As already announced [Trans, v. 35, p. 863], a Symposium on Applied Solar Energy will be held in Phoenix, Arizona, November 1–5, 1955, under the sponsorship of the Association for Applied Solar Energy, the Stanford Research Institute, and the University of Arizona. The program includes outstanding scientists working in this field from all parts of the country and from Australia, Israel, England, South Africa, France, Japan, and perhaps other countries.
