Writes to urge GA to avail himself of the opportunity of working with Basil Hall in swinging the pendulum at Greenwich; concludes with a note for William Whewell about JH's view of the 'extremely irregular' figure of the earth.
Comments on GA's observing in Cornwall, and on the geodetic calculations made by GA in a paper read by JH.
Comments on a paper on achromatic eyeglasses submitted by GA to the R.S.L.; also on a paper of William Whewell's on the operation of a pendulum.
A letter of introduction for a Mr. Thomson, who intends to go to South America and establish schools, and wishes to talk to GA about university education.
Thanks for valuable communication, which will be laid before the Board of Longitude. Has completed own paper for the Astronomical Society. J. F. Encke has sent more copies of the proof-map. Ernesto Capocci's observations of the comet similar to his own. Has been unable to use Charles Tully's or John Ramage's telescopes yet owing to clouds.
Remarks on FB's address on astronomy [fragment only].
Learned of vacancy in Lucasian Professorship at Cambridge. Wrote to [T. W.] Hornbuckle explaining why JH declines. Asks JW's support for Charles Babbage.
Dr. [William] French withdrew candidacy for Lucasian Professorship. JH again attests to Charles Babbage's qualifications for that position, which includes seat on Board of Longitude.
Invites HK to dinner Saturday to meet James South and Alexis Bouvard.
Asks questions about the prospectus [see JE's 1826-3-2] prepared by the Berlin Royal Academy for a map of the heavens. Asks JE to send JH a copy of [K. L.] Harding's star atlas.
Reports on interest at the Astronomical Society, especially of [Thomas J.] Hussey, in the plan of the Berlin Academy for a new star chart. JH cannot participate due to JH's commitment to re-examine his father's nebulae, which requires that JH reside far from London.
Encloses an outline of JH's paper on iron [? 'On the Separation of Iron from Other Metals,' RSPT (1821), 293-9].
[Responding to WT's 1826-2-7], JH thanks WT for materials sent, makes suggestions regarding WT's upcoming trip to Geneva, and asks WT to deliver a book to [Alfred] Gautier.
[Responding to WT's 1826-3-24], JH concurs with P. S. Laplace's view about the advantage of astronomical observation from high elevations, e.g., from mountains. Comments on telescope prices, a paper by WT, Florence, and JH's plan to visit the Continent.
Thanks WT for bringing to JH Josef Fraunhofer's publications and Franz Gruithuisen's plates. Recounts JH's geologizing in France and JH's efforts to measure solar radiation.
Asks WW to watch over the printing of JH's 'Light' for the Encyclopaedia Metropolitana. Describes that work as not especially original and as free of historical information. Discusses JH's trip to Calais.
Declines to become a candidate for the Lucasian professorship. Explains his reasons. Has written in support of Charles Babbage. Thanks WW for seeing JH's 'Light' through the press. Describes JH's travels on the continent, including his 'geologising.'
Thanks for ME's letter; JH hopes to see her in Ireland in summer.
Has read his paper on vaporization with much interest and can see no objections to its arguments. Comments on some of the details.
