  The 
  south 
  coast 
  of 
  Devonshire 
  from 
  Petit 
  Tor, 
  near 
  Babbacombe 
  

   Bay, 
  to 
  a 
  little 
  beyond 
  Sidmouth, 
  exhibits 
  cliffs 
  of 
  New 
  Red 
  Sand- 
  

   stone, 
  one 
  of 
  the 
  beds 
  of 
  which, 
  near 
  Budleigh 
  Salterton, 
  is 
  com- 
  

   posed 
  of 
  pebbles 
  of 
  all 
  sizes 
  and 
  of 
  a 
  flattened 
  oval 
  form 
  ; 
  this 
  bed 
  

   attains 
  a 
  maximum 
  thickness 
  of 
  about 
  100 
  feet, 
  and 
  some 
  of 
  the 
  

   pebbles 
  composing 
  it 
  were 
  found 
  by 
  Mr. 
  Yicary 
  to 
  contain 
  peculiar 
  

   fossils. 
  

  

  Mr. 
  Yicary 
  gave 
  a 
  description 
  of 
  the 
  physical 
  features 
  of 
  the 
  area 
  

   over 
  which 
  the 
  pebble-bed 
  extends, 
  and 
  entered 
  into 
  the 
  stratigra- 
  

   phical 
  details 
  of 
  this 
  and 
  the 
  associated 
  strata, 
  referring 
  to 
  Mr. 
  

   Salter's 
  Note 
  for 
  information 
  upon 
  the 
  affinities 
  of 
  the 
  fossils. 
  

  

  In 
  his 
  Note, 
  Mr. 
  Salter 
  observed 
  that, 
  on 
  comparing 
  the 
  fossils 
  of 
  

   the 
  Budleigh- 
  Salterton 
  pebbles 
  with 
  those 
  from 
  the 
  Caen 
  sandstone 
  

   in 
  the 
  Society's 
  Museum, 
  he 
  found 
  that 
  all 
  the 
  species 
  contained 
  in 
  

   the 
  latter 
  collection 
  were 
  also 
  represented 
  in 
  the 
  former. 
  The 
  

   general 
  aspect 
  of 
  the 
  fossils 
  was 
  stated 
  to 
  be 
  quite 
  unlike 
  that 
  ex- 
  

   hibited 
  by 
  English 
  Lower 
  Silurian 
  collections 
  ; 
  and 
  Mr. 
  Salter 
  there- 
  

   fore 
  suggested 
  that 
  the 
  exact 
  equivalent 
  of 
  the 
  Caen 
  sandstone 
  does 
  

   not 
  exist 
  in 
  England. 
  This 
  difference 
  in 
  the 
  two 
  faunas 
  appeared 
  

   to 
  him 
  to 
  favour 
  the 
  theory 
  of 
  the 
  former 
  existence 
  of 
  a 
  barrier 
  be- 
  

   tween 
  the 
  middle 
  and 
  northern 
  European 
  regions 
  during 
  the 
  Silurian 
  

   period.

   (Abstract.) 
  

  

  The 
  author 
  discussed 
  in 
  detail 
  the 
  mineralogical 
  composition 
  of 
  each 
  

   of 
  the 
  fifteen 
  Donegal 
  granites, 
  and 
  described 
  the 
  method 
  usually 
  

   employed 
  by 
  him 
  in 
  solving 
  lithologico-chemical 
  problems, 
  coming 
  

   to 
  the 
  conclusion 
  that 
  nearly 
  half 
  of 
  these 
  granites 
  are 
  not 
  composed 
  

   altogether 
  of 
  the 
  four 
  minerals 
  (Quartz, 
  Ortboclase, 
  Oligoclase, 
  and 
  

   Black 
  Mica) 
  which 
  are 
  found 
  in 
  them 
  in 
  distinct 
  crystals, 
  and 
  that
