  Here 
  he 
  stopped, 
  and, 
  raising 
  himself 
  upon 
  his 
  prolegs, 
  moved 
  the 
  

   anterior 
  part 
  of 
  his 
  body 
  to 
  and 
  fro, 
  as 
  if 
  he 
  were 
  trying 
  to 
  scent 
  the 
  

   leader. 
  He 
  soon 
  discontinued 
  this, 
  and 
  resumed 
  his 
  natural 
  position 
  

   again, 
  appearing, 
  however, 
  for 
  some 
  time 
  very 
  restless. 
  While 
  this 
  

   had 
  been 
  going 
  on 
  the 
  rest 
  of 
  the 
  caterpillars 
  had 
  crowded 
  up 
  to 
  the 
  

   front 
  one 
  ; 
  they 
  appeared 
  for 
  some 
  time 
  very 
  restless, 
  but 
  finally 
  

   settled 
  in 
  a 
  close 
  bunch, 
  in 
  which 
  position 
  they 
  all 
  remained. 
  One 
  

   here 
  and 
  one 
  there 
  would 
  often 
  become 
  restless 
  for 
  a 
  few 
  minutes, 
  but 
  

   end 
  by 
  settling 
  again 
  in 
  its 
  former 
  position 
  in 
  the 
  bunch. 
  I 
  now 
  

   marked 
  the 
  original 
  leader 
  (he 
  had 
  been 
  kept 
  away 
  from 
  the 
  others 
  all 
  

   of 
  this 
  time) 
  by 
  putting 
  a 
  little 
  white 
  paint 
  on 
  his 
  back, 
  and 
  then, 
  

   picking 
  him 
  up 
  on 
  a 
  small 
  piece 
  of 
  paper, 
  dropped 
  him 
  back 
  at 
  the 
  

   edge 
  of 
  the 
  group. 
  The 
  leader 
  in 
  the 
  meantime 
  had 
  been 
  walking 
  

   around, 
  evidently 
  seeking 
  the 
  other 
  caterpillars, 
  and 
  when 
  he 
  returned 
  

   to 
  the 
  bunch 
  began 
  to 
  walk 
  restlessly 
  around 
  near 
  its 
  edge. 
  In 
  a 
  few 
  

   minutes 
  he 
  started 
  off 
  away 
  from 
  the 
  others, 
  and 
  these 
  began 
  to 
  follow 
  

   him, 
  moving 
  in 
  a 
  regular 
  procession. 
  

  

  '' 
  Different 
  masses 
  of 
  the 
  eggs 
  were 
  now 
  brought 
  into 
  my 
  room, 
  a 
  

   few 
  each 
  week, 
  and 
  when 
  the 
  caterpillars 
  hatched 
  a 
  few 
  experiments 
  

   were 
  carried 
  on 
  to 
  see 
  if 
  the 
  removal 
  of 
  the 
  leader 
  always 
  affected 
  the 
  

   followers 
  in 
  the 
  same 
  way, 
  and 
  if 
  a 
  new 
  caterpillar 
  would 
  not 
  assume 
  

   the 
  leadership, 
  and 
  be 
  followed 
  by 
  the 
  rest. 
  The 
  results 
  1 
  have 
  

   thought 
  it 
  best 
  to 
  write 
  out 
  briefly, 
  and 
  not 
  to 
  arrange 
  them 
  in 
  a 
  

   tabulated 
  form. 
  The 
  first 
  set 
  contains 
  those 
  in 
  which 
  the 
  old 
  leader, 
  

   upon 
  being 
  returned 
  to 
  the 
  bunch, 
  resumed 
  command 
  ; 
  and 
  the 
  second 
  

   lot, 
  those 
  experiments 
  in 
  which 
  a 
  new 
  caterpillar 
  became 
  the 
  leader. 
  

   There 
  then 
  follow 
  a 
  few 
  experiments 
  differing 
  from 
  those 
  contained 
  in 
  

   the 
  first 
  two 
  lots. 
  When 
  the 
  number 
  of 
  caterpillars 
  forming 
  the 
  line 
  

   was 
  counted, 
  this 
  is 
  given 
  ; 
  but 
  in 
  some 
  cases, 
  however, 
  the 
  number 
  

   which 
  formed 
  the 
  line 
  was 
  not 
  noted. 
  

  

  " 
  In 
  nearly 
  every 
  instance 
  the 
  removal 
  of 
  the 
  leader 
  brought 
  about 
  

   at 
  first 
  the 
  same 
  result. 
  When 
  I 
  removed 
  him 
  I 
  would 
  draw 
  a 
  line 
  

   on 
  the 
  paper, 
  marking 
  a 
  place 
  where 
  his 
  head 
  was 
  before 
  removal. 
  

   When 
  the 
  second 
  caterpillar 
  in 
  the 
  line 
  reached 
  this 
  point, 
  he 
  always 
  

   stopped, 
  rarely 
  crossing 
  the 
  line 
  ; 
  and 
  when 
  the 
  bunch 
  was 
  formed 
  it 
  

   was 
  always 
  back 
  of 
  the 
  line.
