      Measurements of 212 microcephalic children show them to be consistently retarded in height when compared by age and sex with 12,000 healthy children in the public schools. Abnormally small head sizes in microcephalic children have a significant correlation with intelligence quotients when degrees of microcephaly are plotted against degrees of mental retardation as measured in intelligence quotients.
