    <br/>

      
        In several recent publications I have developed, from different points of view, some 
        considerations which tend to bring out a certain influence at work in organic evolution 
        which I venture to call "a new factor." I give below a list of references to these 
        publications and shall refer to them by number as this paper proceeds.

         The object of the present paper is to gather into one sketch an outline of the view of 
        the process of development which these different publications have hinged upon. 
      
    <br/>

      
        The problems involved in a theory of organic development may be gathered up under three 
        great heads: Ontogeny, Phylogeny, Heredity. The general consideration, the "factor" which 
        I propose to bring out, is operative in the first instance, in the field of 
      
      
        <i>Ontogeny</i>
      
      
        ; I shall consequently speak first of the problem of Ontogeny, then of that of Phylogeny, 
        in so far as the topic dealt with makes it necessary, then of that of Heredity, under the 
        same limitation, and finally, give some definitions and conclusions.
