Asks about Charles Bell’s statement concerning contraction of eye muscles. Asks whether such contraction is related to secretion of tears.

There is no hurry for information. Delighted that FCD is making experiments.

It was a sincere pleasure to make FCD’s acquaintance.

In a fortnight will begin to arrange notes on expression. Asks for FCD’s conclusions about the contraction of eye muscles. Is interested in abstract of FCD’s experiments on "rate of travelling of the nervous powers".

Expresses sympathy [on death of FCD’s daughter].

Will be grateful for his paper and letter.

Thanks FCD for information.

Hopes that translation of his paper will appear in Dublin Journal.

Notes experience of his son [Leonard Darwin] on engorgement of eyes with blood. Discusses secretion of tears when eye muscles are involuntarily contracted.

Comments on translation of FCD’s paper ["On the action of the eyelids", Arch. Med. 5 (1870): 20–38].

Speculates that closing eyelids may protect eyes from vibrations.

Discusses publication of Expression.

Comments on FCD’s 1848 work [see 7582] in which he came near to anticipating CD.

Comments on FCD’s paper [on action of the eyelids, see 7203]. Asks about contraction or dilation of the iris due to emotional states, illness, or prostration.

Thanks FCD for information about eyes [for Expression].

Must interrupt work on the subject to prepare new edition of Origin [6th].

Comments on gift of a new work by FCD [possibly "Die Projection der Gesichtserscheinung nach der Richtungslinien", Arch. Opthalmol. 17 (1871) Abt. 2: 1–68].

Comments on action of eyes in a person lost in meditation. Asks about Charles Bell’s explanation [in Anatomy of expression (1806, 1844)].

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.

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

Expresses gratitude on election to Royal Netherlands Academy.

Would be impractical to have FCD check references to physiology in proofs [of Expression]. William Bowman has checked chapter on weeping.

Invites FCD to visit Down when he comes to England in July.

Mentions publication of Expression.

Asks whether children born blind ever frown, shed tears, or contract orbicular muscles.

Congratulates FCD on his anniversary [as Professor at Utrecht].

Asks about the effect of atropine on the eye. Is interested in parallel case: influence of phosphate of ammonia on glands of Drosera.

Discusses effect of atropine solution on eye,

and effect of phosphate of ammonia solution on gland of Drosera.

Would like to see work by T. W. Engelmann and possibly one by Dr De Ruyter.
