4. Notes on the Comet, accompanied by a Pencil Sketch, by Capt. 

 Hopkins, commanding the East India Company's Ship Seringapa- 

 tam, on a voyage from the Cape of Good Hope. Communicated by 

 Sir John Herschel. 



The comet was seen first on the 2nd of March, but indistinctly. 

 A good view of it was obtained on March 4, when it was very bril- 

 liant. Its tail appeared separated through half its length by a dark 

 line, and was, by rough measurement, found to be about 30° in 

 length. After this it decreased in brightness, and was not seen 

 longer than the 7 th of April.

The tail of the comet was first seen on the 6th of March ; the 

 nucleus was compared roughly with two small stars seen in the same 

 field with it on the 13th; on the 14th and 15th some observations 

 were obtained with an altitude and azimuth instrument, and it was 

 compared with some known stars ; the nucleus was not seen after

The tail was first seen on the 3rd of March, but a good view of it 

 was not obtained till the 9th. On this evening, the nucleus seen 

 in a night telescope appeared like a star of the sixth magnitude, and 

 the following distances from a Eridani and a Orionis were measured 

 with a sextant : —
