MR. RUMKER'S observations 



D. Comet in the Lion, July 1825. 



This Comet, which had been seen before in Europe, was discovered by me 

 on the 9th of July at Stargard, where I made the following observations 



Mean Places of the Stars for the Time of Comparison.

E. Great Comet of 1825. 



Of this Comet I shall give only my observations during those times when 

 its positions either became less favourable to European observers, or rendered 

 it invisible to them. During the remainder of its appearance it was very 

 generally observed, and with better instruments than I was provided with.
