MISS HERSCHEL TO SIR JOSEPH BANKS. _August, 17, 1797._ SIR,— This is not a letter from an astronomer to the President of the Royal Society announcing a comet, but only a few lines from Caroline Herschel to a friend of her brother’s, by way of apology for not sending intelligence of that kind immediately where they are due. I have so little faith in the expedition of messengers of all descriptions that I undertook to be my own, with an intention of stopping in town and write and deliver a letter myself, but unfortunately I undertook the task with only the preparation of one hour’s sleep, and having in the course of five years never rode above two miles at a time, the twenty to London, and the idea of six or seven more to Greenwich in reserve, totally unfitted me for any action. Dr. Maskelyne was so kind as to take some pains to persuade me to go this morning to pay my respects to Sir Joseph, but I thought a woman who knows so little of the world ought not to aim at such an honour, but go home, where she ought to be, as soon as possible. The letter which you sent, sir, to my brother, was the only one received at Slough in my absence; it arrived towards noon on the 16th, and was brought by a porter from an inn. I hope you will excuse the trouble I give by sending this, though I know it is entirely useless, because Dr. Maskelyne had probably my memorandum which I took to Greenwich with him when he called in Soho Square, and therefore I can say nothing but what you, sir, are acquainted with already; but I shall be a little more comfortable when I can say to my brother I have written to Sir J. Banks concerning the comet. With the utmost respect, I remain, sir, Your most obedient servant, C. HERSCHEL. [Sidenote: 1795-1797. _Ceases to reside with her Brother._]
