Grateful for letter from WJH's wife Emma. Maria Herschel's engagement to Henry Hardcastle. WJH's report on improvements in British administration of India is good news. News and whereabouts of Herschel family. JH paid WJH's annual taxes, but not dues to Amateur Photographic Association requested by J. Melhuish. Alexander Herschel leaves Tuesday for Pyrenees.
Confirms receipt of journals sent to JH by LQ. Calculations of probabilities for shots to hit targets.
Just read [?]'s article on [John?] Blackwood. JH's views on effectiveness of [Robert] Peel's act and on relative roles of government and Bank of England in nation's economy.
Responds to article by Mr. Yates in Daily News of the 18 May that misrepresented JH's views on standard units of measure.
Encloses published letter of 20 Dec. 1864 from JH to editors of Philosophical Magazine and Journal concerning Charles Babbage, who 'revived this miserable subject' of 1826 dispute between W. H. Wollaston and Humphry Davy regarding Babbage's candidacy for R.S.L. secretaryship.
Comments on GS's 1865-6-1.
Returns a paper on Indian meteorology, as he cannot devote time to it.
A letter of introduction on behalf of the Prescott family.
Comments on the revolution of the apsides of the earth's orbit and its effect on glacier theory; further comments on the earth pyramids of Botzen [see CL's 1865-1-31], and associated phenomena.
In response to comments in a paper by JC, JH writes to establish his priority with respect to the significance of the revolution of the apsides of the earth's orbit and the eccentricity of the earth's orbit in affecting temperatures on the earth. JH had spelled this out in an 1830 paper for the Transactions of the Geological Society, and repeated it in his Outlines Astr.
Writes to CL about JH's response to James Croll's paper. Includes an extract from JH's letter to James Croll [see JH's 1865-2-6].
Does not gainsay the influence of distribution of land and sea on the climate. The change of eccentricity is also a powerful influence. Comments on this. Sees that CL's book is published. Is it too late to send his drawings of the earth pyramids?
Thanks for his Elements [of Geology]. Evidence from the Arctic shells is decisive. Sends drawings by book post. Comments on these drawings. Near Arezzo are similar phenomena in a soft sandy limestone. Measured the tallest column at Riten and found it 74' 10" from stone cap to base.
Some comments on the variation of the eccentricity of the earth's orbit, and the geography of Mars.
Comments on why JH gave 239 degrees F as the temperature of space. Geological specimens may be given to the Geological Society or to the Jermyn Street Museum.
Comments on a table of U. J. J. Leverrier on the eccentricities of the earth's orbit.
Further comments on the theory of glacier formation, urging causes beyond merely astronomical ones.
Describes exactly the route JH took to get to the point where he made his drawings of the earth pyramids at Botzen.
Writes to ask for clarification of HL's views on the dispersion of light.
