of one boy faintly duplex, was herself simplex with a duplex mother 

 and a simplex father. 



The father of the male parent was simplex and the mother unknown. 



The father G. B. had had a previous family (Family I) of eleven 

 children by his first dark duplex wife ; of these eleven children eight 

 were dark brown and three simplex, and no cases of ray or irregular 

 pattern occurred in this first family. 



In the "G" family (Frake), Fig. Ill, the father (of unknown parental 

 eye-colour) is a ray-duplex of self-type, that is to say the iris is dark 

 brown leaving some ray or lozenge-shaped blue spaces round the pupil 

 in both eyes. 



The mother is a self-coloured duplex of yellow tint. 



Of the nine children one son E. F. has a dark brown, almost black 

 ray in the outer side of the left iris, the remainder of the iris and the 

 other eye being light brown. 



One daughter L. F. has multiple dark brown rays covering the 

 greater part of the inner half and part of the outer half of the left iris, 

 the remainder being blue and the right eye dark brown. 



One son A. F. has a dark patch in the upper and outer part of the 

 right iris, the remainder of this and the left iris being light brown 

 ring-duplex.
