near the lame fpot, he found its change of place to be very per- 

 ceptible. The following obfervations were tranfmitted by him 

 to Dr. Schroeter :

App. Dec. 11 52 59 N. 

 Dr. Olbers had not the means of obferving any difc, but Dr. 

 Schroeter, from his information, began to obferve it on the 

 30th with his thirteen feet reflector, while his affiftant, Mr. 

 Harding, determined its place. With a power of 288 of this 

 large inftrument, it appeared round and lefs hazy than Ceres, 

 with a diameter of 4.635 feconds, which is much larger than its apparent dia- 

 thofe of Ceres and the Georgium Sidus ; the former of which, meter larger thaa 



, -■ that of Ceres or 



on the 28th March, meafured 4.021 fee. and the latter, on the the Geo. Sidus. 



20th, meafured 3.973 feconds. Its light, though pale and white Its light. 



in comparifon with that of Ceres, was neverthelefs more in- 



tenfe upon the whole, as appeared by its projection on the 



difc micrometer; but the Georgium Sidus was much brighter. 



A minute ftar was feen near it on two feveral days, which Sufpictonof a 

 Dr. Schroeter feems to fiifpect as a fatellite. fateilite. 



The pofition of the Olberian planet (or comet), at March 

 30 d. 8 h. 20 m. 50 fee. mean time, was 



App. R. A. 184° 35' 52" and 12° 15' 8" app. N. declin. 



On the lft of April it was again obferved with the great No difc on 

 reflector, and appeared to exhibit no difc, but was lefs in a A P ril *■ 

 brighter light with the power of 288, and could not be diftin- 

 guiihed from a fixed ftar. When it fometimes appeared with 

 a difc, its diameter was only 3 ".244. The Doctor is difpofed 

 to afcribe this to the heavy dew.
