Is honoured by his election to the Philosophical Club [of the Royal Society].

Makes arrangements to call.

Sorry he missed CD when he called. Suggests a time he can call.

Responds to CD’s criticism of his handling of adaptation theory [in Rep. BAAS 26 (1866): liii–lxxxi].

Sends a "remarkable" enclosure [missing], evidently by a working man, which will interest CD as "shewing that ideas are spread".

Asks CD to breakfast in London on Tuesday [24 Mar].

Arranges to call on WRG.

He and another Bencher of Lincoln’s Inn have signed the necessary certificates for admission of CD’s son [George].

Has never before noticed with care the markings on finger-ends. Compares them to the complex whirl-pool patterns of human foetal lanugo.

Mammae in human males.

The role of natural selection in the development of beards and manes of animals.

Hereditary pointing in setters.

Does not think WRG’s theory [about ridges of skin on palm and finger-ends?] will hold.

Does not believe the beard in monkeys and goats could be protective like the lion’s mane.

Thanks him for fact about setters.

Is perplexed about the reported milk secretion in pubescent boys.
