  The 
  attempt 
  is 
  made 
  in 
  this 
  volume, 
  which 
  gives 
  the 
  empiric 
  

   formulas 
  of 
  67,000 
  derivatives 
  of 
  carbon, 
  to 
  combine 
  the 
  ele- 
  

   ments 
  successively 
  in 
  the 
  frequency 
  of 
  their 
  occurrence 
  with 
  

   carbon, 
  as 
  follows 
  : 
  H, 
  O, 
  X 
  ; 
  CI, 
  Br, 
  I, 
  F 
  ; 
  S, 
  P 
  ; 
  all 
  others 
  being 
  

   placed 
  in 
  alphabetical 
  order 
  : 
  A-Z. 
  The 
  arrangement 
  is 
  based 
  

   primarily 
  on 
  the 
  number 
  of 
  carbon 
  atoms, 
  and 
  then 
  on 
  the 
  num- 
  

   ber 
  of 
  elements 
  which 
  are 
  present 
  with 
  carbon 
  in 
  the 
  compounds. 
  

   It 
  is 
  believed 
  that 
  this 
  arrangement 
  will 
  aid 
  very 
  materially 
  the 
  

   research 
  student 
  and 
  others 
  who 
  are 
  frequently 
  obliged 
  to 
  ascer- 
  

   tain 
  quickly 
  and 
  briefly 
  the 
  characteristics 
  of, 
  and 
  to 
  examine 
  the 
  

   literature 
  relating 
  to, 
  any 
  one 
  carbon 
  derivative. 
  It 
  is 
  certain 
  

   that 
  the 
  author's 
  comprehensive 
  compilation 
  will 
  be 
  highly 
  appre- 
  

   ciated 
  by 
  every 
  chemist.

  — 
  This 
  considerable 
  volume 
  is 
  a 
  

   compendium 
  of 
  nearly 
  all 
  that 
  has 
  been 
  written 
  concerning 
  the 
  

   history, 
  physical 
  and 
  chemical 
  properties, 
  and 
  applications 
  of 
  the 
  

   famous 
  products 
  of 
  the 
  glass 
  manufactory 
  of 
  Schott 
  & 
  Co. 
  of 
  

   Jena. 
  Most 
  of 
  its 
  contents 
  has 
  already 
  appeared 
  in 
  various 
  

   journals 
  and 
  proceedings 
  of 
  learned 
  societies, 
  but 
  a 
  collection 
  of 
  

   this 
  work 
  into 
  a 
  single 
  volume 
  not 
  only 
  renders 
  it 
  far 
  more 
  con- 
  

   venient 
  of 
  access 
  but 
  it 
  must 
  come 
  to 
  all 
  readers 
  as 
  surprisingly 
  

   fresh 
  and, 
  above 
  all, 
  surprisingly 
  extensive. 
  

  

  A 
  brief 
  notice 
  of 
  the 
  chapters 
  which 
  deal 
  with 
  questions 
  not 
  at 
  

   all, 
  or 
  but 
  remotely, 
  connected 
  with 
  optics 
  may 
  conveniently 
  pre- 
  

   cede 
  a 
  somewhat 
  fuller 
  review 
  of 
  the 
  achievements 
  which 
  the 
  

   new 
  glasses 
  have 
  rendered 
  possible 
  to 
  the 
  practical 
  optician. 
  

  

  Chapters 
  vn 
  and 
  viii 
  are 
  devoted 
  to 
  the 
  mechanical 
  and 
  thermal 
  

   properties 
  of 
  glasses. 
  Their 
  topics
