  In 
  taking 
  the 
  measurements 
  and 
  in 
  calculating 
  the 
  percentage 
  ratios 
  of 
  width 
  to 
  

   length 
  decimals 
  under 
  0.05 
  were 
  neglected 
  and

  1. 
  

  

  From 
  this 
  table 
  it 
  is 
  evident 
  that 
  at 
  the 
  beginning 
  of 
  the 
  experiment, 
  

   .August 
  2, 
  1902, 
  the 
  width 
  of 
  this 
  lot 
  of 
  oysters 
  was 
  on]j 
  53 
  per 
  cent 
  

   of 
  the 
  length, 
  whereas 
  on 
  September 
  2 
  it 
  was 
  62 
  per 
  cent, 
  an 
  increase 
  

   of 
  9 
  per 
  cent; 
  on 
  September 
  18 
  it 
  was 
  6Q 
  per 
  cent, 
  an 
  increase 
  over 
  

   the 
  original 
  ratio 
  of 
  13 
  per 
  cent. 
  This 
  marked 
  change, 
  easily 
  notice- 
  

   able 
  without 
  measurements, 
  was 
  very 
  surprising 
  because 
  it 
  took 
  place 
  

   in 
  forty 
  -eight 
  days 
  after 
  the 
  liberation 
  of 
  the 
  oj^sters 
  from 
  their 
  

   original 
  oppressive 
  environment. 
  

  

  To 
  comyjare 
  these 
  oysters 
  with 
  the 
  normally 
  shaped 
  ones 
  from 
  the 
  

   experimental 
  bed 
  in 
  Newport 
  Eiver, 
  thirty 
  young 
  oj'sters 
  from 
  this 
  

   locality 
  were 
  measured 
  in 
  jthe 
  same 
  way:
