  all 
  of 
  which 
  was 
  of 
  great

  and 
  the 
  competent 
  and 
  speedy

   results. 
  A 
  resolution 
  was 
  passed 
  in 
  the

  adopted

   the

  The 
  authors 
  had 
  

   examined 
  the

  75 
  woody 
  or 
  shrubby 
  plants, 
  with

  of 
  discovering 
  the 
  most 
  favorable

  the 
  demonstration 
  

   ^' 
  protoplasmic 
  continuity. 
  While 
  it 
  was 
  thought

  strands
