The  following  inoculations  were  made  from  other  animals  at 
'  Scotsdale  ’ ;  it  is  believed  that  the  trypanosome  is  the  same. 
From  Cow  A. 
May,  1908  :  White  rat  0-5  c.cm.  intraperitoneally. 
August,  190S:  White  rat  3-0  c.cm..  Guinea-pig  5-0  c.cm.,  intraperitoneally 
No  infection  resulted. 
From  Cow  B. 
May,  1908:  White  rat  i-o  c.cm.  intraperitoneally. 
August,  190S:  White  rat  5-0  c.cm.  intraperitoneally. 
No  infection  resulted. 
FKO.M  C.A.LF. 
August,  1908:  Guinea-pig  lo-o  c.cm.  intraperitoneally. 
No  infection  resulted. 
At  oul  filst  visit  to  Chinsali,  the  position  of  which  with  regard 
to  Gl.  morsitans  has  already  been  discussed,  two  cows  in 
a  herd  of  nine  adults  were  found  infected.  No  reliable  history 
regarding  these  animals  could  be  obtained  owing  to  a  change  of 
Native  Commissioner  and  the  fact  that  no  individual  records  are 
kept ,  but  it  IS  possible  that  these  animals  came  from  Mirongo  three 
months  prior  to  our  visit.  Gl.  morsitans  exists  on  that  road. 
These  same  animals  were  again  seen  at  Ikomba  Government 
Farm  in  August  and  September  and  were  still  infected.  The 
drafting  of  these  cases  to  a  healthy  area  is  a  source  of  danger  which 
could  be  avoided;  it  shows  also  the  desirability  of  branding  and 
identifying  all  stock  in  these  areas,  since  it  was  only  by  our  own  notes 
and  enquiries  that  they  were  proved  to  be  the  same  cattle,  and  not 
cases  of  trypanosomiasis  occurring  spontaneously  on  this  Farm. 
The  morphology  of  this  trypanosome  is  identical  with  that  at 
Scotsdale,  and  we  consider  it  probable  that  they  are  the  same  species. 
The  following  inoculations  v.'ere  made  at  Chinsali:  — 
Cow  A. 
May,  1908:  White  rat  0-5  c.cm.  intraperitoneally.  Guinea-pig  2-0  c  cm 
intraperitoneally. 
Cow  C. 
August,  190S :  White  rat  2-0  c.cm.  intraperitoneally.  Guinea-pier  6-o  c  cm 
intraperitoneally. 
In  no  case  did  infection  result. 
At  Kasama,  in  May,  we  found  a  sheep,  which  had  arrived  from 
Lake  Bangueolo  four  days  previously,  showing  trypanosomes  which 
are  morphologically  identical  with  those  occurring  in  the  Scotsdale
