  [Plate

  In 
  this 
  paper 
  I 
  have 
  not 
  made 
  any 
  attempt 
  to 
  correlate 
  the 
  Gault 
  

   of 
  Folkestone 
  with 
  beds 
  of 
  similar 
  age 
  in 
  other 
  parts 
  of 
  England 
  or 
  

   of 
  the 
  Continent, 
  but 
  simply 
  to 
  describe 
  the 
  Gault 
  as 
  seen 
  at 
  Folke- 
  

   stone, 
  and 
  to 
  give 
  a 
  list 
  of 
  its 
  fossils. 
  

  

  Not 
  having 
  had 
  time 
  to 
  examine 
  the 
  Gault 
  in 
  other 
  parts 
  of 
  Eng- 
  

   land, 
  I 
  am 
  not 
  in 
  a 
  position 
  at 
  present 
  to 
  state 
  whether 
  these 
  divi- 
  

   sions 
  will 
  hold 
  good 
  over 
  extended 
  areas. 
  

  

  Upon 
  some 
  future 
  occasion 
  I 
  hope 
  to 
  place 
  before 
  this 
  Society 
  a 
  more 
  

   general 
  paper 
  upon 
  the 
  Gault, 
  correlating 
  the 
  various 
  beds. 
  

  

  The 
  Geological 
  Magazine 
  for 
  April, 
  1868 
  (voJ. 
  v. 
  No. 
  4), 
  contains 
  

   a 
  most 
  valuable 
  paper 
  entitled 
  the 
  '' 
  Albian 
  or 
  Gault 
  of 
  Folkestone," 
  

   by 
  Mr. 
  Charles 
  E. 
  De 
  Ranee, 
  of 
  the 
  Geological 
  Survey. 
  In 
  tbis 
  paper 
  

   Mr. 
  De 
  Ranee 
  divides 
  the 
  Gault 
  into 
  eleven 
  zones, 
  all 
  of 
  which 
  are 
  

   well 
  marked 
  and 
  have 
  been 
  recognized 
  more 
  or 
  less 
  by 
  all 
  geologists 
  

   and 
  fossil- 
  collectors 
  who 
  have 
  visited 
  the 
  district. 
  

  

  Provisional 
  names 
  have 
  been 
  assigned 
  to 
  these 
  beds, 
  indicative 
  

   either 
  of 
  their 
  colour, 
  position, 
  or 
  fossil 
  contents. 
  

  

  Having 
  investigated 
  the 
  whole 
  of 
  the 
  Gault 
  at 
  Copt 
  Point 
  and 
  in 
  

   Eastweir 
  Bay, 
  which 
  lies 
  about 
  one 
  mile 
  to 
  the 
  eastward 
  of 
  Folkestone 
  

   harbour, 
  where 
  it 
  may 
  be 
  seen 
  resting 
  upon 
  the 
  Folkestone-beds 
  of 
  

   the 
  Lower 
  Greensand 
  or 
  Upper 
  Neocomian, 
  and 
  found 
  that, 
  for 
  the 
  

   most 
  part, 
  Mr. 
  De 
  Ranee's 
  division 
  into 
  zones 
  or 
  beds 
  holds 
  good, 
  I 
  

   consider 
  that 
  we 
  cannot 
  do 
  better 
  than 
  adopt 
  his 
  order 
  of 
  dividing 
  

   the 
  Gaidt 
  into 
  the 
  various 
  beds 
  which 
  I 
  propose 
  describing 
  in 
  this 
  

   paper, 
  setting 
  forth 
  one 
  or 
  two 
  points 
  on 
  which 
  I 
  disagree. 
  

  

  It 
  is 
  exceedingly 
  difficult 
  for 
  any 
  one 
  who 
  has 
  not 
  thoroughly 
  in- 
  

   vestigated 
  the 
  Gault 
  in 
  situ 
  to 
  be 
  able 
  to 
  discern 
  the 
  various 
  beds 
  as 
  

   they 
  lie 
  on 
  the 
  beach 
  in 
  Eastweir 
  Bay. 
  In 
  consequence 
  of 
  the 
  slipping 
  

   of 
  the 
  Chalk 
  above, 
  the 
  Gault 
  has 
  been 
  pressed 
  out 
  and 
  faulted 
  in 
  great 
  

   confusion, 
  many 
  of 
  the 
  bods 
  being 
  mixed 
  up 
  together. 
  

  

  The 
  lithological 
  characteristics 
  once 
  familiar 
  to 
  the 
  investigator, 
  he 
  

   will 
  plainly 
  see 
  how 
  utterly 
  impossible 
  it 
  would 
  be 
  for 
  any 
  one 
  to 
  

   attempt 
  taking 
  accurate 
  measurements 
  of 
  the 
  beds 
  as 
  they 
  are 
  there 
  

   placed. 
  They 
  are 
  not 
  merely 
  mixed, 
  but 
  are 
  much 
  expanded 
  in 
  

   comparison 
  with 
  what 
  they 
  are 
  at 
  Copt 
  Point, 
  where 
  the 
  only 
  accurate 
  

   measurements 
  can 
  be 
  obtained, 
  the 
  Gault 
  at 
  that 
  place 
  being 
  in 
  situ, 
  

   and 
  capped 
  by 
  the 
  Upper 
  Greensand. 
  

  

  The 
  Gault 
  of 
  Eastweir 
  Bay 
  is 
  always 
  moving, 
  and 
  in 
  very 
  wet 
  

   weather 
  may 
  almost 
  be 
  seen 
  to 
  move, 
  as 
  the 
  quantity 
  of 
  water 
  per- 
  

   colating 
  through 
  the 
  Chalk 
  to 
  the 
  Gault, 
  where 
  it 
  meets 
  with 
  an 
  ob- 
  

   stacle, 
  causes 
  the 
  Chalk 
  above 
  to 
  press 
  out 
  these 
  lower 
  beds. 
  I 
  do 
  

   not 
  think 
  the 
  day 
  is 
  very 
  remote 
  when 
  we 
  shall 
  have 
  to 
  record 
  a 
  con-
