N. B. To find the equations in Table 14,-seek the Sun's de'clination to the nearest degree in the top line of the table; then, under this declination and against the given Lon. in the left hand column, is found the equation for Lon. and in the same column with the dec. and against the given time from Noon, in the right hand column, is found the equation for time; both which equations must be added, or subtracted, according to the directions at the head of the Table.

2d Required the Sun's Declination on the 1st of May, 1811, at 5 h. 48 min. P. M. in Longitude 720 W.

Dec. May 1st, 1811, table 13. = 140 53′ N.

When Sun's dec. increases. When Sun's dec. decreases.
