The Symposium on "Transport through Membranes : Carriers. Channels and Pumps" Inaugurates the third decade of the Jerusalem Symposia. It enlarges substantially their conceptual scope by Introducing a new subject not treated there previously. In fact. It Is a topic particularly well suited for the general object of these International meetings which Is to reassemble In an exhaustive Interdisciplinary discussion chemists. physicists and biologists. theoreticians and experimentalists. The main theme of the Symposium was the presentation and evaluation of the most up-to-date data on the structural and dynamic aspects of transport through membranes within the three main pathways: through carriers. channels and pumps. This goal was fully achieved thanks to the participation of a most outstanding assembly of world's experts In the field. We wish to thank Madame Pullman. the real organizer and mainspring of this meeting. for having composed a most exciting and excellent program and for carrying It out successfully. As the twenty preceding ones this Symposium was held under the auspices of the Israel Academy of Sciences and Humanities and the Hebrew University of Jerusalem. It was sponsored by the Instltut de Blologle Physlco Chimique. Fondatlon Edmond de Rothschild of Paris. We wish to express once again our gratitude to the Baron Edmond de Rothschild for his constant and generous support which makes this continuous endeavour possible.
