The Improvement of Eacial Stock 



A vast new territory of inquiry and achievement, as yet totally 

 unexplored, is opened by the endocrines to the eugenists, and 

 those idealists whose most earnest aspiration is the improvement 

 of racial stock as a necessary preliminary to improvement of 

 racial life. Beginning with Galton, they have brought to light 

 a great collection of data to prove that human traits and facul- 

 ties, good and bad, are inherited. Ability has been shown to run 

 in certain families and degeneracy in others. Yet all of the 

 practical net result has been summed up in the term "negative 

 eugenics," the eugenics of prohibition and warning. 



Now the concept of personality, as woven around a system of 

 chemical reflexes, handed on from generation to generation, is 

 bound to change all that, and to create a structure of positive 

 eugenics. It has been said that what radium is to chemistry, the 

 internal secretions are to physiology. Just as radium enlightens 

 the chemist about the history of matter, and the integrations 

 and disintegrations constituting the life of an element — the in- 

 ternal secretions illuminate the history of the individual as part 

 of the life of the race, and of its integrations and disintegrations. 

 Seeing the individual as a system of chemical substances inter- 

 acting will assist enormously to predict the nature, character 

 and constitution of his descendants, which is essentially what 

 the eugenist is after. 



The study of matings, the heart of the matter, will coi 

 itself with the investigation and comparison of the kind of en- 

 docrine personalities that mate, the internal secretion pr. 

 inances that cross, and the consequent endocrine personal: 

 the offspring. D. iflg upon p! md physiognomy, 



ttomy and function, mind and behaviour will so be 

 co-ordinated as no eugenist has hitherto succeeded in d 

 Laws of endocrine inheritance will emerge that will bring the 

 control of heredity within IllftiHimblll di.-tance. Standards and 

 norms of a new kind would be obtain
