530  EAISED  BEACHES  A  HD  EOLLED  STONES  IN  JEESEY.  [Nov.  1893^ 
Also,  if  the  submergence  took  place,  as  seems  most  probable,  at 
the  end  of  the  post-Glacial  period,  the  peculiar  conditions  due  to 
melting  ice  and  previous  severe  climate  may  have  played  their  part 
in  the  formation  of  this  deposit.  In  describing  the  4  diluvial ’ 
deposits  of  la  Mancbe  (the  neighbouring  part  of  France),  Bon- 
nissent1  states  that  at  Eroudeville  some  blocks  of  a  granite  foreign 
to  the  neighbourhood  were  found  at  a  depth  of  about  15  metres 
(say  49  feet)  in  the  ‘  diluvium,’  the  largest  of  which  must  have 
weighed  about  120  kilogrammes  (say  264  lbs.). 
Mr.  Danby,  on  the  authority  of  Dr.  M.  Bull,  says  that  the  raised 
beach  on  the  west  of  the  island  of  Jersey  contained  quantities  of 
recent  shells.  In  none  of  the  beaches  which  I  have  examined, 
however,  have  I  as  yet  found  any  fossils.  A  bone  of  Bos  primi- 
genius  (?)  was  found  in  the  brick-clay  near  Pontac  while  the  Eastern 
Railway  was  being  laid  down. 
Discussion. 
The  Peesident  had  no  doubt  that  the  paper  would  be  of  interest  to 
students  of  Pleistocene  geology.  It  was  curious  that  the  maximum 
submergence  (130  feet)  referred  to  by  the  Author  coincided  exactly 
with  the  height  of  the  raised  beaches  at  Goodwood. 
The  Rev.  H.  H.  Winwood  said  he  was  familiar  with  raised  beaches 
in  the  South-west  of  England,  and  he  asked  what  evidence  had  been 
brought  forward  that  this  was  a  raised  beach  at  all.  The  presence 
of  rolled  stones  alone,  without  any  trace  of  fossil  shells,  was  hardly 
sufficient  to  establish  the  writer’s  theory. 
Mr.  Monceton  also  spoke.
