 wheat into thin sections, and examine it with a glass of 

 greatly magnifying power, the various parts will appear

 The section repre- 

 sented by I reveals

 than either of the 

 others, which is so

 even by the aid of 

 a good glass. The part of the illustration at d, repre-

 cipally of gluten. " These four layers constitute the 

 bran. The gluten in the cells, <#, appears to be a faint 

 yellowish substance, very small grained, and oily to the 

 touch and smell. The cells in which the gluten is
