It would be tedious to cite testimonies at length, but, in addition to M. de Quatrefages who has made a full and careful study of the whole question, [_Charles Darwin et ses précurseurs Français_, and _Les Emules de Darwin_] may be mentioned such continental scholars as Blanchard [_La vie des êtres animés_], Wigand [_Der Darwinismus und die Naturforschung_, etc.], Wolff [_Beiträge zur Kritik der darwinschen Lehre_], Hamann [_Entwicklungslehre und Darwinismus_], Pauly [_Wahres und Falsches an Darwins Lehre_], Driesch [_Biologisches Zentralblatt_, 1896 and 1902], Plate [_Bedeutung und Tragweite des Darwinschen Selektionsprincip_], Hertwig [_Address to Naturalist Congress_, _Aachen_, 1900], Heer [_Urwelt der Schweiz_], Kölliker [_Ueber die darwin'sche Schöpfungstheorie_], Eimer [_Entstehung der Arten_], Von Hartmann [_Wahrheit und Irrthum im Darwinismus_], Schilde [_Antidarwinistisches im Ausland_], Du Bois-Reymond [_Conference_, August 2, 1881, etc.], Virchow [_Freiheit der Wissenschaft_, etc.], Nägeli [_Mechanisch-physiologische Theorie der Abstammungslehre_], Schaafhausen [_Ueber die anthropologischen Fragen_], Fechner [_Ideen zur Schöpfungs-und Entwicklungsgeschichte der Organismen_], Jakob [_Der Mensch_, etc.], Diebolder [_Darwins Grundprinzip_, etc.], Huber [_Die Lehre Darwins kritisch betrachtet_], Joseph Ranke, and Von Bauer,--all of whom either reject Darwinism altogether, or admit it only with fatal reservations. Special weight must attach to the adverse verdict of M. Fabre, styled by Darwin himself "that inimitable observer," who declares that he cannot reconcile the theory with the facts he encounters.[235] It must be sufficient to quote one or two of our own countrymen, whose utterances will enable us to form an opinion as to the true scientific status of the doctrine. We may begin with Huxley, the great popular champion of Darwinism, who did more than any other man to spread the new doctrine. Yet, strange to say, he seems never to have really accepted its fundamental tenet himself, always appearing very shy of Natural Selection, and carefully abstaining from committing himself to any responsibility for it. Thus in his treatise on _Man's Place in Nature_, he thus explains his position in its regard:
