  2. 
  The 
  red 
  prominences 
  cannot 
  be 
  regarded 
  as 
  optical 
  phenomena, 
  produced 
  

   either 
  by 
  unequally 
  heated 
  strata 
  of 
  air, 
  or 
  by 
  the 
  action 
  of 
  the 
  moon's 
  limb 
  on 
  

   the 
  sun's 
  light 
  ; 
  for 
  these 
  hypotheses 
  are 
  inconsistent, 
  both 
  with 
  the 
  permanency 
  of 
  

   their 
  forms, 
  and 
  with 
  the 
  similarity 
  of 
  their 
  appearance 
  as 
  seen 
  from 
  stations 
  dif- 
  

   ferently 
  situated 
  in 
  the 
  moon's 
  shadow. 
  

  

  3. 
  The 
  discrepancies 
  in 
  the 
  observations 
  are 
  as 
  unfavourable 
  to 
  the 
  supposi- 
  

   tion 
  that 
  the 
  prominences 
  are 
  optical 
  phenomena, 
  as 
  to 
  the 
  hypothesis 
  that 
  they 
  

   are 
  material 
  objects 
  belonging 
  to 
  the 
  sun. 
  

  

  4. 
  The 
  observed 
  differences 
  in 
  the 
  numbers 
  and 
  appearance 
  of 
  the 
  prominences 
  

   as 
  seen 
  from 
  stations 
  differently 
  situated 
  in 
  the 
  moon's 
  shadow, 
  are, 
  upon 
  the 
  

   whole, 
  accordant 
  with 
  the 
  effects 
  which 
  parallax 
  would 
  produce, 
  if 
  they 
  existed 
  in 
  

   the 
  sun. 
  

  

  5. 
  The 
  hypothesis 
  that 
  the 
  prominences 
  exist 
  in 
  the 
  sun, 
  seems 
  to 
  afford 
  the 
  

   only 
  explanation 
  of 
  the 
  facts, 
  that 
  the 
  moon 
  gradually 
  occulted 
  them 
  on 
  one 
  side, 
  

   and 
  exposed 
  them 
  on 
  the 
  other, 
  while 
  their 
  outlines 
  remained 
  unaltered. 
  

  

  6. 
  On 
  these 
  grounds 
  it 
  is 
  inferred, 
  that 
  the 
  red 
  prominences 
  are 
  material 
  

   objects, 
  actually 
  belonging 
  to 
  the 
  sun.
