  The 
  Mycetozoa. 
  

  

  " 
  The 
  Mycetozoa 
  are 
  a 
  group 
  of 
  organisms 
  lymg 
  near 
  the 
  

   border 
  line 
  which 
  separates 
  plants 
  from 
  animals. 
  They 
  are 
  now 
  

   usually 
  considered 
  to 
  belong 
  to 
  the 
  Protozoa 
  in 
  the 
  animal 
  king- 
  

   dom. 
  

  

  " 
  They 
  live 
  amongst 
  decaying 
  leaves 
  or 
  in 
  moist 
  dead 
  wood, 
  and 
  

   are 
  to 
  be 
  found 
  apparently 
  all 
  over 
  the 
  world, 
  wherever 
  decaying 
  

   vegetable 
  matter 
  may 
  afford 
  them 
  means 
  of 
  subsistence. 
  

  

  " 
  Their 
  life-history 
  may 
  be 
  briefly 
  narrated.
