  — 
  Professors 
  Korschelt 
  and 
  

   Heider's 
  great 
  work 
  is 
  one 
  of 
  the 
  most 
  valuable, 
  if 
  not 
  the 
  most 
  

   valuable, 
  of 
  all 
  the 
  biological 
  text-books 
  which 
  have 
  appeared 
  in 
  

   the 
  present 
  decade. 
  All 
  English-speaking 
  students 
  of 
  biology 
  are 
  

   deeply 
  indebted 
  to 
  the 
  several 
  translators 
  for 
  attempting 
  their 
  

   part 
  of 
  the 
  work, 
  as 
  well 
  as 
  for 
  the 
  painstaking 
  labor 
  they 
  have 
  

   bestowed 
  upon 
  it. 
  Nothing 
  can 
  give 
  a 
  better 
  idea 
  of 
  the 
  recent 
  

   progress 
  of 
  invertebrate 
  embryology 
  than 
  a 
  comparison 
  of 
  this 
  

   work 
  with 
  the 
  thin 
  first 
  volume 
  of 
  Balfour's 
  Comparative 
  

   Embryology 
  which 
  appeared 
  in 
  1880. 
  The 
  vast 
  mass 
  of 
  litera- 
  

   ture 
  which 
  appeared 
  during 
  the 
  ten 
  years 
  from 
  the 
  time 
  of 
  

   Balfour's 
  work 
  was 
  carefully 
  reviewed 
  by 
  Korschelt 
  and 
  Heider 
  

   and 
  condensed 
  into 
  their 
  work, 
  which 
  gives 
  full 
  citations 
  for 
  each 
  

   investigator's 
  contribution 
  to 
  the 
  subject 
  in 
  hand, 
  and 
  thus 
  

   becomes 
  a 
  complete 
  guide 
  to 
  the 
  literature 
  of 
  the 
  period. 
  Some 
  

   idea 
  of 
  the 
  extent 
  of 
  this 
  literature 
  is 
  given 
  by 
  the 
  indices 
  to 
  

   authors, 
  the 
  index 
  in 
  each 
  of 
  the 
  three 
  volumes 
  of 
  the 
  translation 
  

   containing 
  250, 
  or 
  more, 
  names. 
  

  

  Many 
  additions 
  have 
  been 
  made 
  to 
  the 
  original 
  text 
  both 
  by 
  

   the 
  authors 
  and 
  the 
  translators, 
  so 
  that 
  the 
  work 
  is 
  in 
  great 
  

   measure 
  brought 
  down 
  to 
  the 
  time 
  of 
  publication. 
  This 
  is 
  

   especially 
  true 
  of 
  the 
  bibliographical 
  lists 
  which 
  include 
  the 
  

   recent 
  literature 
  very 
  fully. 
  The 
  translation 
  throughout, 
  like 
  

   that 
  of 
  Prof. 
  Mark's 
  admirable 
  translation 
  of 
  Hertwig's 
  classical 
  

   Text-book 
  of 
  the 
  Embryology 
  of 
  Man 
  and 
  Mammals, 
  cannot 
  be 
  

   too 
  highly 
  praised. 
  It 
  is 
  clear 
  and 
  accurate 
  without 
  the 
  use 
  of 
  

   German 
  words 
  or 
  German 
  idioms. 
  In 
  rendering 
  Anlage 
  into 
  

   English 
  Prof. 
  Mark 
  introduced 
  the 
  word 
  fundament^ 
  which 
  was 
  

   used 
  throughout 
  the 
  first 
  volume. 
  In 
  the 
  subsequent 
  volumes 
  

   Dr. 
  Woodward 
  has 
  substituted 
  the 
  much 
  abused 
  word 
  rudiment., 
  

   returning 
  to 
  the 
  primary 
  meaning 
  of 
  the 
  word 
  which 
  Darwin 
  and 
  

   most 
  recent 
  biologists 
  have 
  unfortunately 
  misapplied 
  to 
  vestigial 
  

   structures. 
  This 
  appears 
  to 
  the 
  writer 
  a 
  reasonable 
  substitute 
  lor 
  

   fundament, 
  primordium, 
  proton, 
  etc., 
  as 
  well 
  as 
  for 
  the 
  un-English 
  

   Anlage, 
  and 
  a 
  possible 
  solution 
  of 
  a 
  much 
  vexed 
  question, 
  but 
  it 
  

   is 
  scarcely 
  to 
  be 
  expected 
  that 
  it 
  will 
  be 
  generally 
  accepted. 
  The 
  

   mechanical 
  execution 
  of 
  the 
  work 
  is 
  excellent, 
  but 
  the 
  change 
  in 
  

   the 
  size 
  of 
  the 
  page 
  after 
  the 
  first 
  volume 
  appears 
  unforlunate. 
  

  

  The 
  translators 
  of 
  the 
  first 
  volume 
  were 
  unable 
  to 
  continue 
  the 
  

   work 
  and 
  there 
  was 
  a 
  tantalizing 
  delay 
  in 
  the 
  apjiearance 
  of 
  the 
  

   second 
  volume, 
  which, 
  however, 
  was 
  very 
  quickly 
  followed 
  by 
  

   the 
  third, 
  and 
  in 
  the 
  preface 
  to 
  this 
  Dr. 
  Woodward 
  states 
  that 
  

   he 
  hopes 
  to 
  publish 
  the 
  fourth 
  and 
  concluding 
  volume, 
  containing 
  

   the 
  Mollusca, 
  Ascidia, 
  and 
  Cephalopoda, 
  at 
  tlie 
  end 
  of 
  the 
  year.
