  Lezioni 
  Sjjerimentali 
  su 
  la 
  Luce 
  considerata 
  come 
  Fenomeno 
  

   Elettromagnetico. 
  By 
  A. 
  Garbasso, 
  Lecturer 
  in 
  the 
  University 
  of 
  

   Pisa. 
  Milan 
  : 
  Publishers 
  of 
  L 
  'Elettricitd, 
  1897. 
  

  

  In 
  1805 
  the 
  author 
  delivered 
  a 
  course 
  of 
  lectures 
  in 
  the 
  University 
  

   of 
  Turin, 
  on 
  light 
  considered 
  as 
  an 
  electromagnetic 
  phenomenon. 
  

   The 
  book 
  before 
  us 
  contains 
  an 
  account 
  of 
  the 
  experimental 
  

   portion 
  of 
  these 
  lectures 
  ; 
  it 
  deals 
  with 
  the 
  researches 
  of 
  Hertz 
  

   and 
  his 
  successors, 
  and 
  describes 
  the 
  principal 
  experiments 
  in 
  the 
  

   form 
  in 
  which 
  they 
  were 
  repeated 
  by 
  the 
  author 
  in 
  his 
  lectures. 
  

   The 
  volume 
  contains 
  over 
  100 
  illustrations, 
  the 
  majority 
  of 
  which 
  

   are 
  of 
  very 
  poor 
  quality 
  and 
  several 
  almost 
  unintelligible. 
  The 
  

   experiments 
  are 
  fairly 
  well 
  described, 
  but 
  the 
  work 
  suffers 
  greatly 
  

   by 
  the 
  omission 
  of 
  the 
  non-experimental 
  parts 
  of 
  the 
  subject.
