MICROSCOPICAL, EXAMINATION OF FLOUR. 



23 



The bran particle count varied from 33 to 183, with an average of 

 68, while the hair count varied from 18 to 58, with an average of 34. 

 The total offal count varied from 57 to 201, with an average of 100. 

 The average total offal count obtained for the straight flours was 111, 

 as against 57 for patent flours. 



MILL STREAMS EMPLO"5f*EB IN THE MANUFACTURE OP CERTAIN STRAIGHT FLOURS. 



Data were obtained on the mill streams employed in the manu- 

 facture of certain straight flours, and these streams were examined 

 for their offal content for the purpose of illustrating the quality of 

 the material sometimes used in making up such flours. The results 

 are given in Tables 25, 26, and 27.
