   physics, 
  died 
  on 
  April 
  4 
  in 
  his 
  eighty-seventh 
  year. 
  He 
  was 
  a 
  

   man 
  of 
  rare 
  genius, 
  energy 
  and 
  originality, 
  as 
  shown 
  by 
  his 
  early 
  

   discovery 
  of 
  thallium 
  with 
  the 
  spectroscope 
  and 
  his 
  valuable 
  

   work 
  in 
  the 
  same 
  line 
  ; 
  also 
  by 
  his 
  invention 
  of

  radiometer, 
  

   and 
  his 
  study 
  of 
  high 
  vacua 
  and

  phenomena 
  of 
  cathode 
  rays. 
  

   He 
  was 
  further 
  interested 
  in 
  psychic 
  phenomena 
  and 
  as 
  a 
  proof 
  

   of 
  his 
  activity 
  in 
  other 
  fields 
  must 
  be 
  mentioned 
  the 
  fact 
  that 
  

   the 
  well-known 
  Chemical 
  News 
  was 
  started 
  by 
  him 
  in 
  1859 
  and 
  

   he 
  remained 
  its 
  editor 
  and 
  proprietor 
  to 
  the 
  end 
  of 
  his 
  life. 
  

  

  M. 
  Jacques

   and 
  editor 
  of

  Dr.

  M. 
  Lambe, 
  the 
  well-known 
  paleontologist

  Geological

  of 
  Canada, 
  died 
  recently 
  in 
  his 
  fifty-sixth 
  

   year.

  draughtsman 
  to 
  Professor

  of 
  the

  in 
  1884. 
  In 
  1896 
  he 
  published 
  a 
  book 
  on 
  the 
  Atlantic 
  

   Coast 
  sponges, 
  and 
  later 
  did 
  considerable 
  work 
  on 
  the 
  Paleozoic 
  

   corals 
  of 
  Canada. 
  The 
  greater 
  part 
  of 
  his 
  work, 
  however, 
  had 
  to 
  

   do 
  with 
  fossil 
  vertebrates, 
  and 
  chiefly 
  with 
  the 
  large 
  dinosaurs 
  of 
  

   the 
  Ked 
  River 
  valley 
  of
