Abstract
The author reported herein the observation of the stature. sitting height and length of the legs in mountain villages by sex, age and town and country, and of the correlation between the stature and the length of the legs and between the stature and the sitting height.
1. The difference of height development by town and country became augmented with the rise of age, whose peak was found at the 6 th grade of elementary schools in case of schoolboys and at the 1 st grade of junior high schools in case of schoolgirls, then traced a decrease. The difference of the sitting height and the length of the legs by town and country showed a trend toward a gradual decrease with the advancement of age. In this case, the peak of sitting height fell on the 2 nd grade of junior high schools in case of schoolboys and on the 6 th grade of elementary schools in case of schoolgirls, while the peak of length of the legs was found at the 6 th grade of elementary schools in case of schoolboys and at the 1 st grade of junior high schools in case of schoolgirls.
2. The cause for such a difference of the height development by town and country may be attributed chiefly to the difference of siiting height at the lower grades of elementary schools and the difference of length of the legs after the higher gradei of elementary schools in case of schoolboys. On the other hand, in case of schoolgirls, it may be ascribed to the difference of length of the legs at the begining, then the difference of length of the legs and siiting height, and chiefly to the diefference of length of the legs at the higher grades of junior high schools.
3. The correlative value between the stature and the length of the legs was much higher in both sexes, the value of which was greater in the urban district than mountain villages.
4. The curve of correlative coefficient values by age between the stature and the length of the legs showed that the manifestation age of the peak in both the urban district and mountain villages fell approximately on the 6 th grade of elementary schools and the 1 st grade of junior high schools, where the difference of stature by town and country revealed strongly in the classes of this age.
The manifestation of the peak of stature and sitting height was observed at younger ages in schoolgirls than schoolboys
