_July 6th._—In the evening they both arrived at Slough. _July 10th._—Alexander joined us from Bath.... The same day my eldest brother went to the visitation of the Observatory at Greenwich, and my brother D. accompanied him. They returned on the 12th. _July 13th._—We went all to the Terrace, and took our tea with Mrs. Bremeyer and Mr. Beckedorff at the Castle. _July 23rd._—Dietrich took leave of his friends at Cumberland Lodge. Alex. and I accompanied him. In Windsor I went shopping to buy presents for my Hanoverian relations. _July 24th._—D. left us. My eldest brother and Mrs. H. accompanied him to London. * * * * * * * * * * _August 1st._—I left Upton for Slough. My brother went with Mrs. H. and Miss B. on an excursion. My nephew went to spend the holidays at Newbury, at the Miss Whites. One man and a woman were left with me to take care of the house. I distracted my thoughts by undertaking an amazing deal of work; among the rest, I made catalogues of all books and MSS. my brother’s library contained, and arranged them, to the best of my knowledge, according to what the confined room would allow. [Sidenote: 1806-1807. _Extracts from Diary._] _September 8th._—My brother and family returned, and I went with my works to Upton. Dr. and Miss Wilson were at Slough from September 22nd to September 30th. _Mem._—During September, and the early part of October, many days were spent at Slough in assisting my brother when the 40-foot mirror was re-polishing. _December 28th._—I went to see Mrs. Bremeyer, but found she had died ten hours before my arrival at the Castle. _January 15th._—My brother went to Bath to see his brother and Sir Wm. Watson. _January 24th_, _5th_, and _6th_.—I spent with my friends at Windsor. My brother returned with a violent cough, added to a nervous headache which it had been hoped would, by change of air, have been removed. My brother brought the place of a comet announced in the papers with him. I had also heard of it at the Castle, and saw it on the 27th at Upton. Next day I had my sweeper carried to Slough, but the nights of the 28th, 29th, and 30th were not clear enough, and I could not find it again till the 31st, when my brother began his observations on it.... _May 2nd._—I left Upton for Slough, to work with my brother. Mrs. H. being in town till _June 18th._—Spent the day at Slough, Mr. and Mrs. Watt being there on a visit, and a large party to dinner. _Aug. 13th._—I went with Mrs. H. and my nephew to pay a visit to our friends at Cumberland Lodge. My brother, again finding it necessary to recruit his strength by absenting himself for a few days from his work-rooms, had left Slough for Tunbridge Wells just the day before, and at our return we found the Duke of Kent, with the Dukes of Orleans, &c., waiting for us, and my nephew [ætat. 15] and myself showed them Jupiter, the Moon, &c., in the seven-foot.
