To this period of Miss Herschel’s life belongs a folio manuscript book, written with the utmost neatness, which she sent with one of her various consignments of papers to her nephew after her return to Hanover, and introduced as follows:— DEAR NEPHEW,— This is the fragment of a book which was too bulky for the portfolio in which I was collecting such papers as I wished might not fall into any other but your own hands. They contain chiefly answers of your father to the inquiries I used to make when at breakfast before we separated each for our daily tasks. [Sidenote: 1786-1787. _Employments at Slough._] The information is of a very miscellaneous kind, but matters connected with her special study form the greater part of the questions. For instance:— “Given the true time of the transit—take a transit. Do the same thing another way. To find what star Mercury is nearest. Take its place in the Nautical Almanac. Another way.... * * * * * Time of a star’s motion to be turned into space. * * * * * To adjust the quadrant when fastened to the telescope. * * * * * A logarithm given, to find the angle. Oblique spherical triangles.” _4th._—I wrote to-day to Hanover, booked my observations, and made a fair copy of three letters. Made accounts. The night is cloudy. _5th._—I calculated nebulæ all day. The night was tolerably fine, and I saw the comet. _6th._—I booked my observations of last night. Received a letter from Dr. Blagden in the morning, and in the evening Sir J. Banks, Lord Palmerston, and Dr. Blagden, came and saw the comet. The evening was very fine. _7th_, _8th_.—Booked my observations; was hindered much by being obliged to find a man to assist the smith. Dr. Lind and Mr. Cavallo came on the 8th, and Mr. Paradise in the afternoon, but the evening was cloudy. _9th._—I calculated 100 nebulæ.... _10th._—Calculated 100 nebulæ. The smith borrowed a guinea. He complains of Turner (the gardener), but we will, if possible, have patience till my brother returns. _11th._ I completed to-day the catalogue of the first thousand. _12th._ ... calculated 200 nebulæ of the second thousand. _13th._ Professor Kratzensteine, from Copenhagen, was here to-day. In the evening I saw the comet and swept. _14th._ ... I calculated 140 nebulæ to-day, which brought me up to the last discovered nebulæ, and, therefore, this work is finished. _15th._ I went up with Mrs. H. to Windsor to pay some bills and to buy several articles against my brother’s return. _16th._ ... my brothers returned about three in the afternoon.
