In many present day treatises, the clinical side of medicine is so lost in a maze of scientific speculation that it is a relief to take up this book by the dean of Scottish pediatricians. The wealth of clinical experience and the keenness of perception which these pages reveal is rarely encountered. Laboratory diagnostic methods are not ignored, but are given their rightful place as adjuvants to examination of the patient. The patient is always before the reader, not the disease. If one expects an exhaustive discussion of the whole field of pediatrics, the book will not satisfy. For instance, contagious diseases are only rather casually mentioned. But if his desire be to have a word picture of the disease manifestations in the sick child, he will look far before he finds one that is better. The illustrations are numerous and well chosen to depict the conditions which they elucidate.
