Thinks Wallace memorial should not be presented to Lord Aberdare, nor to Owen, for signature, but will follow THH’s wishes.

Has asked Hooker to sign the Wallace memorial and send it on to THH.

Read splendid lecture by THH on evolution in the Times ["On the application of the laws of evolution to the arrangement of the Vertebrata and more particularly of the Mammalia", Proc. Zool. Soc. Lond. (1880): 649–62].

Has obtained signatures for the memorial. Wonders whether Gladstone would see a deputation and offers to write to Gladstone instead. Asks THH’s advice.

Success of the memorial for Wallace. Sends letter from Gladstone.

Congratulates THH on appointment as Inspector of Fisheries.

Congratulates CD on success of Wallace memorial.

Butler has attacked again.

Asks THH to sign a certificate of nomination to Geological Society for his son William, if an interest in geology is still enough to qualify for election.

CD tells how it came about that Anthony Rich bequeathed his house and land to THH.

Has had letter from Rothenburg asking him to help obtain a grant for Haeckel’s expedition to Ceylon.

CD has offered Ernst Haeckel £100 but does not know where to get further aid. Sorry to hear about Du Bois-Reymond, but is not in the least surprised about R. Virchow.

Erasmus has left half his fortune to CD. Anthony Rich nevertheless insists on keeping to his testamentary arrangements. He also referred to leaving some additional property to THH.

Thanks for Science and culture [1881].

Refers to "Automatism" ["On the hypothesis that animals are automata"], wishing THH could review himself and answer himself and thus go on ad infinitum to the joy and instruction of the world.

Feels better. Grateful for THH’s kind letter. Wishes there were more automata like him.

Thanks THH for the delightful evening he gave Frank [Darwin].

Thanks for report [on echinoderms, Ann. & Mag. Nat. Hist. 2d ser. 8 (1851): 1–19]. Wanted to learn about metamorphosis of the class. Agrees with THH’s distinction between individuals and zooids, but thinks zooids will never cease to be called individuals.

Testimonial for THH’s application for Chair in Natural History at Toronto.

Proposes to send THH vol. 1 of Living Cirripedia.

On THH’s paper on cephalous Mollusca [Philos. Trans. R. Soc. Lond. 143 (1853) pt 1: 29–66]. Discovery of the type or "idea" (in THH’s sense, not Owen’s or Agassiz’s) is one of the highest ends of natural history.

Discusses anamorphism;

position of heart in Cleodora.

Variability within species;

cementing process in cirripedes.

Offers to send Ascidia specimens of Beagle voyage. Describes some of them.

Hopes THH will review his book [Living Cirripedia, vol. 1] which has been published for a year with no notice taken of it except briefly by Dana.

Discusses Limulus-like larva. "I have become a man of one idea.– cirripedes morning & night."

Second Living Cirripedia volume published. Asks THH’s advice on presentation copies for continental naturalists.

THH’s review of Vestiges of creation in [Br. & Foreign Med.-Chir. Rev. 13 (1854)]. CD is almost as unorthodox on species as the author of Vestiges, but hopes not quite so unphilosophical.

Hopes L. Agassiz was sounder on embryological stages than THH thinks.

Agrees with THH on metamorphosis of branchiae of Balanus, and on his view of Owen.
