  that 
  the 
  ice 
  had 
  been 
  even 
  thicker 
  than 
  shown 
  by 
  these 
  marks. 
  

   Though 
  the 
  laws 
  of 
  motion 
  of 
  ice 
  were 
  the 
  same 
  as 
  those 
  of 
  water, 
  

   yet 
  the 
  action 
  of 
  a 
  hard 
  body 
  was 
  of 
  necessity 
  different 
  from 
  that 
  of 
  

   a 
  liquid. 
  

  

  Prof. 
  Eamsay 
  was 
  so 
  accustomed 
  to 
  meet 
  with 
  papers 
  such 
  as 
  

   this, 
  confirming 
  his 
  original 
  views, 
  that 
  he 
  was 
  almost 
  becoming 
  

   weary 
  of 
  the 
  subject. 
  He 
  considered, 
  however, 
  that 
  the 
  sections 
  

   given 
  by 
  the 
  author 
  on 
  a 
  true 
  scale 
  were 
  of 
  very 
  great 
  value, 
  as 
  

   calculated 
  to 
  give 
  a 
  correct 
  idea 
  of 
  the 
  actual 
  phenomena, 
  and 
  as 
  

   showing 
  the 
  value 
  of 
  De 
  la 
  Beche's 
  maxims 
  with 
  regard 
  to 
  such 
  

   diagrams. 
  He 
  inquired 
  whether 
  there 
  could 
  be 
  any 
  difficulty 
  in 
  a 
  

   body 
  of 
  ice, 
  some 
  thousands 
  of 
  feet 
  in 
  thickness, 
  cutting 
  out 
  such 
  

   inconsiderable 
  hollows 
  as 
  those 
  shown, 
  just 
  in 
  the 
  same 
  manner 
  as 
  

   running 
  water 
  sometimes 
  excavates 
  its 
  channel 
  more 
  deeply 
  at 
  one 
  

   spot 
  than 
  another, 
  if 
  from 
  local 
  circumstances 
  the 
  nature 
  of 
  its 
  

   motion 
  is 
  increased.
