  ON 
  THE 
  

  

  bed 
  of 
  " 
  coprolites 
  " 
  be 
  considered 
  sufficient 
  proof. 
  I 
  think 
  there- 
  

   fore 
  that 
  the 
  statement 
  mentioned 
  with 
  some 
  degree 
  of 
  doubt 
  by 
  

   Judd 
  in 
  the 
  text 
  of 
  his 
  first 
  paper 
  *, 
  but 
  brought 
  more 
  prominently 
  

   forward 
  in 
  the 
  "Comparative 
  Table 
  " 
  of 
  a 
  later 
  paper 
  t, 
  whence 
  it 
  

   has 
  made 
  its 
  appearance 
  in 
  other 
  quarters 
  j, 
  should 
  be 
  set 
  aside 
  as 
  

   against 
  the 
  evidence. 
  

  

  That 
  the 
  Coprolite-bed 
  should 
  have 
  been 
  traced 
  by 
  Leckenby 
  so 
  

   far 
  north 
  as 
  Hunmanby 
  Gap 
  shows 
  that 
  the 
  average 
  dip 
  of 
  the 
  beds 
  

   is 
  not 
  great 
  — 
  not 
  perhaps 
  greater 
  than 
  that 
  of 
  the 
  chalk 
  — 
  and 
  that 
  

   the 
  breadth 
  of 
  the 
  outcrop 
  of 
  the 
  bituminous 
  shales 
  cannot 
  be 
  taken 
  

   as 
  evidence 
  of 
  their 
  thickness. 
  They 
  are 
  probably 
  repeated 
  over 
  

   and 
  over 
  again 
  in 
  the 
  contortions. 
  And 
  as 
  there 
  are 
  strong 
  reasons 
  

   for 
  believing 
  that 
  the 
  shales 
  seen 
  in 
  the 
  cliff 
  near 
  Filey, 
  which 
  have 
  

   been 
  supposed 
  to 
  represent 
  lower 
  beds 
  (" 
  Middle 
  Kimeridge 
  " 
  and, 
  

   on 
  the 
  shore, 
  " 
  Lower 
  Kimeridge 
  "), 
  are 
  not 
  in 
  place

  § 
  Judd 
  (op. 
  cit. 
  pp. 
  239 
  & 
  240) 
  describes 
  beds 
  of 
  sandy 
  blue 
  clay 
  seen 
  in 
  the 
  

   cliff 
  about 
  a 
  mile 
  to 
  the 
  south 
  of 
  Filey 
  (i. 
  e., 
  about 
  three 
  miles 
  north 
  of 
  Speeton) 
  

   under 
  the 
  title 
  of 
  Middle 
  Kimeridge, 
  and 
  seems 
  to 
  have 
  regarded 
  them 
  as 
  in 
  

   place. 
  Phillips, 
  however, 
  refers 
  to 
  them 
  as 
  making 
  " 
  slight 
  appearances 
  at 
  

   several 
  detached 
  points 
  in 
  and 
  under 
  the 
  drift 
  " 
  (Geol. 
  of 
  Yorkshire, 
  3rd 
  ed. 
  

   pt. 
  i. 
  p. 
  103). 
  

  

  I 
  have 
  made 
  careful 
  examinations 
  of 
  these 
  beds 
  at 
  intervals 
  during 
  several 
  

   years, 
  but 
  have 
  not 
  yet 
  succeeded 
  in 
  finding 
  any 
  of 
  the 
  Secondaries 
  in 
  place. 
  

   The 
  huge 
  masses 
  of 
  shale 
  which 
  occur 
  here 
  at 
  the 
  base 
  of 
  the 
  cliff 
  and 
  on 
  the 
  upper 
  

   portion 
  of 
  the 
  shore 
  (the 
  lower 
  part 
  of 
  the 
  shore 
  I 
  have 
  not 
  yet 
  seen 
  exposed 
  

   here) 
  are 
  all 
  (i 
  boulclered 
  " 
  in 
  the 
  Basement 
  Clay, 
  the 
  lowest 
  boulder-clay 
  of 
  the 
  

   coast, 
  one 
  of 
  whose 
  characteristics 
  is 
  the 
  frequent 
  inclusion 
  of 
  masses 
  of 
  this 
  kind.

  These 
  "boulders" 
  when 
  they 
  reach 
  down 
  to 
  the 
  shore-line 
  might 
  

   sometimes 
  be 
  supposed 
  to 
  underlie 
  the 
  drift, 
  but 
  when 
  the 
  beach 
  is 
  removed 
  

   at 
  the 
  cliff-foot 
  the 
  boulder-clay 
  is 
  seen 
  to 
  pass 
  under 
  them. 
  They 
  are 
  generally 
  

   lenticular 
  in 
  shape, 
  and 
  some 
  of 
  them, 
  with 
  the 
  bedding 
  still 
  preserved, 
  are 
  

   tilted 
  nearly 
  on 
  end, 
  and 
  run 
  up 
  into 
  the 
  drifts 
  for 
  30 
  or 
  40 
  feet 
  above 
  high- 
  

   water 
  mark. 
  The 
  most 
  conclusive 
  and 
  convincing 
  proof 
  of 
  their 
  transportation 
  

   is 
  furnished 
  by 
  the 
  fossils 
  with 
  which 
  most 
  of 
  them 
  abound. 
  I 
  have 
  collected 
  

   the 
  following 
  species 
  from 
  masses 
  of 
  shale 
  which 
  lay 
  in 
  the 
  cliff-foot 
  with 
  un- 
  

   interrupted 
  bedding-planes 
  :

  This 
  list 
  shows 
  that 
  the 
  masses 
  from 
  which 
  I 
  obtained 
  the 
  fossils 
  have 
  been 
  

   derived 
  from 
  the 
  Jamesoni-beds 
  of 
  the 
  Lias, 
  with 
  which 
  they 
  agree 
  well 
  in 
  physical 
  

   character. 
  

  

  Of 
  course 
  other 
  masses 
  may 
  have 
  come 
  from 
  different 
  horizons, 
  but 
  I 
  believe 
  

   that 
  all 
  I 
  have 
  yet 
  had 
  an 
  opportunity 
  of 
  examining 
  are 
  Liassic 
  ; 
  and 
  I 
  do 
  not 
  

   think 
  that 
  beds 
  occurring 
  under 
  such 
  circumstances 
  offer 
  any 
  safe 
  indications 
  

   as 
  to 
  the 
  " 
  solid 
  " 
  geology 
  of 
  the 
  locality.
