In 1966 and 1967 Agency of Industrial Science and Technology of Ministry ofInternational Trade and Industry undertook body measurements of 31,136 people (4-29 years of age) living in the 17 districts of the whole country. The purpose of thesemeasurements is to get basic data，so that proper garment sizes can be determined andthe standardization of size designations and proper JIS can be established. The present authors took charge of the Hiroshima District and measured 1,710 people of both sexes aged from 4 to 29. Part of the results of our measurements was reported in our previous papers，No.5 and No.6. We report here the results obtained from the measurements of 160 kindergarten boysand girls and also，a survey of the physical development of people from 4 to 29 yearsof age，with special reference to the size of parts of the body and the correlationbetween height，bust girth and the other items concerned. Here is a brief summary of the results: 1) The mean values obtained from the measurements of parts of the body remarkably increase with boys up to 16 and girls up to 14，but later the increase is less remarkable. As for girls，the remarkable growth is closely related to their first menses，which canbe seen from the fact that the most remarkable growth comes during the year before their first menses. 2) When mean values are compared between boys and girls，no big differences can be seen up to 13 years of age，but as they grow older，the differences become remarkable and boys from 22 to 29 are notably superior to girls of the same ages in the growth of every part of the body. 3) Large standard deviations are found in almost all the items with boys from 12 to 15，while girls between 9 to 12 show large standard deviations in length and width，and girls between 12 and 14，in girth length. 4) The rate value of each item to height is nearly the same，irrespective of age or sex，while the rate value of girth length to bust girth differs according to age and sex. 5) From Morrison's relative deviation broken lines with a standard line at the ages of 20 and 21，it is concluded that both boys and girls rapidly approach the standard line at the age of 10 and that this is more remarkable in the length item than in the girth item. Thus physical growth can be divided into three periods: boys，i) 4-10，ii) 10-16，iii) 16 and over. Girls: i) 4-10，ii) 10-14，iii) 14 and over. This meansthat both boys and girls between the ages of 4 and 10 gradually approach the standardline as they grow，and they rapidly approach the standard line at the ages between 10 and 16 or 10 and 14 with boys and girls respectively，then boys get to the standardline at 16 and girls，at 14. 6) A close correlation can be seen between height and length or weight，and between bust girth and the other girth length or weight.
