  -Leaf 
  of 
  Hop, 
  the 
  Left 
  Half 
  of 
  which 
  was 
  Sprayed 
  with 
  Lime- 
  

   Sulphur 
  and 
  Flour 
  Paste, 
  and 
  the 
  Right 
  Half 
  with 
  Lime-Sulphur 
  

   Alone. 
  (Original.) 
  

  

  Note 
  thin 
  the 
  spray 
  Is 
  uniformly 
  distributed 
  on 
  the 
  Left 
  ball 
  of 
  the 
  leaf; 
  on 
  the 
  right 
  half, 
  

   however, 
  it 
  Is 
  collected 
  in 
  separate 
  drops 
  or 
  patches, 
  owing 
  to 
  the 
  pubescence 
  of 
  the 
  leaf.
