Returns with grateful thanks the example of photographs recently sent him. They open up a new field of curious processes. Will not have much time this summer for photographic experiments as he is carrying out a series of investigations into the air of mines. Has been experimenting with the cyanurets.
Sends back the slips. Does not approve of the phrase transcendentalists. Regrets that the subject forms a review; it is worth a treatise. Is working hard on his book. Would like to raise some rose trees for Lady Herschel.
Sends check for £100 being payment for JH's article on William Whewell's book. Will always be pleased to receive suggestions.
Comments on a paper on the calotype by W. H. F. Talbot, adding some experiences of his own on the subject.
Will be receiving the official news soon that JH has been nominated Knight Commander of the Order of Dannebrogg. New magnetic observatory to replace the old one. Is grateful for JH's excellent song about the telescope.
Expresses his great appreciation for informing JH of the honor being conferred by making JH a Knight Commander of the ancient and venerable order of Danneborg.
Sends JH sample of chemicals and paper to make calotype himself.
Is thrilled about 4 aides to help with meteorological and magnetic observations. Points out that number of stations participating in horary observations increased to 22. Lists them. Hopes to go to Plymouth [B.A.A.S. meeting].
Reports on Francis Baily's accident and his progress. JH's 'stars' were brought to the R.A.S. and examined by Baily. Mrs. G. B. Airy's health improving. Notes William Whewell's planned marriage.
Thanks RS for the news of Francis Baily; requests an update on his condition. Criticizes 'reduced map' prepared by [James] Basire. Has drawn up a catalogue to go with his paper, as RS requested, arranged in regions. Praises William Whewell's choice of a bride.
Updates Francis Baily's medical condition, noting that it is more serious than RS had thought. Thinks [James] Basire missed JH's meaning. Suggests how to improve the engraving, perhaps using pewter. Explains that he wants the catalogue to serve the needs of expeditions.
Regarding his recent experiments with light in crystals of alum etc.
Is sending him his chart of the stars.
JH's paper was read last evening and was well received. Astronomical Council has decided to print it immediately. Would like his opinion on the printing of various parts. Has paid John Arrowsmith's bill.
Regarding the printing of the star map. Is pleased to hear that the FBs are coming to spend a few days at Hawkhurst.
Received WB's report on barometer observations. Admires perfect finish of work.
