392  Report  on  Samples  of  Ipecacuanha.  {AmAug.%893arm' 
(7)  Therefore,  100  parts  of  this  No.  2  sample  of  so-called  ipecac- 
uanha yield  1*975  parts  of  emetine;  for  1-327  plus  0  648  equal  1-975. 
(8)  Further,  a  direct  determination  of  the  alkaloid  in  this  No.  2 
sample  gave  me  1-950  per  cent,  of  emetine. 
(9)  The  figures  in  paragraph  5  show  that  the  official  ipecac- 
uanha in  this  No.  2  sample  contains  2  020  per  cent,  of  emetine. 
(10)  The  figures  in  paragraph  6  show  that  the  ipecacuanha  stems 
in  this  No.  2  sample  contain  1-890  per  cent,  of  emetine. 
(11)  The  moisture  in  the  official  ipecacuanha  of  the  sample 
amounts  to  99  per  cent.;  the  moisture  in  the  stems  to  8-1  percent.; 
in  the  whole  sample,  9-3  per  cent. 
The  "  No.  59  "  Sample. 
(13)  I  find  this  to  consist  of  62-6  per  cent,  of  official  ipecacuanha 
and  34-4  per  cent,  of  ipecacuanha  stems. 
(14)  The  62-6  parts  of  official  ipecacuanha  contain  1-252  parts 
of  the  alkaloidal  substance  known  as  emetine. 
(15)  The  34-4  parts  of  ipecacuanha  stems  contain  0  546  parts  of 
similar  emetine. 
(16)  Therefore,  100  parts  of  this  No.  59  sample  of  so-called 
ipecacuanha  yield  1-798  parts  of  emetine;  for  1-252  plus  0-546 
equal  1-798. 
(17)  Further,  a  direct  determination  of  the  alkaloid  in  this  No. 
59  sample  gave  me  1-820  per  cent,  of  emetine. 
(18)  The  figures  in  paragraph  14  show  that  the  official  ipeca- 
cuanha in  this  No.  59  sample  contains  2  000  per  cent,  of  emetine. 
(19)  ,  The  figures  in  paragraph  15  show  that  the  ipecacuanha  stems 
in  this  No.  59  sample  contain  1-46  per  cent,  of  emetine. 
(20)  The  moisture  in  the  official  ipecacuanha  of  the  sample  is 
practically  10  per  cent.;  in  the  stems  8  per  cent.;  in  the  whole 
sample,  9-3  per  cent. 
Remarks. 
(21)  These  two  samples  of  so-called  ipecacuanha  contain,  in 
round  figures,  two-thirds  only  of  official  ipecacuanha  and  one-third 
of  ipecacuanha  stems. 
(22)  By  official  ipecacuanha  I  mean  that  which  alone  is  recog- 
nized by  the  compilers  of  the  British  Pharmacopoeia,  and,  therefore, 
that  which  can  alone  be  used  legally,  under  the  Medical  Acts  in  the 
official  "  Preparations  "  of  ipecacuanha,  namely,  true  roots.
