tint (not as when one says Lyra is a bluish star, &c.), but a 

 positive and evident blue, between indigo-blue and verditer 

 green. It is about 12" in diameter, exactly round, or a 

 very little elliptic, and quite as sharply defined as a planet. 

 Its place is ll h 42 m K.A., and 146 14' N.P.D. My review 

 for double stars goes on in moonlight nights, and among 

 them I may mention y Lupi and e Chameleontis as among 

 the closest and most interesting. 



I have been hunting for Halley's comet by Riimker's 

 Ephemeris in Taurus, but without success, though in the 

 finest sky, quite dark, and with a newly-polished mirror. 

 (By the way, I should mention that I have not had the 

 least difficulty in my polishing work, and my mirrors are 

 now more perfect than at any former time since I have used 

 them.) My last comet hunt was Feb. 18. I shall, how- 

 ever, continue to look out for it. Pray mention this to 

 Schumacher, who is Kiimker's next-door neighbour. 



MISS HERSCHEL TO A. DE MORGAN, ESQ., SECRETARY OF 

 ROYAL ASTRONOMICAL SOCIETY. 



March 9, 1835. 



SIR,-- 



I return you many thanks for your communication of 

 being chosen an Honorary Member of the Royal Astro- 

 nomical Society, and beg you will do me the favour to 

 convey my most heartfelt thanks to the honourable gentle- 

 men of the Council for conferring so great an honour on 

 me ; and only regret that at the feeble age of 85 I have no 

 hope of making myself deserving of the great honour of 

 seeing my name joined with that of the much distinguished 

 Mrs. Somerville. 



I beg you will believe me to remain, with great regard, 

 Sir, your most respectful and 



obliged humble servant, 



CAROLINE HERSCHEL.
