THE RELATION OF THE ENDOCRINE 



GLANDS TO HEREDITY AND 



DEVELOPMENT! 



Since the object of the Eugenics Research 

 Association is the advancement of knowledge 

 that will contribute to the impi-ovement of the 

 human race by inheritance, its members can 

 scarcely fail to be interested in the discussions 

 that are now going on regarding the glands of 

 internal secretion and their relations to hered- 

 ity. As a medical man, deeply interested in 

 the problems of constitution and of condition 

 and profoundly impressed with the recognizable 

 influences of internal secretions upon form and 

 function in both normal and jjathological states, 

 I welcomed the suggestion of Dr. Davenport 

 that I deal in my presidential address v.'ith the 

 topic announced. The progress of research in 

 endocrine domains and in heredity has of late 

 been so rapid that no single person can keep 

 pace with its strides. My remarks, therefore, 

 will make no pretence to completeness of dis- 

 cussion of the reciprocal relations of heredity 

 and endocrinology. They are intended rather 

 to direct the attention of the members of the 

 association to some of the more important facts 

 that have been established and to stimulate 

 interest in some of the newer problems that are 

 emerging and clamoring for solution. 



THE ENDOCRINE ORGANS AND THEIE PRODUCTS 



It is only comparatively recently that the 

 significance of the so-called ductless glands and 

 of the substances they manufacture has become 

 recognized, but, in a very short time, a consid- 

 erable body of knowledge concerning their 

 structure, their functions and their inter-rela- 

 tions has been accumulated. At the moment, 

 studies of the internal secretions, or, as many 

 now call them, the "incretions," are, on ac- 



1 Presidential address at the tenth annual meet- 

 ing of the Eugenics Research Association, held at 

 Cold Spring Harbor, Long Island, June 10, 1922.
