This section contains forty-four plates with explanatory tables and legends. As in the first section, all designations and descriptions are given in German, English, French and Spanish. The plates are exceedingly beautiful and to realize the wealth of information they convey it is necessary to see them. This work should be of inestimable value to head surgeons, rhinologists and otolaryngologists as well as to the oral surgeons. Every plate has a cover of cellophane on which are traced in red the details of the films together with numbers corresponding to those in the table of legends on the opposite page. From both the scientific and the esthetic aspect this work cannot be too highly commended.
