Ordinary prostitutes are about as frequently deficient as are those in reformatory institutions, if we may judge by an important study of women who were sex offenders but not in institutions for delinquents. The report is by Dr. Clinton P. McCord, health director of the Board of Education at Albany (_35_). One group consisted of fifty cases of sex offenders who were not legally delinquents at the time but were living in houses of ill-fame. Their ages ranged from 22 to 41 with an average age of 27. Nine of these (18%) tested IX or under with the Binet 1911 and 18 tested X, a total of 54% presumably and doubtfully deficient. Another 38 cases were staying at a House of Shelter where most of them had been sent by the courts. Nineteen of these tested IX or under (50%), while 13 more tested X, a total of 84%. Since their ages ranged from 12 to 40 years with an average of 18 we cannot tell how many might be above the borderline on account of an age less than 15 years, but probably very few. A third group consisted of 9 street walkers and 3 wayward girls. Among these 7 tested presumably or doubtfully deficient. The McCord study of prostitutes not legally delinquent at the time of examination is confirmed by the Virginia State Board of Charities and Corrections in a special report to the General Assembly which gives the results of examining the prostitutes in an entire segregated district in one of the Virginia cities (_58_). Its table shows that, among 120 of these women, 43, or 36%, tested approximately under our borderline for the presumably deficient, while 67 cases, or 56%, tested below approximately our borderline for the presumably passable intellects. These results are similar to Weidensall's[19] findings among the unselected group of unmarried mothers in the Cincinnati General Hospital. While she does not give the number tested with the Yerkes-Bridges scale, she indicates that 48% tested as low-grade morons or worse, which should correspond to a test age of IX or lower. Twenty-two per cent. had intelligence coefficients of .50 or less and 32%, from .51 to .70. A _Study of Fifty Feeble-Minded Prostitutes_[20] by Mary E. Paddon gives an admirable summary of the social history of prostitutes who tested deficient.
