One of the manifold activities of Unesco, its Science Cooperation Office for Latin America, has recently prepared a report on the activities it engaged in during 1952 which gives a good idea of the magnitude of its contribution to the scientific development of this region. The report has been distributed in this country by the U.S. National Commission for Unesco. The chief categories into which the work of the Office falls are the coordination and development of scientific research, teaching and dissemination of science, and scientific documentation. A staff of twelve under Dr. A. Establier is located in Montevideo, Uruguay, to carry out these missions.
