ADDRESSES AND OTHER PAPERS BY WILLIAM WILLIAMS KEEN M.D., LL.D., F.R.C.S. (HON.) Professor of Surgery, Jefferson Medical College, Philadelphia; Membre Ehren- mitglied der Deutschen Gesellschaft für Chirurgie; Honorary PREFACE. These occasional addresses and other papers are published in the hope that they may prove useful both to the profession and to the public and in response to numerous requests. I trust that a few repetitions will be forgiven inasmuch as the audiences were different and the facts important. Of course the statistics and allusions to current events must be read as of the date when the addresses were originally delivered and not of the date of the present volume. I have to thank the Editors and Publishers of the various periodicals and books in which some of the papers first appeared for permission to republish them. PHILADELPHIA, May 8, 1905. WILLIAM W. KEEN. |
