Number of eminent men in each degree of kinship to the most eminent man of the family (85 families). B. The preceding column raised in proportion to 100 families. C. Number of individuals in each degree of kinship to 100 men. D. Percentage of eminent men in each degree of kinship to the most eminent member of distinguished families ; it was obtained by dividing B by C and multiplying by 100. KE. Percentages of the previous column reduced in the proportion of (286 — 24,1 or) 242 to 85, in order to apply to families generally. Table II. also gives materials for judging of the com- parative influence of the male and female lines, in con- veying ability. Thanks to my method of notation, it is perfectly easy to separate the two lines in the way I am about to explain. I do not attempt to compare relations in the first degree of kinship—namely, fathers with mothers, sons with daughters, or brothers with sisters, because there exists no criterion for a just comparison of the natural ability of the different sexes. Nay, even if there were means for testing it, the result would be falla- cious. A mother transmits masculine peculiarities to her male child, which she does not and cannot possess; and, similarly, a woman who is endowed with fewer gifts of a masculine type than her husband, may yet contribute in a larger degree to the masculine intellectual superiority of her son. I therefore shift my inquiry from the first, to 1 That is to say, 286 Judges, less 24, who are included as subordinate members of the 85 families.
