Because of the commanding importance of the subject matter, those of our subscribers who did not read the paper by Vernick and Karon in the May issue of the Journal arc urged to peruse it now. The following solicited editorial by Agranoff and Mauer expands thinking in an area where only discussion and controversy can ultimately lead to progress. Interested readers should next turn to the "Correspondence" column of this issue and take note of a reply "Letter to the Editor" prepared by Vernick and Karon. A last word in this field of professional responsibility and uncertainty has not yet been expostulated. Further comments, if helpful, will receive consideration as "correspondence communications" in forthcoming issues of the Journal. Ed.
