Summary

Thanks for letter and "valuable" extracts.

If S. American Carabi differ more from other species than do those from other distant locations (e.g., Siberia, Europe, etc.), CD agrees that difference would be too great to have occurred in the recent glacial age; CD also rejects independent origin. Plants seem to migrate more readily than animals. HWB should not underrate length of glacial period; CD also believes they will be driven to an older glacial period.

Sorry about news of British Museum – hopeless to contend against anyone supported by Owen.

CD dearly wishes HWB could find a situation in which he could give time to science.

Summary

Discusses insects of south temperate S. America and New Zealand, especially with respect to the distribution and origin of Chilean Carabi, and has sent for a German monograph to learn about the eleven species he has found.

He refers to Chilean poverty in butterflies; scanty New Zealand insect fauna.

An analysis of south temperate insects is desirable, but the small English collections make him afraid to undertake it.

Summary

Sends CD West Ireland soundings.

More detail on his review "a la Lindley" [see 3797].

Bates’s paper ["Contributions to an insect fauna of the Amazon valley", Trans. Linn. Soc. Lond. 23 (1862): 495–566] is capital.

Andrew Murray’s article plays into CD’s hands through sheer ignorance.

JDH is on Royal Society Council.

Has no recollection of applying natural selection to Polynesians. None but a German would dig out such a passage if it exists [see 3812].

Has caused Tyndall to modify his pseudo-geology.

Has not seen Duke of Argyll’s review [Edinburgh Rev. 116 (1862): 378–97]. [The Duke] did not understand Orchids the least little bit, nor the Origin, when JDH saw him.
