When a book grows to be forty years old, one of the problems it faces is how to avoid passage into a condition once described by President Theodore Roosevelt as the state of innocuous desuetude. Dr. Hawk's textbook appears to have found the answer in an entirely satisfactory manner.
In 1907, when Dr. Hawk was demonstrator of physiologic chemistry in the department of medicine at the University of Pennsylvania, he made time to write the first edition. This was before the days of the Archives, but The Journal of the American Medical Association reviewed the book at once. The review described it as something more than an ordinary laboratory manual and something less than a thorough treatise on physiologic chemistry. Besides giving helpful directions for mapping a systematic course in this complicated subject, it described technics and gave an intelligent discussion of recent advances in the entire field of biochemistry.
