Table 56, Ferric Oxide. 



Soda, although it may not be essential to the growth of the 

 rice plant, is distributed in all its parts. The greatest quantity and 

 also the highest percentage arc found in the stems, as was to be 

 expected, for this ingredient is usually present in abundance in the 

 succulent portions of plants. The variations of the quantity of soda 

 thfioughout the plant's life, somewhat resemble those of potash. 



The percentage of lime in the entire plant decreases very 

 gradually in the course of the plant's life, but the leaves and stems 

 have increasing percentages. The highest percentages of lime arc 

 always found in the leaves, as was the case with nitrogen, which 

 was described before. Many investigators have proved that those 

 parts of a plant which are rich in chlorophyll contain a considerable 

 amount of lime. And this is also found to hold good as regards 

 the stems and leaves of the rice plant. The actual amount of lime
