graphs. The results of crossing albino negroes with 

 normally pigmented members is also urgently 

 required. The same considerations hold with regard 

 to human albinism generally. Much of the published 

 records are incomplete and not precise enough. The 

 case of Josephine Chassot described on p. 77 is an 

 example of this. She is described in the original 

 publication as " affected with albinism," as having 

 " pink eyes (pupils)," but " with peculiar lilac- 

 coloured irides," and as having a " very white skin." 

 But nothing is said about her hair colour. When 

 described in comparison with her sister, who is stated 

 to be dark, she is said to be fair (blonde). Such a 

 description may mean that her hair is flaxen or white. 

 The other albinoes in this pedigree are simply des- 

 cribed as " albinoes," or as being " affected with 

 albinism." But as to whether they are complete 

 albinoes having no pigment at all, or are so-called 

 partial albinoes having flaxen hair, we are left to 

 infer. 



Note to p. 68. — A definition of " Eugenics " by its 

 author, Mr. Francis Galton, may be found in 

 " Nature," Vol. LXX., p. 82, 1904. " Eugenics is the 

 science which deals with all influences that improve 

 and develope the inborn qualities of a race." The 

 essential basis upon which " Eugenics " is founded 

 exists in the consideration of certain postulates which 

 all will accept, i.e., " that it is better to be healthy 

 than sick, vigorous than weak, well-fitted than ill- 

 fitted for their part in life. In short, that it is better 

 to be good rather than bad specimens of their kind.
