  an 
  active 
  part

  furthering 
  her 
  schemes

  the 
  ameliora- 
  

   tion

  the

   Together 
  they 
  have 
  long 
  exercised 
  a 
  gracious 
  hospitality, 
  which 
  has 
  caused 
  

   their 
  house 
  to 
  be 
  a 
  pleasant 
  place 
  of 
  reunion, 
  not 
  only 
  for 
  persons 
  eminent 
  

   in 
  literature, 
  science, 
  or 
  politics, 
  but 
  also 
  for 
  younger 
  men, 
  who 
  had 
  yet 
  to 
  

   make 
  good 
  their 
  position, 
  and 
  were 
  often 
  aided 
  to 
  do 
  so 
  by 
  the 
  encourage- 
  

   ment 
  they 
  there 
  received. 
  Few 
  will 
  be 
  more 
  missed 
  than 
  Gustaf 
  Ketzius. 
  

   But, 
  although 
  his 
  name 
  is 
  now 
  only 
  a 
  memory, 
  it 
  is 
  the 
  memory 
  of 
  a 
  genial 
  

   personality, 
  of 
  an 
  accurate 
  scientific 
  observer, 
  and 
  of 
  a 
  valued 
  friend.

  LUDIMAB 
  HEBMANN, 
  1838-1914. 
  

  

  Ludimar 
  Hermann 
  was 
  born 
  in 
  Berlin 
  in 
  1838. 
  He 
  appears 
  to 
  have 
  learned 
  

   to 
  read 
  at 
  the 
  age 
  of 
  three 
  years 
  and 
  showed 
  inclinations 
  towards 
  a 
  scientific 
  

   career 
  at 
  an 
  early 
  age. 
  He 
  attended 
  courses 
  in 
  Natural 
  Science 
  and 
  

   Medicine 
  at 
  the 
  University 
  of 
  his 
  native 
  town, 
  and 
  after 
  some 
  interrup- 
  

   tions 
  by 
  duties 
  as 
  medical 
  officer 
  in 
  the 
  wars 
  of 
  1859 
  and 
  1864, 
  he 
  became 
  

   assistant 
  to 
  Du 
  Bois 
  Beymond. 
  Owing 
  to 
  the 
  position 
  Hermann 
  took 
  up 
  

   with 
  regard 
  to 
  the 
  nature 
  of 
  the 
  electrical 
  phenomena 
  in 
  muscle, 
  to 
  be 
  

   referred 
  to 
  presently, 
  his 
  relations 
  witli 
  the 
  professor 
  became 
  somewhat 
  

   strained, 
  and 
  in 
  1868 
  he 
  was 
  elected 
  to 
  the 
  Chair 
  of 
  Physiology 
  in 
  the 
  

   University 
  of 
  Zurich. 
  He 
  remained 
  in 
  this 
  position 
  until 
  1884, 
  when 
  he 
  

   was 
  called 
  to 
  Konigsberg. 
  A 
  busy 
  life 
  of 
  investigation 
  and 
  scientific 
  

   activities 
  of 
  a 
  more 
  public 
  nature 
  occupied 
  his 
  time 
  to 
  the 
  full 
  until 
  the 
  year 
  

   1909, 
  in 
  which 
  he 
  was 
  attacked 
  by 
  an 
  intestinal 
  growth, 
  which 
  necessitated 
  

   several 
  operations, 
  by 
  which 
  cure 
  was 
  apparently 
  effected. 
  He 
  retired 
  from 
  

   his 
  chair 
  ; 
  however, 
  four 
  years 
  later 
  and 
  a 
  year 
  afterwards 
  the 
  disorder 
  

   returned, 
  developed 
  rapidly 
  and 
  resulted 
  in 
  his 
  death 
  on 
  June 
  5, 
  1914, 
  when 
  

   he 
  had 
  reached 
  the 
  age 
  of 
  nearly 
  76 
  years. 
  

  

  It 
  was 
  Hermann's 
  fortune 
  to 
  be 
  concerned 
  with 
  the 
  investigation 
  of 
  

   certain 
  problems 
  in 
  physiology 
  which 
  were 
  much 
  discussed 
  at 
  the 
  time. 
  

   Du 
  Bois 
  Beymond 
  had 
  propounded 
  the 
  view 
  that 
  the 
  electrical 
  currents 
  to 
  

   be 
  obtained 
  from 
  muscle 
  when 
  electrodes 
  are 
  placed, 
  one 
  on 
  a 
  natural 
  

   longitudinal 
  surface, 
  the 
  other 
  on 
  a 
  cross-section, 
  are 
  to 
  be 
  accounted 
  for 
  

   by 
  the 
  presence 
  of 
  a 
  series 
  of 
  " 
  electromotive 
  molecules," 
  positive 
  in 
  the 
  

   middle, 
  negative 
  at 
  both 
  ends, 
  arranged 
  in 
  Tegular 
  order. 
  The 
  existence 
  of 
  

   such 
  permanent 
  structures 
  was 
  disproved 
  by 
  Hermann 
  when 
  he 
  showed 
  by 
  

   careful 
  experiments 
  that 
  an 
  uninjured 
  muscle 
  is 
  equipotential 
  over 
  the
