PROFESSOR K. PEARSON AND DR. A. LEE ON 
Appendix II. 
Tables of Eye-colour Inheritance in Man, extracted by Karl Pearson from 
Mr. Francis Galton’s Family Records. 
Table of Tints. 
1 = light blue. 
2 = blue, dark blue. 
3 = blue-green, grey. 
4 = dark grey, hazel. 
5 = light brown. 
6 = brown. 
7 = dark brown. 
8 = very dark brown, black. 
This grouping is not quite in keeping with more recent divisions of eye-colour, but- 
being that adopted by Mr. Galton in his original collection of data, it could not be 
modified in accordance with present practice.
