﻿666 
  PROF. 
  C. 
  LAPWORTH 
  ON 
  THE 
  GIRVAN 
  SUCCESSION. 
  

  

  the 
  Lower 
  May- 
  Hill. 
  On 
  either 
  side 
  of 
  the 
  Lake-district 
  (at 
  Rebecca 
  

   Hill, 
  Ireleth, 
  and 
  at 
  the 
  west 
  end 
  of 
  the 
  Craven 
  district) 
  a 
  conglo- 
  

   meratic 
  base 
  marks 
  the 
  horizon 
  of 
  a 
  break 
  corresponding 
  to 
  that 
  

   described 
  by 
  Prof. 
  Lapworth 
  at 
  the 
  base 
  of 
  his 
  Upper 
  series. 
  

  

  Mr. 
  Etheridge 
  expressed 
  his 
  high 
  opinion 
  of 
  the 
  work 
  done 
  by 
  

   Prof. 
  Lapworth. 
  It 
  was 
  most 
  satisfactory 
  to 
  thus 
  see 
  how 
  important 
  

   palaeontological 
  evidence 
  became 
  in 
  unravelling 
  a 
  difficult 
  country. 
  

   The 
  mistake 
  of 
  not 
  paying 
  sufficient 
  attention 
  to 
  palaeontology 
  had, 
  

   he 
  thought, 
  been 
  made 
  in 
  mapping 
  the 
  northern 
  part 
  of 
  Britain. 
  

   He 
  believed 
  that 
  Prof. 
  Lapworth 
  had 
  successfully 
  unravelled 
  this 
  

   difficult 
  region 
  ; 
  and 
  we 
  should 
  be 
  thankful 
  to 
  him 
  for 
  the 
  un- 
  

   wearied 
  labour 
  and 
  the 
  patience 
  and 
  knowledge 
  he 
  had 
  brought 
  to 
  

   bear 
  upon 
  it. 
  

  

  Prof. 
  Lapworth, 
  in 
  reply, 
  thanked 
  the 
  Meeting 
  for 
  the 
  reception 
  

   it 
  had 
  given 
  him. 
  In 
  the 
  present 
  part 
  of 
  his 
  paper 
  he 
  had 
  dwelt 
  

   mainly 
  on 
  stratigraphical 
  arguments; 
  but, 
  as 
  regards 
  the 
  second 
  

   part, 
  he 
  must 
  express 
  his 
  gratitude 
  to 
  Dr. 
  Davidson 
  for 
  what 
  he 
  

   had 
  done 
  in 
  aiding 
  him. 
  He 
  had 
  also 
  said 
  little 
  about 
  Mrs. 
  Gray's 
  

   collection, 
  as 
  that 
  was 
  in 
  process 
  of 
  being 
  described, 
  and 
  would 
  be 
  

   treated 
  in 
  detail 
  in 
  the 
  succeeding 
  portion 
  of 
  the 
  memoir. 
  As 
  re- 
  

   gards 
  the 
  older 
  rocks 
  mentioned 
  by 
  Dr. 
  Hicks 
  he 
  said 
  little, 
  as 
  it 
  

   was 
  foreign 
  to 
  his 
  paper 
  ; 
  but 
  the 
  Ballantrae 
  rocks 
  were 
  certainly 
  

   older 
  than 
  the 
  Girvan 
  beds, 
  as 
  fragments 
  of 
  them 
  occurred 
  in 
  con- 
  

   glomerates 
  at 
  the 
  base 
  of 
  the 
  Girvan 
  rocks, 
  and 
  the 
  latter 
  overlie 
  

   them. 
  With 
  regard 
  to 
  the 
  basement 
  beds 
  of 
  the 
  Llandovery 
  

   in 
  North 
  Wales, 
  he 
  had 
  examined 
  them 
  and 
  believed 
  there 
  were 
  

   three 
  series, 
  as 
  in 
  Scotland, 
  — 
  one 
  only 
  near 
  Birmingham, 
  two 
  as 
  

   you 
  approached 
  the 
  Stiper 
  Stones, 
  and 
  a 
  third 
  in 
  the 
  Welshpool 
  

   area 
  ; 
  so 
  that 
  he 
  was 
  in 
  favour 
  of 
  putting 
  all 
  the 
  Llandovery 
  beds 
  

   into 
  the 
  Silurian. 
  He 
  thanked 
  Mr. 
  Etheridge 
  for 
  his 
  support, 
  and 
  

   would 
  call 
  attention 
  to 
  the 
  valuable 
  work 
  done 
  by 
  Mr. 
  Etheridge, 
  

   Jun., 
  on 
  the 
  fossils 
  from 
  this 
  locality. 
  He 
  called 
  attention 
  to 
  the 
  

   way 
  in 
  which 
  his 
  own 
  work 
  bore 
  out 
  Dr. 
  Smith's 
  dictum 
  of 
  " 
  strata 
  

   identified 
  by 
  superposition 
  and 
  organic 
  remains."
