CHEMICAL ANALYSES OF SAMPLES OF IMPORTED RICE. 



Chemical analyses of single samples considered characteristic of the 

 various imported rice types were made in the Bureau of Chemistry. 

 The determinations made on each sample covered moisture, ash, ether 

 extract, protein, and crude fiber. The results of these analyses are 

 given in Table III.
