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.
