* * * * * _June 10th._—My brother, being about this time engaged with re-polishing the forty-foot mirror, it required some time to restore order in his rooms before any strangers could be shown into them, and I again was assisting him to prepare for the reception of the Emperor Alexander and the Duchess of Oldenburg, &c., as they were at Windsor for Ascot Races. But we might have saved ourselves the trouble, for they were sufficiently harassed with public sights and festivities. * * * * * _Sept. 13th._—During the time I was with my brother I saw among the visitors, &c., General P., who informed us of General Komarzewsky’s death, and on my expressing a hope it might not be true, le Général said he had buried him himself at Paris, and had erected to him a little monument as long as seven years ago. [Sidenote: 1815-16. _Extracts from Diary._] _Sept. 30th._—I came to my home again, but under the greatest concern at being obliged to leave my brother without my little help. But I have since been with him every morning till he told me he should leave off. His strength is now, and has for the last two or three years not been equal to the labour required for polishing forty-foot mirrors. And it was only by little excursions and absence from his workrooms, he for some time recovered from the effects of over-exertion. _Nov. 15th._—I went to work with my brother, which chiefly consisted of calculations and constructing new tables for the Georgian satellites, &c., &c. _Nov. 29th._-Mrs. H. returned, and I continued calculating and copying at home. * * * * * _Aug. 11th._—Alexander left Slough, my eldest brother with him, going on to Dawlish to recruit his strength again. His declining health had a sad effect on Alexander’s spirits, and I was in continual fear of the consequences; for nothing but the thoughts of the yearly meeting had till now kept up his spirits. From what is yet to follow, it will be seen that our next meeting was not only the last, but a very distressing one. _Sept. 11th._—I went to be with my brother, and remained with him till the 12th of October. The first fortnight of my being with him he was not able to do anything which required strength. * * * * * * * * * * _Jan. 2nd._—I was obliged to attend at Slough by eight o’clock, to be present when the Archdukes John and Louis of Austria visited my brother and his instruments. _Jan. 9th._—My nephew received a diploma of being Member of the University of Göttingen. The packet brought very satisfactory letters from our brother at Hanover.
