CIRCUM-MERIDIAN OBSERVATIONS TAKEN NEAR NOON. 231 



for every 10' of the sun's declination, both north and south 

 of the equator, with a column of differences, so that lean de- 

 termine, almost by inspection, the numbers for the interme- 

 diate minutes ; and this I would recommend to any one who 

 means to prosecute these observations for a considerable time, 

 or in a fixed observatory, as this Table is equally applicable 

 for the corrections of observations made on the fixed stars or 

 planets, whose declinations do not exceed the limits of the 

 Table ; otherwise it will be necessary to extend it to a greater 

 range in declination. By pursuing this simple process, I am 

 of opinion, that the latitude of any place may be determined 

 to within a few seconds from a single day's observations ; and I 

 have further discovered, that those taken at a distance from the 

 meridian afford just as satisfactory results as if they were taken 

 at the instant of noon ; and this I have confirmed by a variety 

 of trials.
