Wheat Middlings. 
The middlings form the inner coating of the wheat next the floury 
or starchy portion and contain portions of the germ and a larger 
per cent of nitrogen free extract, particularly starch, than either ship- 
stuff or bran, and a less per cent of fiber, while the per cent of 
albuminoids usually stands between that of shipstuff and bran. The 
analysis No. 43, already given, furnishes the data for the following at 4 
lbs. to the bushel of wheat:

Shipstuff. 
That part separated and known as shipstuff is a very thin layer 
next outside of the middlings, and contains the germ not found in the 
middlings or left as a part of the flour. The quantity produced, two 
pounds from a bushel of wheat, is very small and rarely kept separate 
from the bran. For analysis see preceding tables, No. 47.
