The book begins with a brief but complete resume of the history of diphtheria, and then continues with the etiology and immunity of the organism. The clinical diagnosis is well discussed, with a complete description of the many lesions. As is usual in French textbooks, the bacteriology is well discussed and illustrated. The treatment also includes a full description of the methods of intubation, as well as the complications that may result from reactions to the serum. This book is complete, and the subject matter is easily accessible. The illustrations are drawings, but these are so simple that their meaning is made clearer than could possibly be done with photographs.
