Much has happened since this Manual was last revised, and many surgical lessons have been learned in the hard school of war. Some may yet have to be unlearned, and others have but little bearing on the problems presented to the civilian surgeon. Save in its broadest principles, the surgery of warfare is a thing apart from the general surgery of civil life, and the exhaustive literature now available on every aspect of it makes it unnecessary that it should receive detailed consideration in a manual for students. In preparing this new edition, therefore, we have endeavoured to incorporate only such additions to our knowledge.
