In chart A, the central mating is of an alcoholic man with a normal woman who died of tuberculosis. Of their 11 children, 5 are known to be normal, the others died early. Then (B) this man married a feeble-minded woman and of 7 children 3 are certainly feeble-minded, and 2 were, as young children, killed at play, in a fashion indicating a lack of ability to avoid ordinary dangers. Goddakd, 1910. MUSJMNO 2nd HUSBAND MOS MOS. Fig. 33.—Here a feeble-minded woman (of the first generation) has married a normal man and has 4 normal children (except that 1 is alcoholic); then she marries an alcoholic sex-offender (who is probably also feeble-minded) and has 4 feeble-minded children. Here the mental strength of the first husband brought the required strength into the combination, so as to give good children.
