We present the results in only one of the psychologic tests given, namely, the Stanford revision of the Binet test. In spite of the various criticisms leveled at this procedure, it is perhaps the most valid and reliable single index of abstract intelligence available. The general use of this test and the ease with which the results may be interpreted further recommended it to us.
