EUGENICS THE FUTURE OF MAN 



index, together with the biographies of capable, 

 though hardly gifted, families, may be published. 

 Not for publication will be a collection of biog- 

 raphies of families distinctly below the average in 

 health, mind, or physique. To this end the records 

 of asylums, hospitals, and prisons must be con- 

 sulted. Then we must utilize all the invaluable 

 aid to be afforded by the data of insurance offices. 

 Most important, also, is it to study what I may 

 call the social circulation. We must know the 

 birth-rates of every class in the community, and 

 must determine how far each class is derived 

 from and contributes to its own and the other 

 classes. It is known, in general, that society is 

 an organism which perpetually renews itself from 

 below, but the particular strata which are foremost 

 in reproduction are not known. The highest and 

 lowest strata are constantly replenished from some 

 intermediate levels. Further, Mr. Schuster will 

 endeavor to collect and catalogue the enormous 

 amount of literature already extant which bears 

 on the subject of eugenics, not forgetting to avail 

 himself of the experience of horticulturists and 

 breeders of stock. 



Then, again, there is almost endless work yet 

 to be done in the field of heredity. Notably do 

 we want to know the effect on the offspring of 

 differences in the parental qualities. Mr. Galton 

 also considers desirable a study of Eurasians \ 

 (the descendants of English and Hindoo parents), 

 both as a topic of national importance to Britons
