Rice  feeding  meal  mentioned  in  the  above  table 
consists  chiefly  of  the  external  layers  of  rice 
which  are  separated  in  dressing.  It  will  be 
observed  that  it  is  much  richer  in  nitrogenous 
substance,  in  fat  and  in  mineral  matter  than  is 
the  whole  grain.  In  the  matter  of  fat  it  stands 
higher  than  all  the  other  feeding  stuffs  quoted 
in  the  following  table  of  parts  and  products  of

substance.

cereal  grains  from  Mr.  Warrington’s  article  on 
“Cereals”  in  Thorpe's  Dictionary  of  Applied 
Chemistry.  There  is  also  a good  percentage  of 
nitrogenous  matter,  and  it  is  richest  of  all  in 
mineral  matter,  with  its  8 to  10  per  cent  of  ash, 
of  which  43  per  cent  is  phosphoric  acid.  The 
proportion  of  ash  in  various  husks  is,  of  course, 
larger,  but  it  consists  mainly  of  silica.
