PREFACE TO THE THIRD EDITION.

The demand for another edition of this Compend, so gratifying to the writer, has made it necessary to thoroughly revise the work.

To keep pace with the progress of the branch of medicine of which it treats much new matter has been added, and many subjects have been entirely re-written; especially the articles on Antiseptic Surgery, Mortification and Gangrene, Urethrotomy, Burns and Scalds, Venereal Diseases, Retention of Urine, and Inflammation.

The illustrations are taken, by permission, from the standard works on Surgery.

The matter embraced under the head of "Diseases of the Eye and its Appendages," has been omitted, because there has recently been added to the Quiz-Compend series a volume devoted entirely to these subjects.
