The Tables for the first five years are a composite of the figures by Holt (compiled from several hundred hospital and private practice cases in New York City), the American Medical Association (compiled from several thousand cases in 23 States), the Life Extension Institute, and the Better Babies’ Bureau of the Woman’s Home Companion. In the main, the minimum figures are those of Dr. Holt, the maximum those of the Woman’s Home Companion. The figures of Dr. Freeman from 278 children in private practice (see page of Charts) are from 5 to 10 per cent higher than the maximum given in the Tables, for height and weight.
All measurements are without clothing.
