  Memorandum 
  of 
  Observations 
  of 
  the 
  Solar 
  Eclipse 
  of 
  November 
  30th, 
  1 
  834, 
  made 
  at 
  the 
  

   University 
  of 
  Pennsylvania. 
  By 
  Edward 
  H. 
  Courtenay, 
  Professor 
  of 
  Mathematics 
  in 
  

   the 
  University 
  of 
  Pennsylvania. 
  

  

  During 
  one 
  or 
  two 
  hours 
  immediately 
  preceding 
  the 
  commencement 
  

   of 
  the 
  eclipse, 
  the 
  sun 
  was 
  frequently 
  obscured 
  by 
  clouds 
  ; 
  but 
  these, 
  

   although 
  not 
  entirely 
  dispersed, 
  had 
  disappeared 
  sufficiently 
  to 
  permit 
  

   a 
  very 
  satisfactory 
  observation 
  of 
  the 
  commencement. 
  For 
  several 
  

   seconds 
  (say 
  five 
  or 
  six) 
  previous 
  to 
  the 
  first 
  distinct 
  impression 
  on 
  the 
  

   sun's 
  disk, 
  a 
  slight 
  tremulous 
  motion 
  was 
  distinctly 
  observed 
  near 
  that
