Summary:
The variations of Peronea caused A. H. Haworth and J. F. Stephens to create 30 or 40 species based on colour and markings. HD was first to be convinced these would be reduced to two.
Discusses species that closely resemble one another;
cites species that differ in variation in different localities;
in some double-brooded species the broods differ markedly in size and colour.
Encloses his list of varieties of Peronea.

Summary:
Birth of his sixth son [C. W. Darwin]. It is dreadful "to think of all the sendings to school and the professions afterwards".
CD is not well but has not the courage for water-cure again; trying mineral acids.
Working hard on the book [Natural selection]; is overwhelmed with riches in facts and interested in way facts fall into groups.
To his surprise [Helix pomatia] has withstood 14 days in salt water.
Pigeons’ skins come in from all parts of the world.
