MENTIONED  that  I was 
not  aware  that  anything'  had 
been  done  toward  the  deter- 
mination of  the  composition 
of  Ceylon  soils  fertile  for  the 
paddy  crop  ; neither  do  I 
find  that  Ceylon-grown  rice 
grains  have  come  under  the 
investigation  oftheanalytical 
chemist.  It  is  therefore  necessary  to  look  else- 
where for  analytical  data.  The  following  analyses 
of  rice  may  be  quoted: —

Professor  O.  Kellner  gives  the  following  as 
the  composition  of  Japan  undressed  rice,  in  the 
dry  state.  There,  as  in  Ceylon,  there  are  many 
varieties  of  rice ; but  they  can  all  be  grouped 
under  two  classes,  the  marsh  rice  and  the 
mountain  rice,  the  former  being  cultivated  in 
irrigated  lields,  the  latter  on  dry  ground. 
Of  the  marsh  rice  there  are  two  principal  kinds, 
the  ordinary  and  the  glutinous  rice.  The  moisture 
in  the  marsh  rice  is  14-20  per  cent,  and  in  the 
mountain  rice  12  77  per  cent.  The  percentage 
composition  of  the  dry  matter  is  given  below.

Other  analyses  are  given  according  to  which 
marsh  rice  contains  9 -84  per  cent  of  protein 
matter,  and  1-571  per  cent  total  nitrogen,  while 
mountain  rice  contains  1 1 -27  and  1 -8  respectively. 
The  mountain  rice  is  thus  shewn  to  be  richer 
than  the  marsh  rice  both  in  protein  compounds 
and  in  starchy  matter,  but  not  in  mineral 
matter.

mineral  matter  in  rice: —
