This small compact volume is intended for the use of students of medicine. As much as possible has been eliminated. Bare facts have been put down, and no attempt is made at giving references to the literature. The authors acknowledge reference to other textbooks in the preface. All redundancy has been removed, and the material has been boiled down to the smallest possible quantity. This will serve as a usable book for students. While the illustrations are numerous, most of them are not original, but are taken from other textbooks. If one remembers that this book is not to be used as a reference book, but is to be supplemented by a more extensive textbook on pediatrics, one will be able to recommend it to students in medical schools.
