showed  8  74  per  cent,  of  tannin,  -64  per  cent,  of  glucose,  and  a  smaller 
amount  of  saccharose. 
The  rhizome  and  leaves  were  next  treated  with  water,  which 
removed  6*96  per  cent,  of  organic  solids  from  the  former,  and  8-44 
per  cent,  from  the  latter. 
Each  extract  was  made  to  measure  one  liter.  Both  were  neutral 
in  reaction.  That  of  the  leaves  possessed  a  darker  color  than  did 
the  one  from  the  rhizome.  They  contained  the  following  principles 
to  the  amount  given  : 
After  treatment  with  the  preceding  solvents,  one  liter  of  -2  per 
cent,  solution  of  sodium  hydrate  applied  to  each  of  the  materials 
extracted  4-31  per  cent,  of  organic  solids  from  the  rhizome,  and  4-82 
per  cent,  from  the  leaves.  Both  liquids  were  very  dark,  and  both 
contained  phlobaphene.  Mucilage  and  albuminoids  were  present  to 
the  extent  of  2- 80  per  cent,  in  the  rhizome  extract,  and  -72  percent, 
in  the  extract  of  the  leaves. 
After  washing  out  all  the  alkali  from  the  residues  of  the  leaves 
and  rhizome,  they  were  subjected  to  the  solvent  action  of  a  -2  per 
cent,  hydrochloric  acid  ;  the  latter  being  used  in  successive  portions 
until  one  liter  of  applied  liquid  was  obtained  in  each  case. 
The  liquids  were  yellow  in  both  cases,  that  of  the  rhizome  was 
found  to  contain  1-90  per  cent.,  and  that  of  the  leaves  180  per  cent, 
of  the  organic  matter  of  the  respective  parts  of  the  plant. 
1*20  per  cent,  of  pararabin  and  calcium  oxalate  were  found  in 
each  extract  by  making  a  portion  alkaline  with  ammonium  hydrate, 
mixing  it  with  four  volumes  of  alcohol,  allowing  the  liquid  to  stand 
for  twenty-four  hours,  collecting,  washing,  drying  and  weighing  the 
precipitated  substances.  A  little  over  50  per  cent,  of  the  leaves 
were  found  to  have  been  dissolved  by  the  above  solvents. 
That  portion  of  the  rhizome  which  remained  after  extraction  with 
solvents  was  treated  with  chlorine  in  the  presence  of  water.  The 
loss  in  weight  that  was  experienced  showed  that  815  per  cent,  of 
ligneous  matter  had  been  removed.  When  the  residue  from  the 
above  treatment  was  further  acted  upon  with  potassium  chlorate
