particular  attention  was  paid  to  these  cases,  and  we  purchased  a  sick 
animal  in  order  to  obtain  a  post-mortem.  The  only  lesion  which 
could  be  demonstrated  was  the  presence  of  D.  hefaticmn  in  small 
numbeis.  Saving  for  the  losses  this  year,  native  cattle  throughout 
the  division  have  done  well,  and  tsetse  {Gl.  palpalis)  only  exist  on 
the  shores  of  Tanganyika  and  {Gl.  morsitmis)  to  the  West  of  the 
division.  Cattle  are  kept  at  the  three  stations  of  the  London 
Missionary  Society,  Niamkolo,  Kambole  and  Kawinibi.  At  the  first- 
named  there  is  no  history  of  disease  and  our  examinations  were 
negative.  At  Kawimbi  the  cattle  appear  to  have  been  affected  by 
the  same  disease  which  occurred  in  the  native  cattle  around  ;  at  our 
visit  no  trypanosomes  could  be  found.  Kambole  is  situated  within 
a  few  miles  of  Gl.  morsiians,  though  until  1905  cattle  are  reported  to 
have  done  exceedingly  well.  In  that  year  twenty  head  died,  and 
since  then  the  loss  has  been  from  four  to  six  per  annum.  We  found 
six  animals  in  the  herd  of  sixteen  infected ;  their  histories,  so  far  as 
records  are  available,  and  the  observations  on  the  trypanosomes  will 
be  given  later.  In  the  Abercorn  district  there  are  approximately 
1,200  head  of  native-owned  cattle. 
There  are  consequently  between  8,000  and  9,000  head  of  cattle 
in  Northern  Rhodesia,  localised,  except  for  special  purposes,  to  the 
district  around  Fort  Jameson  and  to  the  Tanganyika-Nyasa  plateau. 
Sheep  are  scattered  over  the  territory,  but  are  more  extensively  bred 
on  the  plateau  and  the  district  around  Bangueolo,  and  we  are  informed 
also  in  the  valley  of  the  Loangwa.  Goats  are  distributed  in  most 
villages  throughout.  Dogs  are  kept  in  nearly  every  village  ;  they  are 
quite  neglected,  and  live  principally  on.  offal.  Wherever  possible, 
Europeans  keep  a  few,  generally  of  English  or  colonial  breed ;  and 
m  these  the  mortality  from  trypanosomiasis  is  high,  especially  as 
they  frequently  accompany  their  masters  on  tour.  Horses  are  found 
only  at  Fort  Jameson  and  Fife;  donkeys  are  met  also  at  certain 
up-country  posts  and  seem  to  have  a  high  resistance  to  the  local 
strains  of  trypanosomes. 
2.  Nyasaland. 
We  were  unable  to  devote  any  attention  to  the  question  in 
Nyasaland,  but  the  following  summary,  kindly  furnished  by  the
