    太平洋岸を温帯性低気圧が通過する代表的な場合14回をえらび1回ごとの降水量分布を調べた.得られた結果は下記の通りである.
    (i) 関東平野部では降水量は低気圧中心の経路からの距離と直線的な関係で減少する.
    (ii) その減少率は全国を通じてみると絶対量が多い時に大である.
    (iii) 関東周辺の山地におけるある地点の実測値と,その地点が平野であつたと仮定して求められる理論値との差を山地なるがゆえに偏差した値とし,その分布図を書くと北部・西部型と北部・丹沢型の2つにわかれる.
    (iv) 偏差値の各地点ごとの全国の平均値の分布図は第5図の通りである.
    (v) この値を海抜高度との直線関係がより高い有意水準で求められるように地域区分した(第5図).
    (vi) 高度が100m高くなるにつれて増加する降水量は平均的にいつて,栃木県南東向斜面で3mm, 長野県(長野・飯山地方)で3mm, 丹沢の背面で2.5mm, 群馬県の南東向斜面で2mm,栃木・群馬の雨かげ地域で1mm,関東西部山地ではそれ以下である.

    The characteristics of the migration caused by marriage in 3 cities and 5 towns-of Kagawa Prefecture in 1949 may be summarized as follows
    1. Migration rate per 1, 000 inhabitants is 19.0, 93% of which is occupi-ed by women, and 11.1.% by divorcees.
    2. The greater the population of a city, the higher the rate of influx to efflux, and vice versa. The relation between the population of a city and the rate of migrators is indicated by a curved line.
    3. The greater the population of a city, the higher the rate of intra-city migration, and the relation between the population of a city and the number of intra-city z xmigration is also shown by a curved line.
    4. The number of intra-prefecture irrigation is greater than that of the migration between Kagawa and other prefectures, and in this case the, infl-ux people into cities outnumber the efflux people from the cities. The sphere of intermarriage is defined to a limited area surrounding the cities which respectively. forms an elliptical area with major axis in N-S direction. The greater the population of the city, the larger the area of the sphere of intermarriage, and the relation between them is indicated by a straight line.
    5. In case of the migration between the cities of Kagawa prefecture and other prefectures, efflux people from the cities are more numerous than in-flux people into the cities. The sphere of intermarriage of this case cover Osaka-Kobe area, Setouchi, Shikoku, and the northern parts of Kyushu etc.
    6. Judging from the rates, the migration caused by marriage was made in the following order: (1) within native cities and towns, (2) within the prefecture, (3) between Kagawa and other prefectures. Generally speak-ing, in the cases of (2) and (90), the cities and towns of Kagawa prefecture had influx people from the farm villages within the prefecture and efflux people in the cities and towns in other prefectures.
    7. The migration caused by marriage took place mainly in April, Janu-ary, October, May, December and February, and most infrequent in June, July, August and. September. But the migration caused by divoce took place mainly in August, and infrequent in November. It is clear that the mig-ration have a close connection with the season.
