Arranges to visit CD at Down.

Recommends J. C. Houzeau’s Études sur les facultés mentales des animaux [1872].

Was glad to make CW’s acquaintance.

Discusses the mental powers and habits of animals and considers that those of man are not separated from those of animals by any sort of fundamental barrier; the gulf seems formidable only from a self-conscious, human point of view. Man’s important distinction is his greater ability to act and respond independently of external stimuli, in consequence of his internal accumulation of personal experience.
