In 1929 I have published a work "Anthropogenetische Auslese" based 

 on an examination of Polish population, in which I have stated the tend- 

 ency to homogamy in the marriages of particular types. Furthermore I 

 stated that this tendency to the homogamy is not the same in the respective 

 marriages of the particular types. The investigation of people of Texas, 

 on the contrary, has established no homogamy. This fact can be explained 

 as follows. Homogamy appears among the old population, where the 

 anthropological types owing to their different psychical qualities have 

 formed different social strata. It is not the case in Texas, where the oldest 

 immigration exists scarcely for seventy-five years and was drawing on the 

 new settlers in later time. 



Table 5 shows us the coefficients of homogamy given by 



Q = sm w -Q> 



where 



ad — be 



Q! = 



V(a +b ) (c + d) (a + c) (b + d) 



As a general result of this work we must add that our studies do not 

 approve of Madison Grant's opinion concerning a racial deterioration of 

 American people in the later time. By no means is this opinion quite right, 

 if we regard the American people of Polish origin.
