  In 
  the 
  latter 
  case 
  the 
  hored 
  surface 
  is 
  underneath, 
  for 
  there 
  was 
  

   an 
  Aalenian 
  denudation 
  of 
  the 
  Upper 
  Freestone; 
  and 
  the 
  lower 
  

   stratum 
  is 
  found 
  to 
  fail 
  while 
  the 
  upper 
  one 
  continues. 
  Hence 
  an 
  

   upper 
  bed 
  overlaps 
  a 
  lower 
  one, 
  as 
  the 
  Harford 
  Sands 
  are 
  

   found 
  at 
  Cleeve, 
  with 
  the 
  other 
  deposits, 
  but 
  only 
  a 
  thin 
  bed 
  of 
  

   Snowshill 
  Clay 
  is 
  found 
  at 
  Leckhampton 
  ; 
  while 
  neither 
  are 
  present 
  

   to 
  the 
  south. 
  So 
  the 
  case 
  stands 
  thus

  This 
  difference, 
  in 
  connexion 
  with 
  any 
  absence 
  of 
  deposits, 
  requires 
  

   to 
  be 
  carefully 
  noted.

  It 
  is 
  generally 
  taught 
  that 
  between 
  the 
  Fullers' 
  Earth 
  above 
  and 
  

   the 
  Upper 
  Lias 
  below 
  there 
  is 
  no 
  impervious 
  or 
  water-retaining 
  

   deposit. 
  Exception 
  must 
  be 
  taken 
  to 
  this 
  statement 
  in 
  several 
  cases 
  ; 
  

   but 
  it 
  is 
  particularly 
  incorrect 
  with 
  regard 
  to 
  the 
  Northern 
  Cottes- 
  

   wolds. 
  The 
  Snowshill 
  Clay 
  is 
  an 
  impervious 
  bed 
  ; 
  and 
  its 
  position 
  

   lies 
  about 
  the 
  middle 
  of 
  what 
  is 
  indefinitely 
  called 
  ' 
  Inferior 
  

   Oolite.' 
  In 
  a 
  district 
  where 
  water 
  is 
  obtainable 
  only

  difficulty
