gentea  is  about  half  the  size.  Both  yield  nutmegs  of  weak  odor; 
the  mace  is  more  scraggy  and  thin ;  likewise  of  poor  quality. 
Kamerun  lies  to  the  north  of  the  Congo  Free  State.  A  sickly 
gray  cheese  of  dika  bread  forms  their  staple  bread  fruit,  and  is  made 
largely  from  the  Irvingia  gabunensis. 
Strophanthus  Tholloni  is  shown  as  a  dark-brown  fleshy  pod  a  foot 
in  length.  The  seeds  are  very  much  flattened.  The  natives  make 
a  monkey- relish,  with  these  seeds  as  an  important  addition ;  the 
poor  apes,  a  terrible  pest  in  that  country,  monkey  no  more  after 
eating  a  small  amount  of  the  prepared  meal.  The  Strophanthus 
gratus  reminds  one  much  of  a  fat,  bulging  milkweed-pod ;  it  is 
smooth  and  of  a  pale-brown  tint.  This  is  much  used  to  prepare  an 
arrow  poison. 
Kamerun  copal  in  white  tears  of  clear  resin  down  to  the  unwashed 
brown  chunks  are  shown.  The  species  yielding  this  fossil  has  as 
yet  not  been  determined. 
Ceylon  cinnamon  quills,  cardamoms  and  many  spices  grow  in 
this  country  to  perfection. 
The  entry  port  for  German  Ost-Afrika  is  the  British  dependency, 
the  isle  and  city  of  Zanzibar.  Zanzibar  copal  (gum  anime)  is  of 
excellent  quality ;  the  various  grades  are  shown  in  good  samples ; 
this  copal  is  obtained  from  Trachylobium  verrucosum. 
Strophanthus  Eminh  Pax  et  Aschers  comes  in  light-gray  pods 
about  a  foot  in  length.  Strophanthus  grandiflorus  furnishes  very 
hairy  seeds,  broader  and  of  paler  tint  than  the  S.  hispidus.  In  looking 
through  the  glass  cases,  it  seems  to  us  that  the  S.  hispidus  distinguishes 
itself  from  all  the  other  seeds  of  these  varieties  by  being  of  uniform 
length,  about  ^  inch  long,  of  smooth  rounded  body  and  of  uniform 
deep-brown  tint.  The  more  highly  considered  5.  Komb'e  is  not  shown 
in  these  collections. 
On  trees  a  very  coarse  thread-like  lichen  grows  ;  this  has  a  some- 
what grayish  tint  when  dried.  This  is  the  Orcella  montagnei  ex- 
ported from  Zanzibar  in  quite  large  quantities  to  Europe,  where  it  is 
worked  up  for  a  kind  of  litmus  dye. 
In  concluding,  it  might  be  well  to  say  that  the  Germans  have  not 
spared  expense  to  make  all  their  exhibits  presentable  ;  elegant  show- 
cases are  as  essential  at  world  shows  as  in  sample-rooms  and  drug 
shops ;  the  general  impression  will  stick  in  the  mind  long  after  the 
exhibits  of  high  intrinsic  and  educational  value  are  forgotten.
