  rotundus 
  (Smith

  from 
  

   the 
  Phosphate 
  beds 
  of 
  South 
  Carolina 
  is 
  a 
  very 
  much 
  shorter, 
  

   wider 
  and 
  more 
  rapidly 
  pointed 
  form. 
  

  

  In 
  addition

  the 
  foregoing 
  Yan 
  Benedenf 
  has 
  described 
  a 
  

   number 
  of 
  rostra 
  under 
  different 
  generic 
  names 
  including 
  a 
  

   somewhat 
  similar 
  but 
  larger 
  and 
  otherwise 
  different 
  form 
  

   which 
  he 
  calls 
  Brachyrhynchus 
  teretrirostris 
  (Rutimever) 
  and 
  

   which 
  occurs 
  in 
  the 
  Mio

  Belgium,

  (Yan

   Belgium 
  is 
  somewhat 
  similar 
  to 
  the

  form

  more 
  

   depressed

   the

  is 
  also 
  somewhat 
  similar,

   shows 
  five 
  nutrient

  While 
  making 
  a 
  microscopic 
  study 
  of 
  minerals 
  the 
  author 
  

   found 
  in 
  the 
  Museum 
  of 
  the 
  University 
  of 
  California 
  a 
  speci- 
  

   men 
  labelled 
  " 
  Wollastonite, 
  St. 
  Inez, 
  Calif.," 
  whose 
  optical 
  

   properties 
  are 
  different 
  from 
  those 
  of 
  wollastonite, 
  pectolite, 
  

   and 
  all 
  other 
  known 
  minerals. 
  The 
  mineral 
  proved 
  to 
  be 
  a 
  

   new 
  species 
  and 
  the 
  name 
  eakleite 
  (pronounced 
  ake-el-ite) 
  is 
  

   proposed 
  for 
  it, 
  after 
  the 
  mineralogist 
  Prof. 
  Arthur 
  S. 
  Eakle. 
  

  

  The 
  largest 
  piece 
  of 
  eakleite 
  in 
  the 
  collection 
  is 
  about 
  three 
  

   centimeters 
  across 
  ; 
  it 
  is 
  free 
  from 
  foreign 
  material 
  and 
  is 
  

   made 
  up 
  of 
  successive, 
  irregular 
  layers 
  of 
  fibers, 
  some 
  of 
  these 
  

   layers 
  several 
  millimeters 
  across. 
  It 
  is 
  compact, 
  very 
  tough, 
  

   and 
  has 
  a 
  hardness 
  of 
  about 
  6-J-. 
  A 
  specific 
  gravity

   ment 
  on 
  a 
  large 
  fragment 
  with 
  a 
  balance

  2*705 
  and 
  one 
  

   made 
  by 
  suspending 
  in 
  Thoulet 
  solution 
  gave 
  2*685. 
  Eakleite 
  

   fuses 
  at 
  about 
  25 
  with 
  slight 
  boiling 
  to 
  a 
  glassy, 
  somewhat 
  

   vesicular 
  globule 
  ; 
  it 
  loses 
  its 
  water 
  only 
  at 
  a 
  high 
  heat. 
  It 
  is 
  

   easily 
  soluble 
  in 
  acid 
  with 
  separation 
  of 
  flaky 
  silica 
  but 
  without 
  

   gelatinization.
