Marriage custom in Miwa village, where 20.5% of 726 families were of consanguineous marriage, was further studied. Main findings are reported below:
1. Consanguineous marriage is most frequent in upper classes of the v illage.
2. Households containing more than one family are common among upper classes, but there is no trend that multi-familial household is derived from consanguineous marriage.
3. No significant differences were found between somatic measurements and intelligence of the consanguineous offspring and those of the non-consanguineous one.
4. It. was not proved in this village that defective traits of the offspring be related to consanguineous marriage.
5. Motivation of the consanguineous marriage in this village seems to consist of one or more factors of the following
(i) Interest in the family asset.
(ii) Narrowness of the social circles of the mother, key person of marriage-making.
(iii) Passive attitude of the son and daughter.
(iv) Racial trend of close internal cohesion of the population of the same decendance.

1. Somatic growth of Japanese females and accompanying change of various biometric ratios and proportions were studied in pupils of girls' high schools (aged 12-. 18 years) Group A, and employees of a silk factory (aged 12-21 years), Group B.
2. Items of measurements were (i) staure, (ii) weight, (iii) chest girth, (iv) waist girth, (v) girth of hips, (vi) breadth and (vii) depth of pelvis.
3. Indices computed included (i) Rohrer's index, (ii) relative weight, (iii) relative chest girth, (iv) relative waist girth, (v) relative hip girth, and (vi) pelvic index.
4. Growth and somatic proportions of Group A at the age of 16-18 correspond to those of Group B at the age of 18-19. In other words, Group A precedes Group B by about 1-2 years.
5. More irregularities exist in growth and somatic proportions among Group A than among Group B.
6. Final physique is in the average taller and more slender in Group A than in Group B. In all the age. levels investigated occurred this difference, which, however become more marked as the age avanced. It was suggested that Group A may belong to the leptosomatic type and Group B to the eurysomatic type.
7. Final absolute mass of the pelvis did not show any definite difference between these two Groups.
