Price of Expression is 12s.

Is amazed at Expression. Like CD’s former works, it contains the material and principles of a new science.

The Zoological Station is making good progress – now has a fine building. Hopes for a stable income from contributions of various governments.

Agrees the rabbit experiment has gone on long enough, but would like one more litter.

Appreciation [of Expression]. ARW will review it in Quarterly Journal of Science [n.s. 3 (1873): 113–18].

The Michelets are ill and dispirited.

Has just read Origin and Descent and wants to know: 1. Has man a soul? 2. Is man morally responsible "to his creative cause or force"? 3. Is there any form of after-life?

Thanks CD for Expression. Disagrees with his views on the genesis of melody; HS gives some reasons for believing it to originate in the natural cadences of emotional speech.

Lemmings in Norway.

Discusses his theories on heredity and on the "soul" as the governor of mental and physical development.

Thanks for Louisville Courier Journal.

Proposes establishing a quarterly journal for longer, illustrated articles of some popular appeal. Seeks CD’s support.

Thanks for Expression.

J. J. Moulinié’s translations of Descent and Origin required much reworking, which accounts for delays.

Thanks for copy of Expression.

Thanks for Expression, which he received through Asa Gray.

Relates some personal experiences of unconscious sympathy.

Has read a review of Expression and finds CD’s explanation of "antithesis" [see Expression, p. 50] unsatisfactory. Proposes a theory of upward lines expressing energy and downward lines expressing the reverse.

Acknowledges presentation copy [of Expression], which is not to be found in the market.

Interested in CD’s opinion of her article ["The consciousness of dogs", Q. Rev. 133 (1872): 419–51].
