was  treated  with  the  required  quantity  of  water  wliicli  formed  a  thick 
mucilage;  it  was  therefore  diluted  to  allow  of  straining,  and  bv  evap- 
oration brought  to  the  first  quantity  when  the  liquid  was  thinner  and 
permitted  filtration.  There  was  about  6'335  per  cent,  of  precipitate 
present,  which  was  regarded  as  albuminous  matter.  The  liquid  was 
then  treated  with  twice  its  quantity  of  95  per  cent,  alcohol,  which 
gave  a  precipitate  amounting  to  4*75  per  cent.  The  precipitate  from 
the  filtrate  by  lead  acetate  was  yellowish  brown  in  color.  This  was 
separated,  suspended  in  water  and  decouiposed  by  hydrogen  sulphide. 
The  filtrate  from  this  precipitation  was  evaporated  to  drive  off  hydro- 
gen sulphide,  this  liquid  then  gave  precipitates  with  barium  and  cal- 
cium hydrates,  and  a  green  color  with  ferric  chloride  ;  it  was  also 
precipitated  by  gelatin  solution,  by  which  means  it  was  estimated. 
The  tannin  present  amounted  to  3'9(3  per  cent. 
5.  Alkaline  Extraction. — The  powder  was  next  treated  with  a  0*2 
per  cent,  solution  of  sodium  hydrate.  The  dissolved  portion  amounted 
to  9'9  per  cent. 
6.  Acid  Maceration. — The  insoluble  portion  of  the  leaves  was  then 
treated  with  diluted  2  per  cent,  hydrochloric  acid.  The  extract 
amounted  to  about  6  per  cent. 
The  remaining,  undissolved  portion  was  bleached  and  weighed.  It 
amounted  to  42*6  per  cent.    This  was  regarded  as  lignin. 
Stem. — The  moisture  and  ash  of  the  stem,  as  in  the  case  of  the 
leaves,  were  estimated  from  the  same  portion  of  the  powder.  The 
moisture  amounted  to  10*16  per  cent,  ai  d  the  ash  to  r333  per  cent., 
the  small  amount  of  ash  being  probably  due  to  the  large  amount  of 
sclerenchyma. 
The  solubilities  of  the  ash  are  as  follows: 
Soluble  in  water  
Soluble  in  hydrochloric  acid 
Insoluble  in  either  
The  qualitative  analysis  gave  the  following  result:  Acids,  sulphuric 
and  hydrochloric;  Bases,  magnesium,  potassium,  sodium,  iron. 
1.  Petroleum  maceration. — The  powder  was  macerted  with  the 
necessary  quantity  of  petroleum,  the  portion  soluble  herein  amounted 
to  0'19  per  cent,  which  lost  nothing  on  heating  to  110°C.  The  resi- 
due was  soluble  in  ether,  tasteless,  unsaponifiable  by  cither  alcoholic  or 
aqueous  solution  of  potassium  hydrate.
