  Obituary. 
  

  

  and 
  as 
  editor 
  of 
  the 
  Monthly 
  Weather 
  Review, 
  also 
  acting 
  as 
  

   assistant 
  in 
  the 
  Records 
  Division. 
  In 
  July, 
  1891, 
  on 
  the 
  transfer 
  

   of 
  the 
  service 
  to 
  the 
  Department 
  of 
  Agriculture 
  he 
  was 
  appointed 
  

   one 
  of 
  the 
  professors 
  of 
  meteorology 
  in 
  the 
  Weather 
  Bureau, 
  where 
  

   he 
  was 
  at 
  once 
  assigned 
  to 
  regular 
  and 
  congenial 
  duties 
  in 
  the 
  

   Forecast 
  Division. 
  

  

  His 
  name 
  is 
  connected 
  with 
  the 
  " 
  Hazen 
  Thermometer 
  Shelter," 
  

   which 
  being 
  shown 
  to 
  be 
  better 
  than 
  the 
  large 
  close 
  double 
  louver 
  

   formerly 
  used, 
  was 
  adopted 
  by 
  the 
  Bureau 
  in 
  1885 
  and 
  still 
  

   remains 
  in 
  use. 
  His 
  experimental 
  work 
  with 
  the 
  sling 
  psychrome- 
  

   ter 
  and 
  dew-point 
  apparatus 
  was 
  executed 
  with 
  great 
  care 
  and 
  

   refinement, 
  but 
  the 
  resulting 
  psychrometer 
  formula 
  differs 
  from 
  

   those 
  in 
  current 
  use 
  in 
  that 
  it 
  rejects 
  the 
  important 
  term 
  depend- 
  

   ing 
  on 
  the 
  barometric 
  pressure. 
  Among 
  his 
  larger 
  publications 
  

   were 
  " 
  The 
  Reduction 
  of 
  Air 
  Pressure 
  to 
  Sea-level 
  " 
  and 
  " 
  The 
  

   Climate 
  of 
  Chicago." 
  In 
  addition 
  to 
  his 
  official 
  work 
  in 
  the 
  

   Weather 
  Bureau, 
  he 
  was 
  a 
  frequent 
  contributor 
  to 
  meteorological 
  

   and 
  other 
  scientific 
  journals. 
  He 
  was 
  one 
  of 
  the 
  supporters 
  of 
  

   "Science" 
  during 
  the 
  years 
  1882-85, 
  and 
  of 
  "The 
  American 
  

   Meteorological 
  Journal," 
  1884-96. 
  This 
  Journal, 
  between 
  1881 
  

   and 
  1887, 
  contained 
  a 
  number 
  of 
  papers 
  by 
  him. 
  He 
  also 
  pub- 
  

   lished, 
  independently, 
  works 
  entitled 
  "Meteorological 
  Tables" 
  

   and 
  " 
  The 
  Tornado." 
  

  

  Professor 
  Hazen 
  was 
  a 
  man 
  of 
  strong 
  convictions 
  and 
  thorough 
  

   sincerity 
  ; 
  he 
  had 
  an 
  indomitable 
  will, 
  abundant 
  energy 
  and 
  

   immense 
  powers 
  of 
  work. 
  His 
  tenacity 
  of 
  purpose, 
  independence 
  

   and 
  strength 
  of 
  feeling 
  may 
  have 
  made 
  him 
  at 
  times 
  appear 
  obsti- 
  

   nate 
  in 
  adhering 
  to 
  his 
  own 
  position 
  as 
  against 
  those 
  who 
  held 
  

   different 
  views, 
  but 
  his 
  character 
  was 
  true 
  and 
  his 
  amiable 
  and 
  

   lovable 
  disposition 
  he 
  showed 
  to 
  those 
  most 
  closely 
  associated 
  

   with 
  him. 
  His 
  sudden 
  death 
  is 
  a 
  great 
  loss 
  not 
  only 
  to 
  his 
  per- 
  

   sonal 
  friends, 
  but 
  to 
  the 
  Department 
  which 
  he 
  served 
  so 
  faithfully. 
  

  

  Dr. 
  Ha^ns 
  Beuno 
  Geinitz, 
  the 
  veteran 
  German 
  geologist, 
  

   died 
  at 
  Dresden 
  on 
  January 
  28th 
  in 
  his 
  eighty-sixth 
  year. 
  Half 
  

   a 
  century 
  has 
  passed 
  since 
  he 
  was 
  made 
  (1850) 
  Professor 
  of 
  

   Mineralogy 
  and 
  Geognosy 
  at 
  the 
  Polytechnic 
  School 
  in 
  Dresden 
  ; 
  

   a 
  little 
  earlier 
  (1846) 
  he 
  was 
  placed 
  in 
  charge 
  of 
  the 
  Dresden 
  

   Mineralogical 
  Museum, 
  of 
  which 
  he 
  later 
  (1857) 
  became 
  Director. 
  

   To 
  these 
  duties 
  he 
  devoted 
  himself 
  with 
  great 
  energy, 
  but 
  in 
  addi- 
  

   tion 
  he 
  was 
  ever 
  active, 
  nearly 
  to 
  the 
  close 
  of 
  his 
  long 
  life, 
  in 
  

   original 
  investigations 
  in 
  geology 
  and 
  paleontology, 
  and 
  the 
  list 
  

   of 
  his 
  publications 
  includes 
  many 
  and 
  valuable 
  papers; 
  the 
  first 
  of 
  

   these 
  bears 
  the 
  date 
  of 
  1839. 
  He 
  was 
  a 
  man 
  of 
  charming 
  per- 
  

   sonality, 
  alike 
  respected 
  by 
  his 
  scientific 
  colleagues 
  and 
  beloved 
  

   by 
  his 
  personal 
  friends. 
  

  

  Professor 
  David 
  E. 
  Hughes, 
  F.R.S., 
  the 
  English 
  physicist, 
  

   well 
  known 
  for 
  his 
  invention 
  of 
  a 
  widely-used 
  type-printing 
  tele- 
  

   graph 
  system, 
  also 
  for 
  his 
  work 
  in 
  connection 
  with 
  the 
  micro- 
  

   phone, 
  induction 
  balance 
  and 
  other 
  physical 
  instruments, 
  died 
  on 
  

   January 
  22d 
  at 
  the 
  age 
  of 
  sixty-eight 
  years.
