  Permian 
  breccia, 
  which 
  is 
  the 
  southerly 
  prolongation 
  of 
  the 
  outcrop 
  

   occurring 
  at 
  the 
  Boothorpe 
  Clay 
  Works, 
  described 
  in 
  detail 
  earlier 
  in 
  

   this 
  paper. 
  This 
  narrow 
  Permian 
  outcrop 
  can 
  be 
  traced 
  within 
  a 
  few 
  

   hundred 
  yards 
  of 
  the 
  Boothorpe 
  Grits, 
  but 
  the 
  dip 
  of 
  the 
  two 
  sets 
  of 
  

   beds 
  is 
  almost 
  diametrically 
  opposite, 
  that 
  of 
  the 
  grits 
  being 
  12° 
  to 
  

   lo° 
  N.W., 
  whilst 
  the 
  Permians 
  and 
  Trias 
  dip 
  6° 
  E.N.E. 
  More- 
  

   over 
  be 
  ween 
  the 
  western 
  edge 
  of 
  the 
  Triassic 
  outlier 
  and 
  the 
  

   Boothorpe 
  Grits 
  are 
  bluish 
  clays 
  of 
  the 
  ordinary 
  Coal-measure 
  

   type. 
  

  

  These 
  facts, 
  taken 
  together, 
  absolutely 
  negative 
  the 
  idea 
  of 
  the 
  

   Boothorpe 
  and 
  Moira 
  Grits 
  being 
  of 
  Permian 
  age 
  : 
  there 
  can 
  be 
  no 
  

   doubt 
  that 
  they 
  belong 
  to 
  the 
  Coal-measures, 
  but 
  I 
  have

  any 
  evidence 
  of 
  their 
  unconformity

  the

   beds. 
  It

  I 
  believe, 
  their 
  anomalous 
  red 
  colour 
  in 
  the 
  neigh- 
  

   bourhood 
  of 
  Boothorpe, 
  a 
  colour 
  unusual 
  in 
  Coal-measures, 
  which 
  

   has 
  led 
  some 
  observers 
  to 
  suspect 
  these

  to 
  be 
  of
