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.
PS's results on light and magnitude of stars agree with JH's results at the Cape. Comments on PS's research on light of planets.
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].
Asks WW to check the R.S.L. council book for 23 Nov. 1826 to inform JH as to who was present.
On the significance of the full moon and its influence on the weather.
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.
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 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.
Is translating Homer's Iliad and has heard a verse is missing from the standard versions. Can WM help?
Some comments on the variation of the eccentricity of the earth's orbit, and the geography of Mars.
