minant to the mesocephalic type, which therefore, if the conclusion is 

 correct, is recessive to both the other types. 



There are few contributions touching upon this subject. The only 

 material of any importance known to me is the one collected in the 

 Faroes by Dr. F. Jörgensen \ 



The material is very large containing 280 families with 935 

 children altogether. On account of the great bulk of material a splendid 

 insight is given here into the subject. At that time, however, the

 One of the parents or both of them have indices higher than 83,o. 



Mendelian laws were but little known. He has therefore only stated 

 the different types in the offspring arising from brachycephalic, meso- 

 cephalic or dolichocephalic parents. 



I have therefore found it of interest to look more closely into 

 the material collected by him and to compare his results with my own. 

 He has 68 families, where both parents are brachycephalic. In these 

 families 234 children in all were found in the following proportions 

 with regard to type: 78 % B, 14 % M and 8 % D. 



In most of his couples of parents the index lies between 80,o and 

 83,0. Within these brachycephalic marriages the children have a 

 higher index than the parents, the average index of the sons being 

 83,6, and that of the daughters 84,5. Only in 9 couples one or both 

 parents have an index higher than 83,o. I have placed these in table 

 9. It appears from this table that also in this case the index of the
