  Stansfield 
  and 
  Nagaoka 
  and 
  Takamine 
  have 
  taken 
  their 
  

   measurements 
  from 
  the 
  satellite 
  of 
  shortest 
  wave-length 
  as 
  

   being 
  a 
  good 
  reference 
  line. 
  Table 
  II. 
  (p. 
  372) 
  gives 
  the 
  

   distances 
  of 
  the 
  satellites 
  from 
  this 
  line. 
  

  

  The 
  table 
  shows 
  that 
  the 
  greatest 
  discrepancies 
  occur 
  in 
  

   the 
  case 
  of 
  the 
  central 
  line. 
  The 
  values 
  for 
  the 
  other 
  com- 
  

   ponents 
  are 
  in 
  fairly 
  good 
  agreement, 
  although 
  McLennan' 
  s 
  

   values 
  seem 
  too 
  high 
  throughout. 
  It 
  will 
  be 
  noticed, 
  

   however, 
  that 
  the 
  relative 
  brightnesses 
  vary 
  greatly. 
  Our 
  

   component 
  no. 
  (2) 
  at 
  — 
  *187 
  was 
  clear 
  and 
  well 
  defined, 
  

   while 
  no. 
  (7) 
  at 
  +*174 
  was 
  faint 
  but 
  fairly 
  well 
  defined. 
  

   The 
  existence 
  of 
  these 
  lines 
  was 
  verified 
  by 
  the 
  methods 
  

   suggested 
  by 
  Stansfield*, 
  and 
  we 
  are 
  confident 
  that 
  they 
  are 
  

   both 
  real. 
  If 
  measured 
  from 
  the 
  position 
  of 
  Nagaoka 
  and 
  

   Takamine's 
  brightest 
  component 
  of 
  the 
  resolved 
  main 
  line,
