  These 
  measurements 
  show 
  that 
  in 
  some 
  cases 
  a 
  young 
  oj^ster 
  is 
  actu- 
  

   ally 
  wider 
  than 
  it 
  is 
  long, 
  and 
  the 
  occurrence 
  of 
  such 
  makes 
  the 
  ratio 
  

   of 
  width 
  to 
  length 
  very 
  high. 
  For 
  the 
  present 
  lot 
  it 
  was 
  79 
  per 
  cent. 
  

  

  The 
  oysters 
  used 
  in 
  Experiment 
  II 
  were, 
  according 
  to 
  their 
  size, 
  of 
  

   about 
  the 
  same 
  age 
  as 
  the 
  normal 
  spat, 
  and 
  the 
  two 
  groups 
  can 
  there- 
  

   fore 
  be 
  compared. 
  At 
  the 
  beginning 
  the 
  width 
  of 
  the 
  experiment 
  

   oysters 
  was 
  only 
  53 
  per 
  cent 
  of 
  their 
  length, 
  or 
  26 
  per 
  cent 
  less 
  than 
  

   the 
  similar 
  relation 
  in 
  the 
  normal 
  spat. 
  On 
  September 
  2 
  it 
  was 
  62 
  

   per 
  cent, 
  or 
  17 
  per 
  cent 
  below 
  normal, 
  and 
  on 
  September 
  18 
  it 
  was 
  6Q 
  

   per 
  cent, 
  or 
  13 
  per 
  cent 
  below 
  normal, 
  showing 
  a 
  steady 
  approxima- 
  

   tion 
  to 
  the 
  condition 
  found 
  in 
  oysters 
  which 
  have 
  never 
  been 
  subject 
  

   to 
  crowding. 
  

  

  This 
  comparison 
  between 
  the 
  normal 
  spat 
  and 
  the 
  young 
  elongated 
  

   forms 
  suggested 
  a 
  similar 
  one 
  between 
  adults 
  of 
  normal 
  shape 
  and 
  

   elongated 
  oysters 
  of 
  about 
  the 
  same 
  size 
  and 
  approximately 
  the 
  same 
  

   age. 
  The 
  length 
  and 
  width 
  of 
  these 
  were 
  measured 
  by 
  the 
  method 
  

   emploj^ed 
  with 
  the 
  younger 
  oysters.
