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".

Sends CD a volume of West Riding Lunatic Asylum Medical Reports [1 (1871)], which contains some observations on blushing.

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

Is just recommencing his essay on expression.

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

Thanks for Expression. Will write paper on it in next [July] West Riding Asylum Medical Report.

Sends photos of lunatics;

will send notes corroborative of CD’s views, including some on "hereditarily transmitted movements".

Pleased that JC-B will review Expression.

Fears he will not be able to improve the book with JC-B’s "wonderfully curious" photographs because Murray printed such a large edition.

Would be glad to have JC-B’s notes on inheritance – "a most important subject".

Sends 15 studies in expression, acted by his wife.

Describes David Ferrier’s experiments on electrical brain stimulation of animals; these show direct relation between convolutions of the brain and groups of muscles [West Riding Asylum Med. Rep. (July 1873)].

Photographs sent by JC-B show great power of acting.

David Ferrier’s researches sound wonderful. Does he believe that he excites an idea and this leads to the movement, or that he acts directly on the motor nerves?

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.

Thanks CD for his praise of West Riding Asylum Medical Reports.

Hopes CD will come to Asylum if he attends BAAS meeting at Bradford.

Is about to undertake an intensive investigation with other scientists of general paralysis in its various aspects. Would appreciate CD’s comments on photographs he would submit.

Will do what he can to help JC-B with his work on expression of patients suffering from general paralysis.

Requests help for George Darwin’s investigation of marriages of first cousins. Seeks to determine proportion of first-cousin offspring among the insane, deaf and dumb, blind, etc.

Thanks JC-B for copy of Medical Reports of the West Riding Lunatic Asylum.

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.

Thanks for 5th volume of the West Riding Asylum Medical Reports.
