PROCEEDINGS  OF  THE  GEOLOGICAL  SOCIETY.  [May  1893, 
Isles,  besides  one  or  two  referring  to  foreign  localities.  With  these 
may  be  grouped  about  half  a  dozen  papers  which  deal  with  theo¬ 
retical  questions  in  connexion  with  glaciation.  It  is  scarcely 
necessary  to  remind  you  that  the  Nestor  of  British  Geology, 
Prof.  Prestwich,  has  been  one  of  the  chief  contributors  to  this  branch 
of  our  science.  As  the  subject  is  a  popular  one,  I  have  dwelt  upon  it 
at  some  length,  always  with  the  express  reservation  that  I  have  no 
special  qualifications  for  the  task. 
In  Tertiary  Geology  there  was  an  important  paper  by  Messrs. 
P.  P.  Kendall  and  B.  G.  Bell  on  the  Pliocene  Beds  of  St.  Erth,  and 
about  a  dozen  papers  on  various  members  of  the  Eocene,  especially 
on  the  Bagshots  of  the  western  part  of  the  London  Basin  ;  Dr.  Irving 
and  Messrs.  Monckton  and  Herries  distinguished  themselves  in  this 
connexion.  Prof.  Prestwich  contributed  an  important  paper  on  the 
correlation  of  the  Eocene  strata  in  England,  Belgium,  and  the 
North  of  Erance,  and  Mr.  Starkie  Gardner,  with  the  assistance  of 
Messrs.  Keeping  and  Monckton,  contributed  a  very  useful  paper 
on  the  Upper  Eocene,  comprising  the  Barton  and  Upper  Bagshot 
formations. 
Under  the  heading  of  Tertiary  Geology  it  will  be  convenient  also 
to  consider  certain  oceanic  deposits  in  the  West  Indies  and  else¬ 
where,  with  more  particular  reference  to  the  island  of  Barbados. 
The  papers  on  Cretaceous  Geology,  including  some  specially  de¬ 
voted  to  palaeontological  subjects,  are  about  nine  in  number,  and 
among  these  are  memoirs  by  Messrs,  Jukes-Browne,  William  Hill, 
and  Lamplugh,  which  will  require  to  be  considered  in  some  detail. 
There  have  been  about  fifteen  papers  on  Jurassic  Geology, 
including  the  Rhcetic.  Most  of  these  relate  to  English  localities,  and 
a  few  are  purely  palaeontological.  The  correlation  of  the  Upper 
Jurassic  strata  of  the  Swiss  Jura  with  those  of  England  was  a 
valuable  contribution  from  the  late  Thomas  Iioberts,  of  the  Wood- 
wardian  Museum.  There  is  also  an  important  paper  by  Mr.  S.  S. 
Buckman  on  the  Cotteswold,  Midford,  and  Yeovil  Sands,  and  con¬ 
tributions  from  other  well-known  authors,  to  some  of  which  I  hope 
to  be  able  to  draw  your  attention  with  more  detail  subsequently. 
It  might  have  been  surmised  that  there  was  not  much  left  to 
say  on  the  Triassic  and  Permian  formations.  Yet  we  have  had 
eight  papers,  including  one  by  Mr.  Wilson  on  the  Durham  Salt 
district,  and  a  very  interesting  paper  by  Mr.  Horace  T.  Brown  on 
the  Permian  rocks  of  the  Leicestershire  Coal-field  ;  while  Messrs. 
Irving  and  Hull  have  given  us  their  views  on  the  Bed  Bocks  of
