PREFACE.

THESE Lectures have been written out for publication in deference to the wishes of a number of, perhaps too partial, friends. They comprise the results of a good many years of observation, both in hospital and private practice. The author's design has been to render them simple, intelligible, and practical. If they should prove to be useful, his object will have been fully attained.
