Summary

The antlers of 800 deer of the glacial period have been found in a cave. They show great variety of form, but gradation from one to the other can be traced when all are laid out. Suggests CD study changes that have taken place in the species since glacial period.

Has ordered the wicked book [Origin] CD has been so long a-hatching.

Summary

Hyaena remains show how recently Sicily was joined to Africa.

Reports on the Oxford meeting of BAAS.

Summary

Offers CD a live Proteus anguinus from Adelsberg cave. In his hands it will have a fair chance of developing into "some type of Columbidae (say a pouter or tumbler)".

The Origin is universally praised in Italy and Germany, even by those who disagree with it.

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

Describes an astounding "sort of mis-begotten-bird-creature", the Archaeopteryx, a grand Darwinian case.

His elephant paper is out in Natural History Review [(1863): 43–114].

Comments on his elephant paper

and CD’s observations on dimorphism in Melastomataceae.

Edouard Suess attributes to Oswald Heer and HF the generalisation "That the time during which a new species is formed, is (as a rule) very short in comparison with the time during which it persistently presents the same peculiar specific characters". [Edouard Suess, "Über die Verschiedenheit und die Aufeinanderfolge der tertiären Landfaunen in der Niederung von Wien", Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften in Wien (Math-naturw. Klasse) 47 (1863): 306–31.] [See 4277.]

Summary

Suess’s paper [Edouard Suess, "Über die Verschiedenheit und die Aufeinanderfolge der tertiären Landfaunen in der Niederung von Wien", Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften in Wien (Math–nat. Klasse) 47 (1863): 306–31] which deals directly with natural selection.
