i Omitted from summary, as ground hulls probably had been added to sample. 



2 Omitted from summary, as mill was milling abnormal, damaged rice. 



3 Omitted from summary, as mill was running on a mixed lot of broken rice. 



* Sample was taken from a lot of bran ready for the market. Exact history of bran unknown.

1 Polish from a second brush. 



2 The figures for ether extract in these samples are not representative and were not used in obtaining 

 minimum percentage. 



3 These two polishes are mixed before being put upon the market. 



4 In this mill the rice is scoured by three pearling cones before it is sent to the brush. 

 & Low-grade rice that was heavily milled: polish abnormal. 



6 Rem ill in g mixed lot of broken rice; polish abnormal.
