REMARKS. 



No. Year. 



126. 1S23. Seen by several persons with the naked eye, in the last days 

 of December, and pointed out by them to the notice of as- 

 tronomers. Astr. Nachr. II. p. 455, III. First observed 

 at Prague the 30th Dec. 1823, and last by Wisniewski at 

 Petersburg-, the 28th March, 1824. The comet was parti- 

 cularly remarkable, from the 22d to the 31st January, in 

 having, besides the common tail opposite to the sun, another 

 pointed directly towards that luminary. Astr. Nachr. III. 

 p. 6, 27. Astr. Jahrb. Berl. 1827, p. 133. Gambart's Ob- 

 servations are in the Connaissance des T. 1827, p. 123. 

 [For the elements as computed by Taylor, Carlini, Brinkley, 

 and Richardson, see No. XVII of these Collections.] 



J 27. 1824. This comet, which was not seen in Europe, was discovered by 

 Rumker in New South Wales, and observed from the 15th 

 July to the 6th August. The observations might be re- 

 duced with greater accuracy ; and we may, perhaps, expect 

 additional ones from Sir Thomas Brisbane or Mr. Dunlop. 

 Astr. Nachr. IV. N. 78. p. 107. . . 



128. 1824. Discovered by Scheithammer at Chemnitz, the 23d July, by 



Pons the 24th July, by Gambart the 27th July, and by 

 Harding the 2nd August : observed last by Capocci at Naples 

 the 25th December. Astr. Nachr. III. p. 244, 257. IV. 

 N. 79. p. 123. Zach. Corr. Astr. X. vi. XII. i. This 

 comet was difficult to be observed, from its faint ness, and 

 from the indistinctness of its nucleus : it is also somewhat 

 uncertain whether the orbit was truly hyperbolic, as it ap- 

 peared to be, from the observations of the first months in 

 which it was visible. Encke computes the longitude of the 

 node from the mean equinox of 29th Sept. 1824. 



129. 1825. Discovered by Gambart the 19th May : observed until the end 



of June. Hitherto I am not acquainted with any other ob- 

 servations of this comet than those of Gambart, Schumacher, 

 Nicolai, Harding, and Olbers, most of which are printed in 

 the Astr. Nachr. IV. N. 81. The elements have some re- 

 semblance to those of the second comet of 1790, N. 93 ; but 

 they differ from them too much to allow us to suppose the 

 comets identical. Hansen and Clausen compute the longi- 

 tudes from the mean equinox of Jan. 1825.
