ELEMENTS OF COMET II. 1854. 

 [From the Monthly Notices of the Royal Astronomical Society, Vol. xiv. (1854).] 



PROBABLY you will have plenty of elements of the comet which is 

 now starring it, nevertheless I may mention the following, which I deduced 

 from Professor Challis's observations on March 30, April 1, 3. A comparison 

 of these elements with an observation on April 7, gave an error of only 

 10" in longitude, and nothing in latitude, so that they are probably not 

 far from the truth. 



Perihelion Passage, March 24'01221, G. M. T.

Longitude of the Ascending Node 315 29 52
