in  our  first  published  report,  we  reiterated  these  suggestions  with  a 
few  additional  ones  of  minor  importance.  The  regulations  which 
were  finally  adopted  were  much  along  these  lines,  and  are,  briefly: 
1.  The  Congo  Free  State  and  German  East  Africa  are  regarded 
as  infected  countries,  and  communication  with  them  has  been 
stopped. 
2.  All  villages,  except  in  two  or  three  instances,  have  been  moved 
away  from  contact  with  Gl.  palpalis. 
3.  Certain  districts  of  the  country  are  regarded  as  infected,  and 
communication  between  them  and  the  other  portions  of  the  territory 
prohibited.  These  infected  areas  are  three  in  number,  one  including 
the  comitry  around  Lake  Tanganyika,  the  second  that  around  Lake 
Mweru,  and  the  third  that  along  the  I^uapula  river. 
4.  Three  special  medical  officers  have  been  appointed,  one  for 
each  of  the  infected  regions,  to  travel  constantly  and  search  for  cases 
of  the  disease. 
5.  All  cases  of  human  trypanosomiasis  are  segregated  in  special 
camps,  in  fly-free  areas,  for  treatment. 
6.  All  canoes  have  been  confiscated,  and  fishing  on  ‘fly’ 
(i.e.,  Gl.  palpalis)  waters  forbidden. 
7.  Clearings  are  made  at  necessary  places,  e.g.,  around  the  few 
villages  which  have  been  allowed  to  remain  on  the  shores  of  Lake 
Mweru,  and  at  several  ferries. 
rhe  vigorous  enforcement  of  these  regulations  seems  to  be 
meeting  with  success,  for  from  November,  1908,  to  January,  1909,  no 
further  cases  of  the  disease  were  found.  The  efficiency  of  the  scheme 
depends  upon  the  application  of  gland  palpation  and  puncture,  and, 
so  far  as  one  can  see,  it  is  working  satisfactorily,  but  some  time  must 
necessarily  elapse  before  a  definite  opinion  can  be  given  as  to  what 
the  ultimate  result  will  be.  Apart  from  the  transmission  of  the 
disease  by  coitus,*  and  the  question  of  whether  any  other  tsetse  fly 
than  Gl.  palpalis  is  a  natural  transmitter  of  T .  ganibunst, 
this  will  largely  depend  upon  the  personnel  of  the  staff,  and  in  this 
connection  we  cannot  do  better  than  quote  the  remarks  of  Neavet  :  —
