  This 
  correspondence, 
  on 
  the 
  difficulties 
  experienced 
  by 
  growers 
  

   when 
  cyaniding 
  vines 
  to 
  destroy 
  the 
  mealy 
  bug, 
  emphasises 
  the 
  

   necessity 
  for 
  repeating 
  this 
  process 
  several 
  times 
  and 
  shows 
  that 
  

   failures 
  are 
  often 
  due 
  to 
  the 
  impurity 
  of 
  the 
  materials 
  used. 
  Details 
  

   are 
  given 
  for 
  producing 
  hydrocyanic 
  acid 
  gas 
  [see 
  this 
  Review, 
  

   Ser. 
  A, 
  i, 
  pp 
  312-313], 
  the 
  ingredients 
  being 
  used 
  in 
  the 
  following 
  

   proportions 
  : 
  Cyanide 
  of 
  potassium 
  1, 
  sulphuric 
  acid 
  IJ, 
  water 
  3. 
  The 
  

   required 
  amount 
  of 
  water 
  should 
  be 
  placed 
  in 
  a 
  glass 
  or 
  glazed 
  porcelain 
  

   vessel 
  so 
  large 
  that 
  when 
  the 
  acid 
  and 
  cyanide 
  are 
  added, 
  it 
  is 
  not 
  

   more 
  than 
  half 
  full. 
  Add 
  the 
  acid 
  (commercial 
  sulphuric 
  acid 
  sp. 
  

   gr. 
  66 
  Beaume) 
  and 
  immediately 
  afterwards 
  the 
  cyanide, 
  of 
  not 
  

   less 
  than 
  98-99 
  per 
  cent, 
  purity. 
  The 
  quantities 
  advised 
  for 
  every 
  

   cubic 
  metre 
  of 
  snace 
  are 
  : 
  — 
  10 
  gms. 
  cyanide 
  of 
  potassium, 
  15 
  gms. 
  

   sulphuric 
  acid 
  and 
  30 
  gms. 
  water.
