This monograph on the late stages of epidemic encephalitis belongs in the large series known as "La pratique médicale illustrée" edited by Sergent, Mignot and Turpin. It is based on the extensive personal experience of the authors and on quite complete study of the literature, both French and foreign. There are chapters on the parkinsonian syndrome, dystonias, abnormal movements, sensory disturbances, vegetative disorders, psychic disorders, clinical forms, diagnosis and treatment. Each subject is necessarily treated in a condensed manner but with only few omissions of data of any importance, as, for instance, when it is stated (page 64) that modifications of basal metabolism have not been observed in the various post-encephalitic syndromes, though decided modifications were observed in twenty-eight of forty-seven cases reported from America by Naccarati in 1926. The book deals entirely with the clinical side, including treatment; the pathology is not discussed.
