6. Extract of a letter from A. Abbott, Esq., containing remarks 

 on the Comet as seen at Madeira, accompanied by two drawings. 

 Communicated by Sir John Herschel. 



7. Observations of the Comet by Captain P. P. King, R.N., made 

 at Port Stephens, New South Wales. Communicated by Captain 

 Beaufort, R.N. 



The tail of the comet was first seen at Port Stephens on the 2nd 

 of March, producing great alarm among the natives. 



On the 3rd it was again seen, and a second ray was observed ex- 

 tending obliquely from it, and making with it an angle of 10°. 



On the 4th, the nucleus was observed with an achromatic telescope 

 when about 8° above the horizon. It appeared like a reddish stellar 

 spot, the limbs well defined, and about 1' in diameter by estimation. 

 On this evening and the following, distances of the comet from 

 neighbouring stars were measured with the sextant.
