The Princeton University Press 



invites attention to the volumes described 

 in this and the following pages. They rep- 

 resent modern bookmaking at its best, in 

 respect of scholarly and useful content, care- 

 ful typography and durable binding. The 

 aim throughout has been to produce, at a 

 reasonable price, books worth writing, 

 printing, publishing and reading in these 

 days of national stress and economy. 



HEREDITY AND ENVIRONMENT IN THE DEVELOP- 

 MENT OF MEN. By Edwin Grant Conklin. 

 $2 net ; by mail, $2.10. 



Is a man ruled by his chromosomes? Is it use- 

 less to revolt against the predestination .and fore- 

 ordination of heredity? Professor Conklin is too 

 human a scholar to counsel surrender. His book 

 has not only had a notably large sale among gen- 

 eral readers, but has been adopted as a textbook or 

 for collateral reading by more than thirty colleges 

 and universities. Its science is correct and ad- 

 vanced, its text is eminently readable, and its con- 

 clusions are positive and helpful.
