  enabled 
  to 
  give 
  it 
  more 
  intense 
  attention. 
  Wiiat 
  an 
  intimate 
  know- 
  

   ledge 
  have 
  Zeller, 
  Stainton, 
  our 
  worthy 
  Secretary, 
  and 
  others 
  thus 
  

   acquired 
  of 
  the 
  Micro-LepidojDtera 
  ; 
  Mr. 
  Dawson 
  of 
  the 
  British 
  

   Geodephaga 
  ; 
  Mr. 
  Doubleday 
  and 
  Mr. 
  Edwin 
  Shepherd 
  of 
  British 
  

   Lepidoptera 
  ; 
  Mr. 
  Walton 
  of 
  British 
  Curculionidae 
  ; 
  Schonherr 
  of 
  

   Curculionidse 
  generally 
  ; 
  Chevrolat 
  of 
  Cerambycidse 
  ; 
  Pictet 
  of 
  Phry- 
  

   ganidae 
  ; 
  Gravenhorst 
  of 
  Ichneumonidae 
  ; 
  Mr. 
  Smith 
  of 
  Aculeate 
  

   Hymenoptera, 
  and 
  especially 
  of 
  our 
  British 
  bees 
  ; 
  Meigen 
  and 
  

   Walker 
  of 
  Diptera 
  ! 
  I 
  might 
  cite 
  fifty 
  examples 
  equally 
  striking, 
  and 
  

   all 
  equally 
  establishing 
  the 
  fact 
  that 
  the 
  more 
  restricted 
  the 
  range 
  of 
  

   inquiry, 
  the 
  more 
  certain, 
  precise, 
  and 
  durable 
  will 
  be 
  its 
  results. 
  The 
  

   debilitating 
  eflfect 
  of 
  desultory 
  study 
  is 
  obvious 
  to 
  every 
  psychologist. 
  

   It 
  is 
  with 
  mind 
  as 
  with 
  matter, 
  the 
  more 
  extensive 
  the 
  surface 
  it 
  

   covers 
  the 
  more 
  attenuated 
  will 
  be 
  the 
  covering. 
  Study, 
  in 
  order 
  to 
  

   be 
  productive 
  of 
  useful 
  results, 
  must 
  be 
  concentrated 
  and 
  systema- 
  

   tised: 
  it 
  then 
  shines 
  brightly 
  forth 
  on 
  the 
  path 
  of 
  the 
  future 
  student. 
  

  

  The 
  communications 
  which 
  have 
  struck 
  me 
  as 
  possessing 
  the 
  most 
  

   absorbing 
  interest 
  are 
  such 
  as 
  relate 
  to 
  insects 
  which 
  exert 
  an 
  

   important 
  influence 
  over 
  man, 
  whether 
  for 
  his 
  benefit 
  or 
  injury 
  : 
  such, 
  

   for 
  instance, 
  as 
  that 
  by 
  Mr. 
  Hanbur^^, 
  on 
  the 
  wax 
  insects 
  of 
  China 
  ; 
  

   that 
  by 
  Mr. 
  Oswell, 
  on 
  the 
  cattle 
  fly 
  of 
  Africa 
  ; 
  and 
  that 
  by 
  

   Captain 
  Cox, 
  on 
  Scolytus 
  : 
  in 
  these 
  instances 
  man 
  is 
  brought 
  into 
  

   absolute 
  contact 
  with 
  the 
  insect 
  : 
  in 
  the 
  first 
  this 
  contact 
  is 
  entirely 
  

   beneficial 
  ; 
  in 
  the 
  others 
  entirely 
  the 
  reverse 
  : 
  and 
  mankind 
  would 
  be 
  

   infinitely 
  indebted 
  to 
  the 
  entomologist 
  who 
  should, 
  by 
  attentive 
  ob- 
  

   servation, 
  detect 
  the 
  means 
  of 
  increasing 
  the 
  benefit 
  or 
  of 
  mitigating 
  

   the 
  injury. 
  To 
  the 
  discussions 
  which 
  have 
  resulted 
  from 
  these 
  and 
  

   other 
  communications, 
  1 
  have 
  always 
  listened 
  with 
  the 
  deepest 
  in- 
  

   terest 
  and 
  most 
  profound 
  attention 
  ; 
  and 
  I 
  have 
  been 
  peculiarly 
  

   gratified 
  to 
  observe 
  the 
  uniformly 
  courteous 
  manner 
  in 
  which 
  they 
  

   have 
  been 
  conducted. 
  There 
  is 
  scarcely 
  one 
  scientific 
  subject 
  which 
  

   we 
  can 
  all 
  view 
  in 
  the 
  same 
  light, 
  and 
  the 
  difference 
  of 
  opinion, 
  which 
  

   of 
  necessity 
  results 
  from 
  the 
  different 
  mental 
  constitution 
  of 
  individuals, 
  

   is 
  in 
  itself 
  an 
  important 
  element 
  in 
  our 
  search 
  after 
  that 
  truth 
  which 
  is 
  

   the 
  kernel 
  of 
  the 
  whole 
  question, 
  the 
  reward 
  we 
  obtain 
  for 
  our 
  labour 
  

   in 
  clearing 
  away 
  the 
  tasteless 
  and 
  seemingly 
  impenetrable 
  husk 
  with 
  

   which 
  we 
  so 
  often 
  find 
  it 
  invested. 
  Nevertheless, 
  this 
  difference 
  

   should 
  ever 
  be 
  urged, 
  as 
  it 
  has 
  been, 
  with 
  that 
  courtesy 
  and 
  that 
  re- 
  

   spect 
  for 
  the 
  feelings 
  and 
  the 
  judgment 
  of 
  others, 
  which 
  dignifies 
  alike 
  

   the 
  original 
  opinion 
  and 
  the 
  objection, 
  and 
  which 
  evinces 
  a 
  love 
  of 
  

   truth 
  overcoming 
  a 
  love 
  of 
  conquest. 
  I 
  could 
  wish 
  that 
  a 
  month's 
  notice
