  Other 
  insects 
  which 
  become 
  infected 
  with 
  the 
  same 
  disease 
  are 
  : 
  — 
  

   Acridians 
  — 
  Schistocerca 
  peregrina 
  (Europe), 
  Caloptenus 
  sp. 
  (Argentine), 
  

   Stauronotus 
  maroccanus 
  (Algiers) 
  ; 
  Ants 
  — 
  Solenopsis 
  gemminata 
  

   (Argentine), 
  Atta 
  sexdens 
  ; 
  and 
  caterpillars 
  which 
  ravaged 
  cotton 
  

   plantations 
  at 
  Chaco. 
  On 
  the 
  other 
  hand, 
  fowls 
  which 
  ate 
  diseased 
  insects 
  

   did 
  not 
  suffer 
  ; 
  rabbits 
  and 
  guinea-pigs 
  are 
  also 
  immune 
  and 
  apparently 
  

   men 
  are 
  not 
  liable 
  to 
  be 
  attacked 
  ; 
  rats, 
  however, 
  died 
  when 
  inoculated.

  An

  In 
  

   applying 
  d'HereUe's 
  methods 
  to 
  the 
  work 
  in 
  Algeria 
  [see 
  this 
  

   Review, 
  Ser. 
  A, 
  ii, 
  p. 
  238 
  ; 
  and 
  above], 
  three 
  questions 
  arise 
  ; 
  

   these 
  are, 
  whether 
  the 
  coccobacillus 
  which 
  attacks 
  Schistocerca 
  is 
  

   capable 
  of 
  attacking 
  Stauronotus 
  with 
  sufficient 
  virulence 
  to 
  

   cause 
  its 
  death 
  ; 
  whether 
  climatic 
  and 
  other 
  conditions 
  prevailing 
  

   in 
  Algeria 
  allow 
  of 
  the 
  cultures 
  of 
  the 
  bacteria 
  being 
  disseminated 
  

   in 
  the 
  open 
  in 
  places 
  infested 
  with 
  grasshoppers 
  ; 
  and 
  thirdly, 
  

   whether 
  the 
  putrefying 
  bodies 
  of 
  Stauronotus 
  are 
  capable 
  of 
  trans- 
  

   ferring 
  the 
  virus 
  to 
  other 
  insects. 
  It 
  was 
  found 
  that 
  it 
  is 
  possible 
  

   to 
  cause 
  death 
  to 
  Stauronotus 
  within 
  four 
  hours 
  after 
  inoculation 
  with 
  

   cultures 
  of 
  Coccobacillus 
  acridiorum, 
  and 
  that 
  spraying 
  cultures 
  of 
  

   the 
  bacillus 
  in 
  places 
  where 
  Stauronotus 
  occurred, 
  resulted 
  in 
  the 
  death 
  

   of 
  the 
  insects 
  within 
  a 
  few 
  days, 
  but 
  that 
  further 
  propagation 
  of 
  the 
  

   disease 
  through 
  the 
  dead 
  bodies 
  of 
  attacked 
  individuals 
  only 
  occurred 
  

   to 
  a 
  very 
  small 
  extent.

  The 
  Cattedra

  di

  draws 
  the 
  attention 
  of 
  agricul- 
  

   turists 
  to 
  the 
  importance 
  of 
  the 
  proper 
  preparation 
  of 
  Bordeaux 
  

   mixture 
  and 
  the 
  use 
  of 
  phenolphthalein

  paper 
  as 
  a 
  means 
  of 
  

   determining 
  the 
  critical 
  point 
  when 
  the 
  lime 
  and 
  copper 
  are 
  in 
  proper 
  

   proportion.

  So 
  long 
  as 
  these

  are 
  wetted 
  with

  solution 
  they 
  

   remain 
  white, 
  but 
  in 
  alkaline 
  solution 
  they 
  became 
  intensely 
  red. 
  The 
  

   following 
  procedure 
  is 
  advised 
  :— 
  A 
  sulphate 
  of 
  copper 
  solution 
  

   is 
  first 
  made 
  and 
  the 
  milk 
  of 
  lime 
  gradually 
  poured 
  into 
  it, 
  stirring 
  the 
  

   while, 
  and 
  testing 
  from 
  time 
  to 
  time 
  with 
  the 
  paper. 
  The 
  moment 
  the 
  

   paper 
  shews 
  any 
  sign 
  of 
  redness, 
  the 
  addition 
  of 
  lime 
  must 
  be 
  stopped.
