  — 
  This 
  little 
  book, 
  intended 
  for 
  young 
  pupil?, 
  gives 
  one- 
  

   hundred 
  exercises, 
  to 
  each 
  of 
  which 
  a 
  page 
  of 
  the 
  book 
  is 
  devoted, 
  

   a 
  blank 
  page 
  being 
  left 
  opposite 
  to 
  this 
  for 
  notes. 
  A 
  short 
  course 
  

   in 
  qualitative 
  analysis 
  is 
  included. 
  The 
  directions 
  given 
  for 
  

   experiments 
  are 
  generally 
  clear 
  and 
  illustrated 
  by 
  appropriate 
  

   cuts. 
  The 
  text 
  is 
  considerably 
  marred 
  by 
  the 
  use 
  of 
  many 
  abbre- 
  

   Yiations, 
  all 
  of 
  which 
  are 
  not 
  self-evident. 
  Pupils 
  using 
  this 
  book 
  

   would 
  require 
  much 
  aid 
  from 
  their 
  teacher, 
  as 
  equations 
  are 
  con- 
  

   tinually 
  required 
  although 
  none 
  are 
  given 
  in 
  the 
  book.

  — 
  This 
  is 
  a 
  very 
  interesting 
  discussion 
  of 
  the 
  conditions 
  

   required 
  for 
  successful 
  astronomical 
  work 
  at 
  high 
  altitudes, 
  fol- 
  

   lowed 
  by 
  an 
  account 
  of 
  the 
  chief 
  observatories 
  already 
  established 
  

   in 
  different 
  parts 
  of 
  the 
  world. 
  The 
  highest 
  of 
  these 
  is 
  the 
  observa- 
  

   tory 
  of 
  M. 
  Janssen 
  on 
  the 
  summit 
  of 
  Mt. 
  Blanc, 
  at 
  an 
  altitude 
  of 
  

   15,780 
  feet. 
  These 
  accounts 
  are 
  illustrated 
  by 
  a 
  large 
  number 
  

   of 
  excellent 
  and 
  interesting 
  plates.

  The 
  repub- 
  

   lication 
  of 
  these 
  essays, 
  which 
  originally 
  appeared 
  in 
  several 
  of 
  

   the 
  English 
  and 
  American 
  reviews, 
  will 
  recall 
  the 
  versatile 
  and 
  

   attractive 
  style 
  of 
  Romanes. 
  The 
  essays 
  deal 
  mainly 
  with 
  the 
  

   philosophical 
  aspects 
  of 
  biology 
  ; 
  they 
  are 
  worth 
  gathering 
  in 
  this 
  

   permanent 
  shape 
  because 
  of 
  the 
  importance 
  of 
  the 
  problems, 
  which 
  

   the 
  author 
  handled 
  with 
  rare 
  skill.
