. American breeders magazine. Breeding; Plant breeding; Heredity. HEREDITY OF FEEBLE-MINDEDNESS. 169 woman, but a victim of tuberculosis. The result of that marriage was eleven children, of whom five are known to be normal, the others died young. This man married for his second wife a woman who was alcoholic and feeble-minded, and who had two sisters, a brother, a father, and a mother that were also alcoholic. The result of this union was seven children—three feeble-minded, two that died young, and two that are as yet unknown. It seems to be fairly clear in this case that the father's alcoholism may have caused the physical weakness that led to so many early deaths in the first family, but the mother's defect has been directly transmitted in the second family, with the result that there are at least three feeble-minded children. We might also add the two others that died young, because, according to the definition of Tredgold which describes an idiot as "one who cannot avoid ordinary dangers, " these children were also defective, since they were both killed at play, apparently not being able to protect themselves in a usually harmless game. ©[n]—r—0 (§I^SSS^^&-r<5 rr^T MOS. DAYS L TWINS. Chart VI. Chart VI shows a marked instance of the defect skipping a gen- eration. The maternal grandmother was feeble-minded, her husband was alcoholic, but not one of their children was defective. Indeed, four of them were distinctly normal. However, the mother of our child had had St. Vitus dance, a brother is alcoholic, a sister had had St. Vitus dance, and another hysteria, but mentally, thev were not defective. The father has no history of mental defect in his family; he himself was alcoholic, but his five brothers and sisters and the parents were normal. Nevertheless the result of the union of these two is three feeble-minded children, one still-born, one that died in five days, two miscarriages, and two normals. If we had this family only, perhaps it w
