Five young paddy rice plants {-'ar. ScJcitori) equal in size were 

 trans-planted in each pot on July 5, 1905, and kept in paddy state. The 

 plants in pot (A) was normal while those in pot (B) and (C), showed 

 a yellowish green color in the first period of growth and much foam 

 gathered on the surface of the soil especially in pot (C). After two weeks, 

 however, the plants in pot (B) and (C) again acquired a green color but not 

 the deep green as observed in pot (A). 



The following table shows the result of observations on July 25 and on
