of  the  powdered  kernels  were  then  boiled  for  some  time  with  diluted 
hydrochloric  acid,  with  a  reflux  condenser,  to  invert  the  starch  which 
was  present.  The  reducing  sugar  which  resulted  from  the  inversion 
was  estimated  volumetrically  by  means  of  Fehling's  solution,  and 
yielded  3-89  per  cent.,  corresponding  to  3-5  per  cent,  of  starch.

The  fixed  oil  was  estimated  by  extraction  with  pure  anhydrous 
ether  in  a  Soxhlet  extraction  apparatus ;  five  determinations  were 
made,  weighing  the  residue  after  each  extraction  to  check  the 
results.  The  average  of  the  five  determinations  was  52*84  per  cent, 
of  fixed  oil.  This  was  in  the  dried  material,  and  is  equivalent  to 
30  65  per  cent,  in  the  average  nuts  in  the  unshelled  condition. 
The  oil  extracted  by  ether  was  dried  on  the  water-bath  for  several 
days,  to  a  constant  weight,  and  then  examined  for  comparison  with 
the  European  oil,  but  its  drying  properties  had  caused  it  to  assume 
characteristics  far  from  normal.    It  possessed  a  specific  gravity  of
