Excerpt from Practical Physiological Chemistry MY colleague's book, in its earlier editions, received so hearty and so general a welcome that any personal words of recommendation seem now uncalled for. In this edition, however, it emerges as a work of a somewhat different order. Like all good books which deal with a progressive subject, it has felt the growth impulse, and, notwithstanding the exceptional nature of the times, material for growth has during the last few years accumulated in abundance. If this edition has largely out grown its predecessors the increase is not only desirable, but, in my Opinion, necessary. Progress in any science calls continuously for new methods, and for extension and improvement in technique. In the growth of any branch of knowledge there are, indeed, periods when the development of technique becomes the most pressing of needs, and its success the best measure of progress. Biochemistry has been successfully passing through such a period. Its methods have been greatly multiplied, extended and improved. We are now beginning to reap the reward in the accumulation of accurate quantitative data. One need peculiar to biochemistry, that of following changes in living tissues without terminating the life of the animal, or harming the human subject, has now been largely met, at least so far as studies of the blood are concerned. This is due to the success of micro-methods of analysis. 80 significant are some of the results which can be obtained that we may hope to see the methods become as general in connexion with medical diagnosis as the use of the stethoscope or the electrocardiogram.
