  In 
  the 
  year 
  1888, 
  during 
  a 
  visit 
  to 
  Sir 
  J. 
  Prestwich, 
  I 
  had 
  the 
  

   opportunity 
  of 
  examining 
  his 
  Pleistocene 
  collection. 
  I 
  saw 
  among 
  

   the 
  specimens 
  two 
  lumps 
  of 
  clay 
  which 
  had 
  been 
  collected 
  at 
  Case- 
  

   wick 
  and 
  at 
  Shacklewell, 
  to 
  illustrate 
  papers 
  by 
  Morris 
  and 
  by 
  

   himself. 
  These 
  he 
  kindly 
  permitted 
  me 
  to 
  take 
  away 
  and 
  examine, 
  

   and 
  out 
  of 
  them 
  I 
  obtained 
  the 
  plants 
  mentioned 
  below. 
  In 
  

   Prestwich's 
  collection 
  I 
  observed 
  also 
  a 
  number 
  of 
  plant-remains 
  

   from 
  Grays, 
  which 
  had 
  been 
  partially 
  determined 
  in 
  1861 
  byGaudin 
  

   and 
  Heer. 
  These, 
  however, 
  I 
  was 
  unable 
  at 
  the 
  time 
  to 
  study, 
  for 
  

   Prestwich 
  informed 
  me 
  that 
  he 
  was 
  then 
  engaged 
  on 
  a 
  paper 
  in 
  

   which 
  the 
  deposits 
  at 
  Grays 
  would 
  be 
  described. 
  He 
  died 
  without 
  

   completing 
  the 
  work, 
  and 
  his 
  collection 
  was 
  given 
  to 
  the 
  Natural 
  

   History 
  Museum, 
  Lady 
  Prestwich 
  informing 
  Dr. 
  Woodward 
  and 
  

   myself 
  that 
  it 
  was 
  Sir 
  Joseph's 
  request 
  that 
  I 
  should 
  complete 
  the 
  

   examination 
  of 
  his 
  Pleistocene 
  plants. 
  In 
  this 
  manner 
  it 
  happens 
  

   that 
  I 
  am 
  now 
  writing 
  a 
  botanical 
  supplement 
  to 
  papers 
  which 
  

   were 
  read 
  before 
  the 
  Society 
  at 
  such 
  distant 
  dates 
  as 
  1853, 
  1855, 
  

   and 
  1869. 
  

  

  Casewick 
  (Lincolnshire.) 
  

  

  The 
  alluvial 
  deposit 
  at 
  this 
  locality 
  was 
  described 
  by 
  the 
  late 
  

   Prof. 
  John 
  Morris, 
  who 
  gave 
  to 
  Prestwich 
  the 
  lump 
  of 
  clay 
  from 
  

   which 
  I 
  obtained 
  the 
  plants. 
  There 
  is 
  nothing 
  in 
  the 
  list 
  to 
  throw 
  

   any 
  light 
  on 
  the 
  age 
  of 
  the 
  deposit, 
  and 
  so 
  far 
  as 
  the 
  flora 
  shows 
  

   it 
  may 
  be 
  of 
  extremely 
  recent 
  date 
  : 
  — 
  

  

  Nuphar 
  lutevm, 
  L. 
  

   Galium 
  Aparine, 
  L. 
  

   Atriplex 
  patala, 
  L. 
  

   Bumex 
  crispus, 
  L. 
  

   Ceratophi/llum 
  demersum, 
  L. 
  

   Scirpus 
  lacustri", 
  L. 
  

  

  ^ 
  Shacklewell 
  (Middlesex). 
  

  

  The 
  peaty 
  clay 
  was 
  obtained 
  by 
  Prestwich 
  from 
  beneath 
  8 
  or 
  

   10 
  feet 
  of 
  gravel 
  ; 
  but 
  neither 
  the 
  mollusca 
  nor 
  the 
  plants 
  point 
  to
