As  presented  above  in  Table  III,  where  the  root  is  also  con- 
sidered a  part  of  the  whole,  the  leaf  represents  about  40  per  cent, 
of  the  total  portion  of  the  plant. 
The  samples  of  stramonium  as  presented  for  analysis  consisted  of 
from  40  to  100  gms.  of  material  in  each  sample,  and  in  every  case 
the  entire  amount  was  carefully  ground.  From  this  ground  ma- 
terial the  sample  for  the  determination  was  taken.
