men and women born in Europe. The descendants born in America shows 

 an increase of Nordic and Armenoid elements and a diminution of the 

 Laponoid one. Only the female offspring of the immigrants of Silesia are 

 an exception to this rule. This exception in the female series from Silesia 

 can be explained by the fact that the anthropological analysis of women is 

 more difficult than the analysis of the men. Especially does it apply to the 

 distinct difference of the Northwestern and Mediterranean types. The 

 Armenoid and the Mediterranean elements are too scarce to enable us to 

 reach any conclusion. 



We must suppose that the anthropological difference between the immi- 

 grants born abroad and their descendants born in America is due to 

 the unequal natural increase of the particular anthroploogical types.

children, considering the particular anthropological type of father and 

 mother. 



It is evident that the father as well as the mother of the Nordic type 

 possess the greatest natural increase of children. 



The interesting differences between the figures for births and deaths as 

 compared with the average increase (of 4.7) appear in the marriages of 

 particular types. In order to obtain a stronger marked result we have 

 linked the particular anthropological types according to their affinity in 

 the following groups: the Nordic group (of the Nordic and northwestern 

 types), the Laponoid group (of the Subnordic, the Laponoid and the Preslav 

 types) and the Armenoid group (of the Alpine and Dinaric types). The 

 result is illustrated in table 4. 



This table shows that the Nordic marriages indicate the greatest natural 

 increase of children. This result reveals the fact that the descendants born
