﻿PROCEEDINGS 
  OF 
  THE 
  GEOLOGICAL 
  SOCIETY. 
  

  

  The 
  Eruptive 
  ^Rocks 
  should 
  be 
  marked 
  with 
  the 
  Greek 
  capital 
  

   letter 
  of 
  the 
  name. 
  

  

  The 
  Congress 
  resolved 
  to 
  prepare 
  and 
  publish 
  a 
  geological 
  map 
  of 
  

   Europe, 
  correlating, 
  as 
  far 
  as 
  possible, 
  the 
  work 
  of 
  the 
  various 
  

   national 
  surveys 
  and 
  that 
  of 
  independent 
  observers. 
  The 
  dis- 
  

   cussion 
  of 
  the 
  details 
  of 
  this 
  question 
  was 
  referred 
  to 
  a 
  Commission, 
  

   consisting 
  of 
  the 
  President, 
  Vice-Presidents, 
  and 
  a 
  few 
  other 
  

   members 
  of 
  the 
  Congress. 
  

  

  Of 
  this 
  Commission 
  Prof. 
  Daubree 
  was 
  President 
  and 
  Prof. 
  

   Dewalque 
  Secretary 
  ; 
  the 
  latter 
  has 
  printed 
  a 
  report 
  of 
  its 
  pro- 
  

   ceedings 
  (Liege, 
  1881, 
  pp. 
  16). 
  

  

  The 
  Commission 
  recommended 
  that 
  the 
  map 
  should 
  be 
  published 
  

   at 
  Berlin, 
  on 
  the 
  scale 
  of 
  1 
  : 
  1,500,000 
  (about 
  25 
  miles 
  to 
  one 
  inch). 
  

   This 
  map 
  will 
  require 
  50 
  sheets, 
  and 
  will 
  be 
  so 
  arranged 
  that 
  any 
  

   number 
  of 
  the 
  sheets 
  can 
  be 
  mounted 
  together 
  to 
  show 
  any 
  required 
  

   area. 
  The 
  complete 
  map 
  will 
  be 
  about 
  12 
  feet 
  by 
  10 
  feet. 
  Much 
  

   discussion 
  took 
  place 
  as 
  to 
  the 
  constitution 
  of 
  the 
  Committee 
  which 
  

   should 
  be 
  intrusted 
  with 
  the 
  work. 
  The 
  Commission 
  finally 
  recom- 
  

   mended 
  that 
  representatives 
  of 
  five 
  countries 
  would 
  suffice. 
  In 
  

   voting 
  upon 
  which 
  those 
  countries 
  should 
  be, 
  Great 
  Britain 
  received 
  

   the 
  votes 
  of 
  all, 
  France 
  coming 
  next, 
  Germany 
  third, 
  Russia 
  fourth. 
  

   A 
  second 
  ballot 
  being 
  taken 
  for 
  the 
  fifth 
  country, 
  Austro-Hungary 
  

   was 
  chosen. 
  

  

  The 
  cost 
  of 
  preparing 
  the 
  map 
  at 
  Berlin 
  is 
  estimated 
  at 
  about 
  

   £2500. 
  The 
  various 
  governments 
  of 
  Europe 
  will 
  be 
  asked 
  to 
  con- 
  

   tribute 
  to 
  this 
  — 
  the 
  eight 
  larger 
  countries 
  in 
  equal 
  proportions, 
  

   about 
  £280 
  each, 
  the 
  ninth 
  part 
  being 
  divided 
  amongst 
  some 
  of 
  the 
  

   smaller 
  States. 
  

  

  These 
  recommendations 
  were 
  adopted 
  by 
  the 
  Congress, 
  with 
  some 
  

   modification 
  as 
  regards 
  the 
  number 
  of 
  the 
  Committee, 
  which 
  now 
  

   stands 
  thus 
  : 
  — 
  

  

  Austro-Hungary 
  Dr. 
  E. 
  von 
  Mojsisovics. 
  

  

  France 
  Prof. 
  Daubree. 
  

  

  p 
  J 
  Dr. 
  E. 
  Beyrich 
  (Director) 
  and 
  W. 
  

  

  Germany 
  ^ 
  Hauchecorne 
  (Assistant 
  Director). 
  

  

  Great 
  Britain 
  W. 
  Topley. 
  

  

  Italy 
  F. 
  Giordano. 
  

  

  Russia 
  Prof, 
  von 
  Moller. 
  

  

  Switzerland 
  Prof. 
  Renevier 
  (Secretary). 
  

  

  Each 
  member 
  of 
  the 
  Committee 
  is 
  to 
  supply 
  a 
  map 
  of 
  the 
  country 
  

   allotted 
  to 
  him 
  on 
  the 
  required 
  scale, 
  and 
  ready 
  for 
  engraving 
  at 
  

   Berlin, 
  where 
  the 
  topographical 
  map 
  is 
  already 
  in 
  preparation. 
  

  

  In 
  the 
  cases 
  of 
  countries 
  not 
  directly 
  represented 
  on 
  the 
  Com- 
  

   mittee, 
  arrangements 
  will 
  subsequently 
  be 
  made 
  for 
  obtaining 
  the 
  

   required 
  information. 
  But 
  some 
  such 
  arrangements 
  were 
  then 
  

   agreed 
  to, 
  and 
  Austria 
  will 
  supply 
  the 
  geology 
  of 
  Turkey. 
  Parts 
  of 
  

   Africa 
  and 
  Asia 
  come 
  within 
  the 
  map. 
  Of 
  these, 
  France 
  will 
  supply
