Note. — The  thickness,  colour,  and  hardness  of  the  beds  are  verj' 
variable.  Planes  of  division  uneven — the  lower  beds  being 
f  pocketty/  Bed  10  thickens  to  about  1  foot  at  the  south  of  the 
quarry. 
Bed  10  is  the  most  interesting  for  the  present.  Several  specimens 
of  4  Stephanoceras  ’  Sauzei  have  come  from  here  at  different  times — 
the  matrix  is  unmistakable.  The  4  incompleteness  of  the  record  5 
and  the  attenuation  of  the  deposits  are  especially  noticeable. 
About  1|  mile  in  a  north-easterly  direction  lies  the  famous  East 
Hill  Quarry  of  Bradford  Abbas.  The  section  of  this  has  been  often 
given ;  but,  considering  how  remarkably  rich  is  the  fauna  here 
stowed  away  in  a  small  compass,  the  section  has  never  been 
described  with  sufficient  detail.  In  fact  the  necessity  for  the  detail 
has  not  been  taught,  and  was  not  appreciated.  The  present  section 
is  far  from  satisfying  my  requirements  in  regard  to  specific  horizons, 
but  the  quarry  was  not  4  in  work/*
