+Director of the New Jersey State Village for Epileptics at Skillman, U.S.A.+ Explanation of Symbols used in the Charts. Male individuals are indicated by squares and females by circles. The members of each fraternity are connected by the same horizontal line. The fraternity line is connected by a vertical line to the line joining the symbols representing the father and mother. Illegal unions and illegitimate children are shown by dotted lines. As an aid in tracing the patient's immediate family, a green line is used to connect the direct ancestors on the paternal side, and a red line on the maternal side. The red squares and circles indicate epileptics, the green the insane, the black the feeble-minded, and purple the criminalistic. The figures directly above the fraternity line indicate the rank in birth, a figure inside a square or circle shows the number of individuals of that sex. A black dot suspended from the fraternity line stands for a miscarriage or a stillbirth. A line underneath a square or circle shows that institutional care has been received. The hand points out our patient. The following letters indicate the different conditions: A, alcoholic; B, blind; C, criminalistic; D, deaf; E, epileptic; F, feeble-minded; I, insane; M, migrainous; N, normal; P, paralytic; S, syphilitic; T, tubercular; W, wanderer, tramp; d, died; b, born; inf, infancy; Sx, unchaste. [Sidenote: D 1] This chart shows very clearly the dangerous results of a marriage in which both of the +parents are epileptic+. Of the four children the first three were epileptic, and the fourth, a boy, who died at the age of nine, was feeble-minded. All four of these children were cared for at public expense, two are patients at the New Jersey State Village for Epileptics, and the other two were wards of the Children's Home Finding Society. The epileptic father is dead, and the mother married again to an alcoholic man. When last heard of she had another child. [Sidenote: D 2] An +epileptic+ woman, married to a +feeble-minded man+, is responsible for the large number of defectives shown on this chart. The principal mating is that of one of the epileptic daughters of this woman, who, like her mother, married a feeble-minded man. Eight children resulted from this marriage; one died before two years of age, the other seven were epileptic, the five who are living are patients at the New Jersey State Village. Two of the girls in this fraternity had illegitimate children before receiving proper care. This family is undoubtedly a branch of a family of defectives, most of whom live in an adjoining State.
