74 ' COMMERCIAL FEEDING STUFFS. 



Of the wheat products there are three, designated in Table 2 as 

 W. P. No. 1, W. P. No. 2, and W. P. No. 3. These abbreviations have 

 the following significance : 



Wheat product No. 1 : Composed mostly of the outer seed coats 

 (pericarp) of the wheat kernel. In addition there are small amounts 

 of the other seed coats, aleuron layer, endosperm (starchy portions), 

 and germ. 



Wheat product No.. 2 : Composed of relatively less of the pericarp 

 and of a greater portion of the inner coats, aleuron layer, germ, and a 

 considerably larger amount of the endosperm in more or less broken 

 condition. The portions of epicarp present are usually of smaller 

 size than those of wheat product No. 1. 



Wheat product No. 3 : Composed mostly of the inner seed coats, 

 aleuron layer, and starchy portions with a small amount of the 

 epicarp, and sometimes small amounts of germ. The most important 

 difference between this and product No. 2 is that there is a larger 

 amount of endospermous material.
