  Discussion. 
  

  

  The 
  Peesieent 
  expressed 
  his 
  pleasure 
  at 
  hearing 
  a 
  paper 
  con- 
  

   taining 
  so 
  careful 
  a 
  chain 
  of 
  reasoning. 
  The 
  large 
  collection 
  of 
  

   implements 
  from 
  so 
  small 
  an 
  area 
  was 
  remarkable. 
  He 
  asked 
  

   whether 
  the 
  red 
  clay 
  might 
  not 
  be 
  a 
  subaerial 
  formation, 
  like 
  the 
  

   deposits 
  formed 
  in 
  such 
  dry 
  countries 
  as 
  Central 
  Asia. 
  

  

  Dr. 
  Evans 
  congratulated 
  Mr. 
  Harrison 
  on 
  the 
  discovery 
  of 
  the 
  

   magnificent 
  suite 
  of 
  specimens 
  exhibited. 
  The 
  find 
  was 
  one 
  of 
  much 
  

   novelty 
  on 
  account 
  of 
  the 
  position 
  of 
  the 
  implements, 
  and 
  the 
  

   Author's 
  suggestions 
  opened 
  out 
  new 
  and 
  original 
  views 
  There
