In this book the same careful clinical observation and clinical judgment that made Joslin's original treatment of diabetes so popular are evident. Dr. White adopts the same methods, and as a result the book contains practically all that is now known about the various phases of diabetes in childhood. The thesis maintained is that "the care of the diabetic child resolves itself mainly into three factors: (1) the maintenance of the normal physiological processes of the growing and developing organism; (2) the prevention of the accidents of diabetes; (3) the eventual production of an individual who will be an economic and a social asset." Their observations are based on approximately 750 patients. The text is too full of details to warrant more than a general statement that no one treating diabetes in childhood or adolescence can well do without this book.
