Bed  1  was  not  found  at  Sandford  Lane,  but  can  be  correlated 
with  Bed  4  at  Louse  Hill.  The  flat  top  of  Bed  2  suggests  corre¬ 
lation  with  the  flat  top  of  the  4  Fossil  Bed  ’  at  Sandford  Lane,  but 
this  is  a  mistake.  The  true  explanation  is  that  here,  as  well  as  at 
Sandford  Lane,  a  hiatus  exists  ;  but  that  the  erosion,  to  which  the 
flat  top  probably  points,  removed  more  strata  at  Sandford  Lane  than 
here.  In  fact,  probably  a  part  of  the  next  bed  is  unrepresented  at 
the  former  locality. 
The  agreement  of  Bed  4  with  an  horizon  a  few  inches  from  the  top 
of  the  Sandford  Lane  4  Fossil  Bed  ’  is  absolutely  exact ;  and  the 
lower  part  of  that  bed  is  represented  by  Beds  5  and  6.  Ammonites, 
however,  are  scarcer  here;  and  many  large  (unnamed)  species,  so 
characteristic  of  Sandford  Lane,  are  conspicuous  by  their  absence. 
In  the  next  20  inches  of  strata  we  are  on  an  horizon  evidently 
lower  than  that  of  the  4 Fossil  Bed’  of  Sandford  Lane,  and  Bed  10 
can  be  correlated  with  Beds  9  or  10  at  Sandford  Lane.  The  strata 
of  the  true  concavi  hemera  were  not  reached,  and  without  a  larger 
excavation  it  was  difficult  to  go  deeper  down.  It  was  considered 
ihat  the  evidence  as  to  having  reached  an  horizon  decidedly  below 
the  4  Fossil  Bed  ’  of  Sandford  Lane  was  sufficient. 
The  identity  or  otherwise  of  the  Sandford  Lane  4  Fossil  Bed  ?  and 
the  green-grained  marl  of  Frogden  Quarry,  Oborne,  still  remained 
to  be  settled.  I  therefore  made  a  fresh  section  at  Oborne,  but,  as 
the  quarry  was  not  being  worked,  the  exact  position  of  a  large
