Comments extensively on the orbits of recent comets.

Thanks for his letter. Will communicate to P. G. le D. Pontecoulant what JH has to say about him. It was certainly unwelcome that JH should omit JL's name when referring to the lunar theory.

Has sent the letter and diploma to the King of Denmark. Regarding the printing of Thomas Maclear's paper on N. L. Lacaille. H. C. Schumacher has seen a third comet.

Encloses some more calculations of height by means of the barometric mean temperature. Comments on these. Staying at Ackworth until April.

Acknowledges letter requesting land for the Magnetic Observatory. Has a portion of land available in the S.E. corner of the grounds, but it will be necessary to obtain the permission of Rear Admiral George Elliot.

Reports on instruments being sent to Hamburg and to Egyptian observatories. Encloses portion of [K.] Kriel's letter to [A. T.] Kupffer. Reports on [Charles] Riddell's securing a site for a meteorological observatory.

Progress in construction of observatory. Completion expected in May. Poor weather hampers actinometer observations.

Obliged for his kind note and also for forwarding the paper to the R.S.L. Would like to belong to the R.S.L. and would be pleased if JH would sign a certificate for him.

Sent an extract of JH's letter to P. G. le D. Pontecoulant. Now gives an extract from Pontecoulant's reply. Is sorry they are not to see JH at S. J. A. Compton's (2nd Marquis of Northampton) tonight.

Sends two lithographs. Has seen the Archbishop and expects to launch his scheme with the approval of the leading politicians.

Erebus and Terror have arrived in Simon's Bay. Discussed Magnetic Observatory with J. C. Ross, Captain Croper, and F. E. Wilmot, and wrote government requesting funds. Obelisk has not yet reached the Cape. Small pox rages in Cape Town.

Describes the process of preparing photogenic paper, taking drawings, and fixing them.

Indicates travel plans, including a visit to FB, with a side trip for business to Slough. JH comments on some astronomical observations he has received.

Thanks for 'small, but intense' volume sent.

Thanks RS for all the trouble he took with the problem of his portrait. Is anxious to see the specimens of the engraved nebulae of which RS spoke, but confesses little hope in photographic 'reverses' of pencil drawings. Has installed his family at Collingwood.

JH is preparing to leave residence at Slough, and all notes on William Herschel's life are packed away. Refers [?] to published biographies, but adds some corrections to those.

Was not certain how to reply to his last obliging letter. Has resolved to write to Professor [J. P.?] Müller. Thought it right to inform JH of his plans.

Hopes that his paper does not anticipate any of RH's work; will share with the R.S.L. any of RH's results. Laments that he is unable to fix the spectral colors on photographic paper. Asks if RH has studied the bromines.

Packing up the 7-ft. and 10-ft. reflecting telescopes for their trip to Collingwood in Hawkhurst in Kent, JH's new home.

About the choices to be made in moving furniture from Slough to Collingwood; problems about the election of a minister at Eton.
