Note accompanying MS of part of chapter 11 ["Geographical distribution"] of Natural selection [1975].
Finds his grief over his daughter Anne’s death still strong.
Is following Lyell’s advice about publishing his species doctrine. It is not to be a sketch, however, but as perfect as his 19 years of work will allow. His work on pigeons has been invaluable on many points. "No subject gives me so much trouble as means of dispersal of terrestrial production in the oceanic islands."
Finds "most remarkable differences" in skeletons of rabbits.
Offers TCE dog’s skin and skull received from W. F. Daniell in West Africa.
Mentions his experiments involving hawk pellets in seed distribution.
Reminds TCE about pig crosses and incisors.
Agrees with JDH that Cytisus report [presumably of a large change] not sound. CD pleased because, if true, species would change too quickly.
Responds to CD’s queries on Sierra Leone: fertility of European animals introduced to W. Africa, relationship of health and complexion of Europeans, etc.
The bearer has called for the books. Requests volumes of Isis for 1828 and 1829.

Thanks AG for the first part of his "Statistics [of the flora of the northern U. S.", Am. J. Sci. 2d ser. 22 (1856): 204–32; 2d ser. 23 (1857): 62–84, 369–403]
and for information on social and varying plants.
Would like to know number of genera of introduced plants in U. S.
Is surprised at some affinities of northern U. S. flora and asks for any climatic explanations.
Asks what proportion of genera common to U. S. and Europe are mundane.
Is glad AG will work out the northern ranges of the European species and the ranges of species with regard to size of genera.
Has received fowls from interior of Sierra Leone.
African fowls from Sierra Leone are pugnacious and amorous.
CD sorry he had to leave the Hookers abruptly to catch his train.
Has taken birds with seeds in crops to Zoological Society and fed them to eagles and owls. Pellets with seeds in perfect condition were "thrown up" in 18 and 16 hours, showing an effective means of distribution.
Asks WDF to write to his nephew in Jamaica to try experiments with floating lizards’ and snakes’ eggs in sea-water, to see if they survive.
