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
