HEREDITY AND DEVELOPMENT OF NAVAL OFFICERS. 



TABLE 10. Showing for the respective histories the frequency of occurrence of various occupations 

 among the brothers of the father and the mother respectively of the propositus. 



1 Excluding a number of the less important English army officials. 



TABLE 11. Absolute and percentage frequency of occurrence of each of several classes of 

 occupations among sons of the brothers and the sisters, respectively, of the proposituses. 



In comparing for the families of naval officers the contribution of the 

 paternal and maternal sides we should first compare the occupation of male 

 relatives on the two sides holding similar relationship to the propositus, and 

 accordingly we compare the brothers of the father and of the mother. 

 Unfortunately the number of such relatives of which the occupation is 

 known is not large on either side larger on the paternal than the maternal 

 just because biographers always lay more stress on the paternal side.
