ME.  S.  S.  BECKMAN  ON  THE  BAJOCIAN  [NoV.  1 893, 
hemera,  as  the  time  of  the  Moorei- beds  may  now  be  called  ; 1  but 
part  of  Bed  12  of  Stoford  may  belong  to  the  same  time.  The  strata 
of  the  discitce  and  bradforclensis  bemerse  were  not  recognized  at 
Stoford,  and  are  presumably  absent.2 
It  may  be  noted  that  the  celebrated  ‘  Marl  Bed  ’  of  Bradford 
Abbas,  which  forms  so  conspicuous  a  bench-mark  in  the  quarry,  is 
only  a  local  and  accidental  decomposition  of  the  top  of  Bed  5  ;  these 
two  beds,  4  and  5,  find  their  equivalents  in  8  and  9  of  Stoford. 
Bradford  Beds  2  and  3  may  also  be  correlated  with  Stoford  6  and  7 ; 
but  above  this  the  strata,  compared  with  Stoford,  have  increased  in 
thickness  at  Bradford,  where  the  top  of  the  section  is  incomplete. 
At  Bradford  Abbas,  by  the  Yicarage,  there  is  the  following  section 
in  the  ‘  top  beds.’

Denudation  has  left  only  a  thin  deposit  of  the  ‘  Fullers’  Earth 
Clay  ’  to  cap  this  section.  There  are  ]  0  feet  of  strata  shown  here, 
and  most  of  these  may  be  added  to  those  exposed  at  East  Hill. 
This  would  give  about  15-16  feet  of  ‘  top  beds  ’  as  against  2|  feet 
at  Stoford.  The  lower  part  of  the  ‘  top  beds  ’  at  East  Hill  belongs 
to  the  zigzag  hemera,  which  is  possibly  not  represented  at  Stoford. 
The  upper  part  at  East  Hill,  and  possibly  all  of  the  beds  at  the 
Yicarage,  belong  to  the  fuscoe  hemera,  during  which,  therefore,  there 
was  a  deeper  deposit  than  at  Stoford. 
A  little  more  than  1  mile  north-east  from  East  Hill  are  the 
well-known  exposures  of  Halfway  House,  giving  the  following 
sections : —

was  laid  down  during  the  bradfordensis  hemera.
