All neurologists know the difficulties in diagnosticating epilepsy in the absence of opportunities to see attacks and to receive the carefully analyzed statement of the observers of the patient. All this and much more is well brought out in the chapter on the epileptoses. Many epileptics found their way into the armies either through the carelessness of examiners or by suppression of the facts on the part of those who desired to serve. The fact that an imbecile can shoot straight and face fire comes out in one or two places, but this does not seem to prove that a good rifleman is necessarily an all-round good soldier. A book like Dr. Southard’s could be made of much use in teaching students, especially postgraduates, by having them, when a particular subject like epilepsy or schizophrenia, for instance, is under discussion, use as collateral reading the case reports of this work. Dr. Southard’s book will prove useful to many workers--to the medical officer whose duty it is to examine recruits for the service or to pass upon and treat them while in service; almost equally to the medical officer in time of peace; to authors of textbooks and treatises and to contributors to neurological and psychiatric journals; to lecturers and clinical demonstrators; to the examiner for the juvenile courts; and to members of the psychopathic, psychiatric, and neurological staffs of our hospitals. One is not called upon in an introduction to review at length the contents of the volume, but it may prove of value to the reader to dip here and there into the pages of the work to which his attention is being invited. It will be remembered that fifty years ago and much later, down to the time of Babinski’s active propaganda in favor of the theories of suggestion, counter-suggestion, and persuasion in hysteria, various affections of a vasomotor and thermic type were included in the list of hysterical phenomena. These and some other phenomena sometimes classed as hysterical, Babinski and those who accord with him now find it necessary to sweep entirely from the domain of hysteria, which being produced by suggestion and cured by counter-suggestion or persuasion cannot include symptoms which are beyond the control of the will and intellect of the patient. According to the new or rather revived pronouncement, these must be due either to definite organic lesion, or to a disorder of reflex origin, connoting the occurrence of changes in the nervous centers as long ago taught by Vulpian and Charcot. In the records of cases and in the discussions thereon this differentiation receives much consideration.
