Mueller, K. Wagner, Bischoff, Hoffmann, and others.[8] The Rev. George Henslow, Lecturer on Botany at St. Bartholomew's Hospital, London, himself a pronounced evolutionist, says the theories of Lamarck and of the "Vestiges of Creation" have given place to that of Mr. Darwin; "and there are not wanting many symptoms of decay in the acceptance even of his. Not only has he considerably modified his views in later editions of the 'Origin of Species,' distinctly expressing the opinion that he attributed too great influence to natural selection, but even men of science, Owen, Huxley,--and at least in its application to man, Wallace himself,--are either opposed to it in great measure, or else give it but a qualified assent. Thus, it has been the fate of all theories of the development of living things to lapse into oblivion. _Evolution_ itself, however, will stand the same."[9] We find in the "Transactions of the Victoria Institute," a still more decided repudiation of Darwinism on the part of Mr. Henslow. He there says: "I do not believe in Darwin's theory; and have endeavored to refute it by showing its utter impossibility."[10] He defines Evolution by saying, "It supposes all animals and plants that exist now, or have ever existed, to have been produced through laws of generation from preexisting animals and plants respectively; that affinity amongst organic beings implies, or is due to community of descent; and that the degree of affinity between organisms is in proportion to their nearness of generation, or, at least, to the persistence of common characters,
