Returns the photographic drawings of W. H. Fox Talbot with many thanks. Fears for their permanence. Has produced similar pictures himself acting on bromide of silver with hydrocholoric acid. Has had trouble with his periscope lens.
Was gratified to receive his memoir and to find many of his doubts corrected by JH's experiments. Hoped to enclose some sulphuretted papers but the chemicals went astray in the post. Intends to follow JH's example and precipitate a glass.
Is grateful for the suggested emendations to his paper. Comments on the action of iodine on silver and its oxide. When can he expect publication of his paper? Has noted a peculiar property in the calorific rays when copying engravings. Encloses some Daguerreotype papers.
Arrived in England two days ago after a tedious voyage. Would like to visit JH. Off to Scotland next week. Called at the Colonial Office and had a friendly reception. G. T. Napier's dispatch has been received.
Is puzzled by JH's use of a word in his volume on astronomy; can he explain its meaning. Points out further misprints. Hopes JH will edit the works of his father [Sir William Herschel].
Would like permission to make a copy of one of the plates from JH's book on astronomy in order to print it in one of his own works intended for amateur astronomers.
Hears that JH is to be one of his parishioners. Outlines the local educational establishments. Should be grateful to know if JH would be subscribing towards their upkeep.
Sends two lithographs. Has seen the Archbishop and expects to launch his scheme with the approval of the leading politicians.
Is not well and is planning a holiday. Will be in the vicinity of Hawkhurst next Saturday and would like to visit JH.
Has just returned from Ely, where George Peacock is very happy and prosperous. Gives news of other scientific friends. Hawkhurst tithes have been peaceably settled.
Much indebted for his kind letter, but is unable to interfere in the affairs of Sir Francis Knowles as he has no contact with him. Encloses a list of instruments belonging to the late W. C. Holford and would be pleased if JH would show it to his astronomical friends.
Has just seen JH's communication in the P.M. regarding an improvement to a lamp. Points out that the late Charles Seward obtained a patent for this improvement some thirty years ago.
Sending a paper, compiled from his late father's notes, for an escapement for an astronomical clock. Would be pleased if JH would communicate it to the R.S.L.
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.
Sending the fourth volume of the magnetic observations; comments on these.
Has not heard of any results of JH's letter to D. F. J. Arago, but Georges Aimé has been appointed to direct an observatory in Algiers. Great interest at the Institute when JH's letter was read. Glad he did not waste a second letter to the Times.
Has received JH's letter with the sheet of curves laid down by [Charles] Riddell. Comments on these. Is honored by the notice JH has taken of his share in the magnetic project. Encloses note on the wet bulb [thermometer].
Has just received JH's letter of August as he has been traveling on the continent. Will see G. B. Airy tomorrow. Comments on Johann von Lamont's observatory at Munich. Discussed the Report of the Magnetic arrangements with Edward Sabine. Encloses letters. L. A. J. Quetelet would like support from the R.S.L. for additional observers in his observatory.
Regarding the publication of the magnetical and meteorological observations. Wonders if a letter from JH to the appropriate bodies would prove useful. Will give early consideration to the plan.
Took the chair at a meeting of the Committee for Physics at the R.S.L. Is to bring the matter before Council, who in turn will request the Master of Ordnance to publish the observations. Material from each observatory will require about half of a quarto volume.
