  same 
  species 
  growing 
  in 
  distant 
  localities, 
  and 
  

   it 
  would 
  be 
  improbable 
  they 
  should 
  be 
  affected 
  

   in 
  the 
  same 
  way. 
  Hence 
  we 
  should 
  conclude 
  

   that 
  when 
  a 
  species 
  is 
  converted 
  into 
  a 
  new 
  type 
  

   in 
  one 
  locality 
  this 
  is 
  only 
  to 
  be 
  considered 
  as 
  

   one 
  of 
  numerous 
  possible 
  ones, 
  and 
  its 
  alteration 
  

   would 
  not 
  in 
  the 
  least 
  change 
  the 
  aspect 
  of 
  the 
  

   remainder 
  of 
  the 
  species. 
  

  

  But 
  even 
  with 
  this 
  restriction 
  the 
  general 
  be- 
  

   lief 
  is 
  not 
  supported 
  by 
  the 
  evidence 
  of 
  the 
  even- 
  

   ing-primroses. 
  There 
  is 
  neither 
  a 
  slow 
  nor 
  a 
  

   sudden 
  change 
  of 
  all 
  the 
  individuals. 
  On 
  the 
  

   contrary, 
  the 
  vast 
  majority 
  remain 
  unchanged; 
  

   thousands 
  are 
  seen 
  exactly 
  repeating 
  the 
  orig- 
  

   inal 
  prototype 
  yearly, 
  both 
  in 
  the 
  native 
  field 
  

   and 
  in 
  my 
  garden. 
  There 
  is 
  no 
  danger 
  that 
  

   lamarckiana 
  might 
  die 
  out 
  from 
  the 
  act 
  of 
  mu- 
  

   tating, 
  nor 
  that 
  the 
  mutating 
  strain 
  itself 
  would 
  

   be 
  exposed 
  to 
  ultimate 
  destruction 
  from 
  this 
  

   cause. 
  

  

  In 
  older 
  swarms, 
  such 
  as 
  Drab 
  a 
  or 
  HeliantJie- 
  

   mum, 
  no 
  such 
  center, 
  around 
  which 
  the 
  various 
  

   forms 
  are 
  grouped, 
  is 
  known. 
  Are 
  we 
  to 
  con- 
  

   clude 
  therefore 
  that 
  the 
  main 
  strain 
  has 
  died 
  

   out? 
  Or 
  is 
  it 
  perhaps 
  concealed 
  among 
  the 
  

   throng, 
  being 
  distinguished 
  by 
  no 
  peculiar 
  char- 
  

   acter 
  ? 
  If 
  our 
  gigas 
  and 
  rubrinervis 
  were 
  grow- 
  

   ing 
  in 
  equal 
  numbers 
  with 
  the 
  lamarckiana 
  in 
  

   the 
  native 
  field, 
  would 
  it 
  be 
  possible 
  to 
  decide
