Dr. Pyle (_46_) has tested the 240 girls at the Missouri State Industrial Home for Girls with his standardized group tests. These girls are from 7 to 21 years of age and his table gives the results with each of six tests. The most significant fact for our purpose is that with the different tests from 50 to 88 per cent. fall below the averages of normal individuals who are three years younger. He says, “Our figures would indicate that about one-third of these delinquent girls are normal and about two-thirds subnormal. Most of them are probably high grade morons.” This is based apparently on 69% being the average of the results of six different tests as to the percentages three years or more retarded from their life-ages. He indicates, however, that 38%, similarly calculated, are within the average deviation of the normal groups for their life-ages. This indicates that the lowest 62% test only as low as we should expect to find the lowest 21% of random groups of corresponding ages. They should certainly not be regarded as testing feeble-minded. (b) WOMEN AND GIRL DELINQUENTS IN COUNTY AND CITY INSTITUTIONS. When we turn to those who are cared for locally in city or county institutions, we find Sullivan (_56_) has examined 104 women and girls held temporarily at the Holloway jail in London, most of whom were between 16 and 25 years of age. Apparently the cases were especially selected for examination and therefore do not represent the general condition there. He was interested, however, in finding the relative amount of deficiency among different classes of these inmates and he gives the detailed results with the Binet 1908 scale on small groups of these different types which we may classify by our standard as follows: Twenty non-criminal, either not guilty or guilty of unimportant offenses, who represent, he thinks, the ordinary conditions among the corresponding working class in this community, 3 presumably deficient, 5 uncertain; twenty criminal by reason of the occasion, 1 presumably deficient, 6 uncertain; twelve impulsive criminals, 1 presumably deficient, 2 uncertain; eight moral imbeciles, 2 presumably deficient, 2 uncertain; twenty-four recidivists, 2 presumably deficient, 8 uncertain; twenty prostitutes, 3 presumably deficient, 8 uncertain. Together these different types of women in jail form a motley group of 104 of whom 12 test presumably deficient, 31 uncertain, a total of 41%.
