XIII 

 THE RECAPITULATION THEORY 



As my theme for this morning's address I have 

 selected the Development of Animals. I have 

 made this choice from no desire to extol one par- 

 ticular branch of biological study at the expense of 

 others, nor through failure to appreciate or at least 

 admire the work done and the results achieved in 

 recent years by those who are attacking the great 

 problems of life from other sides and with other 

 weapons. My choice is determined by the neces- 

 sity that is laid upon me, through the wide range 

 of sciences whose encouragement and advancement 

 are the peculiar privilege of this Section, to keep 

 within reasonable limits the direction and scope of 

 my remarks ; and is confirmed by the thought that, 

 in addressing those specially interested in and 

 conversant with biological study, }^our President 

 acts wisely in selecting as the subject-matter of his 

 discourse some branch with which his own studies 

 and inclinations have brought him into close 

 relation.
