  THE 
  ZOOLOGIST. 
  

  

  It 
  is 
  only 
  from 
  those 
  who 
  have 
  engaged 
  in 
  monographic 
  work 
  

   that 
  Sir 
  G. 
  Hampson 
  can 
  hope 
  for 
  real 
  sympathetic 
  appreciation, 
  

   while 
  it 
  is 
  also 
  from 
  the 
  same 
  quarter 
  that 
  criticism 
  must 
  be 
  

   expected. 
  Human 
  nature 
  being 
  as 
  it 
  is, 
  we 
  do 
  not 
  rejoice 
  at 
  

   seeing 
  our 
  specific 
  creations 
  relegated 
  to 
  the 
  synonymic 
  basket 
  ; 
  

   some 
  may 
  regret 
  that 
  their 
  classificatory 
  proposals 
  have 
  not 
  been 
  

   followed, 
  others 
  that 
  their 
  species 
  are 
  regarded 
  as 
  varieties, 
  their 
  

   varieties 
  estimated 
  as 
  species, 
  their 
  new 
  genera 
  as 
  unnecessary 
  

   foundations, 
  or 
  the 
  genera 
  they 
  have 
  used 
  as 
  mistaken 
  ones 
  ; 
  

   and 
  yet 
  this 
  is 
  the 
  very 
  work 
  that 
  a 
  revisionist 
  must 
  undertake. 
  

   Again, 
  the 
  monographer, 
  strange 
  to 
  say, 
  is 
  always 
  still 
  the 
  

   pioneer, 
  for 
  no 
  classification 
  is 
  final, 
  no 
  revision 
  the 
  last 
  word 
  ; 
  

   it 
  is 
  the 
  excellence 
  of 
  one 
  monograph 
  that 
  makes 
  a 
  better 
  one 
  

   possible, 
  and 
  this 
  is 
  no 
  paradox, 
  but 
  is 
  an 
  acknowledgment 
  which 
  

   is 
  often 
  absent, 
  or 
  none 
  too 
  kindly 
  made 
  in 
  a 
  subsequent 
  work. 
  

   By 
  the 
  aid 
  of 
  a 
  good 
  descriptive 
  catalogue 
  like 
  this 
  volume, 
  it 
  

   become 
  possible 
  for 
  any 
  capable 
  entomologist 
  to 
  make 
  an 
  ex- 
  

   haustive 
  study 
  of 
  some 
  small 
  and 
  special 
  group, 
  when, 
  if 
  an 
  error 
  

   can 
  be 
  discovered, 
  however 
  small, 
  or 
  a 
  misconception 
  sustained, 
  

   the 
  fact 
  is 
  usually 
  accentuated 
  with 
  much 
  satisfaction 
  by 
  an 
  early 
  

   application 
  of 
  the 
  printing 
  machine. 
  Such 
  is 
  the 
  fate 
  of 
  the 
  

   monographic 
  revisionist 
  ! 
  He 
  is 
  never 
  spoiled 
  by 
  universal 
  

   flattery. 
  He 
  is 
  supposed 
  to 
  correct 
  any 
  error, 
  and 
  expected 
  to 
  

   never 
  make 
  one 
  himself. 
  Seldom 
  is 
  the 
  dictum 
  of 
  Horace 
  ap- 
  

   plied, 
  that 
  the 
  best 
  man 
  is 
  one 
  that 
  hath 
  fewest 
  faults. 
  

  

  This 
  volume 
  is 
  a 
  standard 
  one, 
  and 
  in 
  the 
  best 
  sense 
  advances 
  

   the 
  study 
  of 
  Lepidoptera. 
  

  

  Evolution 
  and 
  Adaptation.

  Hunt

  This 
  book 
  is 
  another 
  contribution 
  to 
  the 
  opinion 
  that 
  natural 
  

   selection 
  is 
  not 
  the 
  dominant 
  factor 
  in 
  evolution 
  as 
  held 
  by 
  so 
  

   many 
  biologists. 
  For 
  an 
  American 
  treatise, 
  it 
  is 
  noteworthy 
  by 
  

   its 
  very 
  qualified 
  Lamarckian 
  adhesion. 
  On 
  the 
  question 
  of 
  

   the 
  inheritance 
  of 
  acquired 
  characters, 
  Dr. 
  Morgan's 
  verdict 
  is 
  

   " 
  not 
  proven," 
  with 
  the 
  rider 
  that 
  he 
  is 
  " 
  not 
  sure 
  that 
  we 
  should 
  

   not 
  be 
  justified 
  at 
  present 
  in 
  claiming 
  that 
  the 
  theory 
  is 
  un- 
  

   necessary, 
  and 
  even 
  improbable."
