{0c} The distinction was merely implicit in his published writings, but has been printed since his death from his “Notebooks,” _New Quarterly Review_, April, 1908. I had developed this thesis, without knowing of Butler’s explicit anticipation in an article then in the press: “Mechanism and Life,” _Contemporary Review_, May, 1908. {0d} The term has recently been revived by Prof. Hubrecht and by myself (_Contemporary Review_, November 1908). {0e} See _Fortnightly Review_, February 1908, and _Contemporary Review_, September and November 1909. Since these publications the hypnosis seems to have somewhat weakened. {0f} A “hormone” is a chemical substance which, formed in one part of the body, alters the reactions of another part, normally for the good of the organism. {0g} Mr. H. Festing Jones first directed my attention to these passages and their bearing on the Mutation Theory. {0i} He says in a note, “This general type of reaction was described and illustrated in a different connection by Pfluger in ‘Pfluger’s Archiv. f.d. ges. Physiologie,’ Bd. XV.” The essay bears the significant title “Die teleologische Mechanik der lebendigen Natur,” and is a very remarkable one, as coming from an official physiologist in 1877, when the chemico-physical school was nearly at its zenith. {0j} “Contributions to the Study of the Lower Animals” (1904), “Modifiability in Behaviour” and “Method of Regulability in Behaviour and in other Fields,” in _Journ.
