OTTOWA STORM, DECEMBER 22, 1852.

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.
