Analyses of weight and height of about 50, 000 school children in Kyoto City revealed that the frequency distribution of weight did not conform to the normal distribution, and the distribution of weight of taller children spreaded out more widely than that of shorter children.Considering these two characteristics of the distribution of weight of school children, the mode, the first and ninth deciles of weight of each height group of boys and girls were calculated in each school grade. Concerning these three indices of weight, the following weight-height relationship for school children was observed.1) The relationship between height and these three indices of weight was almost linear, when the data of extremely tall or short children were excluded.2) Increase of the ninth decile of weight (in Kilograms) per cm of height was remarkably larger as compared with increase of the mode and the first decile of weight per cm of height.3) Iecrease of the mode of weight per cm of height in children over fourth grade was much larger than that in children under third grade.4) The ninth decile of weight for a group of children who were extremely taller than the standard of their grade, was larger than that for groups of children of the same height in the higher grades.
