About various testimonials, from JH and others, for JF's application for a government pension.
Instructions for preparing liquid for the actinometer. Describes 'very strange' experiments on the spectrum as well as an 'unusual' cloud formation.
Pleased to hear JH's work is progressing. Disappointed with Dr. [John] Davy's meteorological observations at Malta. Comments on other scientific news, including recent eclipse, [Andrew] Crosse's controversial artificial crystals at Bristol B.A.A.S. meeting, JF's 1832 observations in Switzerland, and William Whewell's and William Buckland's books.
Requests papers relative to a preface to the catalogue of [N. L.] Lacaille's stars, so that the catalogue may be printed.
Believes JH expressed support for pension for surviving child of Thomas Henderson. Comments on this, stating his own view that she is already well provided for.
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.
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.
Mentions letter from William Whewell sending JF JH's interesting but puzzling meteorological results. Will communicate them to a Dr. [John?] Davy at Malta. Has been busy preparing lectures. Made a short tour in England last summer. G. B. Airy has been awarded the Lalande Medal.
Unable to assist JH's friend Major [Abraham] Cloete as JF was away from home. Comments on results of JH's table and JF's own papers and scientific occupations. B.A.A.S. would welcome JH's ideas for meteorological work. S. D. Poisson has published a new work on heat, in which he attacks J. B. Fourier.
Discusses methods of magnetic observation, JH's actinometric readings in the Cape, and the need for more physical observatories.
Sympathizes with JH's feelings of regret over actinometer readings. Has procured a new thermometer and carried out experiments toward correction of actinometers.
Thanks for medal of the Royal Society of Edinburgh.
Comments on JH's Treatise Astr. in the Cabinet Cyclopaedia, mentioning its continued publication, misstatements he wishes to correct, and his addition of A. de Gasparis's newly-discovered planet [Hygeia].
Comments on JF's article about glaciers and particularly on the solid, liquid, and other states of matter.
Expresses thanks for several of JF's writings and relief at JF's good health. Comments on JH's own writing.
Outlines theory behind and method for preparing thermographic paper, which allows observers to determine 'what share each ray of the spectrum bears in producing the observed total effects.'
Sets up approximate meeting time, depending on his family's timely departure to Antwerp, with JF at the R.S.L. apartments.
Calls JF's attention to an article in which an answer is attempted to JF's objection to 'the argument from probability of a physical connection between individuals of a double star.'
Describes difficulties in attempting to produce good meteorological register and establish national meteorological observatory.
Requests information about actinometers in JF's possession, and provides further information regarding their use.
