This is a convenient epitome of the principal facts in regard to nervous diseases, and, allowing for the brevity of the descriptions, a good one. The author has the art of clear description and the schematic diagrams given are well chosen and useful. The section on mental disorders is necessarily less satisfactory than that on nervous diseases. The author mostly follows the text-books of past years, and the result is that his exposition of the facts concerning insanity is not quite the most modern. The conception of confusional insanity, for example, obtained by reading this book, will scarcely be an adequate one. In most respects, however, and more especially in the part relating to nervous diseases proper, the volume will be a convenient and reliable work to freshen the memory of the student or practitioner.
