  Doctor 
  Walcott

  every

  a 
  worthy 
  

   successor 
  to 
  the 
  three

  WILLIAM 
  HEALEY 
  DALL 
  

  

  William 
  Healey 
  Dall, 
  honorary 
  curator 
  of 
  mollusks 
  in 
  the 
  National 
  

   Museum 
  since 
  1880, 
  died 
  on 
  March 
  27, 
  1927. 
  He 
  was 
  born 
  in 
  Boston, 
  

   August 
  21, 
  1845, 
  and 
  became 
  interested 
  in 
  the 
  study 
  of 
  shells 
  at 
  a 
  

   very 
  early 
  age. 
  This 
  study 
  he 
  cultivated 
  at 
  every 
  possible 
  oppor- 
  

   tunity, 
  with 
  the 
  result 
  that 
  after 
  a 
  long 
  and 
  active 
  career 
  he 
  was 
  

   known 
  at 
  the 
  time 
  of 
  his 
  death 
  as 
  America's 
  leading 
  conchologist, 
  

   His 
  lesearches 
  were 
  not 
  confined 
  to 
  that 
  subject, 
  however, 
  and 
  he 
  pub- 
  

   lished 
  noteworthy 
  contributions 
  to 
  paleontology, 
  zoology, 
  meteor- 
  

   ology, 
  and 
  nomenclature. 
  He 
  was, 
  in 
  fact, 
  one 
  of 
  the 
  last 
  survivors 
  

   of 
  the 
  old 
  school 
  of 
  " 
  all-around 
  " 
  naturalists, 
  which 
  has 
  practically 
  

   disappeared 
  in 
  this 
  day 
  of 
  ultra-specialization. 
  

  

  In 
  1865 
  Doctor 
  Dall 
  was 
  put 
  in 
  charge 
  of 
  the 
  scientific 
  work 
  of 
  

   the 
  International 
  Telegraph 
  Expedition 
  to 
  Alaska, 
  which 
  resulted 
  

   in 
  his 
  exhaustive 
  volume 
  on 
  "Alaska 
  and 
  its 
  Resources," 
  which 
  for 
  

   many 
  years 
  was 
  the 
  standard 
  work 
  on 
  Alaska. 
  In 
  1871 
  he 
  joined 
  

   the 
  United 
  States 
  Coast 
  Survey 
  and 
  continued 
  his 
  studies 
  in 
  Alaska, 
  

   publishing 
  an 
  account 
  of 
  the 
  meteorology 
  of 
  the 
  region 
  and 
  a 
  work 
  

   entitled 
  " 
  The 
  Coast 
  Pilot 
  of 
  Alaska." 
  In 
  1884 
  he 
  was 
  appointed 
  a 
  

   paleontologist 
  of 
  the 
  United 
  States 
  Geological 
  Survey, 
  which 
  posi- 
  

   tion 
  he 
  filled 
  until 
  his 
  death, 
  holding 
  at 
  the 
  same 
  time 
  his 
  honorary 
  

   title 
  in 
  the 
  National 
  Museum. 
  During 
  this 
  period 
  he 
  produced 
  hun- 
  

   dreds 
  of 
  monographs 
  and 
  smaller 
  papers, 
  chiefly 
  dealing 
  with 
  his 
  

   specialty, 
  mollusks. 
  Doctor 
  Dall's 
  work 
  was 
  recognized 
  internation- 
  

   ally 
  by 
  election 
  to 
  American 
  and 
  foreign 
  learned 
  societies 
  and 
  by 
  

   many 
  honorary 
  degrees.

  Frank 
  Hall 
  Knowlton, 
  custodian 
  of 
  Mesozoic 
  plants 
  in 
  the 
  National 
  

   Museum, 
  died 
  at 
  his 
  home 
  in 
  Ballston, 
  Va., 
  November 
  22, 
  1926. 
  

   Doctor 
  Knowlton's 
  first 
  association 
  with 
  the 
  Institution 
  was 
  just 
  after 
  

   his 
  graduation 
  from 
  college, 
  when 
  he 
  worked 
  in 
  the 
  Smithsonian 
  

   taxidermy 
  shop. 
  Later 
  he 
  was 
  appointed 
  aid, 
  and 
  then 
  assistant 
  

   curator, 
  in 
  botany, 
  with 
  charge 
  of 
  the 
  herbarium, 
  the 
  modest 
  be- 
  

   ginnings 
  of 
  the 
  present 
  great 
  National 
  Herbarium. 
  At 
  this 
  time 
  

   he 
  began 
  his 
  work 
  on 
  fossil 
  plants, 
  and 
  in 
  1889 
  was 
  appointed 
  an 
  as- 
  

   sistant 
  paleontologist 
  in 
  the 
  United 
  States 
  Geological 
  Survey. 
  He 
  

   remained 
  with 
  the 
  survey 
  until 
  his 
  death, 
  at 
  the 
  same 
  time 
  retaining 
  

   his 
  honorary 
  position 
  with 
  the 
  National 
  Museum.
