PREFACE 
The  members  of  this  expedition*  desire  to  offer  on  behalf  of  this 
Tropical  School,  and  indeed  of  all  interested  in  trypanosomiasis,  their 
grateful  thanks  to  the  British  South  Africa  Company,  the  adminis¬ 
trators  of  Rhodesia,  for  the  enlightened  way  in  which  they  undertook 
this  survey  of  that  territory,  and  to  Sir  Alfred  Sharpe,  K.C.M.G.,  the 
Governor  of  Nyasaland,  for  his  ready  and  sympathetic  assistance  on 
questions  relating  to  the  country  more  immediately  under  his  control. 
We  wish  especially  to  thank  the  local  Governments  of  North- 
Eastern  and  North-Western  Rhodesia  for  the  way  in  which  they 
catered  for  our  many  requirements,  and  to  the  Administrators,  the 
late  Mr.  Robert  Codrington  and  Mr.  L.  A.  Wallace,  for  the  personal 
interest  they  have  taken  in  the  work  and  the  encouragement  and  help 
they  always  gave.  It  is  due  to  their  generous  reception  that  it  was 
possible  for  us  to  endeavour  to  carry  out  our  instructions. 
All  Europeans  with  whom  we  came  in  contact,  must  be  enumerated, 
were  each  one  to  whom  we  are  indebted  to  receive  mention,  but  our 
special  thanks  are  due  to  the  Principal  Medical  Officers,  Drs.  J.  C. 
Spillane  at  Fort  Jameson  and  H.  Hearsey  at  Zomba,  and  to  Mr. 
A.  J.  Lane,  the  Veterinary  Officer  of  Northern  Rhodesia.  To  the 
following  stock-owners,  who  gave  us  notable  assistance,  we  would 
offer  our  hearty  gratitude.- — Messrs.  J.  F.  F.  Johnson,  F.  C.  Miles, 
J.  B.  Yule  and  Mr.  B.  Turner,  of  the  London  Missionary  Society  at 
Kambole ;  and  also  to  the  following  officials  who  gave  special 
assistance :  — Messrs.  H.  C.  Marshall  of  Abercorn,  and  R.  Young  of 
Chinsali.  Lastly  we  must  again  mention  Dr.  Arnold  Theiler,  C.M.G., 
Pretoria,  to  whom  we  are  indebted  for  many  guinea-pigs  and  rats 
without  which  our  trypanosome  strains  could  not  have  been  main¬ 
tained,  and  who  has  most  kindly  undertaken  charge  of  those  we 
carried  back  from  Lake  Tanganyika.
