  — 
  Ten 
  accessions 
  pertaining 
  to 
  minerals— 
  a 
  1,842-gram 
  in- 
  

   dividual 
  of 
  the 
  Harrisonville, 
  Mo., 
  meteorite, 
  and 
  nine 
  slices 
  of 
  meteor- 
  

   ites—were 
  added 
  by 
  purchase 
  through 
  the 
  income 
  from 
  the 
  Roebling 
  

   fund. 
  The 
  largest 
  single 
  accession 
  of 
  minerals 
  was 
  the 
  gift 
  of 
  the 
  

   John 
  W. 
  Langsdale 
  collection, 
  including 
  many 
  good 
  examples 
  from 
  

   old 
  American 
  and 
  European 
  localities. 
  The 
  outstanding 
  addition 
  to 
  

   the 
  gem 
  collection 
  was 
  the 
  316-carat 
  star 
  sapphire 
  known 
  as 
  Star 
  of 
  

   Artaban. 
  This 
  beautiful 
  stone 
  ranks 
  with 
  the 
  finest 
  of 
  the 
  Museum's 
  

   individual 
  gems. 
  Another 
  notable 
  gem 
  stone 
  was 
  a 
  54-carat 
  blue 
  

   Brazilian 
  topaz 
  obtained 
  through 
  the 
  Frances 
  Lea 
  Chamberlain 
  fund. 
  

   Dr. 
  Stuart 
  H. 
  Perry, 
  associate 
  in 
  mineralogy, 
  presented 
  an 
  album 
  of 
  

   five 
  volumes 
  containing 
  approximately 
  1,500 
  photomicrographs 
  of 
  the 
  

   structure 
  in 
  meteoric 
  irons, 
  which, 
  with 
  the 
  negatives 
  received 
  from 
  

   Dr. 
  Perry 
  last 
  year, 
  has 
  resulted 
  in 
  the 
  most 
  complete 
  file 
  of 
  the 
  metal- 
  

   lurgy 
  of 
  meteoric 
  irons 
  in 
  existence. 
  Dr. 
  Perry 
  also 
  donated 
  a 
  4,640- 
  

   gram 
  specimen 
  of 
  the 
  Modoc, 
  Kans., 
  meteorite. 
  

  

  The 
  most 
  important 
  additions 
  to 
  the 
  collections 
  of 
  invertebrate 
  pale- 
  

   ontology 
  and 
  paleobotany 
  were 
  the 
  Devonian 
  invertebrates 
  collected 
  

   in 
  the 
  Mississippi 
  Valley 
  States 
  by 
  Prof. 
  A. 
  S. 
  Warthin, 
  Jr., 
  and 
  

   Dr. 
  G. 
  A. 
  Cooper. 
  In 
  return 
  for 
  assistance 
  by 
  Dr. 
  C. 
  E. 
  Resser, 
  

   Dr. 
  Franco 
  Rasetti, 
  of 
  Laval 
  University, 
  presented 
  a 
  splendid 
  set 
  of 
  

   fossils 
  and 
  casts 
  of 
  types 
  from 
  the 
  classic 
  locality 
  at 
  Levis, 
  opposite 
  

   Quebec 
  City, 
  Canada. 
  The 
  income 
  from 
  the 
  Springer 
  fund 
  provided 
  

   12 
  Devonian 
  crinoids 
  from 
  Ontario, 
  one 
  of 
  the 
  most 
  important 
  ac- 
  

   cessions 
  of 
  the 
  year 
  to 
  the 
  collection 
  of 
  fossil 
  echinoderms. 
  A 
  col- 
  

   lection 
  of 
  about 
  2,000 
  Triassic 
  fossils 
  from 
  Nevada 
  will 
  undoubtedly 
  

   include 
  many 
  types 
  when 
  the 
  study 
  of 
  these 
  fossils 
  has 
  been 
  completed. 
  

   Among 
  the 
  accessions 
  recorded 
  in 
  the 
  section 
  of 
  Cenozoic 
  inverte- 
  

   brates 
  were 
  topotypes 
  of 
  the 
  f 
  oraminifer 
  Pseudophragmina 
  (Porporo- 
  

   cyclina) 
  peruviana 
  and 
  holotype 
  and 
  paratypes 
  of 
  the 
  foraminifer 
  

   Paranonion 
  venezuelanum.
