of  game.  In  the  country  itself,  opinion  is  divided  on  the  question  of 
the  inter-relation  of  tsetse  flies  and  game.  Some  men  state  most 
positively  that  there  is  no  close  connection  at  all  between  the  twn. 
Others  say  that  buffalo  and  the  fly  are  always  seen  tog'ether  ;  others 
that  elephant  are  the  selected  animals  ;  others  that  kudu  ;  and  so  on. 
These  conflicting  statements  can  be  explained  in  part  by  incorrect 
observation  and  in  part  by  prejudice. 
VI.  GLAND  PALPATION  AND  PUNCTURE 
During  the  period  February  24th  to  June  15th,  1908,  we  palpated 
17,923  natives,  of  whom  3,056  had  palpable  glands  (post  cervical),  and 
with  our  previous  figures  the  totals  are  26,928  and  4,934,  so  that 
about  a  fifth  of  the  people  (i7'05  per  cent.)  present  the  condition. 
These  glands  are  classified*  as  follows:  — 
-P  ’  29,01-  0'58  per  cent. 
'  +  —  ’  ii5>or  2’33  per  cent. 
‘  H - ’  4,791,  or  97-24  per  cent. 
The  results  of  puncture  were  ;  —

Amongst  the  ‘  +  ’  class  we  have  included  two  cases  in  which 
symptoms  of  tuberculosis  were  present  and  in  which  the  gland  juice 
was  purulent,  so  that  when  these  are  excluded  the  percentage  of 
successful  punctures  becomes  77-7.  It  should  be  noted  that  all  the 
The  classification  to  which  we  have  adhered  is  that  used  by  Dutton  and  Todd,  viz.: 
‘  +  ’  glands,  (a)  one  gland,  estimated  size  1-5  x  0-75  cm. 
(^)  several  (3  or  more)  smaller  glands,  the  largest  measuring 
perhaps  ix  0-75  cm, 
+  —  glands,  showing  less  enlargement  than  ‘  -1-  ’  but  more  tlian  ‘  -| - ’ 
'  -t  -  -  '  glands,  (a)  only  one  or  two  glands  measuring  0-5  x  0-25  cm. 
(i)  many  tiny,  usually  hard  and  shot-like  glands,  which  were 
only  just  palpable. 
t  In  two  ol  these  cases,  negative  on  gland  puncture,  and  in  which  there  was 
ito  apparent  cause  for  the  enlargement,  the  blood  and  cerebro-spinal  fluid  were 
centrifuged  and  examined,  but  with  negative  results.
