384 Celestial Phenomena, October 1826 — January 1827. 



The preceding numbers will enable any person to find the positions of 

 the planets, to lay them down upon a globe, and determine their times of 

 rising and setting. 



The following elements and results for the lunar eclipse of November, 

 have been calculated with the utmost care, from the tables of the sun by 

 Delambre, and the lunar tables of Burg ; they agree very precisely with 

 the times given in the Nautical Almanack, from Burkhardt's tables : 

 Apparent time of opposition at Greenwich, 14th November,

The following table presents the results of the calculation in which the 

 diameter of the shadow has been increased -^ for the refraction of the 

 earth's atmosphere. The alterations of diameter, equations of time, &c 

 have been carefully attended to, and the longitude of Edinburgh reckoned 

 12' 41".4 W- in time. 



• These results differing from the Nautical Almanack, the first about 1J", the 

 second about 1", I took much trouble to find an error in my computation, but in vain ; 

 nnd having compared several numbers of the Nautical Almanack, Conn, des Temt,
