Draws JH's attention to an article in the most recent Philosophical Magazine.
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].
Sends copy of JT's '3rd Memoir,' along with specimens of liquid mercury ethyl and mercury methyl from discoverers Edward Frankland and B. F. Duppa.
Asks WW to check the R.S.L. council book for 23 Nov. 1826 to inform JH as to who was present.
Was pleased to receive JH's letter requesting him to communicate the subject to the Society. Has been busy preparing the Annual Report so has not had time to follow up Mr. Traye's papers.
R.S.L. approves of CP's optical work, believing it will be helpful at observatories abroad. CP comments on Alexander Herschel's prism experiments.
Regarding the editions in which he cited JH's paper. Further comments on James Croll's paper, and on the effects of glacial and astronomical events. Is the quantity of heat radiated by the sun in the course of the year always the same? Thanks for the drawings of the Botzen columns.
On the significance of the full moon and its influence on the weather.
At JH's request, WW sends JH a list of members present at the 'irregular' council meeting on 23 Nov. 1826, together with the business recorded in the minutes, which does not include any mention of the matter of the secretaryship of the R.S.L.
Attempts further clarification of the matter discussed in JH's 1864-12-20 to the P.M. Reiterates JH's recollection of a conversation between W. H. Wollaston and Humphry Davy, which JH had described in a letter [see JH's 1826-11-25 to Francis Baily] and which JH refers to in his letter of resignation to Davies Gilbert [see JH's 1827-6-27], which latter letter JH quotes.
Thanks for his letter concerning his own paper on the changes in climate. Points out parts where JH seems to have been mistaken in his views as expressed.
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?
By all means retain the specimens and send them to Lyell or anyone else as he sees fit.
Has ordered that a copy of his new 6th edition of the Elements [of Geology] should be sent to JH. He wants the drawings of the earth pillars for the 10th edition of his Principles dealing with the effect of rain. JH's drawing made a great impression on him.
Regarding the assaying at the Mint. Hopes JH will use his influence to assist W. H. Barton's son.
Thanks for his letter and comments. Is always pleased to have any omission pointed out. Comments on his theories of the changing of the climates.
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.
A letter from the Secretary of R. S. L. asking JH to review several papers. [Appended is a copy of JH's review in draft form.]
Impressed by JH's [1824] drawings of earth-pillars in Botzen. Plans to visit them this year. Causes of earth-pillars. Speculates on climate changes on planet Mars.
