In order to find a basis for the sum of the resemblance I have calculated the differences among all Dr. Fürst's test-persons, not related among themselves, by comparing every female test-person with all the other unrelated females; the same has been done for the male test-persons. The most marked difference is found in those cases where the two test-persons compared have no associative quality in common. All the groups are calculated in percentages, the greatest difference possible being 200/15 = 13·3 per cent. * * * * * I. The average difference of male unrelated test-persons is 5·9 per cent., and that of females of the same group is 6 per cent. II. The average difference between male related test-persons is 4·1 per cent., and that between female related tests-persons is 3·8 per cent. From these numbers we see that relatives show a tendency to agreement in the reaction type. III. Difference between fathers and children = 4·2. " " mothers " " = 3·5. The reaction types of children come nearer to the type of the mother than to the father. IV. Difference between fathers and their sons = 3·1. " " " " " daughters = 4·9. " " mothers " " sons = 4·7. " " " " " daughters = 3·0. [Illustration: FIG. 11. Tracing A. ---- father; ..... mother; ++++ daughter.
