Five lectures on shell shock delivered by Henry R. Humphries. Neither the date nor the location of the lectures is given but from references in the text, they were probably delivered ca. 1919-1920. He discusses possible causes of shell shock, how it differs from other neurological and psychiatric conditions, and the best means for treating it. Several of the lectures include questions asked by the audience and Humphries’ answers
Except for lecture two, the extremely fragile condition of the originals requires researchers to use preservation photocopies.
