The author measured the weight of each rice grain divided into the two classes : the normal and the inferior, by the texture of grain, harvested from 155 experimental paddy fields distributed in Iwate Prefecture, in 1950, and made a ferquency distribution table (Table 3). Confliction came from the fact that the normal grains contain those which are lighter than the mean weight of the inferiors, and on the other hand, the inferiors contain those which are heavier than the mean weight of the normals, the frequency distributions of both being of wide ranges from 6 mg. to 24 mg. classes. The lower limit of grain weight of the upper 95% range in the normals was 16 mg. and the upper limit of the lower 95% range in the inferiors was 18 mg. About 16 mg. may be established as a limit weight between the normal and inferior rice grains.
