ARTICLES only in the measurements at ages 6, 9, and the magnitudes of the differences was noted as the boys grew older. In general, the boys exposed at age 5 years or below appear to have growth curves parallel to those of the unexposed group, but remain 5 to 10 cm shorter in stature than unexposed boys of the same age (Fig. 1). The notable exceptions to this generalization are 2 of the 4 boys exposed at 16 to 17 months of age. Both of these boys, at age 10 years, are roughly comparable in stature to the 6-year-old un- exposed boy.
