defined  by  the  late  Professor  Balfour  ("  Pharmacographia,"  2d  ed., 
p.  370).    The  six  plants  when  dried  in  the  sun  afforded : 
Grams. 
Root  21 
Stem   8 
Leaves   4'8 
These  were  reduced  to  fine  powder,  and  a  sample  of  each  was 
examined  separately,  according  to  the  same  process.  The  powder 
was  exhausted  with  warm  alcohol,  the  percolate  evaporated  to  dry- 
ness on  a  water  bath,  water  added  to  the  dried  extract  and  acidu- 
lated with  diluted  sulphuric  acid.  After  filtering  and  washing  with 
water,  the  clear  liquid  was  treated  with  some  freshly  prepared 
Mayer's  solution,  1  cc.  of  which  corresponds  with  0  0189  gram  of 
emetine,  until  a  precipitate  ceased  to  be  formed.  The  results  of 
this  analysis  were  as  follows: 
Root  contained  179  per  cent,  of  alkaloid. 
Stems       "  ■  1-13 
Leaves      "       1*45       "        "  " 
The  alkaloid  was  examined  qualitatively ;  that  separated  from 
the  stems  and  leaves  had  the  same  appearance  and  characters  as 
that  from  the  root,  and  it  was  doubtless  emetine.  Herbaceous 
plants  containing  an  alkaloid,  almost  invariably  yield  the  same 
alkaloid  in  different  parts  of  the  plant,  but  in  trees  and  shrubs  dif- 
ferent alkaloids  often  occupy  different  portions  of  the  same  plant. 
It  is  of  interest  to  know  that  the  leaves  and  stems  of  the  true 
ipecacuanha  contain  a  good  proportion  of  emetine,  but  they  are  not 
likely  to  displace  the  root  from  its  position  in  the  Pharmacopoeias 
and  in  commerce. — Phar.  Jour,  and  Trans.,  Jan.  23,  1892,  p.  591. 
ALKALOID  FROM  CHRYSANTHEMUM  FLOWERS.1 
By  F.  Marino  Zuco. 
The  author  has  previously  extracted  from  chrysanthemum  flow- 
ers a  new  cholesterol,  a  glucoside,  and  an  alkaloid.  (See  Amer. 
Jour.  Phar.,  1890,  p.  579).  The  latter  is  prepared  in  quantity  by 
boiling  about  10  kilos,  of  the  flowers  in  distilled  water  (3  parts)  for 
two  or  three  hours,  filtering  through  cloth,  pressing  the  residue  and 
treating  it  again  in  the  same  manner.    The  extracts  are  evaporated
