Applying the estimation method of the distribution function of Rohrer-Index at each level of height by Ichimura, mean scores of R-Index at each level of height of each chronological age, from 8 to 18, male and female, were estimated. And the developmental transition of the mean score of R-Index at each level of height from eight years old to eighty years old was considered. The followings were presented as the results. 1) During childhood and middle adolescent ages where the body development is regular the higher the estimated mean score of R-Index is at the lower height. During the preadolescent ages where the development is accelerated the estimated mean score of R-Index is lower at the highest and the lowest levels of height, and the highest mean score is appeared at a middle level of height. 2) Considering the mean scores of R-Index depend on the levels of height, the traditional standard of the evaluation of fatness and thinness taking (the mean of weight)÷(the mean of height)^3 as the standard score of a group is improper. The table of the standard score of R-Index at each level of height is presented. 3) It is found that on the continuum of height there are such specific pints above where the development of height is more facilitated than weight and below where the development of weight is more facilitated than height without distinction of age.
