  simultaneously 
  like 
  a 
  coal. 
  The 
  distillate 
  is 
  dark 
  red 
  by 
  trans- 
  

   mitted 
  light 
  and 
  shows 
  a 
  decided 
  green 
  fluorescence. 
  For 
  sake 
  

   of 
  comparison 
  a 
  quantity 
  of 
  soft 
  coal 
  used 
  for 
  making 
  coal 
  gas 
  

   and 
  obtained 
  from 
  a 
  gas 
  works 
  was 
  distilled. 
  This 
  gave 
  a 
  

   more 
  tarry 
  distillate 
  but 
  less 
  in 
  amount 
  for 
  equal 
  weights 
  of 
  

   material. 
  The 
  odor 
  of 
  the 
  distillate 
  from 
  the 
  coal 
  was 
  markedly 
  

   different 
  from 
  that 
  from 
  the 
  asphalt 
  ; 
  it 
  lacked 
  also 
  the 
  green 
  

   fluorescence 
  of 
  the 
  distillate 
  from 
  the 
  asphalt. 
  The 
  coal 
  was 
  

   practically 
  insoluble 
  in 
  carbon 
  disulphide, 
  while 
  the 
  asphalt 
  was 
  

   soluble 
  to 
  the 
  extent 
  of 
  over 
  35 
  per 
  cent. 
  

  

  The 
  material, 
  all 
  things 
  considered, 
  resembles 
  albertite 
  more 
  

   than 
  any 
  other 
  of 
  the 
  asphalt 
  substances, 
  but 
  it 
  differs 
  from 
  it 
  

   too 
  in 
  certain 
  respects. 
  For 
  the 
  sake 
  of 
  comparison 
  the 
  data 
  

   contained 
  in 
  Dana's 
  Mineralogy 
  on

  Of 
  the 
  differences 
  between

  and 
  the 
  Tafl

  the 
  

   contrast 
  in 
  the

  is 
  perhaps 
  the 
  most 
  

   striking.
