work*  that  the  description  we  have  given  of  the  ‘  Chunga  ’  trypano¬ 
some  shows  a  marked  similarity  to  T.  fecaudi.  It  is  to  be  observed, 
however,  that  we  have  never  seen  a  trypanosome  of  i4'o  /x ;  our 
smallest  was  I7'I5  /x  ;  the  undulating  membrane  in  our  form  is  less 
developed  than  that  figured  by  Laveran,  and  we  have  the  more 
common  occurrence  of  a  small  flagellum.  This  trypanosome  is 
maintained  at  Pretoria,  and  additional  work  will  make  its  position 
clearer. 
B.  The'  Wallace'  tryfanosome 
In  September  we  examined  an  Irish  terrier  which  had  accompanied 
the  Administrator,  Mr.  Wallace,  on  tour  from  Fort  Jameson. 
Trypanosomes  were  present  in  his  blood,  but  the  dog  died  and  was 
destroyed  before  we  got  an  inoculation.  Mr.  Wallace  thereupon  very 
kindly  telegraphed  to  Fort  Jameson  for  two  dogs  to  be  sent  in  charge 
of  messengers  to  follow  the  same  route.  These  dogs,  born  in 
Fort  Jameson,  and  apparently  in  perfect  health,  left  there  on 
September  24th  and  travelled  via  Nawalia,  Mpika,  Kasama  and 
Abercorn.  One  reached  our  Kambole  camp  on  October  2gth ;  the 
other  is  said  by  the  messengers  to  have  died  of  extreme  weakness 
two  days  before. 
This  dog  ‘  Dip,’  a  short-haired  animal  of  about  35  lbs.  weight,  was 
in  hard  condition  on  arrival  from  the  long  march  ;  on  casual  glance 
he  was  quite  healthy  and  strong,  only  his  membranes  were  somewhat 
pale.  Trypanosomes  were  present  in  his  blood. 
The  dog  refused  food  on  November  1st,  and  on  the  2nd  was 
unable  to  stand  and  was  semi-comatose  ;  his  coat  was  staring  and 
respirations  increased.  During  the  morning  he  had  five  epileptiform 
fits,  lasting  one-half  to  three-quarters  of  a  minute,  during  which  he 
made  violent  attempts  to  rise,  and  snapped  at  any  near  object, 
howling  and  attempting  to  bark  whilst  the  lit  lasted.  As  no  improve¬ 
ment  was  noticed,  he  was  destroyed  by  an  intrapleural  injection  of 
hydrocyanic  acid  at  four  o’clock.  During  these  few  days  his 
temperature  had  not  exceeded  102 ‘5°. 
Autofsy.  Membranes  and  subcutaneous  tissues  somewhat  pale,  but  not 
excessively  so.  There  was  no  increase  of  fluid  in  the  body  cavities.  Lymphatic 
glands  were  all  enlarged,  slightly  oedematous  and  congested.  Other  organs
