About to go to press with "wearyful" Fossil Cirripedia [vol. 1 (1851)];

would like to borrow proof-sheets of Frederick Dixon’s work [The geology and fossils of the Tertiary and Cretaceous formations of Sussex (1850)]. Would also like to borrow a specimen of Balanus glacialis from Royal College of Surgeons. Encloses formal request [see 1356].

Asks to borrow specimen of Balanus glacialis from the Museum of the Royal College of Surgeons. It will be necessary to disarticulate it, but CD will return the valves to the Museum.

Gratified by what RO says about his book [Living Cirripedia, vol. 1 (1851)]. The anatomical work is the only part he is really interested in; finds the "mere systematic part infinitely tedious"; but will be surprised if he is ever proved wrong on the males of Ibla and Scalpellum.

Sends source of description of swimming bear catching insects [Samuel Hearne, A journey from Prince of Wales’s Fort in Hudson’s Bay to the northern ocean … (1795); see Origin, p. 184].

Responds to Owen’s remarks that his book [Origin] is not likely to be true because it attempts to explain so much. CD describes how, for fear this might be so, he resolved to give up the work if he could not convince two or three competent judges. He is sensitive because of unjust things said by a distinguished friend [A. Sedgwick]. Value of his views now depends on men eminent in science.
