In literature of physical development has not been clearly determined, whether the aspect of individual physical growth in the first grade of the elementary school will undergo any changes in its process in the following years, or will maintain the same or similar condition. The present study trys to solve these problems. The data were attained from 370 representative samples of urban girls who were measured at stature, weight, and chest girth anually from the 7 th to 17 th year of their life. The summary is as following. I) Patterning The curve lines of the individual growth were classified, for convenience, into 12 patterns in stature and 16 patterns in weight. It appeared, that a few cases both in stature and weight showed the same pattern as the standard curve line. Amoung 12 patterns in stature and 16 patterns in weight, those which run in parallel with the standard curve line are fewer than those which do not. As regards the latter patterns, the following facts were found by applying the patterns to the four kinds of tendecies of increase and decrease term in physical growth process. As for stature, there were many cases in which the increment was shown since post child period and few cases in which the decrement was shown since pre-adolesence. As for weight, there was not found any significant tendencies. II) Prediction In stature, the correlation coefficent between 7 and 17 years is. 61, and between 12 and 17 years is. 63. In weight the correlation coefficent between 7 and 17 years is. 46, and between 12 and 17years is. 55. In chest girth, the correlation coefficent between 7 and 17 years is. 22, and between 12 and 17 years. 47.
