Thanks LJ for his letter on Origin. Finds LJ agrees with him more than CD had expected.

Discusses problems of geological record, single primordial form, and man.

No summary available.

CD has sent to printer proofs of his contribution to Memoir of Henslow.

Thanks LJ for Memoir of Henslow; thinks it will be invaluable as an example to other clergymen.

Asks LJ which British birds are polygamous. His query relates to the possession by the male of secondary sexual characters.

CD is also interested in the numerical proportion of the sexes in birds.

Asks about the use of the horns in male lamellicorn or coprophagous beetles.

Thanks LJ for his useful facts. Will "look to" the reference about the nightingale.

Thanks LB for his essay on local biology.

CD with much care and discomfort is now able to work a few hours almost every day.

CD doubts that he will be able to do much more that is new, but cannot bear idleness. Has great amount of material on variation under nature, but so much has been published since the appearance of the Origin that he doubts he has the power of mind to render the mass into a digested whole.
