  — 
  The 
  disease 
  ravaged 
  the 
  oat 
  crop 
  in 
  all 
  

   the 
  states 
  of 
  the 
  Mississippi 
  valley 
  this 
  year. 
  It 
  is 
  due 
  to 
  a 
  

   micro-organism 
  which 
  has 
  been 
  grown 
  in 
  various 
  culture 
  

   media 
  and 
  the 
  disease 
  produced 
  in 
  oats 
  by 
  inoculation.

  bxMiTH.— 
  In 
  studying 
  hog 
  cholera 
  lately 
  a 
  form 
  was 
  

   discovered 
  in 
  addition 
  to 
  the 
  one 
  known 
  since 
  1885, 
  whidi 
  

   produces 
  the 
  same 
  disease 
  in 
  a 
  milder 
  fashion. 
  This 
  led 
  the 
  

   author 
  to 
  consider 
  the 
  variability 
  of 
  disease 
  germs.
