From F. C. Donders 17 April 1872
Summary
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.

From F. C. Donders 17 May 1870
Summary
The illness and death of his daughter have delayed his answers to CD’s queries. He has, however, worked on the circulation of the eye and has almost finished a paper on it, which he will send to CD. In general, the views of Charles Bell are confirmed.
As for CD’s second query, he doubts that the relationship exists, but will answer fully in next letter.

From F. C. Donders 27 May 1870
Summary
Has finished the article [on the action of the eyelids in Ned. Arch. Geneeskd. & Natuurkd. 5 (1870), also see 7238]; summarises: the occlusion of the eyelids protects the vessels, and the eye itself, against the danger of pressure caused by excessive expiratory action. The weakness of the conclusion is that the extent of the danger caused by the pressure to the normal state of the eye is not precisely known.
