His analysis and explanation of the fact, observed by Charles Bell, that the eyeballs are turned upwards and inwards when consciousness begins to fail.

Thanks FCD for information, which will make him "strike out a good deal".

Has received German pamphlet.

Will read work by John Soelberg Wells [? A treatise on the diseases of the eye (1869, 1870)].

Discusses his work on expression.

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.

Thanks FCD for suggested deletions in MS of Expression. Declines offer from FCD to examine proofs also.

Royal Netherlands Academy of Science has elected CD.

Expresses gratitude on election to Royal Netherlands Academy.
