  be 
  identified. 
  The 
  muslin 
  is 
  soaked 
  and 
  washed 
  in 
  clean 
  water 
  after 
  each 
  

   examination. 
  Generally 
  mixed 
  infections 
  of 
  larvae 
  are 
  found, 
  and 
  these 
  have 
  

   proved 
  of 
  great 
  use 
  in 
  training 
  the 
  staff 
  of 
  the 
  mosquito 
  brigade. 
  

  

  All 
  members 
  of 
  the 
  mosquito 
  brigade 
  are 
  trained 
  to 
  capture 
  and 
  identify 
  adults,, 
  

   a 
  most 
  valuable 
  adjunct 
  to 
  the 
  larval 
  index 
  of 
  a 
  town, 
  and 
  the 
  senior 
  members 
  are 
  

   taught 
  to 
  recognise 
  males 
  and 
  females 
  of 
  Anopheles, 
  Culex 
  and 
  Stegomyia. 
  

  

  For 
  obtaining 
  adults 
  they 
  are 
  supplied 
  with 
  short 
  glass 
  tubes 
  about 
  six 
  inches 
  

   long 
  and 
  one 
  inch 
  in 
  diameter 
  ; 
  a 
  plug 
  of 
  cotton- 
  wool 
  soaked 
  with 
  chloroform 
  is 
  

   placed 
  in 
  the 
  bottom 
  of 
  each 
  and 
  the 
  tube 
  is 
  corked. 
  With 
  this 
  simple 
  contrivance 
  

   resting 
  adults 
  can 
  be 
  caught 
  with 
  ease. 
  The 
  adults 
  so 
  collected 
  are 
  pinned 
  out 
  by 
  

   their 
  respective 
  captors 
  and 
  on 
  their 
  return 
  to 
  the 
  Health 
  Office 
  are 
  submitted 
  for 
  

   examination. 
  By 
  these 
  means 
  we 
  secure 
  an 
  ample 
  supply 
  of 
  specimens 
  for 
  exchange 
  

   or 
  for 
  teaching 
  purposes. 
  

  

  The 
  training 
  of 
  natives 
  requires 
  a 
  great 
  amount 
  of 
  patience, 
  but 
  if 
  one 
  is 
  able 
  

   to 
  interest 
  them 
  in 
  their 
  work, 
  the 
  trouble 
  spent 
  on 
  explaining 
  the 
  life-history 
  

   and 
  habits 
  of 
  the 
  insects 
  they 
  are 
  expected 
  to 
  control 
  is 
  well 
  repaid.
