Thanks CD for Descent.
Sends a copy of his oratio inauguralis on De harmonie van het dierlijke leven [1848] in which he espoused evolution, but did not see the influence of natural selection.

Answers to CD’s queries will take time. CD may not be aware of the influence of accommodation on the diameter of the pupil of the eye. Parrots, for example, contract or dilate the pupil independently of amount of light [see Expression, p. 304]. Sends his book on the subject [On the anomalies of accommodation and refraction of the eye (1864)].
Replies to CD’s queries on movement of the eyes in meditation, and changes in the iris in rage and terror [see Expression, pp. 229, 304].
His analysis and explanation of the fact, observed by Charles Bell, that the eyeballs are turned upwards and inwards when consciousness begins to fail.
Protests against CD’s statement that FCD’s letter will make him "strike out a good deal". He would never pardon himself for being the cause of any suppression by CD. It is for specialists to put their knowledge at CD’s service. He is mistaken if he thinks a knowledge of physiology is sufficient for writing a book on expression. It is CD’s conception and spirit that all await. Offers to read those parts of the proofs of Expression dealing with physiology.
Royal Netherlands Academy of Science has elected CD.
Thanks CD for invitation but declines because of his need for a rest instead of coming to England in July.
Repeats his offer to help CD at any time. "I am always learning by trying to answer your questions."
Thanks CD for copy of Expression.
Agrees to observe expression in children born blind.
On hearing of CD’s work with Drosera, tells of his experiment showing extreme sensitivity of the iris of a dog’s eye to atropine. [See Insectivorous plants, p. 173.]
