The preparation of an introductory textbook of comparative neurology presents special difficulties. That perhaps is why so few people have tried it. Every experienced teacher will agree that personal study of the material in the laboratory by every student is essential. Dr. Papez, accordingly, describes his book as "an introductory course on the form, function and structural interpretation of the nervous system," and instructions for the preparation of illustrative material are given throughout the book.
