It has already been _known that the fall in the percentage of consanguineous marriage and the enlargement of the range of mating is in close correlation. The author made investigations on the range of mating in Kawamata town which is located in the northern part of Fukushima prefecture. The results obtained were as follows; 1. Marriages within blood in Ojima and Otsunaki districts of the village were 22.97% and 11.29% respectively, while in Yamakiya district the perccntage was so high as 47.31% indicating a remarkable narrowness of the range of mating in the district. 2. In Ojima and Otsunaki districts the range of mating tended to be enlarged according to younger years of age but such a tendency was not observed in Yamakiya district. 3. The range of mating of consanguineous marriage was far narrower than that of non-consanguineous marriage. The above-mentioned resnits were wholly concordant with the results of the study of consanguineous marriage in the same district which revealed the extremely high percentage of consauguineou marriage in Yamakiya district in comparison with other districts and the absence of the decreasing tendency of the percentage in proportion to younger years of age in the district. These facts may be considered to indicate the importance of enlargement of the range of mating for the purpose of the reduction of consanguineous marriage.
