Congratulates CD on Origin; has been "initiated into an entirely new province of knowledge".

Notes error involving rhinoceros.

Encloses other notes.

Comments on the Origin. Outlines difficulties he finds in CD’s theory. Believes CD must define natural selection more accurately and mentions instances in which that principle is an insufficient cause to account for the form of certain structures.

JDH half through Origin. High praise for facts and reasoning.

Lyell told JDH his criticisms: small matters JDH did not appreciate.

Reactions of G. Bentham, J. S. Henslow, and C. C. Babington.

Forwards letter from Asa Gray.

Bentham is very agitated by Origin. CD over-emphasises natural selection. His theory accounts for too much and would be improved by unburdening it of natural selection.

Cannot agree with all of CD’s views [in Origin].

Thinks too much is made of the Galapagos. The peculiarity of their ornithology will break down.

Offers to answer any questions on ornithology.
