_Mar. 10th._—I was permitted to see him, but only for two or three minutes, for he is not allowed to speak. _Mar. 22nd._—He went for the first time into his library, but could only remain for a few moments. _April 7th._—I went to stay at Slough, my brother going by short stages to Bath, Mrs. H., my nephew, and Miss Baldwin with him. _May 9th._—My brother returned, nearly recovered, but with a violent cold and cough caught on the journey. _May 24th._—I went to Slough to be with my brother till the 31st. In fine nights observing; working in the daytime, and writing a paper on comets, filled up the time, though neither my brother nor myself were well. _June 7th._—Was the Montem, of course much company. _June 13th._—I dined at the Castle to meet Lady and Miss Banks, Mr. De Luc,[25] &c. * * * * * _July 1st._—Alexander arrived at Slough. _Mem._ We received very distressing accounts from our brother at Hanover. _July 21st_ till _26th_.—My brother was absent, and I was daily at work in the library. _Sept. 5th._—Alexander returned to Bath, leaving his brother far from well. The laborious exertions required for the polishing of the forty-foot mirror, besides the overlooking and directing the workmen out of doors, who were at work on the repairs of the apparatus, during the month of August, had again proved too much for him. _Oct. 4th._—I went to Slough; my brother, Mrs. H., my nephew, and his cousin, went to Brighton. My brother was absent about a week, during which time I worked as long as I could see in the library, and spent the evenings in booking observations, &c., and such works as could be done within doors. _Nov. 2nd._—My brother went to town, endeavouring to gain some information about my brother Dietrich, who, according to a message from a merchant in town, ought to have by this time been in England. _Nov. 6th._—A letter from Harwich arrived informing us that D. was waiting there for a passport. _Nov. 7th._—D. arrived at Slough, but was obliged to return for his trunk and to show himself at the alien office, and I did not see him till the evening of the 9th. _Dec. 19th._—Dietrich left Slough for lodgings in Pimlico, London. Came with Fr. Griesbach the day before Christmas Day, and returned to town the 26th. [Sidenote: 1809. _Extracts from Diary._]
