I feel very great gratification at recollecting that some twenty years ago I had the pleasure of being present when you were conversing at Slough with my dear brother, for it encourages me to address you now as an old friend, and I might almost say my only one, for death has not spared me one of those valuable men of the last century in whose society I had an opportunity of spending many happy hours, when they came to pass an astronomical night at Bath, Datchet, Clay Hall, and Slough. And I should now in the absence of my nephew (who would in my name have properly answered your kind letter for me) been much at a loss how to reply to yours of March 17. But I hope, dear Sir, you will have the goodness to return my sincere thanks to the Council of the Society for voting me a complete copy of their Memoirs. But, considering my advanced age and declining health, I think it best not to have them sent over to me, for it would cause me much uneasiness to leave them in the hands of those who could neither read nor understand them. I suppose my nephew must have himself a complete copy of the Memoirs; but, if not, I beg you will give them to him, along with my love, as a keepsake from his affectionate and grateful aunt, the first opportunity you have to see him on his return. Your kind information of the work with which you are at present engaged, touches a string which it has caused me no small trouble to silence; for whenever my thoughts return to those two or three years of which every moment that could be spared from other immediate astronomical business was, by my brother’s desire, allotted for comparing each star of the British Catalogue with their observations in that _incorrect edition_ of 1725, I feel always sorry that want of time, and, perhaps, want of ability too, must have been the cause of leaving many incorrections unnoticed. The work, however, was solely intended for the use of my brother, who valued Flamsteed as an observer too much to have made use of any other but the British Catalogue for determining the places of his newly-discovered objects. N.B. We ought to remember that till the year 1790 and 1800, when Wollaston’s and Bode’s Catalogues appeared, we had no other to go by, for those of Piazzi and several other excellent observers were then not generally known. But, dear Sir, I ought to take leave of this to me interesting subject; for finding, about eight years since, that, on account of the failure of my eyes and wretched health in general, I should be unable to make further use of Flamsteed’s works, I gave the three volumes, along with the Atlas, Catalogue of Omitted Stars, &c., to the Observatory of Göttingen, all marked throughout with what corrections I knew of at that time; thinking they might be of use to the observer there, and relieve me besides from the fear of leaving them where they could not be appreciated, or an attempt be made to comment on them, and perhaps have made bad worse.
