To show that the same calculations are applicable for other times, we
will make the calculation for the _centre ascending_, for the 22d
December, 1852, taking the following elements:
Moon's mer. passage, Dec. 22d 15h. 16m. G. time.
" right ascension, same time 51d 57'
" declination north 15 42
" true S. Diameter 886.6"
" distance from node 37
" " " quadrature 52
--------
Which gives the arc AR 29 5
1st correction -1 51
2d +1 11
--------
Corrected arc AQ 28 25
--------
And the latitude at the time of the meridian passage = 42d north, or
about forty miles north of Ottawa.
