  Notices 
  respecting 
  New 
  Books. 
  

  

  The 
  remainder 
  of 
  the 
  book 
  is 
  devoted 
  to 
  the 
  consideration 
  of 
  

   more 
  complicated 
  cases 
  of 
  systems 
  of 
  a 
  single 
  component. 
  

  

  In 
  his 
  treatment 
  of 
  the 
  subject, 
  the 
  author 
  avoids, 
  as 
  far 
  as 
  

   possible, 
  the 
  use 
  of 
  higher 
  mathematics 
  and 
  the 
  more 
  difficult 
  

   parts 
  of 
  thermodynamics, 
  his 
  primary 
  aim 
  being 
  to 
  furnish 
  

   chemists 
  with 
  a 
  clear 
  account 
  of 
  the 
  present 
  state 
  of 
  the 
  theory 
  

   of 
  equilibria. 
  

  

  The 
  treatment 
  of 
  systems 
  of 
  two 
  components 
  is 
  promised 
  in 
  

   Part 
  II., 
  and 
  of 
  systems 
  of 
  three 
  or 
  more 
  components 
  in 
  Part 
  III. 
  

  

  Outlines 
  of 
  Electrochemistry.

  Harry 
  C. 
  Jones, 
  Associate-

  of 
  Physical 
  Chemistry 
  in 
  the 
  Johns 
  Hopkins 
  University, 
  

   New

   We 
  know 
  of 
  no 
  other 
  book 
  which 
  contains, 
  within 
  so 
  short 
  a 
  

   compass, 
  so 
  clear 
  an 
  account 
  of 
  the 
  leading 
  ideas 
  of 
  modern 
  

   electrochemistry. 
  The 
  author 
  is 
  an 
  enthusiast, 
  and 
  unmistakable 
  

   evidences 
  of 
  this 
  appear 
  on 
  almost 
  every 
  page 
  of 
  the 
  book, 
  which 
  

   forms 
  delightful 
  reading. 
  No 
  attempt 
  is 
  made 
  to 
  present 
  the 
  reader 
  

   with 
  an 
  exhaustive 
  and 
  systematic 
  account 
  of 
  the 
  subject, 
  but 
  the 
  

   method 
  followed 
  will, 
  we 
  venture 
  to 
  think, 
  furnish 
  him 
  with 
  a 
  

   much 
  clearer 
  conception 
  of 
  modern 
  electrochemical 
  theories 
  than 
  

   could 
  be 
  derived 
  from 
  the 
  study 
  of 
  more 
  elaborate 
  treatises. 
  The 
  

   subjects 
  dealt 
  with 
  comprise 
  osmotic 
  pressure, 
  electrolytic 
  dis- 
  

   sociation, 
  electrolysis 
  and 
  theories 
  of 
  electrolysis, 
  conductivity 
  of 
  

   solutions, 
  and 
  calculation 
  of 
  electromotive-forces 
  of 
  cells. 
  It 
  is 
  

   very 
  unfortunate 
  that 
  the 
  author 
  should 
  use 
  the 
  terms 
  " 
  tension 
  " 
  

   and 
  " 
  solution-tension 
  " 
  for 
  " 
  pressure 
  " 
  and 
  solution-pressures. 
  

   The 
  absurdity 
  of 
  using 
  " 
  tension 
  " 
  in 
  this 
  sense 
  has 
  repeatedly 
  

   been 
  pointed 
  out 
  ; 
  yet 
  chemists 
  are 
  great 
  sinners 
  in 
  this 
  respect. 
  

   Again, 
  why 
  should 
  electrochemists 
  arbitrarily 
  seize 
  upon 
  the 
  much- 
  

   abused 
  " 
  7r 
  " 
  and 
  make 
  it 
  do 
  duty 
  for 
  " 
  P.D. 
  " 
  ? 
  Why 
  not 
  use 
  

   symbols 
  commonly 
  employed 
  by 
  electricians 
  ? 
  On 
  p. 
  83, 
  foot 
  of 
  

   second 
  column, 
  the 
  printer 
  has 
  made 
  havoc 
  of 
  the 
  author's 
  

   meaning. 
  Apart 
  from 
  these 
  and 
  one 
  or 
  two 
  other 
  minor 
  blemishes, 
  

   we 
  have 
  little 
  fault 
  to 
  find 
  with 
  the 
  book, 
  and 
  can 
  heartily 
  

   commend 
  it 
  for 
  its 
  general 
  excellence.

  In 
  order 
  to 
  enable 
  its 
  members 
  to 
  keep 
  in 
  touch 
  with 
  contemporary 
  

  

  scientific 
  literature, 
  the 
  Deutsche 
  Physikalische 
  Gesellschaft 
  has 
  

  

  decided 
  to 
  issue 
  a 
  classified 
  fortnightly 
  register 
  of 
  all 
  articles 
  dealiug 
  

  

  with 
  physical 
  subjects 
  (including 
  meteorology) 
  in 
  various 
  languages. 
  

  

  We 
  have 
  before 
  us 
  the 
  first 
  two 
  numbers 
  of 
  this 
  new 
  publication, 
  

  

  which 
  for 
  purposes 
  of 
  reference 
  should 
  prove 
  very 
  important. 
  

  

  Considerable 
  care 
  appears 
  to 
  have 
  been 
  bestowed 
  on 
  the 
  classification 
  

  

  of 
  the 
  articles 
  under 
  suitable 
  headings.
