  of 
  Professor 
  

   Davis 
  on

  studying 
  for 
  a 
  num- 
  

   ber 
  of 
  years, 
  the 
  main 
  facts 
  and 
  theories 
  of 
  which 
  have 
  already 
  

   become 
  w^ell 
  known 
  to 
  geologists. 
  The 
  final 
  volume 
  is 
  beauti- 
  

   fully 
  illustrated,

  the 
  trap 
  and 
  the 
  

   sedimentary

  — 
  Mr. 
  Gilbert 
  elaborates 
  some 
  

   of 
  the 
  later 
  results 
  of 
  his 
  studies 
  of 
  the 
  earth 
  movements 
  as 
  affect- 
  

   ing 
  the 
  Lake 
  Regions. 
  He 
  has 
  shown 
  the 
  methods 
  of 
  recording 
  

   observations, 
  and 
  given 
  comparisons 
  of 
  movements 
  in 
  relation 
  to 
  

   Lake 
  levels, 
  and 
  has 
  drawn 
  together 
  the 
  various 
  observations 
  and 
  

   reduced 
  them 
  to 
  a 
  form 
  expressing 
  differential 
  movements 
  of 
  the 
  

   whole 
  region, 
  estimating 
  the 
  rate 
  and 
  direction 
  of 
  past 
  and 
  pres- 
  

   ent 
  movements.
