considered, 4 families are left, where both parents and the offspring 

 have mesocephalic indices. The average index of the parents will 

 then be 78,4 and that of the offspring 77,7. As also in this case some 

 of the offspring are children V2 ii 1 index has to be deducted. The 

 table confirms the fact already knowui, that a large number meso- 

 cephalic individuals with an average index of 77 is to be found in this 

 population. All of the parents are most likely homozygotes (MM X 

 MM = 4 MM). 



In table 8 we meet again with a type similar to the one in table 

 6, but the process of segregation runs here in another direction. Here 



TABLE 7. 

 Both parents and all offspring have dolicho-mesocephalic index. 



we meet a whole series of offspring with considerably lower indices 

 than any of the parents. The average index of one of the parents 

 is very low being only 72,i. The other of the parents has in 4 cases 

 a higher index, viz. 79 up to 81; in the remaining 2 cases the other 

 of the parents has also a low index. In other words, one of the pa- 

 rents is phsenotypically dolichocephalic, the other either dolichocepha- 

 lic, mesocephalic or brachycephalic. As to the offspring the result will 

 be the same in every case. Some of the offspring will be largely dolicho- 

 cephalic, the rest mesocephalic. There is found no indication of 

 brachycephaly in the offspring. 



I conclude from this fact that neither of the parents has had 

 brachycephalic blood in his veins. It has been showed already (tables 

 3, 4, 5 and 6) that the brachycephalic type is dominant to the meso- 

 cephalic as well as to the dolichocephahc biotype. If therefore any of
