From the above observations Mr. Jacob infers the following place 

 of the comet : — 

 At 7 h 42 m Gr. M.T. R.A. = l h 17 m 9 s Decl. = — 11° 59'. 

 The nucleus was last seen on the 5th of April. 



9. Letter from T. Forster, Esq., dated Bruges, April 22, 1843. 

 Dr. Forster, with a view of drawing attention to the phenomena 



observed by him on the 20th of March in connexion with the comet, 

 had accurately represented in a coloured drawing the appearance 

 of the comet and of the surrounding sky, and had caused it to be 

 copied by an artist, with the intention of presenting the same to the 

 Society. The drawing has since been received, and is now in the 

 possession of the Society.

11. Letter from H. A. Cowper, Esq., H. M. Consul at Pernambuco 

 in Brasil, dated 9th March, 1843. 



The comet was seen first on March 1 ; and on the 4th Mr. Cowper 

 saw the nucleus very distinctly, and makes the following remarks on 

 its appearance : — 



" It is particularly small, without any nebulosity, but of extreme 

 brightness, of a golden hue, and a line of the same bright colour 

 may be distinctly traced running directly from it into the tail for 

 4° or 5° : the tail is perhaps 30° in length, and is of a brilliant silver 

 colour, perfectly opake, but becoming less and less dense until it is 

 lost in space." 



Mr. Cowper adds the following observations, made with a sex- 

 tant on March 9, at his request, by a master of a merchant vessel : 



Bearing of nucleus W. 7 45 S. 



Altitude of ditto 9 



Length of tail 28 



Breadth of tail at two-thirds of its length from the nucleus 1°.
