ESSAYS ON THE 

 INTERNAL SECRETIONS 1920 



INTRODUCTION 



FOR MANY YEARS the writer has been especi- 

 ally interested in developing information per- 

 taining to the internal secretions, and in many 

 ways has attempted to further the interest of the pro- 

 fession in the subject. The establishment of the As- 

 sociation for the Study of the Internal Secretions in 

 1916 was the result of his invitations to numerous 

 correspondents to band themselves together in order 

 to exchange views and make possible a bulletin re- 

 flecting the progress in this field. 



While The Harrower Laboratory is a commercial 

 institution, concerned with the production and sale of 

 certain endocrine remedies, its work is by no means 

 limited to this. In fact, the manufacture of these 

 formulas was undertaken in order that funds would 

 be available for research and other work necessary to 

 materialize the writer's ideals. 



Among several efforts to broaden the interest and 

 information on the practical aspects of the internal 

 secretions is a Prize Essay Contest which was an- 

 nounced early in 1920. Five hundred dollars was of- 

 fered to members of the medical profession (and med- 

 ical students) for a series of essays on the internal 

 secretions. This money was divided into five prizes
