Regrets having missed JH. Has observed the seven satellites of Saturn and the fifth star of the Trapezium. Wishes to observe some of the objects observed by Wilhelm Struve.

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.
Thanks for the publications sent; lists materials JH is sending JL. Asks about quality of Josef Fraunhofer's large telescopes. JH read part of JL's letter of 2 Jan. 1822 at Astronomical Society meeting. Discusses proper motion of sun, JL's work on latitude of the pole star, observatory clocks, micrometers, and the Cambridge Observatory.
Informs FA of his election as an associate of the Astronomical Society. Includes message for Alexis Bouvard.
Sends first volume of the 'Transactions' of the Astronomical Society to the Philosophical Society of New York.
Discusses the pros and cons of GE's proposal that [J. C.?] Schenck, a Swiss maker of optical instruments, set up a business in London. JH is not sure that JH ascended Mt. Rosa, but is certain of JH's barometric reading. Interested in GE's method of estimating air temperature.
Lays out various practical rules for the determination of the radii of a double acromatic object glass.
Urges JH to come to Brighton and then to return with him to Cambridge; stresses that both he and Richard Jones are anxious to talk with JH.
Discusses regions of the Alps and sends sketch of Monte Rosa. Informs JH of a brilliant student, G. B. Airy, who is constructing a calculating machine. Condolences on the death of William Herschel.
Thanks WW for drawing of Monte Rosa. Comments on a recent political election.
Gives advice on WW's planned trip to Europe. Asks WW to contact various scientists there on JH's behalf.
Encloses list of books on Ireland as requested. Her brother is in London. Hopes that JH will visit them should he come to Ireland.
Has had a letter from [J. C.?] Schenk of which he encloses a copy as it was possibly intended for JH. Will be pleased to hear about his expedition to Monta Rosa. Has found new method of estimating the mean temperature of the air. Was too late to see Vesuvius in eruption. Let him know if he wishes to say anything to Schenk.
Would like very much to see JH as soon as possible. Has an instrument of [J. C.?] Schenk to show him. There is one on the way to him now from Paris.
Cannot leave the instrument with Edward Troughton later than Saturday. Perhaps Troughton had better leave the instrument in the box until GE calls.
[J. C.?] Schenk has reason to be grateful to JH for all his assistance. Schenck's friends can now judge whether it will be expedient to bring Schenk to London to set up in business. Awaits anxiously the verdict of Edward Troughton.
His health has been poor and is still not well. Outlines his surveys for the site of the Observatory, difficulties of storing instruments, lack of finance. Gives details of the observations carried out so far. First assistant is leaving and has appointed a R.C. priest. Remember him to his friends.
The comet is not visible. All is ready for its observation. How is the Cambridge observatory progressing? Comet still not visible. Wishes he had a good telescope.
Has received letters from the Admiralty, which have allayed all his previous distress. Is to receive two telescopes. Weather has been unsuitable for observations.
Has delayed answering his letters owing to the health of his father. Grieves to hear of the health of FF. Board of Longitude are fully behind FF. Does not agree with some of FF's proposals.
