This,  however,  only  applies  to  the  above-mentioned  kinds,  and 
does  not  affect  the  supply  derived  from  Landolphia  florida,  and  the 
other  species  of  Carpodinus.  These  latter  plants  were  found  in  fairly 
open  dry  ground,  at  from  I, OOO  to  3,500  feet,  and  are  probably  very 
abundant  everywhere.  The  rubber  yielded  by  them  is  neither  so 
good  nor  so  abundant  as  that  from  the  above-mentioned  kinds, 
though  probably  it  could  be  immensely  improved  by  better  means 
of  extraction.  With  regard  to  the  rubber  from  trees,  I  only  found 
Ficus  Vogelii once  in  the  Niger  drainage  area  ;  this  is  the  kind  found 
at  Bassa  and  lower  down  the  coast.  There  are  about  thirty-nine 
specimens  of  Ficus  sorts  in  my  collection,  and  it  is  of  course  possible 
that  several  of  these  yield  rubber,  but  the  only  other  species  of 
which  I  heard  this  is  a  new  species.  On  the  whole,  the  supply 
existing  in  the  country  we  traversed  cannot  be  considered  as  of  great 
importance. —  Colonial  Report ;  from  Pharm.  Jour,  and  Trans.,  July,

REPORT  OF  TWO  SAMPLES  OF  "  IPECACUANHA."1 
By  Professor  John  Attfield,  Ph.D.,  F.R.S. 
(1)  Each  sample  was  duly  sealed  in  red  wax,  impressed  "  London 
and  India  Docks  Joint  Committee." 
(2)  One  sample  was  labelled  as  follows : — "  London  and  India 
Docks  Joint  Committee.  Ex  Tamarind  Rail.  93  / 44.7.  J.  F.  M. 
No.  2.  1  Bale.  2  lbs.  sample  Ipecacuanha.  Crutched  Friars 
Warehouse.  29'5-'93." 
(3)  The  other  sample  was  thus  labelled : — "  London  and  India 
Docks  Joint  Committee.    Ex   Tagus  and  Rail.    93  /333. 
No.  59.  1  Bale.  2  lbs.  sample  Ipecacuanha.  Crutched  Friars 
Warehouse.  2g-$-'93." 
The  «  No.  2  "  Sample. 
(4)  I  find  this  to  consist  of  65-7  per  cent,  of  official  ipecacuanha, 
and  34-3  per  cent,  of  ipecacuanha  stems. 
(5)  The  65-7  parts  of  official  ipecacuanha  contain  1-327  parts  of 
the  alkaloidal  substance  known  as  emetine. 
(6)  The  34-3  parts  of  ipecacuanha  stems  contain  0  648  parts  of 
similar  emetine.
