  MR 
  WILLIAM 
  SWAN 
  ON 
  THE 
  

  

  by 
  the 
  fact, 
  that 
  the 
  moon 
  was 
  seen 
  by 
  degrees 
  to 
  cover 
  those 
  which 
  were 
  situated 
  

   on 
  the 
  side 
  towards 
  which 
  it 
  was 
  moving, 
  while 
  it 
  as 
  gradually 
  exposed 
  those 
  on 
  

   the 
  other 
  side. 
  

  

  Of 
  all 
  the 
  phenomena 
  of 
  the 
  eclipse, 
  there 
  is 
  none 
  on 
  which 
  the 
  testimony 
  of 
  

   the 
  observers 
  is 
  more 
  unanimous, 
  than 
  it 
  is 
  regarding 
  this 
  ; 
  and 
  there 
  is 
  certainly 
  

   none 
  which, 
  at 
  the 
  time, 
  seemed 
  to 
  me 
  more 
  striking 
  and 
  beautiful, 
  or 
  which 
  is 
  

   now 
  more 
  strongly 
  impressed 
  on 
  my 
  memory. 
  

  

  The 
  only 
  observer 
  whose 
  testimony 
  is 
  decidedly 
  opposed 
  to 
  the 
  fact, 
  that 
  the 
  

   moon 
  occulted 
  the 
  prominences 
  on 
  one 
  side, 
  and 
  disclosed 
  them 
  on 
  the 
  other, 
  is 
  

   Mr 
  Dunkin, 
  who 
  watched 
  the 
  hook-shaped 
  prominence 
  for 
  more 
  than 
  a 
  minute, 
  

   without 
  perceiving 
  the 
  slightest 
  change 
  in 
  its 
  appearance. 
  " 
  It 
  seemed 
  to 
  me," 
  he 
  

   remarks, 
  " 
  from 
  the 
  excessive 
  steadiness 
  of 
  this 
  prominence, 
  and 
  from 
  the 
  fact 
  

   that 
  I 
  had 
  zealously 
  watched 
  it 
  for 
  so 
  long 
  an 
  interval 
  without 
  its 
  undergoing 
  

   any 
  change, 
  that 
  this 
  object 
  had 
  some 
  connexion 
  with 
  the 
  moon." 
  He 
  adds, 
  

   however, 
  " 
  as 
  my 
  observations 
  have 
  been 
  all 
  made 
  under 
  rather 
  difficult 
  circum- 
  

   stances, 
  it 
  is 
  possible 
  I 
  may 
  be 
  deceived."* 
  

  

  In 
  opposition 
  to 
  this 
  observation, 
  we 
  have 
  the 
  testimony 
  of 
  a 
  large 
  number 
  

   of 
  persons 
  who 
  saw 
  the 
  moon 
  gradually 
  occult 
  those 
  prominences 
  which 
  were 
  

   situated 
  on 
  the 
  sun's 
  eastern 
  limb, 
  while 
  those 
  on 
  the 
  western 
  limb 
  were 
  gradually 
  

   elongated 
  ; 
  and, 
  in 
  some 
  instances, 
  additional 
  ones 
  were 
  seen 
  on 
  the 
  west 
  side, 
  

   towards 
  the 
  end 
  of 
  the 
  eclipse, 
  which 
  were 
  not 
  visible 
  at 
  the 
  beginning. 
  

  

  Thus 
  Mr 
  Jackson 
  states, 
  that 
  " 
  on 
  a 
  second 
  view, 
  a 
  little 
  before 
  the 
  sun 
  re- 
  

   appeared, 
  a 
  fourth 
  prominence 
  shewed 
  itself 
  at 
  about 
  45° 
  from 
  the 
  vertex 
  towards 
  

   the 
  west, 
  and 
  the 
  other 
  prominences, 
  especially 
  the 
  hook-shaped 
  one, 
  were 
  elon- 
  

   gated."! 
  M 
  r 
  Stephenson 
  remarks, 
  that 
  the 
  large 
  hook-shaped 
  prominence 
  " 
  in- 
  

   creased 
  in 
  size 
  ver}>- 
  rapidly, 
  and 
  then, 
  other 
  two 
  rose-coloured 
  prominences, 
  one 
  on 
  

   the 
  right 
  and 
  the 
  other 
  on 
  the 
  left, 
  started 
  out." 
  " 
  These 
  red 
  prominences 
  began 
  

   as 
  red 
  specks, 
  which 
  almost 
  immediately 
  became 
  summits, 
  by 
  the 
  extension 
  below 
  

   into 
  bases4" 
  Mr 
  Lassell 
  says, 
  the 
  prominences 
  "were 
  evidently 
  belonging 
  to 
  

   the 
  sun 
  ; 
  for, 
  especially 
  on 
  the 
  western 
  side, 
  I 
  observed 
  that 
  the 
  moon 
  passed 
  over 
  

   them, 
  leaving 
  them 
  behind, 
  and 
  revealing 
  successive 
  portions 
  as 
  she 
  advanced. 
  I 
  

   observed 
  only 
  the 
  summit 
  of 
  one 
  on 
  the 
  western 
  side, 
  although 
  my 
  friends 
  in 
  the 
  

   adjoining 
  room 
  had 
  seen 
  two. 
  The 
  moon 
  had 
  covered 
  one, 
  and 
  probably 
  three 
  

   fourths 
  of 
  the 
  other, 
  while 
  I 
  was 
  engaged 
  in 
  registering 
  the 
  time, 
  and 
  making 
  my 
  

   observations 
  with 
  the 
  naked 
  eye."§ 
  Mr 
  Williams 
  saw 
  " 
  two 
  conical 
  redpromi- 
  

   nences 
  on 
  the 
  following 
  or 
  east 
  limb 
  ;" 
  and, 
  " 
  as 
  the 
  moon 
  advanced, 
  she 
  speedily 
  

   covered 
  these." 
  He 
  again 
  states, 
  that 
  " 
  as 
  the 
  moon 
  progressed 
  and 
  left 
  it 
  be- 
  

   hind," 
  the 
  hook-shaped 
  prominence 
  on 
  the 
  west 
  side 
  " 
  increased 
  in 
  size 
  and 
  

   brilliancy.") 
  Mr 
  Stannistreet 
  says, 
  the 
  same 
  prominence 
  " 
  appeared 
  to 
  alter
