In the second edition, this valuable primer has been entirely revised and reedited. It is emphasized that the purpose of the primer is not to standardize the treatment of fractures but to suggest what, in the opinion of the cooperative committee on fractures, constitute acceptable methods of treatment. Blank pages are interspersed so that the student may make notes to amplify the material presented by the instructor. Four new topics are included in this edition: compression fracture of the spine, fracture of the skull, active movements in the treatment of fractures, and massage during the treatment of fractures. The book begins with how to make plaster-of-paris bandages and ends with splints and accessories for the doctor's automobile and office. The illustrations are effective. Many of the statements, epigrams and admonitions printed in large type are excellent. The primer was not intended to be an encyclopedia of the treatment of fractures.
