Praise for and detailed comments on Expression.

Two cases of coloration in animals – one from sexual selection, the other helping to procure prey [see Descent, 2d ed., pp. 542–3].

Thanks for HR’s valuable remarks about Expression, and returns HRs copy, signed.

Discusses some of HR’s anecdotes about children sucking their tongues.

Admits that the youth who trembled so that he could not reload his gun after killing his first snipe was himself, when a school-boy.

Insists that suckling babies pound and scratch mothers’ breasts. Perhaps CD’s evidence to the contrary comes from ladies, who only expose small portion of bosom, as opposed to working-class women.
