A friend has requested JH to ask JS whether JS has a large Cauchoix objective lens that he would be willing to sell. JH has dismantled his 20-ft. telescope for voyage to Cape Town.

Let him know when the next Levee is.
Is unable to get a firm answer from James South as to the availability of a large telescope object glass that James South owns.
Sent to CH JH's fifth catalog of double stars. JH will send to CH his new nebulae observations very soon.
Assures JS that the person interested in purchasing JS's lens has worthy intentions for it, i.e., its use in a public institution. Regrets that JS distrusted JH's good intentions.
Reports observations with WS's equatorial during Bedford visit. Packs instruments for voyage. Pleased that Thomas Maclear will take post of Astronomer Royal at the Cape Observatory.
Received £500 from J. C. Spencer (Lord Althorp) for reduction under the direction of G. B. Airy of earlier planetary observations. Althorp conferred with Lord Grey. Conjectures possible need of a larger grant.
Has received a note from J. C. Spencer (Lord Althorp) stating that a grant of £500 is available for them [R.A.S.?]. He has acknowledged it.
JH has written to James South again [see JH's 1833-7-8] but has received no answer; is suggesting that it may well be that [R. A.] Cauchoix, the French optician, can supply object glasses as good as those James South has.
[Extract from a letter of this date to James South:] Tells FA that FA's magnetic experiments have been successfully repeated in England by Peter Barlow, Samuel Christie, Charles Babbage, and JH. Gives details. Publication in process.
Encourages GA to consider favorably the offer of Hugh Percy [Duke of Northumberland] of donating a telescope to Cambridge Observatory.
Arranges to meet TH, probably at Slough, and also to get a barometer from TH.
Offers a paper ['Note sur la manière d'agir de l'acide nitrique sur le fer,' Annales de chimie, 54 (1833), 87-94] for publication in Annales de chimie. Informs FA how to correspond with JH while JH is at the Cape.
Invites CW to Slough to demonstrate CW's 'elegant experiments on light & sound.' Will need time to get JH's electric machine in order. Asks for copy of CW's paper on Jew's harp.
A note along with letters from R. A. Cauchoix, the telescope maker, and [J. C. Spencer,] Lord Althorp, about the B.A.A.S.; JH is trying to clean up observation reports before leaving for the Cape.
Further about the telescope to be donated by Hugh Percy [see JH's 1833-8-15], along with a promise that JH will write to R. A. Cauchoix about the telescope.
Asks for reply to specific questions regarding telescope quality and price [see JH's 1833-8-29].
Excuses himself from a dining engagement; JH is too busy preparing for a voyage.
Informs JH that WS has sent fifth catalogue of double stars by [H. C.] Schumacher. Provides African address. Departure by 20 October on 'Mt. Stewart Elphinston—a superb India ship.' Notifies of [Thomas] Maclear's succeeding [Thomas] Henderson at Cape observatory.
Describes sighting while at Slough a remarkably bright occurrence of the aurora borealis.
