PREFACE

Of the six chapters which constitute this concluding volume of G. J. Romanes' Darwin, and after Darwin, three, the first two and the last, were in 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 arrangement of all that is contained in the other three chapters I am wholly responsible.
