IMPROVING THE HUMAN PLANT 



course the selections are not usually made with

 progeny of an improved type; but the inherent 

 affinities that lead to the selection of marriage

Generally speaking, men and women would

But, of course, under actual social conditions, 

 entire freedom of choice is impossible, and no fact

 marriage state and bring forth abundant progeny. 



Indeed, under existing conditions, it is the all
