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.

Would like JH's account of his own method of fixing a photograph as noted in his memoir. Singular phenomenon of the Daguerreotype. Hopes to produce a photographic paper to equal the silver plate before the month has expired. Will let him know when his process is complete.
Is grateful for the handsome manner in which JH has acknowledged RH's work. Would be willing to prepare a memoir for the R.S.L. Does Louis Daguerre's patent affect RH's manufacture of photographic papers? Has not studied the bromnets so far, but has studied the effects of bromine on plates. Comments on his results.
Apologizes for his long silence. Outlines recent events at the Cape concerning Andries Stockenström, who has been replaced by J. Hare, and Major C. C. Michell, who has resigned. J. R. Innes has been all over the Colony and will shortly be coming to England. F. M. Eardley-Wilmot has dined with the Napiers.
Sends JH a pamphlet about meteorological observations in India.
Waxes lyrical about nature, and comments on a new 'positive' paper JH has sent. Refers to JH's move to Hawkhurst.
Asks JH's advice in establishing new astronomical, meteorological, and magnetic observatory at Harvard University. Describes instruments already owned and those ordered from Europe.
Hopes [Humphrey] Lloyd will reconsider V.F. Magnetometer based on JH's remarks. Discusses Canadian observatories. States who will perform U. S. magnetic survey. Discusses micrometer use.
Discusses Charles Riddell's desire to serve at a North American observatory and the expenses involved.
Suggests a book of expenses be kept at the R.S.L.
Discusses plans for a U.S. magnetic observatory and of [Karl] Kreil's paper about predicting earthquakes. Discusses the affairs of other observatories.
Has received materials from [A. D.] Bache indicating that the U.S. government has proposed to establish 5 magnetic observatories.
Writes of a magnetic survey of a portion of India and the inaccuracy of the equipment used in magnetic observations at sea.
Discusses glass manufacturing.
Describes additional measurement of annual parallax.
Should think that the R.A.S. would be pleased to receive the 5-ft. telescope. Regarding the printing of Thomas Maclear's paper. H. C. Schumacher has sent a paper by Wilhelm Olbers on the constellations.
Anthony Oliphant has died. The plan to establish a system of meteorological observations at the Cape Colony and in Caffreland has failed.
Has received [Temple?] Cheval[l]ier's paper and JH's letter informing him of his valuable gift. G. B. Airy is anxious to have Thomas Maclear's paper printed in the Memoirs as soon as possible without waiting for the government.
When the case containing the stand of the telescope was opened it was found to contain a number of books. Were these intended for the R.A.S. or should they be returned to JH?
