go THE TREND OF THE RACE 
after they have been guilty of more than one offense, show, when 
tested by the Binet and several other tests, a marked inferiority 
in mental development. The proportion of feeble-minded was 20 
per cent, ‘‘but probably at least 50 per cent of delinquents are 
totally incapable of being taught to look after themselves in an 
environment as unfavorable as the one from which they came.” 
The results of Ordahl’s investigation of the cases brought before 
the Juvenile Court of San José, California, reveal the fact that 
“a5 per cent of the criminal dependents, 45 per cent of the 
minor delinquents, and 75 per cent of the adult delinquents are 
feeble-minded. If the feeble-minded and borderline group are 
combined, then 45 per cent of the minor dependents and 60 per 
cent of the minor delinquents are below average-normal intelli- 
gence. In both the minor dependent and the minor delinquent 
group 60 per cent of the parents, so far as data were available, 
are either alcoholic, immoral, feeble-minded or insane.” 
Ordahl’s study of 341 delinquent boys of a school at St. 
Charles, Ill., to which boys are committed for various offenses, 
reveals the existence of nineteen and six-tenths per cent of 
distinctly feeble-minded cases; 20.8 per cent were of very dull 
mentality ‘“‘and many of these would probably prove on further 
study to be feeble-minded ”’; 15.5 per cent were borderline cases, 
the remaining 44.1 per cent. being of normal mentality. J. H. 
Williams finds that out of 215 boys in the Whittier State School 
the distribution of intelligence was as follows: 
Feeble-minded..... ........... 32 per cent. 
Borderline... ...............0.. Br! SOR 
Dull Normal................... 7) ed

Dr. Haines’ reports on the intelligence tests of 671 boys from 
the Ohio Boys Industrial Home, and 329 girls of the Ohio Girls 
Industrial Home, reveal much the same condition. All the in- 
mates were tested by both the Binet-Simon and the Yerkes- 
Bridges Point Scale tests. The proportion graded as feeble-
