  On 
  the 
  Traces 
  of 
  a 
  Great 
  Ice-sheet 
  in 
  the 
  Southern 
  Part 
  of 
  

   the 
  Lake 
  District,

  After 
  a 
  few 
  introductory 
  remarks 
  on 
  roches 
  moutonnees, 
  the 
  dis- 
  

   tinction 
  between 
  primary 
  and 
  subsequent 
  stria?, 
  &c, 
  the 
  author 
  

   proceeds 
  to 
  consider 
  the 
  main 
  subject 
  of 
  his 
  paper 
  as 
  follows.] 
  

  

  A 
  tabular 
  statement 
  of 
  facts 
  will, 
  I 
  think, 
  clearly 
  show 
  that 
  the 
  

   primary 
  or 
  most 
  persistent 
  glaciation 
  of 
  the 
  south-central 
  part 
  of 
  

   the 
  Lake 
  District, 
  must 
  have 
  been 
  produced 
  by 
  an 
  ice-flow 
  capable 
  

   of 
  ignoring 
  the 
  drainage 
  of 
  the 
  country 
  to 
  a 
  much 
  greater 
  extent 
  

   than 
  could 
  have 
  resulted 
  from 
  any 
  system 
  of 
  confluent 
  glaciers 
  strictly 
  

   so 
  called.
