Table III. 



In Table IIT. , we give the mean values and the difference of 

 the Japan Sea and Pacific sides of the NE, Central and SW parts 

 of Japan respectively. Referring to the latter, we may remark 

 several interesting facts. Firstly, the mean values of the both 

 sides, are greatest in the Middle part III-IV, during the colder 

 months Oct. -Feb., while it is so in the SW part during the warmer 

 months, Mar. -July and Sept. While during the colder months, 

 the NE and SW regions have nearly same amounts of precipitation, 

 contrasted w^ith the large amount in the Middle Japan, the amount 

 of precipitation during the warmer season continously falls off from 

 the SW towards the NE districts. Secondly, the difference, Japan 

 Sea side minus Pacific side show quite parallel course, but the 

 mean value successively falls off from the Northern part to the 

 Southern. Thirdly, among different possible combinations of cases, 

 I>II, III > IV, V>VI occurs in January and December, 



occurs in February, jMarch, October 

 and November, 



occurs in April, May, June, and 

 September, 



occurs in July and August. 



I>II, III>IV, V<VI 

 I<II, III<IV, V<VI 



I>II, III<IV, V<VI 



But the remaining two cases: 



I<II, 1II<IV, V>VI, and I<II, III>IV, V>VI 

 do not occur actually.
