  The 
  last 
  scientific 
  work 
  of 
  Stoliczka, 
  whose 
  name 
  will 
  be 
  always 
  

   associated 
  with 
  the 
  palaeontology 
  of 
  India, 
  was 
  performed 
  during 
  the 
  

   return 
  of 
  the 
  second 
  Yarkand 
  expedition. 
  A 
  few 
  days 
  before 
  his 
  

   death 
  he 
  crossed 
  the 
  Karakoram 
  Pass, 
  and, 
  travelling 
  on, 
  traversed 
  

   the 
  last 
  geological 
  scene 
  he 
  ever 
  described. 
  He 
  wrote 
  in 
  his 
  jour- 
  

   nal 
  : 
  — 
  " 
  At 
  last 
  we 
  descended 
  into 
  a 
  narrow 
  gorge, 
  the 
  sides 
  of 
  

   which, 
  for 
  fully 
  a 
  mile, 
  consisted 
  of 
  a 
  limestone 
  conglomerate, 
  the 
  

   boulders 
  of 
  white, 
  grey, 
  or 
  black 
  limestone 
  being 
  well 
  rounded 
  and 
  

   worn, 
  and 
  cemented 
  together 
  by 
  a 
  stiff 
  bright 
  red 
  clay. 
  Upon 
  this 
  

   followed 
  dolomitic 
  limestones, 
  rather 
  indifferently 
  bedded, 
  massive 
  and 
  

   white 
  ; 
  and 
  these 
  were 
  overlain 
  by 
  bluish 
  shales 
  and 
  well-bedded 
  

   limestones 
  extending 
  from 
  about 
  six 
  miles 
  north 
  of 
  Burtri 
  to 
  the 
  

   camp. 
  The 
  limestones 
  appear 
  to 
  be 
  Triassic 
  ; 
  they 
  are 
  compact, 
  

   with 
  layers 
  full 
  of 
  small 
  (iasteropods, 
  among 
  which 
  I 
  noticed 
  a 
  

   Nerincea. 
  The 
  so-called 
  ' 
  Karakoram 
  stones 
  ' 
  occur 
  in 
  dark 
  shales 
  

   below 
  the 
  limestones, 
  which 
  are 
  capped 
  by 
  a 
  yellowish-brown 
  lime- 
  

   stone, 
  well 
  bedded, 
  but 
  of 
  unascertained 
  age. 
  The 
  whole 
  series 
  dips 
  

   north-west 
  at 
  a 
  moderate 
  angle 
  "*. 
  

  

  It 
  is 
  to 
  a 
  group 
  of 
  the 
  Karakoram 
  stones 
  that 
  I 
  venture 
  to 
  draw 
  

   the 
  attention 
  of 
  the 
  Society. 
  

  

  The 
  stratigraphical 
  position 
  of 
  the 
  stones 
  is 
  lower 
  than 
  the 
  Lias 
  ; 
  

   and 
  they 
  may 
  be 
  Rhaetic 
  or 
  Triassic 
  in 
  age. 
  

  

  The 
  stones 
  had 
  been 
  objects 
  of 
  curiosity 
  in 
  India 
  for 
  many 
  years 
  

   before 
  their 
  exact 
  locality 
  was 
  discovered 
  ; 
  and 
  their 
  spherical 
  and 
  

   spheroidal 
  shapes 
  had 
  attracted 
  much 
  attention. 
  A 
  specimen 
  was 
  

   given 
  to 
  this 
  Society 
  many 
  years 
  ago 
  by 
  Col. 
  Godwin-Austen, 
  P.R.S., 
  

   and 
  is 
  in 
  our 
  museum. 
  No 
  careful 
  examination 
  of 
  any 
  of 
  the 
  nu- 
  

   merous 
  forms 
  of 
  the 
  spherical 
  stones 
  was 
  made, 
  however 
  ; 
  and 
  in 
  

   1878, 
  Mr. 
  W. 
  T. 
  Blanford, 
  P.R.S., 
  asked 
  me 
  to 
  investigate 
  the 
  fossils, 
  

   and 
  to 
  write 
  their 
  description 
  in 
  a 
  memoir, 
  which 
  was 
  to 
  be 
  included 
  

   in 
  the 
  •' 
  Scientific 
  Results 
  of 
  the 
  Second 
  Yarkand 
  Mission.' 
  My 
  work 
  

   was 
  completed 
  and 
  the 
  book 
  was 
  published 
  in 
  1879. 
  

  

  The 
  Karakoram 
  stones 
  were, 
  after 
  as 
  careful 
  an 
  examination 
  as 
  I 
  

   could 
  give 
  them, 
  placed 
  in 
  the 
  class 
  Rhizopoda, 
  in 
  a 
  new 
  order, 
  the 
  

   Syringosphaeridse 
  ; 
  and 
  the 
  typical 
  form 
  was 
  placed 
  in 
  a 
  genus 
  Syrin- 
  

   gosphceria. 
  Five 
  well-marked 
  species 
  were 
  described 
  as 
  belonging 
  

   to 
  this 
  genus. 
  

  

  A 
  very 
  large 
  specimen, 
  the 
  only 
  one 
  of 
  its 
  kind, 
  was 
  not 
  cut 
  into 
  ; 
  

   nor 
  were 
  microscopic 
  preparations 
  made 
  of 
  it. 
  But 
  subsequently,
