Successive electroencephalographic records were made of 95 presumably normal children over a period of from five to eight years. A single record was made also of 540 "normal" children between the ages of 4 and 19. In the majority of cases rates stabilize by the eighth year, with a frequency between nine and eleven per second. Females tend to have faster alpha frequencies than males and a larger proportion of low voltage fast records. Correlation between frequence and intelligence could not be demonstrated. In a group of 583 "normal" children 5 per cent had abnormal and 6.9 per cent questionably abnormal records, although some of these were found to be normal a year later. This is a complete detailed study made under the auspices of the Brush Foundation, a valuable reference and example for persons interested in electroencephalography or in the development of children.
