THE MILLING OF RICE.

extract, and crude fiber in the higher than in the lower or broken- 
rice grades of both the Honduras and the Japan types of rice. The 
protein figure for the milled rice of the Honduras type appears to 
be somewhat higher than that for the Japan type. This may be due 
to the greater length of the grain of the former and the consequent 
greater surface of the kernel, and therefore to the larger surface area 
of the protein-bearing aleurone layer. As previously stated, a con- 
siderable portion of this layer remains on the grain after milling.
