*The "Reference No." in this and following tables refers to the case number and generation of the 

 original data filed at the Eugenics Record Office. B, Bermuda; J, Jamaica; L, Louisiana. 



Altogether, determinations were made on 18 negroes, and gave 

 proportions of black in the skin color ranging from 37 to 78. The fre- 

 quencies of the various classes of the black element in skin color, of the 

 various grades of the white element, and of the combination of N+R 

 grades are given in sections Nos. 1, 2, and 3 respectively of table 3.
