Summary

Asks JC-B to read CD’s MS on confusion of mind, which often or generally accompanies blushing.

Summary

Has sent photographs of insane woman to be engraved. Assumes JC-B has no objection.

Is making immense use of JC-B’s MS. The book ought to be described as "by Darwin & Browne".

Summary

JC-B’s MS most useful.

P. Gratiolet’s observations on contraction and dilation of pupils of eye of a person in extreme terror. Has JC-B ever observed this? Expression has been his hobby-horse for 30 years.

Summary

Thanks for information about blushing of idiots.

Case of pregnant woman "truly wonderful".

Thanks for photographs.

Has found London photographer, O. G. Rejlander, with passion for photographing expression.

Received information about iris of eye from F. C. Donders; shows contraction and dilation of pupil is very complex.

Summary

Comments on notes by JC-B on relation between blushing and mental disturbance. Asks for further information about blushing. "The single pencil line down this MS is my mark that I have used it once."

Thanks for "dreadful photo of the imbeciles".

Summary

Discusses blushing. CD believes confusion of mind alone can account for it. Sends MS for JC-B’s comments and corrections.

Summary

Asks JC-B to observe whether platysma muscle contracts during rigor or shivering fit.

Is just recommencing his essay on expression.

Summary

Asks whether capillary circulation is ever influenced by the mind’s being directed intently to any part of the body.

Has JC-B ever seen idiots blush? JC-B’s MS on blushing is capital.

Comments on Henry Maudsley [Body and mind (1870)].

Pointed ears in the insane.

Discusses LR’s communication concerning supernumerary mammae.

Summary

States his very high opinion of [JC-B’s?] abilities as judged from his writings and many excellent letters, and his suitability for some post in histology and pathology.

Discusses movement of ears and contraction of the platysma.

Discusses phyllotaxy, citing work of Carl Nägeli and Chauncey Wright.

Summary

Gives permission for the photographer to come to Down, but states that O. J. Rejlander has recently taken several photographs of him which would be available to purchasers.

Summary

Thanks JC-B for volume of Asylum reports and paper on epilepsy. Seems clear from reports that physiology of brain will soon be largely understood.

Summary

Duchenne [Mécanisme] has arrived. Has been testing the photographs with 20 or 30 persons; when all or nearly all agree with Duchenne, CD trusts him. Not one understood the "contracted pyramidal of the nose". CD does not think the so-called muscle of lasciviousness worth exhibiting.

His MS [of Descent] is so large he may print only what he has, and make a second volume of what he is now writing on expression.

Discusses photographs he would like to have: baby screaming, person in paroxysm of fear.

Summary

Asks TW to persuade painters to observe how far down body blush extends on models.

Summary

Discusses loss of voluntary movement of ears in man and monkey.

Summary

Discusses errors in Descent. Not surprised that WT is not committed to full acceptance of evolution of man.

At work on Expression. Asks about muscles that raise spines of hedgehog and tail coverts of peacock. Asks about influence of mind on capillaries with regard to blushing. Mentions views of James Paget on influence of the mind on nutrition of body parts.

Summary

Hopes JC-B thinks that CD has properly acknowledged his debt in Expression.

Summary

Thanks WO for information on platysma, which he did not know could be brought into voluntary action. Is coming to believe it has nothing to do with expression.

On the relation between white colouring and susceptibility to poisonous plants, CD suggests WO send his paper to J. Wyman and propose he investigate whether white as well as black pigs will eat paint-root.
