Summary
CD’s questions [on expression] are more difficult than he thought and have led him further afield than he expected. If CD is not hurried, he promises less imperfect answers in six weeks. Thanks CD for drawing his attention to a really important question from different points of view.

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.
