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.
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.
