Thelines on Figures 15 and 16 represent the best
fitting linear relationships plotted by the leastsquares method. The points representing the
markedly growth-retarded boys and showing their
early response to thyroid hormone administration
can be recognized by comparison with Figures 31
to 33. The graphs continueto indicate that in the
Marshallese children the skeletal age values at
comparable chronological ages are lower (by
about6 to 12 months) than the normsfor American children presented by Greulich and Pyle.15
The interpretation of growth data from the exposed Rongelapchildren has been complicated by
partial or total thyroidectomies in those children
developing nodules (see Thyroid Findings, below)
and by the administration of thyroid hormoneto
the whole exposed Rongelappopulation since September 1965. The response of certain individual

hypothyroid children to thyroid hormoneis readily
seen in the growth curves (Figures 31 and 32).
The increase in yearly growth rate in males exposed at <5 years of ageis significantly greater
after thyroid treatment (<C0.05) than in unexposed males of comparable age during the sameperiod (based on an analysis of variance using weighted
squares of means of yearly growth increments).
In orderto probethefeasibility of conducting
psychometric tests, the IPAT (Institute of Personality and Ability Testing) Culture Fair Intelligence Test, Scale 2, Form A? was given in 1969
to a group of Marshallese subjects on Rongelap
Island and to another group on EbeyeIsland. This
particulartest is designed to be comparatively immuneto “contamination by accidents of social,
educational, and racial background,”!” and has been
used before in several groups of Micronesians.*8
