The kindness extended by reviewers to this book on the occasion of its first appearance, and the steady demand for it since the War, give me reason to hope that this edition will still find a sphere of usefulness among students of anatomy.

A number of reviewers expressed the opinion that the bones of the skull had not been presented so fully " dressed " as were the other constituents of the skeleton. I was quite conscious of this at the time of writing the book, and had put them forward in that way after some reflection, and deliberately. I have thought over the matter again in preparing this edition, and have concluded that the old reasons, those which influenced me before, are at least as potent now, so that I have refrained from an attempt to alter the plan on which the description of the skull was based.

The whole text has been submitted to careful revision, and a few new illustrations added.
