The letter to the Astronomer Royal, announcing the discovery of her second comet, has been preserved, with his answer.
MISS HERSCHEL TO THE REV. DR. MASKELYNE.
Last night, December 21st, at 7h 45', I discovered a comet, a little more than one degree south preceding β Lyræ. This morning, between five and six, I saw it again, when it appeared to have moved about a quarter of a degree towards δ of the same constellation. I beg the favour of you to take it under your protection.
Mrs. Herschel and my brothers join with me in compliments to Mrs. Maskelyne and yourself, and I have the honour to remain,
Dear sir,
Your most obliged, humble servant,
Carolina Herschel.
P.S.—The comet precedes β Lyræ 7' 5" in time, and is in the parallel of the small star (β being double). See fifth class, third star, of my catalogue.—Wm. H.
