  no

  Prof. 
  T. 
  B. 
  Smith, 
  in 
  1896, 
  published 
  in 
  Philadelphia, 
  a 
  work 
  

   on 
  Economic 
  Entomology 
  dealing, 
  in 
  Pt. 
  I, 
  with 
  classification 
  and 
  

   structure 
  of 
  insects. 
  With 
  the 
  different 
  Orders 
  of 
  Insects 
  in 
  

   Part 
  II., 
  and 
  in 
  Part 
  III., 
  with 
  various 
  Insecticides, 
  Preventives 
  

   and 
  Machinery. 
  This 
  is 
  perhaps 
  the 
  best 
  general 
  treatise 
  on 
  the 
  

   subject 
  so 
  far 
  published. 
  

  

  In 
  this 
  country 
  we 
  have 
  at 
  last 
  stirred 
  ourselves, 
  and 
  the 
  

   Imperial 
  Bureau 
  of 
  Entomology, 
  with 
  Viscount 
  Harcourt 
  as 
  

   Chairman, 
  and 
  a 
  powerful 
  committee 
  among 
  whom 
  Prof. 
  Poulton 
  

   and 
  Mr. 
  J. 
  C. 
  F. 
  Fryer 
  are 
  our 
  own 
  members, 
  issue 
  in 
  monthly 
  

   numbers 
  the 
  " 
  Review 
  of 
  Applied 
  Entomology," 
  which 
  deals 
  

   chiefly 
  with 
  the 
  Medical 
  and 
  Veterinary 
  aspect 
  of 
  the 
  subject, 
  

   and 
  the 
  "Bulletin 
  of 
  Entomological 
  Research," 
  which 
  deals 
  with 
  

   insectS' 
  injurious 
  to 
  mankind 
  as 
  well 
  as 
  to 
  crops, 
  etc., 
  in 
  Africa 
  

   and 
  other 
  foreign 
  possessions. 
  

  

  T.

  Theobald, 
  of 
  the 
  Wye

  has 
  

   written 
  several 
  volumes 
  on 
  the 
  subject.

   are
