Glad to hear good news of Etty [Henrietta Darwin].

CD’s observations on Scaevola are capital. The indusium collects the pollen and is the homologue of the pollen-collecting hairs of Campanula. A boat-shaped organ forms a second indusium, the inside base of which forms the stigmatic surface. The latter later protrudes as horns, forming the stigma.

Describes W. H. Harvey’s scientific career and thinks his letter interesting. Agrees with Harvey that the primary agency of natural selection is as great a mystery as ever. [Response to 2823.]

Rejects CD’s comparison of natural selection with the architect of a building. The architect who plans and oversees construction should not be confused in his function with the wisest breeder. That would be to deify natural selection.

Observations on moths visiting flowers.

Has not received any replies from the parties.

Either he or his son will value the property after JH’s return to Alford.

Sends a plan of the Anwick Estate: will value it on Saturday next (23 June 1860).

Will purchase it for CD at the auction on 25 June if he can secure favourable terms.

Sees Huxley’s deification of matter and force as a reaction to the way Paley likened the "Unknown Cause" to the mind of man so that new causes could be introduced. If you wish to retain free will which is inconsistent with constant law, Paley’s position is better. Free will is a recently introduced cause on our planet. It cannot be fully attributed to secondary causes.

What CD says about the variation in gestation of the hound is remarkable.

The astonishing fertile rabbit–hare hybrids encourage belief in Pallas’s theory of the multiple origin of dogs.

Does the regularity of gestation in man indicate a common stock?

Hooker’s observation of absence of forms peculiar to extra-Arctic Greenland indicates that the time since the beginning of the glacial period is brief in geological terms.

Hopes to make observations on moths pollinating clovers.
