This is not only a valuable and convenient monograph for those interested in the subject, but so far as we know the only collective work in this restricted field. First, the author gives an excellent description, with illustrative cases, of acquired word-blindness. A brief history of our knowledge of this particular defect as a congenital condition and a statement of the symptomatology follow. Cases are then reported. Finally there is an account of the syndrome as a family or hereditary occurrence, and a consideration of prognosis and treatment. The book should be on the shelves of every neurologist and pediatrician, and the principal features of the syndrome in a compartment of his memory.
