from the editors Although we may have " theme" issues in the future, the fact that the three papers, by Michael Schmidt, S. Morris Engel and Gary Jason, and Michael Schmidt's bibliography in this issue are about fallacies is a matter of happy happenstance, not design . E .P . Brandon ' s paper on ellipsis is therefore as much at home here as the others. We draw your attention to Schmidt's excellent bibliography and to his re- quest for information about items he has overlooked . Is one of your favorites not included? Worse yet, is one of your papers missing? Please send additions and corrections to Michael Schmidt, directly or through this journal. D IN MEMORIAM It is with great sadness that the editors have learned of the death of Professor Merrill Hintikka on January 1, 1987, after a short illness . Her vitality, wit and good judgement will all be sorely missed by those who had the privilege of knowing her . We are grateful for the support she gave to informal logic by serving on the editorial board of this journal. We extend our heartfelt condolences to her husband, Pro- fessor J aakko Hi nti kka.
