34 children. 7 (= 19,5 per cent) of these children have plain blue eyes, 

 19 {= 58,4 per cent) have mixed eyes, and 8 (= 22,1 per cent) have 

 plain brown eyes. In spite of the parents having homogeneous eyes 

 all 3 main groups of eyes are found in the children. Plain blue eyes 

 are «found in an average of Vi of the children, in some more 

 than '^li plain brown eyes are found, and in the remaining half 

 the eyes of the parents are found. Thus the proportions come 

 close to the proportions well known from the Mendelian principles 

 of segregation. We may be allowed to conclude that the small 

 deviation from the Mendelian proportions are mostly due to the 

 fact that the material is too small. My investigations cannot give any 

 positive answer to the question whether all types of mixed eyes behave
