Editorial

Guest Editor This issue of Anesthesia Progress was edited by Mr. Henry Koehler. Your regular Editor is on a lecture tour in New Zealand, Australia and the Orient. Mr. Koehler graciously accepted the assignment to insure the timely publication of our Journal. Henry Koehler is one of our most creative and tireless workers in the field of dental journalism. Officially, he is Editor of Oral Research Abstracts, published by the American Dental Association. ORA abstracts the pertinent dental literature from many American and international foreign language journals. It is fundamental to progress in any field that the widest sort of idea-exchange be encouraged. This concept has been one of Henry Koehler's goals for many years. Mr. Koehler's scientific abstracts of the literature in anesthesiology and pain control have appeared in every issue of Anesthesia Progress (except one) for the past 15 years. We are thankful for his enormous capacity and cooperation. And it's about time we recognized the contributions of Mr. Koehler and others who make it possible to produce Anesthesia Progress. Mlany thanks, Henry. N.T.
