    From the previous investigation and others we got an idea that the logarithm of the true air speed can be expressed in an algebraic function of the third degree with respect to the logarithm of the rotating speed of anemometer-cup, that is, logV=α+βlogμ+γ(logμ)2+δ(logμ)3, which has an inflexion point.
    Taking the Kew Standard nine-inch-cup anemometer as an example, we tried to express our idea substantially, and obtained a fair result, which has small error.
    From this formula we can derive another one for the variable factor of the anemometer. It is worth to notice that the latter expression has a maximum and a minimum.

    The seasonal variations on the amount of O2, CO2, and pH in the water of Ohori were examined for a year during April 1932 and the end of March 1933, concerning the diurnal changes of them produced by the photosynthetic reaction of aquatic plants. It is the remarkable characteristic of the water of Ohori that the dissolved O2 is supersaturated in the almost all seasons, especially in the late spring time and the summer the saturation percentage of O2 rises to 18% and the value of pH is alkali in the whole year. The feature of the seasonal fluctuation of the aquatic plants may be showed by the formula, viz. d/S/S0, where d is the amplitude of the diurnal change of O2, S the total amount of solar radiation in a day and S0 the calculated amount of the undisturbed radiation.

    1. According to the observation at about 40 stations in Manchuria, the average annual rainfall amount shows no more. than one half to one third of that in Nippon proper.
    2. The geographical distribution of annual rainfall of the east mountainous region shows about 900mm. and gradually decreasing to the west and about 300mm. in the west of the Hingan range.
    3. The distribution of rainfall in the middle plain region occurs chiefly on the rain due to mountain barriers towards the east by the southwest monscon in summer and is of comparatively rare occurrence by the rain due to cyclones.
    4. The prevailing direction of rain-bearing wind occurs north in April, east-northeast in May, south-southwest in four months from June to September. The prevailing direction of the total amount of rainfall occurs west-southwest in April, east-north-east in May, south in summer four months. The average amount of rainfall divided by the number of wind direction occurs the maximum value east-northeast in April, southwest in May, south-southeast in summer four months.
    5. The daily maximum amount of rainfall observed 209.3mm. at Yingkou in the south, 157.0mm. at Anta in the north. In the south the daily maximum amount of rainfall is decreasing accordingly to the distance from the coast. In the north there are heavy rainfall region about 150mm. daily in the valleys of the rivers Nonni and Sungari. Another places measured the daily amount under 200mm. in the south and 100mm. in the north.
    6. In the south the maximum daily amount of rainfall caused by the rain due to the typhoon cyclone and in the north by the rain due to the ascending current depression with local thunderstorm.
    7. The percentage the daily maximum amount divided by the average annual total rainfall the larger places are over 30, the average is about 20, the smallest is 13.
