by  a  chain  of  circumstances  which  have  necessitated  considerable 
changes  in  the  original  plan  and  in  the  route  to  be  followed.  One  of  the 
causes  for  the  delay,  which  has  given  a  great  deal  of  concern  to  those 
interested,  was  the  illness  of  the  Director,  Dr.  H.  H.  Rusby,  Dean 
of  the  College  of  Pharmacy  of  Columbia  University.  Dr.  Rusby 
has  been  suffering  from  a  severe  and  prolonged  attack  of  pleuro- 
pneumonia, which  struck  him  down  very  suddenly  in  the  midst  of 
active  preparations  for  his  trip.  His  many  friends  in  the  medical 
and  pharmaceutical  professions  and  among  botanists  will  be  pleased 
to  learn  that  he  is  now  well  on  the  road  to  complete  recovery. 
The  enforced  delay  has  not  been  without  benefit.  From  one 
point  of  view  it  has  been  of  actual  advantage,  in  that  ample  time 
was  afforded  for  the  elaboration  of  plans  and  preparations  in  the 
greatest  possible  detail.  It  has  also  resulted  in  the  enlargement  of 
the  scope  of  the  work  to  be  undertaken  and  in  the  personnel  of  the 
party. 
Membership  in  the  party  as  now  constituted,  includes  Dr.  H.  H. 
Rusby,  as  Director,  who  will  be  accompanied  by  a  secretary,  per- 
sonal assistant  and  taxidermist  in  the  person  of  George  S.  McCarty, 
a  young  man  of  sportsman-like  qualities  and  training,  from  a  well- 
known  family  of  Woodbury,  N.  J. 
Dr.  Rusby  will  also  be  accompanied  by  Dr.  Wm.  M.  Mann,  an 
Entomologist  of  the  Bureau  of  Entomology,  U.  S.  Department  of 
Agriculture,  and  Honorary  Custodian  in  the  Division  of  Insects, 
U.  S.  National  Museum.  Dr.  Mann  is  an  explorer  and  collector  of 
wide  experience  in  tropical  travel. 
E.  N.  Pearson  joins  the  party  as  Ichthyologist,  representing  Dr. 
C.  H.  Eigenmann,  of  the  University  of  Indiana,  and  Dr.  A.  G.  Ruth- 
ven,  of  the  University  of  Minnesota. 
The  botanical  work  of  the  expedition  will  be  greatly  increased 
by  the  addition  to  the  party  of  Dr.  Orland  E.  White,  of  the  Brook- 
lyn Botanic  Garden,  who  goes  as  representative  of  the  Brooklyn 
Botanic  Garden  and  of  the  Bussey  Institution  of  Harvard  Uni- 
versity. 
He  will  devote  his  energies  to  the  collection  of  orchids  for  Dr. 
Ames,  and  to  the  study  of  the  economic  botany  of  the  regions  cov- 
ered. 
The  complete  study  of  the  medicinal  products  will  occupy  the 
attention  of  many  specialists.    Dr.  Rusby  will  himself  undertake
