In looking over the literature of the histology of lethargic encephalitis which has accumulated during the last few years, it was of interest to note that no one has made mention of the inflammatory changes which may occur in the cranial nerves in these cases. Since this fact may be of importance in clearing up and explaining many of the clinical symptoms, in subsequently giving aid for the solution of the etiology of this affection and in differentiating it pathologically from acute poliomyelitis, it became of interest to study more carefully the material obtained from the necropsies made in three cases and to report the findings with abstracts of the clinical histories. These cases were treated and died in the Barnes Hospital, and the abstracts of the clinical histories reported in this paper are taken from the histories which are filed there.
