Aru pigs present perplexing case, whether wild or domesticated.
Hugh Falconer’s death great loss to science.
His own health has been especially bad this last week.
Notifying him of a forthcoming meeting of the Lunar Committee of the B.A.A.S. Hopes he will attend.

Is glad MTM is going to experiment on Passiflora.
Is grieved to hear that John Scott has been inaccurate but cannot think he recorded, in his paper, experiments that he never made [see 4485].
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.
Having read JH's paper in Good Words on the weather he commenced a series of observations of the state of the sky during three days of each lunation. Will be pleased to continue sending his observations if JH is willing to accept them.
He has finished MEW’s work on hybrid willows [Die Bastardbefruchtung im Planzenreich (1865)] and sends his thanks. The extreme frequency of hybrid willows is new to CD, and he finds the explanation of their numbers in certain locations ingenious.
Comments on the criticism of Gärtner’s view of reversion
and the differences between MEW and Naudin.
CD now has doubts regarding his own view that hybrids are sterile from not being perfectly accommodated to their conditions of life.
Sending his paper on the causes of change of climate, and would be glad of JH's comments and opinion on its worth.
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.
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].
