  take 
  the 
  place 
  of 
  the 
  earlier 
  Meteoro- 
  

   logical 
  Tables 
  of 
  Dr. 
  Arnold 
  Guyot, 
  the 
  fourth 
  and 
  last 
  edition 
  

   of 
  which 
  was 
  issued 
  in 
  1884. 
  The 
  appearance 
  in 
  1893 
  of 
  the 
  first 
  

   volume 
  of 
  this 
  new 
  series, 
  which 
  is 
  devoted 
  to 
  Meteorological 
  

   Tables, 
  was 
  then 
  announced 
  in 
  this 
  Journal 
  (vol. 
  xlvi, 
  160) 
  ; 
  the 
  

   third 
  volume, 
  still 
  to 
  come, 
  is 
  to 
  include 
  Physical 
  Tables. 
  The 
  

   volume 
  now 
  issued 
  contains 
  105 
  pages 
  of 
  introductory 
  matter, 
  

   giving 
  useful 
  formulas, 
  discussion 
  of 
  mensuration, 
  units, 
  geodesy, 
  

   astronomy, 
  etc. 
  Then 
  follow 
  forty-two 
  tables, 
  chiefly 
  geograph- 
  

   ical 
  in 
  object, 
  and 
  finally 
  the 
  work 
  closes 
  with 
  the 
  Appendix 
  giv- 
  

   ing 
  the 
  relations 
  of 
  units, 
  prepared 
  by 
  the 
  late 
  Mr. 
  G. 
  E. 
  Curtis 
  

   for 
  the 
  earlier 
  meteorological 
  volume.

  Obituary. 
  

  

  Dr. 
  George 
  A. 
  Rex. 
  — 
  Dr. 
  Rex, 
  of 
  Philadelphia 
  died 
  suddenly 
  

   on 
  the 
  fourth 
  of 
  February 
  last. 
  The 
  following 
  paragraphs 
  are 
  

   from 
  the 
  Proceedings 
  of 
  the 
  Academy 
  of 
  Natural 
  Sciences 
  of 
  

   Philadelphia, 
  of 
  which 
  he 
  was 
  a 
  member. 
  

  

  Dr. 
  Rex 
  was 
  the 
  highest 
  authority 
  on 
  the 
  Myxomycetes 
  in 
  the 
  

   United 
  States. 
  It 
  was 
  his 
  enthusiastic 
  study 
  of 
  this 
  group 
  that 
  

   first 
  brought 
  him 
  to 
  the 
  Section, 
  and 
  his 
  communications 
  on 
  this 
  

   subject 
  formed 
  an 
  interesting 
  part 
  of 
  nearly 
  every 
  meeting. 
  He 
  

   was 
  the 
  author 
  of 
  numerous 
  species, 
  which, 
  owing 
  to 
  his 
  extreme 
  

   conservatism, 
  will 
  doubtless 
  continue 
  to 
  bear 
  his 
  name. 
  Many 
  

   forms, 
  new 
  to 
  him, 
  remained 
  in 
  his 
  collection 
  unnamed 
  for 
  years, 
  

   and 
  were 
  only 
  published 
  when 
  he 
  had 
  thoroughly 
  convinced 
  him- 
  

   self 
  that 
  they 
  were 
  really 
  new 
  to 
  science. 
  

  

  Although 
  he 
  was 
  interested 
  principally 
  in 
  the 
  Myxomycetes, 
  he 
  

   was 
  an 
  earnest 
  student 
  of 
  the 
  lower 
  orders 
  of 
  Fungi 
  and 
  an 
  ardent 
  

   admirer 
  of 
  everything 
  beautiful 
  in 
  microscopic 
  nature. 
  

  

  Recent 
  deaths 
  abroad 
  are 
  the 
  following 
  : 
  Marquis 
  de 
  Saporta, 
  

   the 
  eminent 
  botanist, 
  at 
  Aix 
  ; 
  Professor 
  Heinrich 
  Wild, 
  of 
  St. 
  

   Petersburg, 
  well 
  known 
  for 
  his 
  researches 
  in 
  magnetism 
  and 
  

   optics; 
  Dr. 
  Alfred 
  W. 
  Stelzj^er, 
  Professor 
  of 
  Geology 
  at 
  

   Freiberg, 
  on 
  February 
  25th.
