FM has published, in translation, JH's article ['Weather and Weather Prophets' (1864)], already published in Good Words. JH was not aware that this was FM's intent, and JH warns him that some editors may be sensitive about such matters.

JH declines to negotiate further about FT's continuing occupancy of Herschel House.

Apologizes for not having answered earlier. JH's health has been 'indifferent.' Received 'Sur un Problème curieux de Magnetisme' yesterday. Discusses 'alleged free suspension of Mahomet's coffin.' Agrees with JP that 'establishment of a stable equilibrium under the influence of mere magnetic forces is impossible.' Elaborates on an experiment relating to the 'problem.' Lists the works by JP that he has.

Thanks for and comments on paper on luminous and obscure radiation, particularly on extra spectral rays, incandescence of platinum, and experiment using transcalescence of iodine.

Comments and will consider writing on article subjects proposed by Dr. [Norman?] McLeod. Requests Hebrew version of Genesis, chapter 1, with pronunciation and translation guides.

Reports on Edward Sabine's paper [R.S.P.T., 154, 227-] comparing magnetic disturbances at Kew and Nertschinsk. Makes suggestion regarding period of solar spots and other matters, but deems paper worthy of publication.

Wishes luck but expresses inability to help with new science journal [see JT's 1864-11-18].

Had hoped to attend ES's soiree, but has influenza. Praises ES's report on Mr. McClintock's magnetic observations at Port Barrow.

Gives reasons for and discusses technicalities of supporting pendulum experiments at astronomical and geodesical stations in Indian trigonometrical survey.

Comments on observations of sun and sunspots, especially R. C. Carrington's book on the subject.

Reports on G. B. Airy's analysis [R.S.P.T., 153,. 617-] of 177 magnetic storms.

Surprised that JT cannot obtain heat spots [see JT's 1864-11-14]. Describes glasses and lenses used.

Thanks for and comments on papers on scientific history and molecular physics, particularly on a magnetic experiment and on dynamical efficiency of coal relative to motion theory of light and heat. Comments on nature of heat, 'vis viva.' Deplores laxity with which physicists use and confuse terms 'force,' 'motion,' and 'energy.'

Raises with GA the likelihood of an error in a date of a transit of Mercury in a paper by F. A. Winnecke.

Sends WS William Herschel's chromatic observations of Beta Cygni. Completing 'Catalogue of Nebulae.' Works on translating Book IX of Iliad; fears he will not complete translation of Iliad.

Thanks PT for papers on energy. Discusses topics of the papers, including quaternions and the concept of heat equalling motion.

Cannot find the source of supposed Wilhelm Struve probability calculation; believes he has made a mistake. Regrets the error was not noticed in time to correct the seventh edition of Outlines Astr.

Compliments to the company.

Thanks WT for pageproofs of his work on analytical dynamics. Compliments work on Isaac Newton's view of nature of luminous ether. Gives own views on ether and motion theory of heat.

Comments on WS's publication on sidereal chromatics. Believes validity of doctrine of three primary colors proved.
