548    MATERIA  MEDICA  OF  THE  INTERNATIONAL  EXHIBITION. 
of  a  pale  brown  color,  mixed  with  both  leaves  and  pods  of 
Alhagi  (?  Mauvorum  Tourn.)  It  therefore  differs  in  appear- 
ance from  the  Syrian  alhagi.inanna,  sent  by  Dr.  Gaillardot,  of 
Saida,  to  M.  Leon  Soubeiran,  which  the  latter  describes  as  com- 
pressed into  loaves  or  cakes. 
Cinchona  Bark — Neither  Peru,  Bolivia,  Ecuador,  nor  New 
Granada  have  contributed  any  series  of  the  Cinchona  barks 
which  are  produced  in  their  forests.  There  is,  however,  a  fine 
general  collection  exhibited  by  Messrs.  Howard  and  Sons,  of 
London,  and  illustrated  by  drawings  of  the  plants  as  well  as 
by  healthy  living  specimens  of  Cinchona  succirubra  Pav.,  0. 
micrantha  R.  et  P.,  C.  JJr aiming a 4Pav.,  (7.  nitida  R.  et  P., 
and  C.  peruviana  Howard.  Among  the  productions  of  the 
Dutch  colonies  are  specimens  of  genuine  Calisaya  bark  grown 
in  Java,  also  of  the  bark  of  C.  Fahudiana  Howard,  a  species 
of  very  little  medicinal  value. 
Balsam  of  Copaiba. — The  specimen  sent  from  Trinidad  is 
interesting  as  being  entirely  produced  by  one  species,  namely 
Oopaifera  officinalis  Jacq.,  a  tree  abundant  on  the  south  coast  of 
the  island.  Balsam  of  copaiba  is  not  at  present,  I  believe,  an 
article  of  export  from  Trinidad. 
Seeds  cf  Scaphium  :  Boa-tam-pauang.-—  In  a  recent  num- 
ber of  the  "Pharmaceutical  Journal,"  I  described  and  figured 
under  the  Chinese  name  Ta-hai-tsze,  a  drug  which  some  years 
ago  had  an  ephemeral  reputation  in  Paris  as  a  specific  in  diar- 
rhoea and  dysentery.  From  its  resemblance  to  the  fruits  of 
certain  species  of  Erioglossum  and  Nephelium,  I  conjectured  it 
might  belong  to  one  of  those  genera,  or  at  least  to  the  Order 
Sapindaceos.  In  May  last,  however,  M.  Decaisne  requested  me 
to  examine  whether  it  was  not  rather  the  seed  of  Scaphium,  a 
genus  of  Sterculiaceoe,  in  which  the  follicles  enclosing  the  seeds 
are  monospermous,  very  large  and  leaf-like,  and  open  long 
before  the  seed  attains  maturity.  The  correctness  of  M. 
Decaisne's  opinion  was  soon  confirmed  by  specimens  of  Sca- 
phium scaphigerum  Wall.,  contained  in  the  herbarium  of  the 
Royal  Gardens  of  Kew,  and  in  that  of  the  Linnean  Society, 
and  no  doubt  remained  that  the  seed  of  that  plant  constitutes 
the  drug  called  Ta-hai-tsze  by  the  Chinese,  and  Boa-tam-paijang
