Recommendations on how best to make tidal observations.
Thanks for sending his "magnificent book" [Discoveries in Australia (1846)].
Asks JLS to visit Down on "Saturday the 16th" and Sunday. He has also invited Forbes, Falconer, Hooker and Waterhouse. [See 1036.]
No summary available.
Explains combined British and foreign postage rate applied to JH's letter, which has been forwarded to France. [JH annotation on verso about actinometer.]
Sends extracts of a letter from H. C. Schumacher. Does not agree with Schumacher regarding F. W. Bessel's 'specific attraction.'
Has been investigating the Cavendish experiments recently repeated by Francis Baily. Thinks G. B. Airy has neglected the resistance of the air in his mathematical theory. Would like to send an abstract of his investigations so that JH can judge their merits.
Recounts discussion in R.A.S. council regarding how the Society's medal should be awarded in response to the discovery of Neptune. U. J. J. Leverrier led J. C. Adams in the voting, but did not receive enough votes.
Needs someone to translate German/Latin letters; about James Ross's polar expedition.
Will do what he can for J. C. Gerhardt. Appears to be unfair regarding Isaac Newton and G. W. Leibniz. Is working on a list of writings in arithmetic.
Is grateful for his letter on the Cavendish experiment. Gives outline of his own theories regarding certain aspects of the Cavendish experiments, and would like his opinion on these before they are incorporated into a paper.
Sends a note along with a work on vision.
Congratulations on how the deliberations concerning awarding the R.A.S. medal came off 'well & quietly.' Recommends how JH's notice on F. W. Bessel should be distributed.
Has seen the papers, which consist of some 30 pages, the longest being in the Commercium Epistolicum. Knows someone who would copy them accurately and at a reasonable price.
Comments on letter by Bernhard Studer ["Remarks on the geological relations of the gneiss of the Alps", Edinburgh New Philos. J. 42 (1846–7): 186] and on article by DS ["On slaty cleavage", J. Geol. Soc. Lond. 3 (1847): 74–105]. Discusses geological cleavage and foliation.
Quotes from South America [p. 167] on the foliation of metamorphic rocks.
Much interested in BS’s letter on gneiss ["Remarks on the geological relations of the gneiss of the Alps", Edinburgh New Philos. J. 42 (1847): 186–7].
Sends copy of South America.
Has shown that lamination of metamorphic schists closely allied with cleavage.
Acknowledges receipt of [The naturalist’s pocket] almanack edited by LJ. Suggests some improvements.
Sending a revised copy of his own memoir on F. W. Bessel. Council of the R.A.S. have not awarded a medal this year.
Sends his manuscripts. Discusses some of Michael Faraday's experiments, in particular his theory on the non-magnetism of blood. Has sent Faraday a paper on the action of voltaic currents.
Asks CL to address a letter to Charles Maclaren.
Discusses recent publication by David Milne on erratic boulders [Edinburgh New Philos. J. 42 (1847): 154–172].
Views of Bernhard Studer on foliation of gneiss in the Alps. Asks CL to tell Leonard Horner of Studer’s views.
