narrow the gap between what is happening in the research laboratories and what is taught to undergraduate students. Curriculums that do not refiect the state of the discipline are grossly unfair to the student in terms of his being forced to expend much time and effort to make up deficiencies at a later date, and to the field of biology in terms of being deprived of a steady flow of adequately prepared teachers and researchers. The afternoon session will consider the role of biology in the general education of students, chiefly those who at pres- ent are exposed to few (if any) science courses. In an age when science (and biology) has such a decided impact on everyday affairs, we can no longer afford a scientifically naive electorate. Henry Koffler, Martin W.

Moore (7 Brookside Circle, Bronxville, N.Y.). The Alpha Epsilon Delta Symposium will present a program outlining the Changing Patterns in Medical Edu- cation anticipated in the next decade. The philosophical and pedagogical objectives of the medical curriculum in coping with the current medical knowledge explosion will be discussed with emphasis on the place of the curriculum in the overall training of the physician and the need of the curriculum to develop study and learning habits that will enable the student to continue his medical education throughout his professional life. The results of the current studies on the learning problems of medical students will be analyzed and evaluated. Representatives of three medical schools—one still in the developmental stage: another just getting under way; and the third a well established school—will review the innovations and changes under development in their curricula. An informal panel discussion will follow with the speakers answering questions from the audience. The symposium will be summarized with a critical appraisal of “Tomorrow’s Medical School Applicant.” All persons interested in medical and premedical education and the preparation of students for a career in the health professions are invited and urged to attend this program. ; Ralph D.

Stephens (University of Cali- fornia, Irvine). Developments in the field of physiology have -been of overwhelming importance, both theoretical and practical, in shaping the development of biology in this century. The pace of these developments is such as to force continuing attention to the new way in which physiological information is coordinated with other topics to which students of biology should be exposed. Interesting and pressing matters of concern are rarsed by such facts as the tremendous proliferation of information in the various branches of physiology, a significant overlap of interests with such areas as biochemistry and biophysics and ultrastructure, and the increasing emphasis on quantitative approaches to biological problems at all levels of organization.
