Chart I shows the descendants of a feeble-minded woman who was married twice. Her first husband was normal. There were four normal children, one of whom is alcoholic. This alcoholic son married a normal woman and produced two feeble-minded and three normal children. This is another instance of the defect skipping a generation, being transmitted by the grandmother through the father. The second marriage of this feeble-minded woman was with an alcoholic and immoral man. The result was four feeble-minded children. One of these became alcoholic and syphilitic and married a feeble-minded woman. She was one of three imbecile children, born of two imbecile parents. The result here could, of course, be nothing but defectives. There were two stillborn, and three that died in infancy. Six others lived to be determined feeble-minded. One of these was a criminal. Two are in the institution at Vineland. The mother’s sister also has a feeble-minded son. [Illustration: CHART II _A_.] Chart II (in two parts) is in some ways the most astonishing one we have. There are in the institution at Vineland five children representing, as we had always supposed, three entirely independent families. We discovered, however, that they all belonged to one stock. In Chart II, _A_, the central figure, the alcoholic father of three of the children in the institution, married for his third wife a woman who was a prostitute and a keeper of a house of ill fame, herself feeble-minded, and with five feeble-minded brothers and sisters. One of these sisters is the grandmother represented on Chart II, _B_. On _A_ it will be seen that this alcoholic man was four times married. He comes from a good family but was spoiled in his bringing up, became alcoholic and immoral--a degenerate man. His first wife, however, was a normal woman and it is claimed that the two children were normal. For his second wife, he took out of the poorhouse a feeble-minded woman. Her children were: two normal, one that died young, and one feeble-minded. He married the third time. The woman was the prostitute above referred to. She had three illegitimate children, all feeble-minded. After their marriage, they had three children, all of whom are feeble-minded. Two of these are in this institution. The father then deserted this woman and married a fourth wife, who is alcoholic and a prostitute. Of this union, however, there are no children. There is, moreover, very strong evidence that he is the father of the third child in this institution by another woman, who is also feeble-minded. [Illustration: Chart II _B_.]
