The total offal count on these samples was consistently higher in 
most cases than the results obtained on samples ground from mid- 
dlings stock only. The addition of break flour stocks appeared to 
have a marked effect upon their quality with respect to the offal 
count. The bran particles ranged in count from IS to 133, with an 
average of 48. The hair count ranged from 12 to 45, with an average 
of 26. The total offal count varied from 31 to 162, with an average 
of 74. 
GEXESAL CONCLUSIONS OX PATENT FLOTTBS. 
1. The com m ercial grades of so-called patent flours ranged from 
35 to 90 per cent. These percentage figures apparently were in- 
tended to indicate that a certain percentage of the total flour content 
of the wheat kernel passed into this grade, the remainder being 
employed in other grades. 
2. The average total offal count obtained on all commercial patent 
flours examined was 57. 
3. Patent flours showed a marked variation in the total offal count 
obtained on different samples from various mills. 
4. The limitations and the average counts on bran particles and 
haii-s have been briefly summarized in Table 21.
