Asa Gray’s suggestion that variation was directed by a higher power and Herschel’s view of providential arrangement in nature.

Compares variation in domestic and wild species.

Asks JL’s advice about details of William’s proposed banking partnership. CD’s solicitor is suspicious of Atherley’s long-term intentions.

Bentham has sent a damaged spurless Orchis pyramidalis; asks CL to send another. Fears they are irregular monsters. [See Orchids, pp. 47–8.]

JL is thinking of moving to Brighton.

As a general rule CD thinks it best to deposit specimens in the British Museum, and "bitterly regrets" he did not send all his specimens there. Nevertheless he agrees to sending his crustaceans to the Oxford Museum.
