Sends some calculations relating to the construction of lenses.
Hopes that letter from Mr. Langton does not mean more trouble. Flood has made 'Complete Prisoners' of residents at Slough. Glad that JH bought good horse. Advice on JH's laundry. Caroline Herschel's finances. Concern for Georg Griesbach's health. Regards from Susan White.
Has received parcel from N. M. Rothschild. Hopes money for the Robert Molyneux clock will soon arrive. Encloses some items for him in Thomas Catton's parcel. Please accept Analytical Geometry. Hopes JL's two volumes on astronomy will be translated into English, and encloses copy of additions.
If either of the designs please him, he will be pleased to advise; otherwise explain in detail what he requires.
Some comments on sun spots based on William Herschel's ideas; considering a collection of William Herschel's writings but publishers not interested.
Regarding errors and discrepancies in the tables of F. W. Bessel. Difficulty of dispatching books to foreign members.
Gratified that JH appreciates the astronomical legacy that she left at Slough. Explains that she returned to Hanover because she felt that 'it would be in vain to struggle any longer against age and infirmity.'
