Of  course  it  must  be  admitted  that  the  conditions  at  Ismailia 
were  extremely  favourable,  the  area  of  land  to  be  dealt  with  was 
limited,  and  the  conditions  very  easy,  but  the  results  demonstrate  very 
clearly  the  immediate  effects  of  systematic  anti-malarial  measures. 
2.  Federated  Malay  States 
In  the  Federated  Malay  States  at  Klang  and  Port  Swettenham, 
very  satisfactory  results  have  been  obtained.  Here  the  measures 
adopted  were  extensive  drainage  of  swamps,  mechanical  prophylaxis, 
that  is,  making  the  houses  mosquito-proof  by  means  of  wire  gauze, 
and  quinine  distribution. 
The  following  tables  give  some  of  the  results  .- 
I.  Cases  of  malaria  admitted  to  Klang  Hospital  from  the  two 
towns,  compared  with  those  admitted  from  the  district.

when  the 
anti-malarial 
campaign  was  instituted,  to  23 
in  1905,  while 
an  increase  took  place 
among  those  from  outside.
