hours ;  the  insoluble  matter  was  again  dried  and  weighed  and  the 
loss  calculated  as  lignin.  The  residue  was  then  incinerated  and  the 
loss  estimated  as  cellulose. 
Moisture  and  Ash. — The  moisture  was  obtained  by  drying  two 
grammes  of  the  powdered  beans  at  100°  C,  in  an  air-bath  to  a 
constant  weight.  The  residue  was  incinerated,  which,  when 
weighed,  gave  the  ash.  A  qualitative  examination  of  the  ashes 
gave  the  following  general  constituents : 
Potassium. 
Magnesium. 
Calcium. 
Sodium. 
Silica. 
Phosphates. 
Sulphates,  trace. 
Chlorides,  trace. 
Carbonates,  trace. 
Iron  was  found  in  varying  quantities  in  all  except  the  Tobasco
