plentiful  stock  of  healthy  animals  carefully  protected  in  Hy-proof 
cages  at  hand,  and  to  inoculate  such  immediately  on  the  death  of  the 
game,  or  to  convey  citrated  blood  back  with  as  little  delay  as  possible. 
This  would  have  to  be  carried  out  in  both  clean  (fly-free)  and  tsetse 
infested  districts  ;  and  it  is  one  of  the  first  problems  in  the  etiolog)' 
of  trypanosomiasis  that  should  be  undertaken.  In  Northern 
Rhodesia,  and  elsewhere,  considerable  difficulties  will  be  experienced 
owing  to  the  non-pathogenicity  of  certain  endemic  trypanosomes 
towaids  the  oidinary  laboratory  animals ;  it  would  appear  almost 
imperative,  therefore,  that  sheep  and  goats  should  be  employed. 
In  addition  to  game,  wherever  possible  all  small  animals  such  as 
mice,  rats,  moles,  bats,  snakes,  lizards,  birds,  as  well  as  crocodiles 
were  examined.  Trypanosomes  were  seen  only  in  a  species  of  bat ; 
no  blood  parasites  w’ere  observed  in  the  crocodile. 
The  following  is  a  list  of  the  game  examined.  It  has  not  been 
deemed  necessary  to  publish  the  localities  wherein  each  was  shot ; 
it  is  enough  to  say  that  they  were  obtained  in  both  clean  and  fly- 
infested  districts:  —
