His admiration for HF’s paper on American fossil elephant.
Notes "temporary irruption of S. American forms into N. America".
Rejoices that HF has "smashed" case of Mastodon on Timor.

Answers CD’s query on the free digits of Archaeopteryx.
Jaw with teeth found associated with Archaeopteryx fossil. Waterhouse pronounces it a fish’s jaw.
If jaw belongs to Archaeopteryx, it will show great peculiarity. A German author has advanced the case as argument for Origin.
Has been in France, conveys good wishes from Quatrefages.
Describes the fossil of an unusual mammal head from Brazil.
Good of HF to tell him about Brazilian beast. So intermediate a form is "very glorious". Must assume it is very old.

Sends information about Pliocene fauna of the "Forest Bed" of the Norfolk coast.
A genus described as extinct by Owen is found by E. A. I. H. Lartet to exist in Russia.
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.]
Thanks for information about Pliocene mammal. Interested in relating process of formation to duration of the species. Oswald Heer’s view that species suddenly formed surely false.
Bad summer with much sickness. Going to Malvern [for water-cure] for a month.
Muddled over phyllotaxy and made out nothing.
HF will send E. 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.
Sends address.
