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 and
resources as our experience leads us to believe will prove of permanent
value in civil practice.

For the rest, the text has been revised, condensed, and in places
rearranged; a number of old illustrations have been discarded, and a
greater number of new ones added. Descriptions of operative procedures
have been omitted from the _Manual_, as they are to be found in the
companion volume on _Operative Surgery_, the third edition of which
appeared some months ago.

We have retained the Basle anatomical nomenclature, as extended
experience has confirmed our preference for it. For the convenience of
readers who still employ the old terms, these are given in brackets
after the new.

This edition of the _Manual_ appears in three volumes; the first being
devoted to General Surgery, the other two to Regional Surgery. This
arrangement has enabled us to deal in a more consecutive manner than
