  In 
  

   July 
  of 
  the 
  same 
  year 
  Mr. 
  Hamling 
  was 
  good 
  enough, 
  at 
  my 
  

   request, 
  to 
  visit 
  the 
  Oakhampton 
  slate-quarry 
  near 
  Wiveliscombe, 
  

   and 
  afterwards 
  to 
  send 
  me 
  some 
  specimens. 
  In 
  the 
  following 
  August 
  

   Mr. 
  Hamling, 
  Mr. 
  Whidborne, 
  and 
  I 
  collected 
  other 
  specimens 
  from 
  

   this 
  quarry, 
  and 
  afterwards 
  we 
  also 
  obtained 
  some 
  fossils 
  from 
  the 
  

   Combe 
  quarries 
  near 
  Whitfield, 
  on 
  the 
  opposite 
  side 
  of 
  the

  Both 
  the 
  Oakhampton 
  and 
  the 
  Treborough 
  quarries 
  have 
  

   been 
  since 
  visited 
  by 
  us 
  on 
  many 
  occasions, 
  and 
  numerous 
  fossils 
  

   have 
  been 
  collected 
  from 
  each. 
  We 
  have 
  also 
  made 
  several 
  traverses 
  

   across 
  the 
  district 
  intervening 
  between 
  Treborough 
  and 
  Oakhampton, 
  

   and 
  have 
  explored 
  the 
  rocks 
  to 
  the 
  north 
  and 
  south, 
  and 
  collected 
  

   largely 
  from 
  those 
  beds.

  The 
  so-called 
  Morte 
  Slates 
  vary 
  considerably 
  in 
  character 
  in 
  dif- 
  

   ferent 
  areas, 
  and 
  probably 
  include 
  beds 
  of 
  very 
  different 
  age. 
  Some 
  

   of 
  these 
  may 
  be 
  faulted 
  patches 
  thrust 
  in 
  among 
  the 
  older 
  rocks 
  ; 
  

   but 
  as 
  there 
  is 
  no 
  pakeontological 
  evidence 
  to 
  guide 
  us 
  as 
  to 
  their 
  

   age, 
  they 
  cannot, 
  at 
  present, 
  be 
  properly 
  classified. 
  Paults 
  are 
  of 
  

   frequent 
  occurrence, 
  and 
  the 
  beds 
  in 
  places 
  are 
  much 
  crushed, 
  though 
  

   not 
  so 
  much 
  as 
  in 
  North 
  Devon.
