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.
