  its 
  shape 
  rapidly, 
  unfolding 
  more 
  and 
  more 
  of 
  the 
  curve, 
  as 
  the 
  phase 
  proceeded."* 
  

   Mr 
  Carrington 
  saw 
  a 
  small 
  pink 
  prominence 
  at 
  an 
  angle 
  of 
  100° 
  from 
  the 
  upper 
  

   limb 
  reckoned 
  towards 
  the 
  east 
  ; 
  it 
  was 
  of 
  the 
  form 
  of 
  a 
  hay-rick, 
  and 
  rapidly 
  di- 
  

   minished," 
  so 
  that 
  " 
  in 
  10 
  s 
  it 
  was 
  no 
  longer 
  seen 
  ;" 
  on 
  the 
  other 
  hand, 
  he 
  had 
  " 
  no 
  

   manner 
  of 
  doubt" 
  that 
  the 
  prominences 
  to 
  the 
  west 
  of 
  the 
  sun's 
  vertex 
  " 
  increased 
  

   in 
  size 
  so 
  as 
  to 
  be 
  five 
  times 
  as 
  large" 
  as 
  when 
  they 
  first 
  appeared. 
  He 
  afterwards 
  

   adds, 
  " 
  that 
  these 
  changes 
  are 
  fully 
  accounted 
  for 
  by 
  the 
  moon's 
  motion 
  ;" 
  and 
  he 
  

   concludes, 
  that 
  " 
  the 
  prominences 
  are 
  appendages 
  to 
  the 
  sun."f 
  Lieutenant 
  

   Pettersson 
  says, 
  that 
  the 
  movement 
  of 
  the 
  prominences 
  relatively 
  to 
  the 
  limb 
  

   of 
  the 
  moon, 
  and 
  above 
  all, 
  the 
  successive 
  removal 
  of 
  a 
  detached 
  prominence, 
  

   which 
  was 
  at 
  first 
  in 
  contact 
  with 
  it, 
  convinced 
  him 
  that 
  they 
  belong 
  to 
  the 
  sun.i; 
  

   According 
  to 
  Mr 
  Airy's 
  observations, 
  a 
  prominence 
  at 
  first 
  seen 
  to 
  the 
  east 
  

   " 
  disappeared, 
  the 
  moon 
  having 
  overlapped 
  it, 
  and 
  the 
  two 
  to 
  the 
  west, 
  which 
  

   touched 
  the 
  moon, 
  were 
  lengthened 
  ; 
  the 
  moon 
  evidently 
  having 
  uncovered 
  more 
  

   of 
  their 
  bases 
  ;" 
  while 
  the 
  detached 
  mass 
  " 
  was 
  further 
  removed 
  from 
  the 
  moon's 
  

   limb," 
  and 
  " 
  now 
  a 
  conical 
  prominence 
  came 
  into 
  sight" 
  at 
  about 
  60° 
  to 
  the 
  

   west, 
  measured 
  from 
  the 
  sun's 
  vertex." 
  " 
  Just 
  before 
  the 
  sun 
  reappeared 
  all 
  these 
  

   objects 
  were 
  still 
  further 
  lengthened 
  from 
  the 
  moon's 
  motion," 
  while 
  a 
  sierra 
  or 
  

   range 
  of 
  serrated 
  eminences 
  came 
  into 
  view." 
  § 
  Professor 
  Chevallier, 
  who 
  ob- 
  

   served 
  the 
  eclipse 
  with 
  the 
  high 
  power 
  of 
  180, 
  is 
  of 
  opinion 
  that 
  the 
  promi- 
  

   nences 
  " 
  were 
  certainly 
  connected 
  with 
  the 
  sun, 
  for 
  the 
  separation 
  of 
  the 
  edge 
  

   of 
  the 
  moon 
  from 
  them, 
  as 
  she 
  moved 
  onwards, 
  could 
  be 
  distinctly 
  seen."|| 
  Mr 
  

   Hind 
  estimated 
  the 
  height 
  of 
  the 
  hook-shaped 
  prominence 
  at 
  45", 
  about 
  20 
  s 
  after 
  

   the 
  sun 
  disappeared, 
  and 
  towards 
  the 
  end 
  of 
  the 
  totality 
  at 
  2' 
  ; 
  " 
  the 
  moon 
  having 
  

   apparently 
  left 
  more 
  and 
  more 
  of 
  it 
  visible, 
  as 
  she 
  travelled 
  across 
  the 
  sun." 
  

   There 
  was 
  no 
  change 
  in 
  the 
  form 
  of 
  this 
  object 
  ; 
  and 
  while 
  the 
  moon 
  moved 
  away 
  

   from 
  the 
  detached 
  prominence, 
  the 
  latter 
  "preserved 
  its 
  relative 
  position 
  1 
  '' 
  to 
  the 
  

   hook-shaped 
  one.^[ 
  Mr 
  Adie 
  says, 
  that 
  " 
  as 
  the 
  moon 
  advanced, 
  the 
  crescent," 
  or 
  

   hook-shaped 
  prominence 
  " 
  increased 
  in 
  altitude," 
  as 
  did 
  another 
  prominence 
  

   below 
  it 
  ; 
  while 
  that 
  " 
  to 
  the 
  eastern 
  side 
  diminished 
  to 
  less 
  than 
  one-half 
  the 
  

   altitude 
  it 
  had 
  when 
  first 
  observed 
  ;" 
  and 
  these 
  changes, 
  he 
  thinks, 
  afford 
  the 
  most 
  

   satisfactory 
  proof 
  " 
  that 
  the 
  prominences 
  belong 
  to 
  the 
  sun 
  and 
  not 
  to 
  the 
  moon."** 
  

   Mr 
  Dawes 
  states 
  that 
  the 
  height 
  of 
  the 
  hook-shaped 
  prominence 
  was 
  perhaps 
  l'-5 
  

   when 
  first 
  seen, 
  and 
  that 
  its 
  height 
  " 
  increased 
  to 
  two 
  minutes 
  or 
  more, 
  as 
  the 
  

   moon's 
  progress 
  revealed 
  it 
  more 
  entirely." 
  The 
  detached 
  prominence 
  " 
  was
