EW and daughter look forward to visiting Slough on Monday with Mr. Beckwith.

Needs the Ephemerides for 1769. Can he ask [James?] Graham[e] for any old pamphlets. Is expecting William Whewell and George Peacock and would be glad if JH can come as well.

Received JH's letter [29 Apr. 1821] with 'Memoirs of Astronomical Society' and observations of recent solar eclipse. Has not published eclipse calculations. Convinced that moon's diameter is accurately determined. Latitudes, longitudes for sites in Finland. 1820-22 observations from Ã…bo. Design of new Ã…bo observatory. New instruments from Munich.

Encloses list of books on Ireland as requested. Her brother is in London. Hopes that JH will visit them should he come to Ireland.

Encloses table of star declinations for 1815 and 1820, received from F. W. Bessel, who used different meridian circles for each year.

Orders lithograph of enclosed letter and tables for Astronomical Society.

Leaving for two weeks in Netherlands.

Regarding the construction of the model machine. Things appertaining to the Netherlands. Regarding his new chemical theory.

Has no errands for JH in Holland or Flanders. Asks for details on JH's and Charles Babbage's method of determining heights by barometrical observations. Hopes to use this to confirm TY's method by 'my formula deduced from refraction.'

Orders 30 copies of lithograph.

Sends circular of F. W. Bessel's 'Declinations.' Sent paper on 25 July for Royal Society of Edinburgh, similar to DB's paper outlined in previous issue [of Edinburgh Journal of Science]. Argues for continuity of color spectrum versus 'per saltum' transitions.

Thanks for the publications by FB that FB sent. JH has sent the copies to the persons FB designated. Discusses the 'enigmatical difference in the places of the stars as observed here & on the Continent.' Cannot explain this.

Leaving for Calais tomorrow. Unable to see Mr. Beckwith. Hopes [Susan] White arrived safely in Slough. Encloses Astronomical Society's notice of F. W. Bessel's determination of declinations of fixed stars.

Obliged to the Smiths for their condolences following the death of his daughter, Mrs Charlotte Lynn. She had nearly recovered from her long troubles with chest disorders and dangerous inflammations by taking extract of hemlock but was taken ill after drinking a glass of cold water following an exerting walk and never recovered. She has left twelve children between ages of sixteen years and six months. Two months ago he received and ignored a letter from Smith's sister, Mrs Lloyd, complaining of her husband's, Dr Lloyd, and Smith's confinement of her. Relieved that the King [George IV (1762-1830)] did not come via Carlisle on his way to or from Scotland. Thinks the current session of Parliament has gone on long enough and does not approve of the new principle of bringing every complaint, well or ill-founded, before it.

Received JH's letter from Calais. Visitors to Slough. Marquess of Londonderry committed suicide.

Thanks Smith for Hull Botanic Garden account, which he shall bind with [William] Roscoe's Liverpool and [William] Curtis' 1778 proposal for a subscription for a London botanic garden at Lambeth Marsh. His sister's health very precarious but he intends to tour Suffolk and Norfolk before end of summer. His daughter-in-law recovered a little from taking the waters at Barèges, [France], they intend to winter in Italy. Reports that Mr Grigby of Drinkston, Suffolk, was seized with a paralytic affection of his lower extremities whilst walking.
