Congratulates THH on first number of Natural History Review.

THH’s article on brain ["On the zoological relations of man with the lower animals", Nat. Hist. Rev. (1861): 67–84] completely smashes Owen.

Owen’s Leeds address [Rep. BAAS (1858): xlix–cx].

In his historical sketch of opinion on species CD has picked out some sentences [by Owen] with which he will take some revenge. CD is not bold enough to come to an open quarrel.

Chauncey Wright’s review of Origin: A. Gray asks that THH append a list of philosophical books on subject if he accepts it for Natural History Review.

Sends Gray’s pamphlet of his (republished) reviews [Natural selection not inconsistent with natural theology (1861)] for notice.

Invites Mrs Huxley and the children to spend a fortnight at Down.

MS of Chauncey Wright’s review has not yet arrived.

[P.S. missing from original.]

Does not think much of the arguments of the Duke [of Argyll], though liberal and complimentary to himself.

THH’s Athenæum letter ["Man and the apes", 30 Mar 1861, p. 433] almost too civil. What a thorn THH must be to Owen.

Chauncey Wright’s review of Origin.

Family plans for Torquay in summer.

J. S. Henslow’s death.

Mr Campbell (recommended by H. Spencer) would be a treasure but doubts any man has patience to experiment at another’s suggestion.

Owen’s new résumé of his brain doctrine ["On the cerebral character of man and ape", Ann. & Mag. Nat. Hist. 3d ser. 7 (1861): 456–8]; an attack on CD’s views. Quotes Owen on cavillers and controversialists.
