  versity, 
  rendered 
  them 
  easy, 
  notwithstanding 
  the 
  unfavourable 
  condi- 
  

   tion 
  of 
  the 
  weather. 
  The 
  place 
  of 
  observation 
  was 
  north 
  of 
  the 
  Col- 
  

   lege 
  buildings. 
  It 
  will 
  be 
  seen 
  that 
  the 
  results 
  here 
  obtained 
  accord 
  

   very 
  well 
  with 
  the 
  deductions 
  from 
  numerous 
  observations 
  at 
  New- 
  

   port, 
  which 
  is 
  about 
  thirty 
  miles 
  south 
  of 
  Providence. 
  

  

  In 
  crossing 
  from 
  Providence 
  to 
  Albany, 
  N. 
  Y., 
  one 
  of 
  us 
  observed 
  at 
  

   Springfield, 
  Mass., 
  seventy-five 
  miles 
  west 
  from 
  the 
  former 
  place. 
  The 
  

   place 
  of 
  observation 
  was 
  highly 
  favourable, 
  being 
  in 
  an 
  open 
  field, 
  re- 
  

   mote 
  from 
  buildings, 
  and 
  well 
  shaded 
  from 
  the 
  sun. 
  

  

  At 
  Albany 
  the 
  place 
  of 
  observation 
  was 
  less 
  favourable, 
  being 
  in- 
  

   closed 
  by 
  buildings. 
  

  

  The 
  results 
  are 
  given 
  in 
  the 
  following 
  table.
