PREFACE 



OF the six chapters which constitute this con- 

 cluding volume of G. J. Romanes' Danvin, and after 

 Darwin, three, the first two and the last, were ',n 

 type at the time of his death. I have not considered 

 myself at liberty to make any alterations of moment 

 in these chapters. For the selection and arrange- 

 ment of all that is contained in the other three 

 chapters I am wholly responsible. 



Two long controversial Appendices have been 

 omitted. Those marked A and B remain in accord- 

 ance with the author's expressed injunctions. In 

 a third, marked C, a few passages from the author's 

 note-books or MSS. have been printed. 



The portrait of the Rev. J. Gulick, which forms the 

 front'-spiece, was prepared for this volume before the 

 author's death. Mr. Gulick's chief contributions to 

 the theory of physiological selection are to be found 

 in the Linnean Society's Journal (Z oology > vols. xx
