As has already been pointed out, there is reason to believe that much of this is based in some degree on feeble-mindedness. One of the most remarkable of these is the recent study on degeneracy by Goddard as set forth in his book called _The Kallikak Family_. The record is that of six generations of descendants from an original progenitor to whom the fictitious name of Kallikak has been assigned. This individual, descended from good stock, before his marriage met a feeble-minded girl by whom he became the father of a feeble-minded son. Later he married a normal woman by whom he had normal children. Thus from one normal father have sprung two lines of progeny, one vitiated with feeble-mindedness, the other normal. The comparison may be readily made by drawing up in parallel columns the data as follows: LINE A LINE B In five generations 480 direct In five generations 496 descendants descendants from a normal father from the same normal father as in father and a feeble-minded Line A and a normal mother have the mother have been accounted for following record: as follows: 143 known to be feeble-minded. All but one of normal mentality. 291 mental status unknown or Two men known to be alcoholic. doubtful. 36 illegitimate. One case of religious mania. 33 sexually immoral, mostly Among the rest have been found prostitutes. nothing but good representative citizenship, numbering doctors, 24 confirmed alcoholics. lawyers, educators, judges, traders, etc. 3 epileptics. No epileptics or criminals. 82 died in infancy. Only fifteen children died in infancy. 3 criminals. 8 keepers of disreputable houses. 46 only ones known to ben ormal. Certainly there is abundant food for thought in these two records. If we take still other families of criminal or degenerate antecedents the same multiplication of viciousness, as a rule, is in evidence. Thus, _Margaret, the Mother of Criminals_, has left a progeny of some 700 paupers, prostitutes and criminals, some of the women bearing as many as twenty children. The famous Jukes family, so often cited, with its 310 professional paupers, 300 deaths in infancy, 440 physical wrecks from debauchery, 50 prostitutes, 60 habitual thieves, 7 murderers, and 130 other convicts out of a total 1,200 descendants who have been identified, has alone cost the state of New York $1,250,000 in the care of its criminal, defective and immoral progeny.
