INHERITANCE OF MENTAL DEFECTS AND DISEASE 31 
the best families in their state, the descendants of colonial gover- 
nors, signers of the Declaration of Independence, soldiers and 
even the founders of a great university. Indeed, in this family 
and its collateral branches, we find nothing but good representa- 
tive citizenship. There are doctors, lawyers, judges, educators, 
traders, landholders, in short, respectable citizens, men and 
women prominent in every phase of social life. They have 
scattered over the United States and are prominent in their 
communities wherever they have gone. Half a dozen towns in 
New Jersey are named from the families into which Martin’s 
descendants have married. There have been no feeble-minded 
among them; no illegitimate children; no immoral women; only 
one man was sexually loose.” 
In sharp contrast to this branch of the family stand the descend- 
ants of the feeble-minded girl. Of these 480 have been traced. 
“One hundred and forty-three of these,”’ says Goddard, “‘we have 
conclusive proof were or are feeble-minded, while only forty-six 
have been found normal. The rest are unknown or doubtful. 
Of these descendants there have been 36 illegitimate, 33 sexually 
immoral, mostly prostitutes, 24 confirmed alcoholics, 3 epileptics, 
82 died in infancy, 3 criminals, 8 kept houses of ill fame. The 
Kallikaks married into other families, usually of their own type, 
producing 1,146 individuals. ‘Of this large group,” says God- 
dard, ‘“‘we have discovered that two hundred and sixty-two 
were feeble-minded, while one hundred and ninety-seven are con- 
sidered normal, the remaining five hundred and eighty-one being 
still undetermined.” 
The history of this family is a long tale of feeble-mindedness, 
alcoholism, poverty and prostitution. Children were numerous, 
but although infant mortality was high, the family increased 
rapidly in successive generations. Wherever the Kallikaks 
wandered, whether in the backwoods or in the slums of cities they 
retained the same characteristics. 
There are several Kallikak families, several of which, such as 
the Nams, Pineys, Hill Folk, Tribe of Ishmael, Zeroes, etc., 
show little but a monotonous repetition of the same history
