  Natiea, 
  Conns, 
  and 
  Pyrula, 
  were 
  too 
  much 
  calcined 
  for 
  preservation. 
  

   This 
  author 
  also 
  found 
  microscopic 
  organisms 
  supposed 
  to 
  be 
  allied 
  

   to 
  Botalia 
  and 
  Miliolites 
  ; 
  and 
  Mr. 
  Sowerby 
  believed 
  that 
  he 
  could 
  

   identify 
  some 
  Cyprides. 
  The 
  limestones 
  often 
  contain 
  Corals, 
  and 
  

   M. 
  Hardie 
  considered 
  them 
  to 
  approach 
  mineralogically 
  to 
  the 
  

   limestones 
  of 
  the 
  Yicentin 
  ; 
  and 
  the 
  calcareous 
  sandstones, 
  both 
  in 
  

   mineralogical 
  characters 
  and 
  in 
  fossils, 
  to 
  the 
  Molasse 
  of 
  the 
  Bellu- 
  

   nois 
  (N. 
  Italy). 
  

  

  Dr. 
  Hochstetter 
  concludes 
  his 
  paper 
  on 
  the 
  Dutch 
  East 
  Indies, 
  

   already 
  noticed 
  (p. 
  47, 
  footnote), 
  with 
  some 
  general 
  remarks 
  upon 
  

   the 
  coal-formation 
  of 
  Borneo, 
  Sumatra, 
  and 
  Java. 
  He 
  remarks 
  that, 
  

   according 
  to 
  the 
  researches 
  of 
  Dr. 
  Herklots 
  and 
  Dr. 
  Goeppert, 
  there 
  

   is 
  scarcely 
  a 
  doubt 
  that 
  the 
  greatly 
  developed 
  Tertiary 
  beds 
  of 
  the 
  

   East 
  Indian 
  Archipelago 
  are 
  of 
  Eocene 
  age 
  ; 
  and 
  he 
  states 
  that 
  

   Mijnheer 
  P. 
  van 
  Dijk, 
  one 
  of 
  the 
  Mining 
  Engineers 
  of 
  the 
  Dutch 
  

   East 
  Indies, 
  has 
  arrived 
  at 
  the 
  same 
  conclusion, 
  and 
  has 
  published 
  a 
  

   paper 
  on 
  the 
  subject 
  in 
  a 
  number 
  of 
  the 
  ' 
  Natuurkundig 
  Tijdschrift 
  

   voor 
  Nederlandsch 
  Indie,' 
  of 
  which 
  I 
  have 
  not 
  been 
  able 
  to 
  find 
  a 
  

   copy 
  in 
  London. 
  

  

  Dr. 
  Hochstetter 
  himself 
  appears 
  to 
  coincide 
  in 
  this 
  opinion 
  ; 
  and 
  

   he 
  divides 
  the 
  whole 
  (so-called) 
  Eocene 
  formation 
  of 
  these 
  Islands 
  

   into 
  three 
  groups, 
  namely 
  — 
  

  

  1. 
  Lower 
  Group 
  : 
  coal-bearing; 
  containing 
  silicified 
  Wood, 
  but 
  

   few 
  or 
  no 
  marine 
  Shells. 
  

  

  2. 
  Middle 
  Group 
  : 
  a 
  calcareous 
  formation, 
  represented 
  in 
  Borneo 
  

   by 
  a 
  Nummulite-limestone, 
  and 
  in 
  Java 
  by 
  a 
  Coral-limestone 
  

   with 
  marine 
  Shells; 
  it 
  is 
  partly 
  contemporaneous, 
  perhaps, 
  

   with 
  the 
  next 
  group. 
  

  

  3. 
  Upper 
  Group 
  : 
  a 
  shale- 
  and 
  sandstone-formation, 
  very 
  rich 
  in 
  

   marine 
  Shells, 
  in 
  fossil 
  Plants 
  (described 
  by 
  Goeppert), 
  and 
  

   in 
  fossil 
  Resin. 
  

  

  Mijnheer 
  Herklots 
  does 
  not 
  attempt 
  to 
  give 
  the 
  probable 
  age 
  of 
  

   the 
  Echinoderms 
  from 
  Java 
  which 
  he 
  has 
  described 
  ; 
  but, 
  respecting 
  

   the 
  age 
  of 
  the 
  fossil 
  Plants, 
  Dr. 
  Goeppert, 
  after 
  enumerating 
  the 
  

   different 
  localities 
  in 
  Europe 
  in 
  which 
  Eocene 
  Plants 
  occur, 
  makes 
  

   the 
  following 
  remark: 
  — 
  " 
  Beyond 
  Europe 
  I 
  refer 
  to 
  this 
  period 
  the 
  

   Tertiary 
  flora 
  of 
  Java 
  discovered 
  by 
  Herr 
  Junghuhn, 
  and 
  which 
  I 
  

   have 
  just 
  investigated, 
  less 
  on 
  account 
  of 
  its 
  tropical 
  character 
  

   ****** 
  than 
  on 
  account 
  of 
  its 
  stratigraphical 
  position 
  beneath 
  

   a 
  marine 
  formation."* 
  

  

  Mijnheer 
  Junghuhn 
  obtained 
  fossil 
  Plants 
  from 
  three 
  localities, 
  as 
  

   stated 
  by 
  him 
  and 
  quoted 
  by 
  Dr. 
  Goeppert, 
  and 
  one 
  of 
  these 
  locali- 
  

   ties, 
  namely, 
  Selogambe, 
  is 
  in 
  the 
  same 
  district 
  as 
  Mount 
  Sela. 
  

  

  Continuing 
  the 
  comparison 
  of 
  this 
  district 
  with 
  the 
  Valley 
  of 
  the 
  

   Weald, 
  Mount 
  Sela 
  is 
  situated 
  close 
  to 
  the 
  northern 
  escarpment, 
  

   answering 
  to 
  our 
  North 
  Downs, 
  while 
  Selogambe 
  is 
  situated 
  south 
  

   of 
  the 
  central 
  axis, 
  about 
  midway 
  between 
  that 
  point 
  and 
  the 
  

   southern 
  escarpment, 
  and 
  almost 
  due 
  south 
  of 
  Mount 
  Sela 
  (see 
  wood- 
  

   cut, 
  p. 
  49). 
  It 
  is 
  probable, 
  therefore, 
  that 
  the 
  strata 
  at 
  Selogambe
