  The 
  Jubilee 
  Number 
  of 
  Nature. 
  — 
  On 
  November 
  4, 
  1869, 
  

   fifty 
  years 
  ago, 
  the 
  first 
  number 
  of 
  the 
  new 
  weekly 
  journal 
  of 
  

   science, 
  Nature, 
  was 
  published. 
  It 
  is 
  very 
  interesting 
  that 
  the 
  

   history 
  of 
  this 
  undertaking 
  with 
  the 
  details 
  of 
  the 
  original 
  plan 
  

   should 
  be 
  now 
  1 
  presented 
  by 
  the 
  founder, 
  Sir 
  Norman 
  Lockyer, 
  

   a 
  gentleman 
  to 
  whom 
  science 
  owes 
  much 
  in 
  many 
  directions. 
  It 
  

   is 
  fitting, 
  also, 
  that 
  number 
  XLI 
  of 
  the 
  series 
  of 
  Scientific 
  Wor- 
  

   thies, 
  which 
  have 
  been 
  published 
  from 
  time 
  to 
  time 
  by 
  Nature, 
  

   should 
  be 
  given 
  to 
  him 
  (pp. 
  191-195) 
  ; 
  this 
  notice, 
  by 
  M. 
  Des- 
  

   landres 
  of 
  the 
  Meudon 
  Observatory, 
  is 
  accompanied 
  by 
  an 
  

   admirable 
  portrait. 
  During 
  the 
  past 
  fifty 
  years, 
  Nature 
  has 
  

   won 
  for 
  itself 
  a 
  unique 
  place 
  among 
  the 
  scientific 
  publications 
  

   of 
  the 
  world, 
  and 
  it 
  is 
  remarkable, 
  notwithstanding 
  the 
  growth 
  

   of 
  science, 
  that 
  the 
  plan 
  originally 
  adopted 
  should 
  be 
  almost 
  

   identical 
  in 
  its 
  details 
  with 
  that 
  being 
  carried 
  out 
  to-day. 
  On 
  

   the 
  other 
  hand, 
  the 
  departments 
  of 
  scientific 
  activity 
  have 
  multi- 
  

   plied 
  far 
  beyond 
  what 
  anyone 
  could 
  have 
  anticipated 
  in 
  1869. 
  

   This 
  is 
  well 
  brought 
  out 
  by 
  the 
  series 
  of 
  chapters, 
  about 
  40 
  in 
  

   number, 
  written 
  by 
  various 
  specialists. 
  Conspicuous 
  among 
  the 
  

   newer 
  developments 
  of 
  science 
  here 
  presented 
  are 
  those 
  dealing 
  

   with 
  the 
  properties 
  of 
  gases 
  and 
  the 
  structure 
  of 
  matter, 
  includ- 
  

   ing 
  radium 
  and 
  the 
  electron, 
  and 
  the 
  ionization 
  of 
  gases. 
  The 
  

   four 
  chapters 
  devoted 
  to 
  these 
  subjects 
  are, 
  respectively, 
  by 
  

   Sir 
  J. 
  J. 
  Thomson, 
  Sir 
  Ernest 
  Rutherford, 
  Professor 
  Frederick 
  

   Soddy, 
  and 
  Professor 
  J. 
  S. 
  Townsend. 
  Many 
  other 
  subjects 
  

   included 
  might 
  also 
  be 
  mentioned 
  as 
  marking 
  the 
  progress 
  of 
  

   science 
  during 
  the 
  past 
  half 
  -century, 
  indeed 
  the 
  entire 
  number 
  

   should 
  be 
  read 
  by 
  all 
  interested 
  in 
  learning 
  the 
  main 
  facts 
  as 
  to 
  

   what 
  science 
  has 
  accomplished 
  in 
  this 
  period. 
  It 
  is 
  also 
  note- 
  

   worthy 
  that 
  four 
  of 
  the 
  writers, 
  whose 
  chapters 
  in 
  this 
  number 
  

   are 
  somewhat 
  longer 
  and 
  more 
  comprehensive 
  than 
  most 
  of 
  the 
  

   others, 
  were 
  contributors 
  to 
  the 
  earliest 
  issues 
  of 
  this 
  journal. 
  

   They 
  are 
  : 
  Sir 
  Archibald 
  Geikie, 
  Sir 
  E. 
  Eay 
  Lankaster, 
  Profes- 
  

   sor 
  Bonney 
  and 
  Canon 
  Wilson. 
  The 
  service 
  rendered 
  by 
  Nature 
  

   to 
  the 
  science 
  of 
  the 
  world 
  is 
  so 
  well 
  recognized 
  as 
  to 
  call 
  for 
  no 
  

   further 
  notice 
  in 
  this 
  place; 
  it 
  is 
  now, 
  as 
  it 
  has 
  been 
  from 
  the 
  

   beginning, 
  the 
  model 
  of 
  a 
  weekly 
  scientific 
  periodical. 
  

  

  The 
  issue 
  following 
  the 
  Jubilee 
  Number, 
  that 
  for 
  November 
  

   13, 
  is 
  appropriately 
  devoted 
  in 
  part 
  (pp. 
  281-295) 
  to 
  the 
  many
