Summary

Will try to call tomorrow. What HF tells him about horses makes him eager to come.

Summary

Extreme interest in MS of HF’s paper on the American fossil elephant [Nat. Hist. Rev. n.s. 3 (1863): 43–114].

Pleased HF does not believe in immutable species. Significance of proboscidean group verging towards extinction. Comments on natural selection preserving type despite variability. Natural selection solves problem of how every part of each creature has become adapted.

Summary

Explains that he returned the MS - part of a paper on fossil and living species of elephant (Falconer 1863) - to Falconer’s house in Park Crescent the previous Thursday.

Summary

Comments on HF’s paper on Plagiaulax from the Purbeck beds. Paper "dreadfully severe" on Owen.

"I am worse than ever in bearing any excitement."

Glad HF attacked Australian Mastodon. Never did believe in him.

Mentions Primula paper [Collected papers 2: 45–63].

Summary

Has HF met with any cases of what gardeners call "sports" and what CD will call "bud-variations"?

Summary

Wanted to talk with CD about the astonishing new Pliocene fossil discoveries in North America reported by Leidy. One horse fossil’s dentition, if it could be believed, would be of great interest to CD’s views.

Summary

Encloses MS ["On the American fossil elephant", Nat. Hist. Rev. (1863): 43–114]. Shows persistence of specific characters through glacial period.

Eocene monkeys mistakenly described as pigs.

Summary

Inquires whether previous letter was received by CD.

Summary

Although their views differ, HF is glad they can discuss those differences without offending.

Summary

Sends paper on affinities of Plagiaulax ["On Plagiaulax from the Purbeck beds", Q. J. Geol. Soc. Lond. 18 (1862): 348–69].
