  (~XF 
  the 
  many 
  names 
  associated 
  with 
  the 
  development 
  of 
  electrical 
  

   ^-^ 
  engineering 
  during 
  the 
  last 
  quarter 
  of 
  the 
  nineteenth 
  century, 
  

   that 
  of 
  John 
  Hopkinson 
  claims 
  a 
  position 
  of 
  undisputed 
  and 
  

   honoured 
  pre-eminence. 
  Gifted 
  with 
  remarkable 
  ability 
  and 
  

   originality, 
  he 
  stood 
  head 
  and 
  shoulders 
  above 
  his 
  fellow-workers 
  

   as 
  the 
  man 
  of 
  genius 
  by 
  whose 
  unwearied 
  efforts 
  were 
  largely 
  

   built 
  up 
  those 
  general 
  scientific 
  principles 
  on 
  which 
  is 
  based 
  the 
  

   practice 
  of 
  modern 
  electrofechnology. 
  

  

  The 
  term 
  " 
  magnetic 
  circuit" 
  will 
  ever 
  be 
  associated 
  with 
  the 
  

   name 
  of 
  John 
  Hopkinson. 
  JNo 
  less 
  remarkable 
  than 
  his 
  technical 
  

   work 
  are 
  his 
  researches 
  in 
  pure 
  science. 
  John 
  Hopkinsou's 
  

   position 
  is 
  unique 
  in 
  that 
  he 
  was 
  the 
  first 
  to 
  convince 
  an 
  

   incredulous 
  school 
  of 
  engineers 
  that 
  a 
  thorough 
  training 
  in 
  pure 
  

   science 
  does 
  not 
  disqualify 
  a 
  man 
  from 
  grappling 
  with 
  the 
  problems 
  

   of 
  practical 
  engineering. 
  

  

  In 
  view 
  of 
  the 
  importance 
  and 
  variety 
  of 
  Hopkinson's 
  con- 
  

   tributions 
  to 
  both 
  pure 
  science 
  and 
  electrotei 
  hnology, 
  and 
  of 
  his 
  

   restless 
  mental 
  activity, 
  the 
  events 
  of 
  his 
  outward 
  life 
  strike 
  one 
  

   as 
  being 
  singularly 
  calm 
  and 
  peaceful. 
  If 
  we 
  except 
  his 
  tragical 
  

   death, 
  there 
  seems 
  to 
  be 
  nothing 
  in 
  his 
  career 
  which 
  could 
  arouse 
  

   the 
  interest 
  of 
  the 
  general 
  public, 
  or 
  appeal 
  to 
  the 
  student 
  of 
  

   human 
  nature. 
  Life 
  for 
  him 
  seems 
  to 
  have 
  spelt 
  success. 
  At 
  no 
  

   stage 
  in 
  his 
  brilliant 
  progress 
  to 
  the 
  head 
  of 
  his 
  profession 
  does 
  

   he 
  appear 
  to 
  have 
  met 
  with 
  serious 
  disappointment, 
  or 
  to 
  have 
  

   known 
  its 
  bitterness. 
  Adverse 
  circumstances 
  appeared 
  to 
  have 
  no 
  

   power 
  in 
  the 
  face 
  of 
  such 
  brilliant 
  endowments 
  as 
  those 
  which 
  

   nature 
  had 
  bestowed 
  on 
  John 
  Hopkinson. 
  It 
  seemed 
  as 
  though 
  

   everything 
  he 
  laid 
  his 
  hand 
  to 
  was 
  bound 
  to 
  succeed. 
  

  

  It 
  is 
  only 
  fitting 
  that 
  his 
  papers 
  should 
  be 
  published 
  in 
  collected 
  

   form 
  by 
  the 
  Cambridge 
  University 
  Press. 
  A 
  most 
  interesting 
  

   memoir 
  is 
  contributed 
  by 
  Mr. 
  B. 
  Hopkinson. 
  

  

  This 
  is 
  not 
  the 
  place 
  to 
  attempt 
  any 
  detailed 
  review 
  cf 
  

   John 
  Hopkinson's 
  work. 
  The 
  sterling 
  value 
  and 
  permanent 
  

   quality 
  of 
  that 
  work 
  are 
  well 
  known 
  to 
  all 
  students 
  of 
  physical 
  

   science, 
  and 
  his 
  'Original 
  Papers' 
  will 
  find 
  their 
  place 
  among 
  

   the 
  classical 
  works 
  in 
  this 
  branch 
  of 
  science. 
  

  

  The 
  publishers 
  deserve 
  great 
  credit 
  for 
  the 
  beautiful 
  " 
  get-up 
  " 
  

   of 
  these 
  two 
  volumes, 
  the 
  first 
  of 
  which 
  is 
  embellished 
  with 
  two 
  

   portraits 
  of 
  John 
  Hopkinson, 
  at 
  the 
  ages 
  of 
  twenty-three 
  and 
  

   forty-eight 
  respectively.
