  The 
  true 
  position 
  of 
  the 
  Stone-beds 
  is 
  probably 
  that 
  

   horizon 
  of 
  the 
  Opalinum-zo\\Q 
  which 
  I 
  have 
  designated 
  Moorei-heds. 
  

   In 
  this 
  connexion 
  it 
  is 
  interesting 
  to 
  notice 
  that 
  a 
  Dumort'teria, 
  

   probably 
  referable 
  to 
  Dam. 
  rliodanica, 
  was 
  met 
  with 
  in 
  the 
  Yellow 
  

   Sands 
  below, 
  and 
  also 
  that 
  the 
  shell-bed 
  at 
  Stoford 
  contains 
  exactly 
  

   the 
  same 
  Ammonites 
  as 
  the 
  Moorei-heds 
  of 
  Buckholt 
  Wood 
  and 
  other 
  

   Cotteswold 
  localities.

  layers 
  of

  The 
  

   stone 
  is 
  full 
  of 
  comminuted 
  shells. 
  It 
  is 
  

   generally 
  buried 
  in

  These 
  Yellow 
  Sands 
  were 
  observed 
  in 
  the 
  lane 
  leading 
  from 
  Mon- 
  

   tacute 
  to 
  the 
  top 
  of 
  the 
  Hill. 
  They 
  seem 
  to 
  begin 
  just 
  above 
  Mon- 
  

   tacute 
  Church 
  and 
  to 
  continue 
  the 
  whole 
  distance. 
  A 
  few 
  yards 
  

   then 
  brings 
  one 
  to 
  the 
  freestone-quarry 
  measured, 
  which, 
  it 
  will 
  be 
  

   seen, 
  extends 
  90 
  feet 
  in 
  depth. 
  It 
  would 
  therefore 
  seem 
  as 
  if 
  the 
  

   freestone 
  had 
  been 
  let 
  in 
  by 
  a 
  fault, 
  something 
  like 
  85 
  feet. 
  The 
  

   " 
  Bottom 
  Bed 
  " 
  crops 
  out 
  in 
  the 
  lane 
  near 
  some 
  fir 
  trees 
  ; 
  while 
  on 
  

   the 
  opposite 
  side 
  of 
  the 
  road 
  there 
  is 
  a 
  quarry 
  of 
  rough 
  stone 
  

   evidently 
  faulted 
  down. 
  

  

  I 
  beg 
  to 
  express 
  my 
  thanks 
  to 
  the 
  Director-General 
  of 
  the 
  Ord- 
  

   nance 
  Survey, 
  who 
  very 
  kindly 
  gave 
  me 
  the 
  height 
  of 
  Ham 
  Hill. 
  It 
  

   is 
  about 
  90 
  feet 
  above 
  Montacute 
  church. 
  

  

  The 
  next 
  section 
  is 
  important, 
  because 
  it 
  exhibits 
  the 
  junction 
  

   of 
  the 
  Yeovil 
  Sands 
  with 
  Upper-Lias 
  Clay. 
  It 
  is 
  noticeable 
  that 
  

   now 
  the 
  yellow 
  micaceous 
  sands 
  do 
  not 
  begin 
  until 
  we 
  have 
  

   finished 
  with 
  the 
  Dispansum-be&s 
  ; 
  while 
  the 
  Upper-Lias 
  Clay 
  is 
  

   here 
  exactly 
  contemporaneous 
  with 
  the 
  Cotteswold 
  Sands, 
  together 
  

   with 
  the 
  two 
  lower 
  divisions 
  of 
  the 
  Cotteswold 
  Cephalopoda-bed.
