that the degree of corrosion was dependent on the grade 

 of milling was again distinctly brought to light. The general 

 wish for white, completely polished rice was in so far 

 welcome to the purveyors, as it relieved them from taking 

 precautionary measures for a somewhat long period of 

 storage. 



A good idea of the principle results with unpolished rice 

 can best be obtained from the following tables, which scarcely 

 demand any further illustration.

The experiments do not always turn out in this manner. 

 For instance, sometimes weevils were already to be found, 

 in uncoloured bottles, in three months' time. By another 

 experiment, there was at first no unfavourable proportion 

 to be observed in a light green bottle. In any case it 

 appeared that a normal exposure to light during storage 

 had the effect of delaying the destruction of the rice. On the 

 other hand it is to be remarked that a strong light had 

 more effect in producing a slightly rancid smell (and taste) 

 in unpolisheid rice than happened under the influence of 

 filtered rays of light.
