The results in Table 12 clearly demonstrate that the middlings 

 stocks are much cleaner than stocks obtained from the break rolls. 

 The first five middlings stocks average low in the total offal count, 

 while the stocks from the sixth to ninth middlings, inclusive, average 

 appreciably higher. In other words, the more thorough the purifi- 

 cation process, the lower will be the offal count. 



For the purpose of showing the offal count on the stocks which pass 

 into some so-called patent flours, three different sets of mill streams
