  allies. 
  These 
  intervals 
  may, 
  however, 
  be 
  due 
  to 
  breakage 
  before 
  

   being

  in 
  the

  Phosphatic 
  nodules. 
  (PI. 
  XXXVII, 
  fig. 
  6.) 
  

  

  Rounded 
  and 
  ovoid 
  nodules 
  of 
  a 
  pale 
  brown 
  colour 
  externally, 
  but 
  

   black 
  or 
  dark 
  brown 
  internally, 
  occur 
  with 
  these 
  fossils, 
  and 
  ap- 
  

   parently 
  at 
  almost 
  all 
  the 
  horizons 
  from 
  which 
  fossils 
  have 
  been 
  

   collected; 
  mostly 
  they 
  seem 
  to 
  have 
  been 
  free 
  in 
  the 
  clay, 
  but 
  

   sometimes 
  they 
  are 
  included 
  in 
  the 
  clay-ironstone. 
  These 
  nodules 
  

   vary 
  much 
  in 
  size, 
  some 
  being 
  less 
  than 
  an 
  inch 
  in 
  diameter, 
  others 
  

   3 
  or 
  4 
  inches 
  in 
  length 
  and 
  perhaps 
  2 
  inches 
  in 
  diameter. 
  Thin 
  

   sections 
  under 
  the 
  microscope 
  show 
  for 
  the 
  most 
  part 
  a 
  mass 
  of 
  fine 
  

   debris 
  with 
  nothing 
  definable 
  ; 
  but 
  some 
  specimens 
  show 
  in 
  parts 
  

   small 
  masses 
  of 
  minute 
  oval 
  bodies, 
  with 
  a 
  long 
  diameter 
  of 
  1 
  mm., 
  

   which 
  agree 
  in 
  form 
  and 
  size 
  with 
  the 
  small 
  coprolites 
  described 
  

   by 
  Mr. 
  A. 
  Strahan 
  1 
  from 
  the 
  Phosphatic 
  Chalk 
  of 
  Taplow, 
  and 
  

   indeed 
  there 
  can 
  be 
  little 
  doubt 
  that 
  they 
  are 
  the 
  droppings 
  of 
  some 
  

   small 
  animal. 
  And 
  further, 
  upon 
  closer 
  examination 
  with 
  the 
  

   microscope, 
  these 
  minute 
  ovoid 
  bodies 
  may 
  be 
  seen 
  pressed 
  closer 
  

   and 
  closer 
  together, 
  until 
  at 
  last 
  they 
  form 
  one 
  mass 
  ; 
  but 
  in 
  most 
  

   cases 
  the 
  separate 
  pellets 
  may 
  be 
  still 
  distinguished. 
  A 
  number 
  of 
  

   these 
  nodules 
  have 
  been 
  tested, 
  and 
  in 
  all 
  cases 
  they 
  proved 
  to 
  be 
  

   rich 
  in 
  tricalcic 
  phosphate. 
  

  

  The 
  following 
  forms 
  have 
  been 
  identified 
  from 
  this

  Precisely 
  similar 
  forms 
  have 
  been 
  found 
  in 
  the 
  talus 
  at 
  other 
  

   points 
  near 
  Elmwood, 
  and 
  on 
  the 
  side 
  of 
  a 
  glacier-slope 
  at 
  the 
  

   western 
  point 
  of 
  Cape 
  Flora. 
  

  

  This 
  series 
  of 
  fossils, 
  although 
  small, 
  is 
  of 
  the 
  greatest 
  interest, 
  

   inasmuch 
  as 
  it 
  contains 
  ammonites 
  which 
  give 
  no 
  uncertain 
  indica- 
  

   tion 
  of 
  the 
  horizon 
  to 
  which 
  they 
  must 
  be 
  referred. 
  Ammonites 
  

   modiolaris 
  is 
  distinctly 
  a 
  Kellaways 
  Hock 
  form, 
  although 
  extending 
  

   into 
  the 
  true 
  Oxford 
  Clay. 
  The 
  occurrence 
  with 
  this 
  of 
  A. 
  macro- 
  

   cephalus, 
  which 
  not 
  only 
  occurs 
  in 
  the 
  lowest 
  Oxford 
  Clay 
  and 
  

   Kellaways 
  Rock, 
  but 
  is 
  perhaps 
  the 
  most 
  characteristic 
  ammonite 
  of 
  

   the 
  Cornbrash, 
  shows 
  very 
  clearly 
  that 
  beds 
  of 
  lowest 
  Oxfordian 
  

   age 
  occur 
  at 
  Cape 
  Plora 
  at 
  a 
  height 
  of 
  about 
  400 
  or 
  500 
  feet 
  above 
  

   the 
  sea, 
  and 
  doubtless 
  correspond 
  to 
  some 
  extent 
  with 
  the 
  ' 
  macro- 
  

   cephalus-he&s 
  ' 
  which 
  are 
  now 
  known 
  to 
  have 
  so 
  vast 
  an 
  extent 
  

   throughout 
  the 
  northern 
  hemisphere, 
  if, 
  indeed, 
  they 
  do 
  not 
  also 
  

   occur 
  in 
  Australia 
  (see 
  references
