PREFACE. 



The two studies included in the present volume are the second and 

 third, respectively, of a series of studies on the Feebly Inhibited. The 

 first (on Violent Temper and its Inheritance) was published in the 

 Journal of Nervous and Mental Diseases for September 1915. These 

 studies of which two are in preparation are principally the outcome 

 of the analysis of a large amount of data collected by trained ' ' eugenics 

 field- workers " acting in connection with various State institutions, and 

 above all with those for wayward girls. Acknowledgment is due to 

 those superintendents and to the field-workers who have co-operated 

 in the study. The following institutions paid part of the expense of 

 collecting the data: 



1 . State Industrial School for Girls, Lancaster, Massachusetts ; Mrs. Amy 



F. Everall, Superintendent; Mrs. G. W. Hathaway and Dr. Wilhel- 

 mine E. Key, field-workers. 



2. New Jersey State Home for Girls, Trenton, New Jersey; Mrs. 



Elizabeth V. H. Mansell, Superintendent; Miss Z. E. Udell, field- 

 worker. 



3. New Jersey State Village for Epileptics; Dr. David F. Weeks, Super- 



intendent; Mrs. D. L. F. Woodward and Miss Sadie C. Devitt, 

 field-workers. 



4. New Jersey Home for Feeble-minded Women ; Dr. Madeline Hallowell, 



Superintendent; Miss Helen T. Reeves, field- worker. 



5. The Glen Mills (Pennsylvania) Schools, Girls' Department; Miss 



Martha P. Falconer, Superintendent; Miss Ruth Wanger, field- 

 worker. 



The cost of training the field- workers was met by Mrs. E. H. Harri- 

 man, founder and principal patron of the Eugenics Record Office, and 

 Mr. John D. Rockefeller, who paid also the salaries of many of the 

 field- workers. This generous assistance is gratefully acknowledged. 



A word may be said as to the term "feebly inhibited" used in these 

 studies. It was selected as a fit term to stand as co-ordinate with 

 "feeble-minded" and as the result of a conviction that the phenomena 

 with which it deals should properly be considered apart from those of 

 feeble-mindedness. There is no question of the well-developed intelli- 

 gence of some of these feebly inhibited individuals. No doubt the 

 content of the term mind could be stretched to cover these emotional 

 phenomena; practically, I think it helps to consider separately the 

 heredity basis of the intellect and the emotions. It is in this conviction 

 that these studies are submitted for thoughtful consideration. For, 

 after all, the chief problem in administering society is that of disordered 

 conduct, conduct is controlled by emotions, and the quality of the 

 emotions is strongly tinged by the hereditary constitution.
