B.A.A.S. and Royal Society of Edinburgh have been approached to apply to the government for finance to send an observer and reflector to the Cape Observatory. Does JH think this advisable, with his knowledge of conditions at the Cape?
Was pleased by JH's favorable opinion of his paper on the Vivarais. Finds JH's arguments concerning [John] Michell's theory of probabilities unconvincing. Will soon write a paper on the problems.
Regrets he has not been able to find anyone suitable for the chair of chemistry and natural philosophy at Sydney University.
Thanks for JH's article on meteorology from the Encyclopaedia Britannica. Has been investigating climatology lately. His own health has not been good. Sends some of his own reprints that may be of interest.
Article on glaciers is from the Encyclopaedia Britannica and was restricted because of space. Mistakes by John Tyndall and others have arisen because his own Letters on Glaciers has been overlooked. William Whewell is to be married.
Has he read John Tyndall's paper on the plasticity of ice and the theory of glaciers? Indebted to Michael Faraday for some excellent observations and the term 'Regulation.'
Has requested his publishers to send JH his recent volume on glaciers. Thanks for JH's Physical Geography.
Is a candidate for the position of Principal at St. Andrews United College in succession to David Brewster, who has moved to Edinburgh. Would be pleased to receive a testimonial from JH. Has already received one from Brewster.
Sends thanks and congratulations for paper verifying electric origins of all magnetism. Will give JF an actinometer with complete instructions. Includes some instructions for obtaining and using it. Sends regards to Mario Gemellaro, should JF go to Catania.
Suggests that JF use his instruments to compare the force of solar radiation at high and low elevations. Delineates possible methods for this experimentation, and lists results of similar experiments. Includes further information on the actinometer.
Gives JF permission to use JH's letter to JF's brother in any way JF sees fit to obtain the Chair of Natural Philosophy (at Edinburgh), but still does not wish directly to promote JF's selection. Briefly discusses results of JF's experiments with the actinometer.
Is drawing up a new actinometer and comments on JF's ideas about it. Encloses a letter to JF's brother.
Congratulates JF on obtaining, after some difficulty, the Chair of Natural Philosophy at Edinburgh. Accepts offer to discuss meteorology with JF's relation Leslie Melville[?], and hopes to mention his actinometer.
Offers JF advice about the telescope mirror [?] and looks forward to seeing JF on his way to France.
Wishes JF well in [Edinburgh] and leaves addresses where JH may be reached [at the Cape].
Discusses reduction of barometric observations. Praises the Cape's climate.
Discusses methods of magnetic observation, JH's actinometric readings in the Cape, and the need for more physical observatories.
Thanks JF for papers and requests copies of those JH has borrowed; comments on JH's observations on solar heat, light, and lines in spectra.
Discusses prospects for meteorological committee of B.A.A.S., on which they both will serve. Lacks time for it. Does not need hourly observations made by Committee of Physico-Mathematical Society of Edinburgh.
Writes 'in haste' to thank JF for a pair of papers. Comments on Louis Daguerre's pictures in Paris.
