The purpose of this study was to investigate the changes of bony and soft tissue by the growth Each 50 boys and girls was studied aged 7 through 9 years old. The results were as follows ; 1. Thickness of soft tissue was increased by the growth and much more done in boys than in girls. 2. In the linear measurement of soft tissue change of A-A´ was most remakable. 3. Nose length was increased in both boys and grils. Remafkable change was observed in male aged 8 through 9 years old and in female gaed 7 through 8 years old. 4. In the linear measurement of bony tissue change, S-Pg, Go-Me, S-A, and S-N were increased in sequence. 5. Point-A and Pg in bony tissue grow aore downward direction than forward. 6. In the angular measurement, no significant change was obwerved.
